My last Vitamin D was 34 ng/mL, and I aim for 30 - 40 ng/mL.

If I may ask, what daily dosage maintains you at that level?

Also, I had a doctor prescribe D2, while most supplements are D3. Any thoughts?

Thanks!

D3 is best, unless your doctor said you has some reason for D2. You could call to confirm.

My daily average from supplements is 2,850 IUs. Outdoor time and foods or drinks can add to that.

With Vitamin D, I take a D3 5,000 IU gelcap every other day.

Vitamin D averages out in the blood over weeks, so you don't need it every day, like B-vitamins.

Hope that helps!

D2 is from a vegetable source and needs to be converted to D3. D3 is better as it is far more available to the body immediately as it doesn’t need to be converted. D2 is generally considered inferior, which is why it’s scarce. Apparently, it’s the preferred for for die hard vegans.

Sunlight is the best source. Diet is next, then supplements.

Fire your doctor.

D2 lasts less.

D3 is human vitamin d. D2 is mushroom’s vitamin d. If aliens turn you into a mushroom, take D2.
