Difference between Vitamin D and Vitamin D3?

Vitamin D can be found in 2 forms: D2 or D3. Vitamin D2 is produced by plants. You would consume it through fortified foods such as juices, milk or cereals. However, vitamin D3 is formed when the body synthesizes sunlight. It mainly occurs through the exposure of the skin to UVA and UVB rays. Vitamin D3 can also be obtained by consuming animal products and can be found in lamb’s wool. Vitamin D3 is more difficult to find in everyday foods and more sought out in a pill form (or liquid for babies). Therefore, Vitamin D3 is most likely what was in the D 'Vi' Sol Supplement.

Vitamin D could be either Vitamin D-2 or Vitamin D-3. Vitamin D-3 is usually made from lanolin, a substance extracted from sheep's wool. However there are many vegans out there which brought about the need for D-2 supplements. Vitamin D-2 is completely vegan but is a little less potent than D-3. However they both have the same effect, with D-2 you just need to take more of it. Since it just says Vitamin D it is probably D-3 however, unless it states that it's vegan, because D-3 is much cheaper to make.
