Are store brand Vitamin D3 supplements just as good as expensive ones?
Just compare the amount of vitamin D3 in both products. I tend to buy store brand for a lot of vitamins, “tylenol”, cold tablets, etc. I just compare what’s in the product. For example the store brand “tylenol” is identical in strength as the expensive brand. I buy the store brand multi-vitamins with minerals rather than Centrum, because they are absolutely identical in all the vitamins and minerals in each tablet. Same with calcium supplements.
