Life Extension, TryptoPure L-Tryptophan, 500 mg, 90 Veggie Caps

Read the entire label and follow the directions carefully prior to use.

Take one (1) capsule 1-3 times daily or as recommended by a healthcare practitioner. For maximum absorption, take with 6-8 oz. of water or a small amount of carbohydrate such as diluted juice. Take separately from food or supplements containing protein or amino acids. Vitamin B6 is an essential cofactor in the conversion of L-tryptophan to serotonin in the body, while niacinamide plays an important role in enabling the body to properly utilize amino acids like tryptophan. Therefore, those taking L-tryptophan may find optimal results by consuming a B-complex supplement during the day that provides at least 50 mg of niacinamide and 50 mg of vitamin B6.

Serotonin syndrome is characterized by high levels of serotonin and symptoms like confusion, sweating, agitation, nausea, involuntary muscle contractions and racing heartbeat. Do not take L-tryptophan if you experience these symptoms. Do not take L-tryptophan in combination with other agents that increase serotonin levels in the central nervous system. Agents that increase serotonin levels can include psychiatric medications (e.g. antidepressants, lithium), migraine medications (e.g. sumatriptan), Parkinson's disease medications (e.g. carbidopa) and dextromethorphan, an over-the counter cough suppressant.
