L-Tryptophan is an essential amino acid therefore, it is not synthesized by the body and must be obtained from the diet. L-Tryptophan is critical for the production of serotonin and melatonin, which help to support a positive mood, healthy sleep patterns, and proper immune system function. Every lot of L-Tryptophan is free of Peak E and microbial contamination.
It’s excellent
With one of these capsules and one 10 mg melatonin, I sleep very well through the night.
