Enteric coated multiparticulate compositions that use 5-HTP as an active ingredient are disclosed. The multiparticulates have a spheroidal core comprising 5-HTP, microcrystalline cellulose, and hydroxypropyl methylcellulose a sub-coat comprising hydroxypropyl methylcellulose on the spheroidal core and an enteric coat on the sub-coated spheroidal core. The average diameter of the particulates is about 0.1-3 mm. Other aspects of the invention include methods of making and methods of using the multiparticulate compositions.
