FAQ:

Q: What are the best tryptophan supplements?

A: Longlifenutri has a pretty basic tryptophan supplement with the standard 500 mg dose per capsule. The bottle is fairly generous, with 120 capsules included, and the design is clean: the gelatin capsules contain only L-tryptophan and magnesium stearate. Without much to complain about, this is a good solid pick.

Q: What is tryptophan?

A: Tryptophan is an essential metabolic component of the human diet for a range of bodily functions. It is one of ten essential amino acids, meaning the body does not have the ability to synthesize it. Tryptophan must be acquired by outside sources, namely dietary intake.

Q: How many mg of tryptophan are in a bottle?

A: The capsules are cellulose-based, have 500 mg of tryptophan each, and come in a fairly ample amount per bottle (120 caps, to be specific). Though Superior Labs is a smaller brand, this supplement still has a wide base of support among tryptophan supplement users.

Q: Is tryptophan safe to take?

A: Some researchers, such as D.M. Richard and colleagues at the University of Texas Health Science Center, argue that tryptophan is safe when used at clinical doses, pointing to a large body of clinical literature demonstrating the safety and efficacy of this supplement ( 6 ).
