Label statements

Directions: Suggested usage: Take 1 tablet 1 to 2 times daily on an empty stomach, with final dose at bedtime, or as directed by your healthcare practitioner.

Formula: Contains: How it works: Tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained from the diet. In the brain, tryptophan is converted into serotonin, a neurotransmitter involved in feelings of well-being, calmness, personal security, and relaxation. It also plays a role in the regulation of appetite and synchronization of sleep patterns.

Precautions: All Other: Cautions/interactions: Tryptophan supplements may interact with CNS depressants, antidepressants (SSRIs, MAOIs), and other serotonergic agents such as St. John's Wort and 5-HTP. May cause drowsiness. Do not use with alcoholic beverages or while operating heavy machinery.
