Source Naturals L-Tryptophan 500 mg.

Source Naturals L-Tryptophan promotes mood, relaxation, and sleep. The essential amino acid Source Naturals L-Tryptophan helps support relaxation, restful sleep, and feeling better. Source Naturals L-Tryptophan plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. Source Naturals L-Tryptophan also supports immune functions because it is the body's precursor to the kynurenines that regulate immunity. If needed, Source Naturals 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.

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, Source Naturals evaluates the underlying causes of system imbalances, and then provides targeted nutrition to interdependent body systems. Source Naturals' 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.
