Vitamin D Benefits
|
Vitamin D benefits are mainly known to the general public by their so-called "bone-building" properties and abilities.
Vitamin D refers to a group of fat-soluble vitamins that can be found in food, dietary supplements, and the sun. Vitamin D is also known as calciferol and it has two major forms: Vitamin D2 or ergocalciferol and Vitamin D3 or cholecalciferol. Calcitriol is the active form of vitamin D found in the body. The term vitamin D also refers to these metabolites and other analogues of these substances.
Vitamin D is a prohormone, which is a precursor to a hormone, but usually having minimal hormonal effects by itself. |
 Vitamin D is needed for the maintenance of calcium and phosphorus in the blood, among others. Calcium is essential to the formation and maintenance of strong bones in the body. The recommended daily allowance for Vitamin D is 400 IU per day.
The following are the major dietary sources of Vitamin D:
- fish (such as herring, catfish, salmon, mackerel, sardines)
- eggs
- fortified milk
- cod liver oil
- beef liver
- mushrooms
The classic Vitamin D deficiency diseases are rickets and osteomalacia. Rickets is a disease which results in skeletal deformities. On the other hand, osteomalacia results in muscular weakness and weak bones. The elderly, obese individuals, exclusively breast-fed infants, as well as those who have limited sun exposure, are at a high risk for Vitamin D deficiency diseases.
Those who take too much of the vitamin is in risk for Vitamin D toxicity. Overdose has been observed at 1925 µg/d or 77,000 IU per day. Dehydration, vomiting, irritability, constipation and fatigue are the observed symptoms of Vitamin D poisoning.
The following are the vitamin D benefits that may be derived from this vitamin:
Vitamin D promotes the absorption of calcium and phosphorus to enable and facilitate the mineralization and growth of bone. Vitamin D helps modulate the immune function and helps to protect from autoimmune diseases. Vitamin D helps reduce inflammation. Vitamin D may help protect from osteoporosis. Vitamin D may prove helpful in protecting against certain forms of cancer. Vitamin D may prove helpful in fighting high blood pressure and coronary/cardiovascular diseases. |
