Plain 100 mg 5-HTP with nothing else added, in a 90-capsule bottle that covers three months at one a day. This is the reference point on this site whenever a dose is discussed without a cofactor or a delivery gimmick attached.
50 mg sits at the low end of the commercial range, which makes this the practical bottle for starting cautiously or splitting a daily amount across the day. Ninety capsules at one a day runs three months.
Enteric coating is the differentiator: the capsule is built to stay closed until it is past the stomach. That is the reason people reach for this one, since stomach upset is the complaint that most often ends a 5-HTP trial.
Pairs 5-HTP with both B6 and vitamin C. The listing does not state the 5-HTP milligram amount, so read the panel rather than assuming it matches the 100 mg bottles here.
Suntheanine is the branded form of L-theanine, so the isomer content is specified rather than left open. Still a theanine product rather than a 5-HTP one.
A second 500 mg tryptophan bottle for the same upstream comparison. Same caveat: this is the precursor to 5-HTP rather than an alternative dose of it.
