Overview Vitamin D3 not D2

Vitamin D2 has been known for a long time to not be as good as vitamin D3

VitaminD2 was the first to be discovered and, until 2011, was the only one that most doctors could prescribe
The D3 form has been known for many decades, but the medical profession has not yet adapted - after all, only 20,000 papers on D3 so far.

Several recent studies have shown that vitamin D2 actually reduces the levels of D3 in the blood
AND, worse still, D2 actually INCREASES a health problem, instead of reducing it, the way vitamin D3 does

Hint: if you can buy it, it is Vitamin D3. Vitamin D2 is only available by prescription
Note: some multivitamins and milk/food fortifications still use D2, sut in such low quantities that it can be ignored.
