Purus Labs - Muscle Marinade Preworkout/Intraworkout Drink Mix Grape Juice - 1.22 lbs.

Muscle Marinade Grape Juice by Purus Lab is a preworkout/intraworkout drink mix. Muscle Marinade  for high intensity exercise performance and acute exercise recovery. Muscle Marinade with 27 true serving and zero fillers. No pixy dust proprietary blends like Purus Labs competition uses to disquise their underdosed formulas. Purus Labs uses Only ingredients with clinically significant human research justifying their inclusion. Uses these ingredients at the exact dosage used in these research studies proving their effectiveness.

Consider Muscle Marinade the anomaly. It was systematically forged from science and research by real scientists and athletes, boasting an ensemble of performance enhancing and recovery stimulating ingredients supported by peer reviewed and published human scientific data. Taking it a step further, Muscle Marinade includes the clinically supported effective dosage of each ingredient every one scoop serving. NO OTHER COMPANY'S PRODUCT can match these claims. All facets of exercises performance and recovery are addressed within Purus Labs formula including increasing high intensity power output and muscular work, boosting mental acuity, enhancing fluid balance and hydration, reducing cortisol and free radical damage, enhancing cellular immunity, and facilitating maximal post exercise protein synthesis. Marketing does not propel or sustain Purus Labs products; Efficacy and Results do. 

  • Greater ATP Resynthesis generates increased power output
  • Intracellular Carnosine Enhancement for prolonged endurance
  • Anticatabolic Insulinogenic Action leads to great net protein accretion
  • Controlled Sympathomimetic Action leads to greater net protein accretion
  • Electrolyte Balancing Hyper-Hydration induces vasodilatory support and nutrient transport
  • Cortisol Reducing Antioxidant Action prevents muscle catabolism

The preworkout category has long been riddled with ineffective, underdosed products lacking scientific validation.  Companies do zero research yet pump tons of marketing dollars into convincing consumers their product is the best available.  Typically, they design lengthy and purposely confusing nutrition panels, haphazardly concoct pixie dust proprietary blends masking their cheap formulas, and load half the container with filler attempting to fool consumers into thinking they are getting more.




INTRODUCING MUSCLE MARINADE
Muscle Marinade represents a true breakthrough in the supplement industry with a specific focus on pre workout nutrition. As outlined above, Muscle Marinade was engineered using a detailed, systematic, and scientifically sound approach including only those ingredients supported by peer-reviewed and published scientific data in human subjects (in addition to strong anecdotal evidence) and included at the dosage used in the clinical research studies. The ingredient matrix comprising Muscle Marinade addresses all components related to both exercise performance and exercise recovery. Performance-related factors include mind/ muscle stimulation and energy production, hydrogen ion buffering, electrolyte balancing and hydration, and enhancement of muscle power and endurance. Recovery-related factors include insulin release and nutrient shuttling, cortisol reduction, protein anabolism, enhancement of cellular immunity, and improved health and antioxidant defense. Collectively, the ingredients provided within Muscle Marinade serve a dual purpose: 1) to improve acute exercise performance and 2) to facilitate post-exercise recovery.

What Makes Muscle Marinade Different?
As stated above, unlike other products within the pre workout category, Muscle Marinade contains only those ingredients supported by peer-reviewed and published scientific data in human subjects, in addition to anecdotal evidence for effect. Additionally, all ingredients included are at dosages used in the clinical research studies and are fully disclosed on the nutrition panel either by individual ingredient or by the specific ingredient class. While the actual number of ingredients contained within Muscle Marinade is lower than most other pre workout products on the market, it is important to note that the gram amount of active ingredients is much higher than most other products in this class. After all, as established throughout this paper, “quality and then quantity” of effective ingredients is much more important than sheer quantity of random individual ingredients. What good does it do to add 50 mg of a proven effective ingredient when the clinical studies report an effect only when used at 1000 mg? For many companies it increases the number of ingredients on the nutrition panel and allows them to hype the ingredient based on the original research using the effective dosage. Likewise, what good does it do to add 2000 mg of an absolutely useless ingredient that has been shown time and time again to have no impact on exercise performance or recovery, or that has never been tested at all for that purpose? For many companies it not only increases the number of ingredients on the nutrition panel but it also increases the gram weight of the serving, and hence the weight of the container. These companies bank on the fact that the consumers will do no real research of their own and instead be naively overwhelmed by a lengthy and confusing nutrition panel, a “heavy jug”, and fancy marketing within the major magazines. Such practices are commonplace within the sport supplement industry and, for these aforementioned reasons, give sport nutrition supplements a bad name.

This practice is akin to a bodybuilder going to a new gym and seeing that they have 12 different machines to train legs, all of which are shiny, appear effective, and have fancy pictures posted on them for instruction. Rather than waste time using each of the 12 machines for one set over the course of the workout, the bodybuilder decides to stick with what they knows works well and simply knocks out 10 sets of barbell squats and stiff leg deadlifts. Using this approach, the bodybuilder recognizes that it’s not about the total number of ineffective exercises that matters; it’s about selecting a small number of effective exercises and applying the correct “dosage” of effort. In straightforward terms: Quality exercise done at the correct volume = effectiveness. The same principle applies with nutritional supplements: Quality ingredients provided at the correct dosage = effectiveness. It’s really that simple, yet most companies don’t have the initiative or integrity to toil over stacks of research literature to identify just what these quality ingredients actually are.

Also, many products contain large amounts of maltodextrin, which essentially comprises onethird to one-half of the entire gram weight. This is an inexpensive way for companies to increase the serving size and container weight while minimally increasing their costs. This is a trick to make consumers think they are getting more for their money. Another trick most companies selling pre workout products frequently use lies within their “supposed servings” per container. Many products claim to have 40 or 50 servings/scoops on the front of their product label, but when the consumer reads the directions for use they are instructed to take 2 or even 3 servings/scoops as opposed to the advertised 1 scoop (look on your current product’s label). This scam is used to convince consumers that they are getting more for their money. Muscle Marinade contains 27 “true” servings, and each serving is designed to include the maximum clinically-supported efficacious dose of each performance/ recovery-impacting component and is devoid of inactive and useless ingredients and fillers. Therefore, only one serving/scoop is needed at any one time. No guessing. No experimentation. No false advertising. In fact, one serving is so substantial in strength that additional servings are strongly discouraged.

The text below provides specifics related to the Muscle Marinade formula. It is in no way meant to represent a detailed discussion of all available evidence for the highlighted ingredients. Readers are encouraged to review the reference data provided at the end of this paper for additional information. While dosages of individual ingredients vary considerably across studies and not every study using a particular ingredient has been met with positive effects, consumers should feel confident that a great deal of unbiased attention has been put into the decision to include the below-discussed ingredients (as well as the exclusion of other commonly used ingredients). All those mentioned and included within the formula have been proven to be effective in human subjects with oral consumption based on peer-reviewed scientific reports and anecdotal (in the gym) evidence. Moreover, as consistently mentioned, the dosage of each ingredient within Muscle Marinade matches the dosage used in these clinical studies. This is indeed a novel concept in the field of sport nutrition supplements. Because the referenced studies often provide ingredients to subjects on a daily basis over the course of days or weeks (e.g., creatine, beta alanine), it should be understood that the below-discussed effects for a given ingredient may only be observed after continued use of that ingredient. It is assumed that individuals will use Muscle Marinade on a daily basis along with their normal nutrition and exercise training program in order to reap the product’s full benefits.

Muscle Marinade: Energy Production, Stimulation, and Exercise Performance

Creatine—Overview
Creatine is a naturally occurring nitrogenous organic compound produced in the human body from the amino acids arginine, glycine, and methionine. While production occurs primarily in the kidney and liver, creatine is transported in the blood and taken up by other tissues (skeletal muscle primarily). To date, aside from carbohydrate, creatine is likely the most well-researched sport supplement in history. In fact, a PubMed search performed on 11/12/09 using the term “creatine and exercise” returned 3217 articles, while the term “creatine and exercise performance” returned 588 articles. Clearly, this is a well-researched ingredient and is thought to pose no adverse effects to healthy individuals (Poortmans and Francaux, 2000).

While the effects of creatine supplementation are multiple, including antioxidant activity, maintenance of neuronal health, and improved cardiac muscle performance, the effect of most interest related to exercise performance in otherwise healthy individuals is improved performance during high intensity anaerobic exercise (Hespel and Derave, 2007). Creatine aids in adenosine triphosphate (ATP) resynthesis and can lead to high intensity performance improvements as demonstrated in literally hundreds of scientific studies. Creatine supplementation has also been associated with enhanced muscle hypertrophy, which may relate to satellite cell proliferation, as well as myogenic transcription factors and insulin-like growth factor-1 signaling. Other evidence indicates that creatine could enhance muscle glycogen accumulation and glucose transporter (GLUT4) expression. Positive findings for creatine are noted for both healthy and diseased populations. Although noted in animals and not human subjects, oral creatine supplementation has been shown to significantly increase carnosine (+88%) and anserine (+40%) content in skeletal muscle, which coincides with improved resistance to contractile fatigue (Derave et al., 2008). The physiological effect of carnosine is discussed below in the section on beta alanine.

Creatine—Form
Much discussion exists related to the optimal form of creatine to be used. While creatine monohydrate is certainly the most well-researched and most common form available, other forms such as creatine ethyl ester (CEE), di-creatine malate, tri-creatine citrate, creatine gluconate, creatine taurinate, creatine pyruvate, creatine l-pyroglutamate, and “pH balanced” creatine among others are currently marketed throughout the sport supplement industry. In addition, some companies are now using an agent known as creatinol-O-phosphate within their products. Although this agent is not technically creatine, some companies proceed to falsely market it as a super-creatine. Most reports for COP were published in the late 1970s in the journal entitled Arzneimittelforschung, and most studies focus on cardiac function with COP. A PubMed search indicates that there is only one study dealing with physical performance (Nicaise, 1975) and included 50 female in-patients ranging in age from 58-96 years. Patients were treated intramuscularly and intravenously (not orally) with 2 ampoules of 500 mg each of COP. Muscular strength was then measured by having women squeeze a bulb in each hand 5 times. Results were of statistical significance but were rather meaningless from a physiological perspective (e.g., sum of 85.86 vs. 90.40 (kg/cm2)10-1 for placebo and intravenous COP, respectively; sum of 82.00 vs. 88.60 (kg/cm2)10-1 for placebo and intramuscular COP, respectively). Perhaps companies have other data to support their use of COP in their products (although they must be quite obscure, because these are not readily available via PubMed). If companies are basing their use of COP on the particular study described above and assuming that because intramuscular or intravenous COP increased hand strength to a minor extent in elderly in-patient women that oral intake of COP will lead to increased strength in young healthy men and women, they really need to reevaluate their formulation guidelines or do some real applied research using this ingredient. Inclusion of COP within a formula designed for young healthy men and women based on the data presented above is an absolute joke. Unfortunately, this is no exception in this industry.

While the more modern creatine versions are often heavily advertised so as to appear superior, there exists very little evidence that any of these creatine forms are better than creatine monohydrate, despite their substantial costs. For example, a study presented at the National Strength and Conditioning Association meeting in 2007 indicated that CEE was actually less stable than creatine monohydrate and experienced an accelerated breakdown to the byproduct known as creatinine (Child and Tallon, 2007). Other work agrees with this finding (Spillane et al., 2009). Authors comparing CEE with creatine monohydrate have concluded “when compared to creatine monohydrate, CEE was not as effective at increasing serum and muscle creatine levels or in improving body composition, muscle mass, strength, and power.” Investigators from another recent study concluded that “the half-life of CEE in blood is on the order of one minute, suggesting that CEE may hydrolyze too quickly to reach muscle cells in its ester form (Katseres et al., 2009). Collectively, these findings indicate that CEE is not a desired form of creatine to be used as a nutritional supplement.

Similar negative findings have been noted for the supposed “pH balanced” creatine known as Kre-Alkalyn™ (Tallon and Child, 2007). Marketers claim that this product, unlike creatine monohydrate, is stabilized and will not undergo conversion into creatinine. To the contrary, investigators noted that the rate of creatinine formation for creatine monohydrate was <1% of the initial dose, indicating that creatine monohydrate is actually very stable under acidic conditions. Additionally, the Kre-Alkalyn™ resulted in 35% greater conversion to creatinine than creatine monohydrate.

As for other creatine forms, very little research has been conducted to determine differences in either absorption or effectiveness as compared to creatine monohydrate. Therefore, at the present time, there is little to no evidence to support the use of forms other than creatine monohydrate. One recent study determined the plasma creatine appearance in men and women assigned to ingest a single dose of isomolar amounts of creatine (4.4 grams) as creatine monohydrate, tricreatine citrate, or creatine pyruvate (Jäger et al., 2007). The investigators noted that while peak concentration and area under the curve of plasma creatine was highest for creatine pyruvate, there was no difference between the estimated velocity constants of absorption or elimination between the three creatine forms. These investigators concluded that “differences in bioavailability are thought to be unlikely since absorption of creatine monohydrate is already close to 100%. The small differences in kinetics are unlikely to have any effect on muscle creatine elevation during periods of creatine loading.” This is especially true considering that oral creatine monohydrate is rapidly and efficiently absorbed, a fact established over 10 years ago (Vanakoski et al., 1998).

Despite these solid findings related to the already excellent absorption of creatine monohydrate, new products continue to be developed in an attempt to further improve creatine absorption. One such product (BIOCREAT) was recently studied and reported to yield similar adaptations in both muscle strength and lean mass as compared to a creatine+carbohydrate supplement, with no significant differences noted between the two creatine conditions (Lewing et al., 2009). Another form recently studied is polyethylene glycosylated creatine (creatine bound to polyethylene glycosylate [PEG]), hypothesized to result in increased creatine absorption and uptake into muscle cells (Herda et al., 2009). Subjects were assigned to a placebo condition, 1.80 or 3.60 grams of PEG (providing 1.25 and 2.50 grams of creatine, respectively), or 5 grams of creatine monohydrate per day for 30 days. Although the dosage of actual creatine was less in the PEG conditions, the results indicated that the creatine monohydrate condition yielded similar or better results in terms of lean body mass and performance improvement as compared to the PEG. These data reinforce the fact that creatine monohydrate, despite being considered “old school”, yields favorable results comparable or better than those observed with “new school” creatine forms.

Another new product, CON-CRET (Creatine HCL) marketed by ProMera health, is also being heavily advertised as a superior form of creatine in terms of solubility and absorption in the bloodstream. However, regardless of whether or not this is true (see below for more info), the company makes no claim related to the variable of real importance—skeletal muscle creatine uptake. While the product website indicates two university studies were conducted demonstrating this enhanced absorption, no reference data are provided, and no such studies are readily available via PubMed. Therefore, it is unknown whether or not the findings being claimed by ProMera health can stand up to the scrutiny of peer review. While it is possible that we may someday see published scientific evidence in support of CON-CRET (to date we simply have testimonials—which are alone, next to worthless in the scientific world), the question remains as to how much greater benefit a consumer could experience using this product (or any other novel creatine product for that matter) in order to justify the significant increase in cost as compared to creatine monohydrate. Aside from this important consideration, the fact that ProMera health boldly and deceptively states on their website, “CON-CRET is 59-times more potent than creatine monohydrate,” and “CON-CRET offers steroid-like results in strength, endurance and muscle recovery” is concerning to say the least. If the first claim were true, one serving (1500 mg for a 200 pound man) of CON-CRET would be equal to 88,500mg of creatine monohydrate. It is also stated on the website that one serving has potency equal to 5-10 grams of creatine monohydrate. There is clearly a discrepancy here within ProMera’s own claims. Such ridiculous and contradicting statements lead me to believe that this is yet another product fueled by pure marketing and hype, not hard scientific evidence.

As alluded to above, it should be understood that even if small differences in absorption time or concentration were noted between a novel form of creatine and creatine monohydrate, the question a consumer should have is “Who cares?” What real difference does this make considering creatine monohydrate already has absorption of close to 100% (Jäger et al., 2007)? Is it really worth paying more in order to use one of these hyped up novel creatine forms only to maybe experience a 5-10% increased plasma appearance rate? The rate of appearance of creatine is irrelevant anyway considering it is intramuscular and not plasma creatine that is important. Consumers also need to keep in mind that it is not the creatine taken immediately prior to each workout that is assisting in that particular workout; rather, it is the creatine that has been taken repeatedly over time that is now built up within the muscle that can provide for a benefit. Taking the daily dosage of creatine prior to (or immediately following) exercise makes good sense simply based on the fact that creatine transport into muscle may be enhanced due to the increased blood flow (Candow and Chilibeck, 2008) and possibly the increased activity of creatine transport proteins associated with acute exercise.

Aside from acute exercise, intake of creatine along with carbohydrate (usually simple sugars at high dosage; the basis of many creatine+carbohydrate products) has been shown to enhance creatine absorption in skeletal muscle (Green et al., 1996) and may enhance the effectiveness of creatine supplementation. Therefore, if adding extra carbohydrate to the diet does not interfere with daily caloric requirements, combining creatine and carbohydrate supplementation may be something to consider. That being said, PURUS LABS has chosen not to include carbohydrate within Muscle Marinade, as more emphasis is placed on actual active ingredients rather than on inexpensive fillers. After all, carbohydrates are an inexpensive and readily-available addition if one chooses to include them.

Creatine—Dosage
Oral supplementation with creatine has been reported to substantially elevate the creatine content of human skeletal muscle. The most common dosage schedule in research studies has included a “loading” phase of 20 grams per day taken in 4 dosages of 5 grams each for a period of 5-7 days. Following this, creatine saturation in skeletal muscle can be maintained at a daily dosage as low as 2-5 grams for most individuals (Preen et al., 2003), although the International Society of Sport Nutrition (ISSN) has recommended a daily intake as high as 0.1 gram/kg body mass/day (Kerksick et al., 2008). As with all dietary supplements, individual needs may vary. As mentioned above, it has been suggested that creatine ingestion proximate to resistance exercise may be more beneficial for increasing muscle mass and strength than ingestion at times distant to the exercise session, possibly due to increased blood flow and therefore increased transport of creatine to skeletal muscle (Candow and Chilibeck, 2008). Hence, inclusion of creatine within a pre workout supplement appears logical, and this is why creatine is contained within Muscle Marinade.

Beta alanine
Beta alanine, also referred to as 3-aminopropanoic acid, is a non-proteinogenic amino acid. Although initially discovered over 100 years ago, research with beta alanine pertaining to exercise performance in human subjects is relatively new, with the first scientific paper published just a few years ago. The plasma concentration of beta alanine is significantly and rapidly elevated following oral intake of beta alanine ranging from 20-40 mg/kg body mass (Harris et al., 2006). Moreover, the muscle carnosine (beta-alanyl-l-histidine) concentration, comprised of both beta alanine and histidine, is significantly increased when beta alanine is provided at a dosage of 3-6 grams per day (Harris et al., 2006). Carnosine helps to stabilize muscular pH by acting as a buffer for hydrogen ions that are released as a result of high intensity exercise. While not all studies have reported positive findings, the majority of work involving beta alanine supplementation indicates a significant performance-enhancing effect with regards to high intensity exercise.

One concern expressed in relation to beta alanine is the mild “prickling/tingling” sensation often felt soon after ingestion (e.g., as soon as 15 minutes and often lasting up to 60 minutes). This is referred to as parethesia, and is thought to be caused by beta-alanine binding to nerve receptors and causing them to fire. While this is well-tolerated by some users, others would prefer not to feel this prickling/tingling. In a study involving acute ingestion of beta alanine at dosages of 10, 20, and 40 mg/kg body mass, extreme tingling was noted with the 40 mg/kg body mass dosage, while only moderate tingling was experienced with the 20 mg/kg body mass dosage (Harris et al., 2006). Moreover, the increase in plasma beta alanine from the 10 to 20 mg/kg body mass dose was 6-8 fold, while the increase from 20-40 mg/kg body mass was only 2.2 fold. Peak plasma concentration of beta alanine occurred within 30-40 minutes following acute ingestion, and a subsequent study indicates that chronic supplementation (e.g., 15 days) does not affect this. Additionally, less beta alanine is lost in the urine following a 20 vs. 40 mg/kg body mass dosage. Therefore, based on the relatively small further increase in plasma beta alanine following ingestion of a single dosage from 20 to 40 mg/kg body mass, the fact that dosages as low as 2 grams per day have been found to be efficacious in scientific investigations (Van Thienen et al., 2009), and the fact that higher dosages of beta alanine lead to greater parethesia, Muscle Marinade contains a dosage of beta alanine equivalent to 25 mg/kg body mass for an 80 kg man. This dosage should minimize profound parethesia and is close to the dosage previously reported to increase muscle carnosine content by ~40% following four weeks of ingestion (Harris et al., 2006).

As discussed above in the section on creatine, although noted in animals and not human subjects, it has been reported that creatine intake alone results in enhanced muscle carnosine content (Derave et al., 2008). Considering this evidence, using an adequate dosage of creatine along with beta alanine may justify using a slightly lower dosage of beta alanine. As with creatine, it has been suggested that beta alanine uptake into skeletal muscle to form carnosine may be enhanced by carbohydrate intake due to the insulin response from such feeding. Again, users may add carbohydrate as they see fit.

Betaine
Betaine (chemically known as 2-(Trimethylammonio) ethanoic acid, hydroxide, inner salt) is an osmolyte (i.e., protects the cells against dehydration), an antioxidant agent, as well as a methyl group donor serving a chief purpose of lowering homocysteine (Olthof and Verhoef, 2005), a known risk factor for cardiovascular disease (Boushey et al., 1995). The B-vitamins folic acid (B9), B12, and B6 are often used for this same purpose of lowering homocysteine. As a methyl group donor, betaine has a potential effect on creatine biosynthesis by providing a methyl group to guanidinoacetate via methionine that can synthesize creatine in skeletal muscle (du Vigneaud et al., 1946).

In regards to exercise performance, a few studies have been conducted over the past few years using betaine (anhydrous form). The dosage of betaine in these studies has been 2.5 grams per day. Muscle endurance (Hoffman et al., 2009) as well as muscular power and force (Maresh et al., 2007) have been reported to increase following 14 days of betaine supplementation. Mechanistically, betaine may improve exercise performance by providing antioxidant activity, maintaining cellular hydration, and increasing blood flow, the latter possibly mediated by the effect betaine has on increasing NO (unpublished data). Although betaine is relatively new to the sport nutrition market, PURUS LABS believes that this ingredient has promise as a sport supplement. For this reason it is included within Muscle Marinade at the proper, researchsupported dosage.

1,3,7-trimethylxanthine
Commonly referred to as caffeine, 1,3,7-trimethylxanthine is very well studied in relation to exercise. Findings for improved aerobic (Ganio et al., 2009) and anaerobic (Davis and Green, 2009) exercise performance are common with acute ingestion of caffeine prior to exercise (typically 30-60 minutes prior). Multiple mechanisms are associated with caffeine’s ergogenic effects including improved cognitive performance, increased catecholamine secretion and lipolysis, enhanced calcium mobilization and phosphodiesterase inhibition, enhanced Na+/K+ pump activity to enhance excitation contraction coupling, and adenosine receptor antagonism. While individual response to caffeine varies, dosages in the literature have generally ranged from 3-6 mg/kg body mass, and individuals who do not frequently use caffeine appear to respond to the greatest extent (Ganio et al., 2009).

2-amino-4-methylhexane
The ingredient 2-amino-4-methylhexane is a component of geranium oil and appears to provide a sympathomimetic effect in human subjects. That is, it mimics the effects of the sympathetic nervous system such as the chemicals epinephrine, norepinephrine, and dopamine. In this way it may stimulate energy release and provide a feeling of euphoria. Very little is known about this ingredient, but anecdotal reports are impressive. It should be noted that this is the one ingredient contained within Muscle Marinade that is not yet supported by peer-reviewed published clinical data. However, a controlled laboratory study investigating the effects of 2-amino-4- methylhexane combined with caffeine on resistance exercise performance in a sample of resistance trained men was recently completed (unpublished data). The results indicate that the simple combination of 2-amino-4-methylhexane and caffeine is as effective as the top selling pre workout powders currently being sold on the sport nutrition market in terms of enhancing upperbody muscular power and endurance (using bench press throws and bench press exercise to fatigue, respectively). These findings reinforce the position of PURUS LABS that the correct ingredients provided at the correct dosages are much more effective than the sheer number of ingredients. That is, 2-amino-4-methylhexane and caffeine (mixed into 16 grams of maltodextrin in an attempt to match the carbohydrate content of other pre workout powders used for comparison) was similar in effectiveness as the other products which contained 35-65 individual ingredients! This is a great example of the “window dressing” hype within the sport supplement industry. It is truly a shame that most companies are more concerned with beefing up their product label with worthless ingredients used at ridiculously low dosages, rather than providing a solid dosage of real ingredients that actually have been shown in human subjects to yield an effect.

In addition to the laboratory study mentioned above, the dosage of 2-amino-4-methylhexane contained within Muscle Marinade is based on pilot testing in a variety of healthy men and women using this ingredient either alone at varying dosages, as well as in combination with caffeine. Subjective reports related to subjects’ “perceived feeling of energy and focus” as well as subjects’ actual exercise performances have guided the dosing of this ingredient. Indeed, further research is warranted in relation to 2-amino-4-methylhexane and exercise performance alone and in combination with other performance aids–to scientifically validate the inclusion of this ingredient.

Electrolytes
Electrolytes are ionized salts (dissociated into positive and negative ions) found within body fluids. Electrolytes serve the function of maintaining concentration and charge differences across cell membranes and are involved in neural and muscle cell functioning. In relation to dietary supplements, electrolytes are most commonly contained within sport drinks primarily for rehydration purposes and maintenance of blood flow. The chief electrolytes contained within such products appearing to have an effect on hydration status following strenuous physical exercise are sodium, chloride, potassium, and magnesium. Coupled with adequate fluid intake before, during, and following an acute exercise bout, the electrolyte mix contained with Muscle Marinade aids in maintaining optimal hydration. This effect may be assisted by the addition of the osmolyte betaine (as discussed above).

One other consideration, once again, is the ingestion of a dilute (6-10%) carbohydrate solution during the exercise bout. This will not only improve hydration status (Evan et al., 2009; von Duvillard et al., 2008) but will also serve the purpose of enhancing cellular immunity (Braun and Von Duvillard, 2004; Nieman et al., 2001) possibly working in conjunction with other immunesupporting agents within Muscle Marinade such as vitamin C and zinc. It should be understood that hypohydration (loss of fluid) is associated with increased cortisol and possibly increased protein catabolism/tissue breakdown (Judelson et al., 2008). Therefore, efforts to maintain hydration status during and following exercise should be undertaken by all serious trainees. Muscle Marinade imparts a precise blend of potassium, magnesium, sodium, and chloride to further compliment its performance-enhancement properties.

Muscle Marinade: Exercise Recovery

Essential Amino Acids
Amino acids are critical to physiological function and have multiple roles within biological systems. There are both essential and non-essential amino acids; the former meaning that the body cannot synthesize these from other compounds at the level needed for normal growth; they must be supplied in the diet. Perhaps the most notable function of amino acids is to act as building blocks for proteins. Proteins are required for muscular growth and repair and are the dietary focus of most bodybuilders and fitness enthusiasts. While it is well accepted that active individuals require significantly more protein than their sedentary counterparts (Rodriguez et al., 2009), an often overlooked component related to protein intake is the specific timing of amino acid ingestion in the precise combination with relation to an acute bout of resistance exercise. Specifically, several studies support the use of a precise essential amino acid mixture prior to resistance exercise. These investigations have included an oral dosage of essential amino acids equal to 6 grams, taken both with (Tipton et al., 2001) and without (Bird et al., 2006a; 2006b; 2006c) carbohydrate. Findings from such studies indicate enhanced protein synthesis with ingestion of essential amino acids before resistance exercise to a greater extent than compared to essential amino acid ingestion post-exercise (Tipton et al., 2001; Wolfe, 2001). Post-exercise insulin has also been noted to be higher following intake of an essential amino acid mixture (Bird et al., 2006b) while both 3-methylhistidine (a marker of protein breakdown) (Bird et al., 2006b) and cortisol have been noted to be lower (Bird et al., 2006c). Taken together, these results suggest an “anti-catabolic effect” of essential amino acid ingestion.

Aside from acute intake, other work indicates that chronic (i.e., daily) intake of a precise 6 gram essential amino acid mixture attenuates 3-methylhistidine excretion during the days following strenuous exercise (Bird et al., 2006a). As with many aforementioned ingredients, it should be noted that carbohydrate added to the essential amino acid mixture provides additional anticatabolic activity (Bird et al., 2006b). Therefore, if a diluted (6-10%) carbohydrate solution is tolerable from a caloric standpoint, Muscle Marinade could be mixed into a carbohydrate drink (e.g., juice) as opposed to water. An alternative would be to add carbohydrate powder (30- 40 grams) to one scoop of Muscle Marinade and mix in water.

Vitamins and Minerals—Overview
According to the Center for Disease Control and Prevention, “vitamins are organic substances made by plants or animals, while minerals are inorganic elements that come from the earth. Soil and water are absorbed by plants and animals, and humans absorb minerals from the plants they eat.” While moderate levels of vitamins and minerals are necessary for normal growth, development, and metabolic processes, higher amounts of certain vitamins and minerals have been shown to provide protection against various stressors. One such stressor is heavy physical exercise. In an attempt to combat the stress caused by intense physical exercise, the use of antioxidant vitamins (C and E) and minerals (zinc and selenium) as well as complementary Bvitamins (B6, B9, and B12) may be considered.

Ascorbic acid, commonly known as vitamin C, is a water soluble vitamin with multiple physiological properties. It is one of the most well-researched antioxidants, particularly related to exercise-induced free radical production. When free radical production exceeds the body’s antioxidant defense mechanisms (by way of both endogenous antioxidant enzymes/thiols and exogenous antioxidant vitamins/minerals consumed through dietary sources) a condition referred to as oxidative stress may occur. Oxidative stress ultimately has the potential to damage cellular structures including phospholipid membranes, protein, mitochondria, and DNA (Valko et al., 2007). While a low level of free radical production is actually beneficial and necessary for normal physiological function, excessive radical production, which is common with strenuous physical exercise (Bloomer, 2008), can directly impair muscle contractile function and force. This may occur via defects in excitation-contraction coupling (Goldhaber and Qayyum, 2000) and lead to greater fatigue rates in skeletal muscle (Juel, 2006). An attempt to curtail this impairment is generally the rationale for inclusion of supplemental antioxidant vitamins/minerals for athletes.

While vitamin C has multiple physiological properties beyond the scope of this discussion (Deruelle and Baron, 2008), when considering the above, several studies have included vitamin C (typically at a dosage of 1000 mg/day and often in combination with alpha tocopherol [vitamin E]) in an attempt to lessen the oxidative stress and associated loss in muscle function. Although not all studies have noted effects for vitamin C in this regard, several have been met with positive findings for at least some biochemical or functional measures, as reviewed in detail by Fisher-Wellman and Bloomer (2009). In addition to acting as an antioxidant agent in the attenuation of exercise-induced oxidative stress, vitamin C has been reported to reduce the rise in circulating cortisol following exercise (Carrillo et al., 2008), as well as function as an immuneboosting nutrient (Wintergerst et al., 2005) with effects on reducing the incidence of the common cold (Hemilä, 2004) and post-exercise upper respiratory tract infections (Peters et al., 1993). For these reasons, after careful review of the available literature, vitamin C intake is suggested at a daily dosage of 1000 mg (Deruelle and Baron, 2008) and is included within Muscle Marinade at this exact dosage. Intake of vitamin C at this dosage is well-absorbed and has been shown to significantly elevate plasma vitamin C concentration (Bloomer et al., 2006).

Vitamins and Minerals—d-alpha-tocopherol (natural vitamin E)
The lipid soluble vitamin referred to as alpha tocopherol works in conjunction with vitamin C (as well as other antioxidants such as selenium, zinc, and glutathione) in a process known as redox cycling. These antioxidants maintain each other in their reduced and active form. For this reason, inclusion of an antioxidant “complex” within a dietary supplement is most appropriate. Alpha tocopherol is typically used to denote vitamin E due to the fact that alpha tocopherol is the only form of vitamin E that is actively maintained in the body. However, it should be mentioned that a more correct depiction of vitamin E is the inclusion of alpha, beta, gamma, and delta tocopherols and tocotrienols (mixed tocopherols/tocotrienols). While results are mixed, some evidence indicates that the combination of all may best produce an antioxidant effect. Regardless, one finding related to vitamin E is common: Natural vitamin E (d-alpha tocopherol) is better absorbed and shows higher bio-potency (1.5-2 fold) than synthetic vitamin E (dl-alphatocopherol) (Hoppe and Krennrich, 2000). This may be due to the fact that the natural form consists of one isomer; in contrast, the synthetic form contains eight different isomers of which only one is the same as the natural form. The other seven isomers have been noted to range in potency from ~20 percent to 90 percent of natural vitamin E (d-alpha-tocopherol). Considering this, effective dosages of natural vitamin E can be lower than synthetic and have ranged from just slightly higher than the Recommended Daily Allowance (RDA) of 15 mg/day to several hundred mg/day. Due to the concern over high intake of lipid soluble vitamins, in particular vitamin E (Greenberg, 2005), the fact that vitamin E as low as 60 mg/day has been reported to provide effects (Meydani et al., 1997), and that many scientists believe that a dosage of 100IU (67 mg) to 200IU (134 mg) of natural d-alpha tocopherol is adequate (although this is refuted by some reports—see Roberts et al., 2007), Muscle Marinade contains a judicious dosage of vitamin E thought to be both safe and clinically effective when combined with the other antioxidants within the formula.

Aside from working in conjunction with vitamin C and other antioxidants, vitamin E independently functions as an immune-boosting agent (Meydani et al., 1997), a potent chainbreaking antioxidant to inhibit the oxidation of cellular lipids, and serves to stabilize cell membranes (e.g., sarcolemma) in conjunction with zinc (Chien et al., 2006). This often results in less leakage of intracellular components such as creatine kinase following muscle-damaging exercise (Fisher-Wellman and Bloomer, 2009).

Vitamins and Minerals—Selenium
Selenium is a trace element essential in small amounts, but like all essential elements, it is toxic at high levels. Humans and animals require selenium for the function of a number of seleniumdependent enzymes including glutathione peroxidase (GPx). Glutathione peroxidase is a collective term for a family of enzymes with antioxidant activity serving to reduce potentially damaging agents such as lipid hydroperoxides into alcohol and hydrogen peroxide into water. In this process, the important antioxidant glutathione (GSH) is “used up” and oxidized to GSSG. The enzyme known as glutathione reductase then serves to reduce glutathione back to the active form (GSH). All of this occurs along with vitamin C and vitamin E in a process known as redox cycling. In this way, these antioxidants complement one another. In conjunction with vitamin C and vitamin E, Muscle Marinade contains a decisive dosage of selenium, the same dosage successfully used to combat exercise-induced oxidative stress (Goldfarb et al., 2005) and muscle damage/soreness (Bloomer et al., 2004).

Vitamins and Minerals—Zinc
Zinc is an essential trace element for all life forms playing roles in numerous aspects of cellular metabolism such as growth and development, the immune response, and neurological function. In conjunction with both vitamin C and vitamin E, zinc provides antioxidant and immune support with combination therapy commonplace in the literature (Huang et al., 2006; Wintergerst et al., 2006). Studies have repeatedly shown the beneficial properties of zinc as related to both antioxidant (Mocchegiani, 2008) and immune-stimulating function (Haase and Rink, 2009; Prasad, 2008). The dosage of zinc used in many studies has ranged from 15-50 mg/day. While zinc is used in many different forms (e.g., gluconate, picolinate, methionine), zinc methionine has been reported to have the greatest antioxidant activity (Bagchi et al., 1997) and superior bioavailability (Chien et al., 2006). This is, of course, the form of zinc utilized in Muscle Marinade.

Vitamins and Minerals—B-vitamins (B6, B9, B12)
B-vitamins are water soluble and important for a number of processes within the body involved in energy production (Woolf and Manore, 2006). Many common foods are fortified with Bvitamins, and a daily supplement is often recommended for individuals who do not eat adequate amounts of B-vitamin rich foods. The RDA for these vitamins is relatively low and can typically be met by consuming a good quality multivitamin. However, the requirements for B-vitamins may be increased by strenuous activity (Woolf and Manore, 2006). It has been recommended that pyridoxine HCL (vitamin B6) intake be calculated based on the protein intake (0.02 mg per gram of protein) while cyanocobalamin (vitamin B12) is usually recommended at 6 to 30 µg/day. Folic acid (vitamin B9) is recommended at 400 µg/day and often higher for women who are pregnant or who are of child bearing years. As with betaine (discussed earlier in this paper) the B-vitamins act to reduce levels of the sulfur-containing amino acid homocysteine, an intermediate of methionine noted to be linked to an increased risk of cardiovascular disease (Boushey et al., 1995). Therefore, B-vitamins serve the dual role in athletes of enhancing energy production and potentially decreasing the risk for cardiovascular disease. Considering the above, Muscle Marinade contains adequate amounts of B-vitamins necessary for measureable effects.
