Benefits of Vitamin D

What is vitamin d? Vitamin D is a fat soluble family of compounds known as vitamins D1, D2 and D3.

The biologically active form of vitamin D is a hormone known as calcitriol.

• Bone - The most important functions of vitamin D are to regulate the absorption and use of calcium and phosphorus which are vital for normal growth and development of bones and teeth.

  Vitamin D stimulates intestinal absorption and reabsorption in the kidneys as well as maintaining blood levels of calcium and phosphorus.

  It enables bones and teeth to harden by increasing the deposition of calcium and may also assist in the movement of calcium across body cell membranes.

• Immune System - Vitamin D may also be involved in immune system regulation and play a part in the prevention and treatment of infectious diseases.

  Parts of the bone marrow which produce immune cells are receptive to vitamin D.

• Fertility - Vitamin D is essential for strong pelvic bones and therefore plays an indirect role in fertility.
• Hormones - Vitamin D plays a role in the secretion of insulin by the pancreas thus aiding in the regulation of blood sugar.

  It also affects the parathyroid gland and a hormone that it produces due to its calcium regulating role.

• Nervous System - Vitamin D ensures the functioning of healthy nerves and muscles by regulating the level of calcium in the blood.

  Calcium is vital for normal nerve impulse transmission and muscle contraction.

• Bone health. Vitamin D is recommended to support bone health in postmenopausal women.
• Psoriasis. Vitamin D may also be of benefit in the control of psoriasis.
