I just began looking into them once I bought that book on vitamins and minerals.
Anyways, recently, I bought that Centrum Protegra, the one that I believe is the best one they had based on their vitamins and minerals.
The only thing they don't seem to have enough of is Vitamin C (10,000IU). They only contain about 1,000IU. And they contain about 250mg of calcium. -_-'' Yeah, this is why I began to take some of my mothers calcium pills. Each tablet contains about 333mg of it, so I take about 3 of them daily (1,200mg).
