Vitamin D3 / Cholecalciferol

TIANJIN ENJU BIOTECHNOLOGY CO., LTD. operates as a broad-catalog supplier spanning nutraceutical and biochemical actives (S-Adenosyl-L-methionine, pyrroloquinoline quinone, magnesium L-threonate, L-glutathione, L-carnitine, coenzyme Q10, alpha lipoic acid), a wide range of generic human APIs across antidiabetic (sitagliptin, empagliflozin, dapagliflozin, semaglutide, liraglutide), cardiovascular, anti-infective, and CNS categories, veterinary and feed-grade antibiotics, vitamins, and plant extracts, and a further line of steroid and hormone-class ingredients. Given the sheer breadth of its catalog, the company functions as a wide-line source of pharmaceutical, veterinary, and nutraceutical raw materials rather than a single-focus manufacturer.
