Source Naturals Nervous System Support - L-Tryptophan 1000 mg with

Mood‚ Relaxation‚ Sleep!The essential amino acid L-tryptophan 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.
