Vitamin D at Lowest Prices

What forms are available?

There are actually 2 forms of vitamin D; D-2; and D-3;. Vitamin D-2; (ergocalciferol) can be found in supplements and comes from plant and/or fungal sources that are irradiated. D-2; however is not as efficiently used as D-3;.  D-3; (cholecalciferol) is naturally occurring in our bodies after skin is exposed to direct sunlight/ UV light. It can also be found in vitamin supplements and foods, such as fortified milk, fatty fish, fish liver oil, and egg yolks.  Because D-3; is naturally found in the body it is preferred for supplementation. D-3; supplement is primarily sourced from sheep's lanolin or fish oil, however there are vegan D-3; supplements available.

People at risk for deficiency

Although there is no known cause for a deficiency in vitamin D, there are a few cases that can make you more predisposed to developing it. These cases include being vegan, being limited to sun exposure, if your kidneys cannot convert it to a active form, if you have issues absorbing nutrients, and obesity. If you feel you may be low in vitamin D or present symptom of a deficiency, you can get a blood test to indicate your body's level.
