Label Statements
FDA Statement of Identity: Dietary Supplement
Seals/Symbols: Tamper-evident seal
Product Specific Information: 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. Source Naturals L-TRYPTOPHAN is extremely pure and is regularly tested to ensure the highest standards of quality.*
Suggested/Recommended/Usage/Directions: Suggested Use: 1 tablet three times daily, between meals and preferably with fruit juice. To support restful sleep, take an additional 3 tablets before bed.
Precautions re: All Other: CAUTION: If you are pregnant, may become pregnant, breastfeeding, or are taking medications such as SSRIs or MAOIs consult your health care professional before using this product. STORE IN A COOL, DRY PLACE. Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.
