When tryptophan is ingested as a food or supplement, it is naturally degraded by specialized enzymes in the body. The problem is activity of one of these enzymes increases with age thereby denying the brain the tryptophan it needs to produce adequate serotonin. The result of the excess degradation of tryptophan can be seen in serotonin-associated troubles, such as:
The TryptoPure® L-Tryptophan formula contains tryptophan that is certified pure enough to be used as an active ingredient in pharmaceutical products. This pharmaceutical-grade L-tryptophan costs more than other tryptophan raw material as it undergoes significantly more rigorous manufacturing processes to safeguard purity.

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. Do not use before driving or operating heavy machinery.
