Best Supplement for Sleep?
Question: I read tryptophan is now available as a dietary supplement. Is it helpful and safe for sleep issues? If so what dosage would you suggest?

Answer:(published 3/5/10) L-tryptophan, an amino acid, is the metabolic precursor of serotonin, one of the neurotransmitters used by the brain to carry information from one part of the nervous system to another. Serotonin has general sedative effects. In theory, raising the level of L-tryptophan in the brain will cause increased production of serotonin and natural sedation.
L-tryptophan supplements were once popular as sleep aids, but in 1991 the FDA banned their sale in the United States after a contaminated batch from a Japanese manufacturer was linked to at least 37 deaths from eosinophilia myalgia syndrome, a rare and painful disease.
