Research has suggested that we may need much more vitamin D than previously thought for optimum immune support and long-term health.* Cholecalciferol, also known as Vitamin D3, is more biologically active in the body than vitamin D2.* In some climates people may get adequate vitamin D3 from sunlight, but in cooler climates at higher latitudes, with longer winters, vitamin D deficiency may occur with greater frequency.*

The amount of vitamin D3 that an individual needs varies due to a variety of factors, but for many individuals vitamin D intake may not be enough to provide complete health benefits.* Some factors that contribute to vitamin D deficiency include:

Spending most of the day indoors.

Using sunscreen.

Wintertime & less sunny climates.

Darker skin tone (melanin blocks UVB rays, which facilitate vitamin D production in the skin).
