Benefits Of Vitamin D
The benefits of Vitamin D are numerous. Apart from being essential for bone growth, Vitamin D is is a potent immune system modulator, and it plays a role in insulin secretion. There is growing scientific evidence that it also may prevent other diseases. In the video below, Carole Baggerly of Grassroots Health talks about vitamin D and the recommended dosage for protection from a host of diseases such as cancer, diabetes, multiple sclerosis heart attacks and fractures. She talks about the widespread deficiency of vitamin D levels in the general population and how we can dramatically improve out health and obtain the benefits of vitamin D by maintaining our levels of Vitamin D between 40-60ng/ml.
Facts About Vitamin D
Vitamin D is synthesized from sunlight when our bare skin is exposed to it and can also be obtained from diet. However, obtaining a sufficient amount of vitamin D from diet and sunlight can be difficult as there are very few foods that contain vitamin D. Once in the body, Vitamin D is converted to 25OHD. It is this compound that is measured in the blood by your doctor to asses if you have adequate Vitamin D. It is currently thought that between 40 to 75% of the world’s population is deficient in Vitamin D.
Vitamin D Supplements
There are two types of vitamin D supplements available on the market, vitamin D2 (ergocalciferol) and vitamin D3 (calciferol). Generally many nutritionists recommend vitamin D3 as humans synthesize this form of the vitamin in the presence of sunlight. It is the more potent form, and is more stable and less toxic compared to vitamin D2. The benefits of vitamin D are not confined to better individual health, but also extend to overall reduction in health care costs in the world.
