... what the differences are between Pro-D3 20,000 and Bio-Vitamin D3 20,000?
Most likely, absolutely nothing. Presumably some form of International Unit e.g. 20,000IU but that would be 20 times the recommended supplementary dose per day which is normally 1000IU or 25 mcg (micrograms). This can be increased to 2000IU or 50 mcg/day in women who are thinking of becoming pregnant, in the first trimester especially and also breastfeeding (I think).
For older women with osteopenia or osteoporosis there is a combination Calcium/Vitamin D supplement also. The recommended dose will be on the container.
There is a lot of debate about how much Vitamin D is too much per day. I take 25 mcg/day as recommended by my Endocrinologist. Some people take 20 times that much; I don't know why, but, then, I haven't investigated either.
