Vitamin D is a fat-soluble vitamin that is naturally present in very few foods and added to others through fortification. Vitamin D is also produced within the cell when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis.3 The skin synthesis is reduced by clothing, sunscreen, air pollution, older age, darker skin pigmentation, being indoors, winter season, and higher latitude.

Unfortunately, too many Americans are not getting enough of this important nutrient so supplementation is often recommended. Vitamin D supplements are available in two forms. Vitamin D2, or ergocalciferol, is plant-derived, while vitamin D3, cholecalciferol, is animal-derived. Vitamin D3 is more effective than vitamin D2 at raising and maintaining adequate levels of circulating vitamin D in the body.2†

The 2015 USDA Dietary Guidelines for Americans Committee identified vitamin D as a “nutrient of public health concern, as 9 out of 10 Americans fail to meet their daily vitamin D needs.1"

It is common for many healthcare providers to recommend 25-50 mcg (1,000-2,000 IU) of vitamin D per day for general health.9 A primary healthcare provider can perform a simple blood test to assess serum 25-hydroxyvitamin D levels. This test can determine your vitamin D status and subsequently recommend a vitamin D supplement regimen to help you achieve and maintain healthy serum vitamin D levels.

The recommended intake for vitamin D varies throughout your life to maintain bone health. For infants (0-1 year) it is 10 mcg (400 IU) per day. For Children & adolescents (1-18 years) it is 15 mcg (600 IU) per day. For Adults (19+ years) it is 15-20 mcg (600-800IU) per day.3

Very few foods are natural sources of vitamin D. Fatty fish (mackerel, salmon, sardines) and fish liver oil are among the best sources of vitamin D10.

Vitamin D may also be consumed through fortified foods. Vitamin D fortification of certain dairy products and cereals began in the early 20th century to help eradicate disease such as rickets. Consequently, some cow milks, cow milk substitutes, infant formula, orange juices, breads and cereals may add vitamin D added to support adequate intake of vitamin D.
