L Tryptophan is an essential amino acid important in human nutrition for the synthesis of melatonin and serotonin, hormones regulating mood and stress response.* L-Tryptophan helps support relaxation, sleep, disposition and immune function.* As an essential amino acid, it is not synthesized by the body and must be obtained from the diet. 

NOTE: **We typically recommend you try 5HTP first instead of L Tryptophan - unlike L Tryptophan, 5HTP moves easily into the brain and does not compete with other amino acids for passage.**


As a dietary supplement, take 1-2 Vcaps® daily, preferably at bedtime. For intensive use, take up to 6 Vcaps® daily, in divided doses, as directed by a health care practitioner.

Store in a cool, dry place. Keep out of reach of children. Pregnant/lactating women, those taking anti-depressant medications (such as SSRI's or MAOI's), or those with liver disorders, consult a health care professional before using this product. May cause drowsiness.

A frequent side effect from high dose Tryptophan use is drowsiness; it is advisable to take L-Tryptophan in the evening and not while driving or operating heavy machinery. Dry mouth and gastrointestinal upset are among the small number of relatively uncommon side effects.*

Tryptophan should not be used concomitantly with monoamine oxidase inhibitors/selective serotonin reuptake inhibitors (SSRIs). Individuals with liver cirrhosis should avoid tryptophan supplementation.
