From the manufacturer's website:
L-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.* Every lot of Protocol For Life Balance® L-Tryptophan is tested to be free of Peak E and microbial contamination.
• Encourages Positive Mood*
• Supports Relaxation & Restful Sleep*
Warning: 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*. May interact with monoamine oxidase inhibitors/ selective serotonin reuptake inhibitors (SSRIs). Individuals with liver cirrhosis should avoid tryptophan supplementation. Store in a cool, dry place. Please recycle.
