Nutricology QuatreActiv Folate - 90 Vegetarian Capsules
Nutricology QuatreActiv Folate contains Quatrefolic, the glucosamine salt of 5-methyltetrahydrofolate (5-MTHF). Nutricology QuatreActiv Folate patented form of 5-MTHF has demonstrated greater bioavailability than the 5-MTHF calcium salt form. Nutricology QuatreActiv Folate also shows enhanced solubility and stability.
5-MTHF is an essential cofactor in the metabolism of the amino acid metabolite homocysteine. 5-MTHF also must be present in sufficient quantity for normal production of the neurotransmitters serotonin, melatonin, dopamine, epinephrine, and norepinephrine. These functions make 5-MTHF critical for both cardiovascular function and mood support.
Folic acid must be converted to its active forms to be used by the body. This is a multi-step biochemical process that occurs in the intestines and liver. In the presence of intestinal or liver dysfunction this conversion may not occur sufficiently enough to meet the body's needs. Furthermore, up to 60-percent of the U.S. population may have a genetic enzyme defect that makes it difficult for them to convert folic acid into active 5-MTHF. For these individuals and many others, 5-MTHF supplementation may be a more effective method of folate repletion.
- a breakthrough in folate supplementation
- the most bioavailable, active form of folate
- an excellent source of folate for pregnant women
- supports optimal cardiovascular and neurological function
- made without flowing agents that can inhibit bioavailability
Quality and Innovation – The NutriCology Tradition
For more than thirty years, NutriCology has been known for the highest quality, most hypoallergenic, and most cutting-edge nutritional supplements available. Physicians and healthcare practitioners around the world depend on NutriCology for their patients’ nutritional support. Originating with the ground-breaking oxidant/antioxidant work of Stephen Levine, Ph.D., NutriCology was one of the first to introduce truly hypoallergenic products to the market.
Superior Quality Control
Since 1979, NutriCology has used only the purest raw materials available, and has implemented strict quality control procedures in every stage of production, including inspection of raw materials, manufacturing, packaging, and storing. NutriCology is licensed by the California Department of Health Services, Food and Drug Branch, registration number 0021150.
NutriCology's products are manufactured under the recognized principles of current Good Manufacturing Practice (cGMP), brought into final form by the FDA in June 2007. The GMP standards are applied to a wide variety of procedures associated with the manufacturing of dietary supplements, including receiving, testing, and approval of raw materials, production, and process controls, laboratory testing of labeled and packaged finished product, distribution control and accountability, and shelf life expiration testing to ensure freshness and potency.
For many years they have used the same manufacturers to produce our powder formulas, capsules, tablets, softgels, gels, and liquid products to ensure consistency. All of their certified manufacturers meet or exceed cGMP requirements established by the FDA, as well as state and local regulations. In their facility in Alameda, California, their highly trained staff bottle, label, and ship their finished products. Their newly installed automatic bottling line has multiple built-in quality checks, such as weight verification and metal detection, to ensure all finished packaged products have the pre-determined physical count and are contaminant-free.
Independent Third Party Laboratories
In addition to NutriCology's in-house quality control department, they use certified independent analytical laboratories to test raw materials as well as finished products. All of their certified laboratories meet or exceed cGMP requirements. Their products are assayed for identity, purity and potency, and are confirmed to contain pre- determined amounts of the contents listed on every label. Microbial, pesticides/herbicides, aflatoxins, residual solvents, and heavy metals analysis are also conducted on all applicable products.
Procedures of Analysis
NutriCology utilize a number of advanced methods of analysis, including high performance liquid chromatography (HPLC), IR and UV-VIS spectroscopy, capillary electrophoresis (CE), inductively coupled plasma-mass spectrometry (ICP-MS), atomic absorption (AA), thin layer chromatography (TLC), and Fourier transform infrared spectroscopy (FTIR), along with biochemistry and wet chemistry techniques.
Unsurpassed Ingredient Quality
NutriCology uses only the purest and highest quality raw materials available. For example, they use only Nattokinase NSK-SD, the first nattokinase introduced into the U.S. market, which has established standardization and quality levels for all other nattokinase. Their MicroChitosan contains small-size chitosan oligosaccharide, and their Prima Uña de Gato contains TOA-free Cat’s Claw.
Taber’s Medical Dictionary defines “hypoallergenic” as: “Diminished potential for causing an allergic reaction”. they define hypoallergenic as “free of all common allergens”, specifically, wheat, corn, soy, gluten, yeast, dairy, eggs, fish, crustacean shellfish, tree nuts, and peanuts. Many very sensitive individuals who react to supplements in general are able to tolerate NutriCology products.
Since NutriCology's inception in 1979, they have used only the purest, and whenever possible, the lowest allergy potential natural ingredients. And while many of the nutrients in their formulas are synthesized from natural plant substances, which as a whole may contain antigens, the synthesizing process removes the molecules of the desired nutrient from the original substance, and in the processing, a great percentage of the antigens and allergens are left behind. The final material then has extremely low allergy potential. This is not to say that no one will react to any of their hypoallergenic formulas, as some extremely sensitive people may. However, the potential for an allergic reaction is low, and the feedback from many of their extremely allergic and sensitive customers is that NutriCology supplements are often the only products they are able to tolerate.
The FDA requires manufacturers to identify the presence of eight major food allergens on all product labels: milk, egg, fish, Crustacean shellfish, tree nuts, peanuts, wheat, and soybeans, as well as any ingredient derived from those foods. When an ingredient may have been derived from a common allergen, they are required by law to list that allergen on the label as a source of the ingredient, even if it does not contain any of the actual substance. For example, 100%-pure glucosamine sulfate does not contain any actual shellfish, but they are required to indicate the source material (shrimp, crab, lobster) on the label. NutriCology fully discloses all ingredients, both active and inactive on every product label, so doctors can make fully informed choices for their patients’ nutritional support.
The following is a list of inactive ingredients used in some of NutriCology's products. These are fillers and excipients as defined by the Food Chemical Codex, nutrient compounds utilized for their physical properties to aid in the supplement production process. Derived from edible sources, they are generally free of common allergens. To determine which natural inactive ingredients are included in a specific product, please refer to the supplement facts panel.
