Is vitamin D-3 the same as vitamin D?

Vitamin D and Vitamin D3?

• Is there a major difference in taking either one? I usually by just Vitamin D but by mistake got D3 -

• Answer:

  You made a very good mistake! Vitamin D3 (also called cholecalciferol) is the good version of vitamin D that you want to take. That is what sunlight produces naturally in our skin. When you see something labeled as merely Vitamin D, it is likely the synthetic version, Vitamin D2 (also called ergocalciferol). Vitamin D2 was the first synthetic form of Vitamin D and is the form of vitamin D in all Vegan Vitamin D. It was used, and still is in many cases, to fortify foods, make some Vitamin D supplements and is the basis for ALL Prescription Vitamin D. Besides being the natural form of Vitamin D, Vitamin D3 is three times more potent than Vitamin D2.
