Try it yourself and see.
Get some vitamin D.
don’t take the recommended daily amount (RDA) take 10 times that amount for a week straight.
You will notice a difference. You may feel better than you have in years. You could take an entire bottle and it wouldn’t hurt you.
Get some magnesium too! important or else you might get muscle cramps.
I’ve been taking 5000 to 7000 IU of D3 for several months and was taking 3000 IU before that.
so you are suggesting taking 60000 iu's? and no downside?
