Starting in 2001, the Chinese pharmaceutical and vitamin manufacturers invested heavily to remodel their production facilities. All of our original manufacturers have passed the ISO 9002 quality certification. Some of our manufacturers just gained GMP certification and the rest are applying for the GMP. This demonstrates the great advancement of the Chinese vitamin production and further assures customers all over the world the top quality products we can offer.

Ascorbic Acid and Related Products:

Weisheng Pharmaceutical (Shijiazhuang) Co., Ltd. is one of the largest ascorbic acid manufacturers in China with annual production of about 12,000 metric tons. Compared to other vitamin C producers in China, their manufacturing facilities are relatively new and they can produce broader range of ascorbic acid products. In 1999, they passed the ISO 9002 quality system certification and in 2001 they became the first vitamin manufacturer to be GMP certified. With growing numbers of so-called “core” customers switching from the Western produced ascorbic acid to the Chinese one, Weisheng is the best candidate that can meet even the highest standards of the pharmaceutical companies.
