5-히드록시트립토판 (5-hydroxytryptophan) 은 미국 티에스아이사(몬태나주 소재) 를 필두로 최근 Bilberry Extract, Ginkgo Biloba 제품 등을 판매하는 미국의 리니아사 등이 소재 시장을 주도하고 있으며, 완제품의 경우 줄 미국 시장을 중심으로 수백여 종 이상의 각종 건강기능식품 제형이 시장에 출시되어 있다. 대표적인 제형들을 소개한다.

HCA 지표의 가르시니아 캄보지아보다 우수한 식용 억제 효과와 Vinpocetine, Valerian 그리고 세인트 존스 워트 등을 능가하는 우울증 개선 효과 등을 무기로 한 5-HTP 의 미국 지역 이외의 향방에 귀추가 주목되고 있다.
