Vitamin D3: It's More Important Than You ThinkVitamin D3, also known as (cholecalciferol), is the most bio-available form of Vitamin D, which is essential for skin, bone and immune health.
Vitamin D3 is far more important to every day health and the prevention of long-term illness than a vast (but rapidly shrinking) majority of people currently understand. In moderation, the sun can be both extremely therapeutic as well as a major force helping to ward off illness. Of course, you don't want to overdo it. As we all know, too much sun exposure can be hazardous to your health and to your skin.
It has long been established that supplementing with Vitamin D3 may help lower blood pressure and cholesterol in patients struggling with high levels of either and/or both.
Vitamin D3 is the single most important vitamin for bone health. It plays a vital role in the synthesis of calcium and magnesium in the bones. A few of the many, many diseases resulting from Vitamin D Deficiency are rickets, osteoporosis and heart disease.
I personally do not supplement with D3 during the summer months when I wear as little as possible when outdoors (I have relatively dark skin for a white guy, and I generally do not burn). However, come winter, Vitamin D3 is a daily staple and a major part of my nutritional supplementation regimen.
