Sichuan Neijiang Huixin Pharmaceutical Co., Ltd.

Sichuan Neijiang Huixin Pharmaceutical makes vitamin D2 and concentrates on that single product. Ergocalciferol goes into fortified foods and drinks, nutritional supplements and feed, and the company sells it under the Jinzishan brand, working from a sugarcane-derived plant raw material through a biotechnological refining route rather than from an animal source.

Material is made to the CP, BP, USP, EP and IP monographs, and the company will formulate to a customer's own specification, including diluted and carrier-bound forms. It manufactures at Neijiang in Sichuan, has passed GMP inspection more than once and holds Kosher and Halal certification.
