Vitamin D3 is found in a number of foods. Good food sources are: oily fish – such as salmon, sardines, herring and mackerel, red meat, liver, egg yolks and fortified foods such as most fat spreads and some breakfast cereals.
We need vitamin D to help the body absorb calcium and phosphate from our diet. These minerals are important for healthy bones, teeth and muscles.
A lack of this vitamin – known as vitamin D deficiency – can cause bones to become soft and weak, which can lead to bone deformities. In children, for example, it can lead to rickets. In adults, it can lead to osteomalacia, which causes bone pain and tenderness.
Vitamin D is a fat-soluble vitamin which can either be ingested in food or manufactured by the body as a result of sunlight falling on the skin.
People who feel they do not get enough sunshine often choose to supplement it in their diet.
This vitamin is vital for the proper absorption of calcium and the use of phosphorus to form healthy bones and teeth.
It has other roles in human health, including modulation of neuromuscular and immune function and reduction of inflammation. Many genes encoding proteins that regulate cell proliferation, differentiation, and apoptosis are modulated in part by vitamin D.
In various studies, Vitamin D3 has been shown to have the following properties;
*Reverse some cases of hearing loss
*Help treat migraine in conjunction with calcium
*Improve bone density in osteoporosis
