We find that most users prefer at least 500 mg, with many taking 2-3 capsules a day. However, there are some users that need lower amounts. For this reason we offer a 100 mg tablet and a 220 mg capsule.
Note: Canada also limits what customers can ship to their country, so if you live in Canada please choose L-Tryptophan in 220 mg or less per serving.
