Rebel Performance L-Tryptophan is a dietary supplement that supports healthy mood, zen-like relaxation, and deep, restful sleep by directly promoting the synthesis of both melatonin and serotonin in your body. L-Tryptophan also supports key immune functions because it is the body's precursor to the kynurenines that regulate immunity. Rebel Performance L-Tryptophan is very pure and is tested to guarantee the highest levels of quality.
