Our bodies manufacture Vitamin D3 when the skin is exposed to UV radiation from sunlight, but the ability to do so decreases as we age. Vitamin D3 (cholecalciferol) is a nutrient that is critical to many bodily functions. It's converted from food sources and sunlight into its active form, calcitriol, by the liver and kidneys. Vitamin D3 is beneficial for supporting bone health, immune wellness, cardiovascular function, and cellular metabolism, among others.

Vitamin D3 helps regulate and control the metabolism of Calcium and Phosphorus by aiding in the absorption of these two minerals from the small intestine, and by directly affecting the rate at which these minerals form and maintain bone. Calcium, the main structural element in bones and teeth, can only be absorbed by the body when Vitamin D is present. It is therefore essential for building and maintaining healthy bones and teeth.

It's estimated that a significant percentage of adults suffer from Vitamin D deficiency which is associated with a variety of health complications. The elderly, alcoholics and strict vegetarians are particularly at risk for deficiency and should consider regular supplementation. Individuals with darker skin pigments may also be at increased risk, as darker skin contains higher levels of melanin, which may inhibit the skin's ability to produce Vitamin D from sunlight.

There is a lot of evidence that people are very deficient in Vitamin D and to get enough a higher dosage is preferable. Also people generally get sicker in the winter when Vitamin D levels are the lowest.
