[ About Vitamin ]
Vitamin C (Ascorbic Acid) is an essential nutrient for maintenance, growth, repro-duction and health. Long-term lack of Vitamin C will lead to scurvy. For humans, the main symptoms are gum swelling, slow wound healing, bone deformation, hy-pogenesis, and reducing immunity. As to animals, they are body abnormality, in-side hemorrhage, anorexia, sleeping a lot, reducing immunity, and finally influenc-ing the growth of animals.
Humans, especially aquatic species, need supplementing Vitamin C from outside sources, because they are incapable of synthesizing Vitamin C. Lower dosage addition of Vitamin C can prevent and treat scurvy. Its higher dosage supplementa-tion can improve animals' resistance to illness, environmental and physical stress.

[Basic efficacy of Vitamin]
-Involving in the transmitting of hydrogen and electron in the reaction of oxidation and deoxidation;
-Participating the synthesis of colloidal protein and meat alkali;
-Enhancing the absorbing of iron;
-Cooperative action with Vitamin E and alleviating over oxidation of fat;
-Protecting the activity of radicel enzyme;
-Cleaning the threat of free oxygen radicel;
-Enhancing the body immunity.

[Supplementing Vitamin C ]
The research and manufacturing of stable Vitamin C is the effective solution to the supplementation of Vitamin C. The chemical structure of Vitamin C (Ascorbic Acid) leads to high instability, and is easy to be destroyed by various factors such as mental, light, heat, humidity and high pressure, and release the atom of hydro-gen. Crystal Vitamin C is fairly stable in a dry condition, but is easy to be oxidized and decomposed in solution or a base environment.
The most distinct feature of Vitamin C molecule is the strong deoxidization, and easy to react with some mental ion (especially Cu, Co, Mu, Zn and Fe). Vitamin C is the most unstable among various vitamin additives for aquatic feeds.
