Dietary supplements are not snake oil. I've never looked into "Balance of Nature" so I won't speak to that. My point is, if you're looking for a good, natural nutritional supplement, do A LOT of reading and try to find a Naturopath to speak with in your area. It's my belief that everything we need (nutritionally) is on this Earth. However, the only thing an M.D. can (legally) prescribe you is poison, and it will come with 2 pages of "potential" side affects.
