Crystalline Pharmaceutical Vitamin C Raw Materials for Improving Metabolism
The appearance of Vitamin C is white crystal with faintly acid. It is the most important soluble vitamin in the body of human beings. Most of the mammals can compound vitamin C in their body. But human beings can not do that and must beobtained from diet or supplementation. In the body of human being, Vitamin C has many functions like anti-oxidation, anti-inflammatory, antiviral, anti-microbico, production of collagen. All these functions are the basic conditions for keeping healthy.
