Source Naturals L-Tryptophan with Coenzyme B-6 500 mg - 30 Tablets

For those seeking a gentle, non-habit-forming approach to winding down at night, L-Tryptophan provides a natural solution. This essential amino acid plays a vital role in the production of serotonin and melatonin, neurotransmitters that help regulate mood and the sleep-wake cycle. Source Naturals L-Tryptophan with Coenzyme B-6 is formulated to support your body's own rhythms.

Key Ingredients and How They Work

L-Tryptophan is an essential amino acid that your body converts into 5-HTP, then into serotonin, and finally into melatonin. Serotonin helps maintain a positive mood, while melatonin supports a healthy sleep cycle. The inclusion of Coenzyme B-6 (pyridoxal-5-phosphate) is key—it acts as a cofactor in these enzymatic reactions, ensuring optimal conversion. Each tablet delivers 500 mg of L-Tryptophan, a dose used in clinical studies. Unlike synthetic sleep aids, this formula works in harmony with your body's natural processes.
