Beta carotene of this tablet is converted to vitamin A (Retinol) when required. Retinol has several biochemical functions e.g. on retina, growth, tissue differentiation, immunological response. It has also some anti-cancer activity.

Vitamin C is the most powerful reducing agent known to be present in living tissues. Vitamin C deficiency produces scurvy. It is a cofactor in numerous biological processes. Vitamin C and molecular oxygen are essential for the conversion of proline to hydroxyproline, dopamine to noradrenaline . Vitamin C is also essential for the synthesis of adrenal steroid hormones. Vitamin C is important in the defense against infection and studies shown that vitamin C is important for the normal functioning of T-lymphocyte and leukocyte. Ascorbic acid has some antiinflammatory activity and protects cells against oxidation of essential molecules. In high doses, (1-2 g daily) ascorbic acid increases iron absorption.

vitamin E seems to be as a defense against oxidative stress and lipid peroxidation. In most cell membranes there is one molecule of tocopherol for every 1000 lipid molecules. Tocopherol mops up peroxide radicals and then needs a supply of reduced hydrogen to restore the steady-state situation. This is usually supplied by ascorbic acid or reduced glutathione.

This is the preparation of Calcium Carbonate and Vitamin D3 (Cholecalciferol). Calcium is necessary for many normal functions of our body, especially bone formation and maintenance. Vitamin D3 helps for the absorption & reabsorption of Calcium. Vitamin D3 also stimulates bone formation. Clinical studies showed that Calcium and Vitamin D3 all together helps in bone growth, and in prevention of osteoporosis & bone fracture.
