    Source Naturals - L-Tryptophan with Coenzyme B-6 500 mg - 120 Tablets

    Source Naturals L-Tryptophan with Coenzyme B-6 helps support relaxation, restful sleep, and a positive outlook.  It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. This tryptophan includes the activated coenzyme form of vitamin B-6, called P-5-P, that is required to convert tryptophan to serotonin. L-Tryptophan also supports immune functions because it is the body's precursor to the kynurenines that regulate immunity. If needed, L-tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system. Source Naturals L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.

    Feeling Good—It Isn’t All in Your Head
    Today’s nutrient-deficient diets certainly affect your body, but did you realize that they affect your mood and brain chemistry as well?
    Diets that are heavy in refined grains, sugars, and saturated fats frequently can lead to a deficiency of one of the most fascinating
    amino acids in the body: L-tryptophan. Diets lacking this important amino acid lead to imbalances that affect mood, ability to sleep,
    and ability to handle stress. L-tryptophan is also the body’s natural aid after too much exercise or occasional monthly discomforts in
    women, and it helps the body make the transition to new time zones after long flights. Yet even with these important roles, L-tryptophan
    is lacking in many people because it is the least abundant amino acid in the diet.  

    Amino Spark
    L-tryptophan is the spark that ignites the body’s production of 5-HTP and from that, serotonin, a neurotransmitter that controls sleep, memory, learning, the body’s temperature, mood, behavior, many sexual responses, cardiovascular functions, and endocrine regulation. L-TRYPTOPHAN is the best alternative for relaxation and improved mood. With the addition of coenzyme B-6, L-TRYPTOPHAN WITH B-6 is the precursor of melatonin, another amazing neurohormone that controls biological rhythms, sexual organ development, pigment metabolism, immune response, metabolism of free radicals, mood, sleep, and cellular differentiation. It is a primary building block of a healthy body. This is the best alternative if you are interested in deep, healthy sleep. 

    L-tryptophan or 5-HTP?
    Even though L-tryptophan and 5-HTP are converted to serotonin, widely known as the body’s mood and sleep regulator, there are differences in the two. First is that L-tryptophan is an important amino acid that has many functions in the body—for example, it can be
    converted to niacin, or to the precursor to the kynurenines, a family of biochemicals that help regulate the immune system, if that is
    what the body needs. These multiple functions cannot be done by 5-HTP. Another difference is that all 5-HTP is converted to serotonin. The body regulates the amount of Ltryptophan that is converted to serotonin based upon the body’s needs.

    Wellness Revolution
    L-tryptophan is an essential amino acid; it is not synthesized by the body, so you must obtain it through diet or supplements. Eat a diet that includes plenty of complex carbohydrates, raw fruits and vegetables, soybeans and soy products, whole grains, seeds, nuts, brown rice, millet, and legumes. It is recommended to avoid alcohol, caffeine, and processed foods and to get plenty of exercise. Supplementing a
    healthy diet with Source Naturals L-TRYPTOPHAN and L-TRYPTOPHAN WITH B-6 are excellent means of ensuring that you have the
    required amount of this important amino acid, for a healthy body, for restful sleep, and…to just feel good.

    1 tablet three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 tablets before bed.

    About Source Naturals

    Leaders of the Wellness Revolution
    Source Naturals was created in 1982 by C.E.O Ira Goldberg to support each individual's potential to enjoy optimal health. At that time, the kind of nutritional formulations he envisioned – for the maintenance of well-being and the enhancement of life – simply didn't exist. The idea of combining many nutrients, herbs, and nutraceuticals in one formulation, though common today, was then a rarity. Source Naturals pioneered the concept with Wellness Formula, now the industry's #1 immune support product.

    Source Naturals subsequently introduced numerous award-winning formulas, recognized for their excellence in independent surveys and nutritional analyses. In addition to Wellness, these award-winners include Life Force Multiple, Mega-Kid Multiple, Inflama-Rest, the Skin Eternal line, Higher Mind, Essential Enzymes, Male Response, and more.

    Source Naturals' comprehensive Bio-Aligned Formulas help bring the power of alignment to your body. When formulating, they evaluate the underlying causes of system imbalances, and then provide targeted nutrition to interdependent body systems. Their line of more than 600 products also includes well-researched, single entity nutrients in their highest quality and most bioavailable forms.

    Source Naturals' nutritional supplements are at the leading edge of today's Wellness Revolution. This transformation in health consciousness also includes new perspectives in diet, lifestyle, emotional, and spiritual development, and complementary health care. Source Naturals Strategy for Wellness is to provide education that empowers individuals to take responsibility for their health, rather than relying solely on outside medical authority. The result is people who are more productive and fulfilled, and a world that is stronger and healthier.

    Works, but slight "hangover"effect. Not serious enough to warrant discontinuing use, as I quickly overcome the "hangover", within half an hour after awakening. Inasmuch as many other products of similar content fail, this one remains a necessary sleep aid for my serious insomnia problem.
