The essential amino acid L-tryptophan helps support relaxation‚ restful sleep‚ and positive mood. It plays a part in the synthesis of both melatonin and serotonin‚ hormones involved with mood and stress response and sleep/wake cycles. 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. Source Naturals L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.

My acupuncturist recommended Source Naturals L-Tryptophan and Theanine Serene with Relora, taken together, to help me fall sleep. I've been using L-Tryptophan 500 mg about a year and they work wonderfully. You never know how exhausted you've become until your sleep is replenished.
