I know that this is a herbalism forum but I'll bet someone here will know the answer to my question about multivitamins. I take one every day. I think that the supplement facts on the back of the bottle are pretty much standard. Couldn't help but notice while most of the listings are 100% DV, phosphorus was only 11% and potassium was only 2%, why is that? Also, what kinds of foods, or herbal supplements are rich in phosphorus & potassium?
