Why Supplement with Vitamin D?


Vitamin D is considered a nutrient of public health concern. This is because many Americans are not getting enough Vitamin D in their diets and low intakes can affect overall health. As many as 96% of Americans do not get enough Vitamin D from food alone.1


This is partly because natural food sources of Vitamin D are limited and not always appealing. They include cod liver oil, liver and some types of fatty fish such as mackerel, salmon, and sardines. In the US, milk but not all dairy products, is fortified with Vitamin D. It is important to check the label on products like cheese and yogurt to see if they were made with fortified milk.

Vitamin D

Get To Know Immune Support

Vitamin D is a fat-soluble vitamin that can be obtained through the diet or synthesized in the skin upon exposure to sunlight. Vitamin D3, the form of vitamin D formed in the skin, is a potent and active form of the vitamin. Vitamin D2 is a vitamin D analog formed in plants, mushrooms and yeasts during photosynthesis. While vitamin D2 is sometimes used in food fortification, Puritan’s Pride® supplements provide the active form.
