1. Vitamin C magnesium phosphate ester is a derivative of vitamin C, which is processed with modern science and technology using vitamin C as raw material. This product, whether taken orally or absorbed through the skin into the human body, can quickly free vitamin C through phosphatase enzymatic hydrolysis, giving play to the unique physiological and biochemical functions of vitamin C.
2. Vitamin C magnesium phosphate has all the benefits of vitamin C. It also overcomes the disadvantage that vitamin C is afraid of light, heat and metal ions, and is easy to be oxidized.
