Vitamin D, a fat-soluble vitamin is needed for proper absorption of calcium & phosphorus. It is necessary for growth especially in children. It is acquired either by ingestion or by exposure to sunlight. Vitamin D known as cholecalciferol, is the natural form as it occurs in fish liver oil. Vitamin D aids in the absorption of calcium from the intestinal tract and the breakdown and assimilation of phosphorous, which is required for bone formation. Vitamin D helps prevent and cure Rickets, a disease resulting from insufficient calcium, phosphorous or vitamin D.Vitamin D is valuable in maintaining a stable nervous system, heart action, and normal blood clotting because all these functions are related to the body's supply and utilization of calcium and phosphorous.
Vitamin D deficiency can result in:
- Nearsightedness
