VITAMIN D IS A LONG TERM INVESTMENT



 Vitamin D is fat-soluble, meaning it is absorbed by fat is essential in resorption calcium and phosphorus from the intestine, also catalysing the transformation of organic phosphorus in inorganic and mobilizing it in the tissues. 
Calciferol component of vitamin D can be classified into vitamin D2 or ergocalciferol and cholecalciferol or vitamin D3
Vitamin D has a dominant role in shaping our skeleton, especially in the growth phase, ensuring the transport of calcium and phosphorus in body areas that need them to support infant growth and remineralization bone adult, allowing the absorption of these minerals in the gut, then transport of phosphorus rebsorption of calcium in the blood and kidneys. The recommended daily dose is 1000 mg deficiency causing rickets in children and osteomalacia in adults. In contrast to other vitamin, vitamin D can be produced by the body.

 The synthesis of vitamin D in the skin is triggered by the existence of ultraviolet rays being absorbed by the blood vessels soon. So the first source of vitamin D is natural sunlight. In case of poor sun exposure should provide resources the body through diet.

 Vitamin D is contained in fatty fish (herring, sardines, tuna, mackerel, salmon) and fish oil (cod, tuna, turbot), egg yolks, butter, whole milk and-milk. Vegetables do not contain this vitamin.

Major biological function of vitamin D is to maintain normality calcium and phosphorus levels in the blood. Vitamin D helps calcium absorption in the body and contribute to building and maintaining bone strength.

 Vitamin D can be used in combination with calcium to increase bone mineral density and reduce the risk of fractures. Recent studies suggest that vitamin D may provide protection against osteoporosis, hypertension, cancer and against several autoimmune diseases.
