Producer
Zhejiang Medicine Co., Ltd.
Zhejiang Medicine Co., Ltd. (Shaoxing, Zhejiang China; SZSE: 000989) is China's largest Vitamin E manufacturer (world's #2) and a major producer of steroid hormone KSMs used in pharmaceutical synthesis. Zhejiang Medicine's steroid intermediate products (including diosgenin-derived pregnenolone, progesterone, and dehydroepiandrosterone) are upstream KSMs for corticosteroids (prednisone, dexamethasone, triamcinolone) — the anti-inflammatory drugs used across rheumatoid arthritis, asthma, COVID-19 treatment, transplant rejection, and oncology. Zhejiang Medicine also produces Vitamin A, Vitamin D3, and carotenoids — key nutritional KSMs for pharmaceutical and food supplement applications. The company represents the dual nature of Chinese pharmaceutical precursor dominance: food supplement vitamins and pharmaceutical steroids made in the same Zhejiang province chemical industrial base.

Did you know2024
Zhejiang Medicine occupies a simultaneous position in two supply chains that most consumers and supply chain analysts treat as entirely separate: (1) the dietary supplement/nutrition market — Zhejiang Medicine's Vitamin E is in health supplements sold at GNC and Costco, animal feed supplements that improve animal welfare, and food preservation antioxidants; and (2) the pharmaceutical corticosteroid supply chain — Zhejiang Medicine's steroid intermediates (diosgenin, pregnenolone, DHEA) are upstream KSMs for prednisone, dexamethasone, triamcinolone, and other corticosteroids used to treat asthma, rheumatoid arthritis, COVID-19 cytokine storm, and organ transplant rejection. The company that makes the Vitamin E in a consumer multivitamin bottle also makes the intermediate for the dexamethasone injected into COVID-19 ICU patients. Chinese pharmaceutical chemistry sits at the intersection of consumer nutrition and life-critical pharmaceuticals through the same Shaoxing manufacturing base.
Zhejiang Medicine Co., Ltd. ↗Origin2023
Zhejiang Medicine was established in Shaoxing, Zhejiang Province — a city known historically for rice wine (Shaoxing yellow wine, the famous Huadiao variety) and industrial heritage that combined fermentation expertise with chemical production. The company built on Zhejiang Province's pharmaceutical chemicals cluster, which developed in the reform era as China's coastal provinces attracted industrial investment. Zhejiang Medicine's Vitamin E business benefited from China's access to natural Vitamin E feedstocks (soybean oil deodorizer distillate, from which d-alpha tocopherol is concentrated) and from cheap chemical synthesis capabilities for synthetic Vitamin E. The steroid intermediate business draws on Dioscorea (wild yam) root saponin chemistry — diosgenin extracted from wild yam tubers is the primary biosynthetic starting material for corticosteroid synthesis, and Yunnan/Guizhou Province's yam agriculture provides the raw material.
