Vitamin C Injection

Ascorbic acid, a water-soluble vitamin, is essential for formation of collagen and intercellular material, therefore necessary for the development of cartilage, bone, teeth and for the healing of wounds. It is also essential for the conversion from folic acid to folinic acid, facilitates iron absorption from the gastro-intestinal tract and influences haemoglobin formation and erythrocyte maturation.
