I must say my friend ComebackKid is correct on this! It's the same as the argument for multi-vitamins. No multi-vitamin is as good as a single supplement of each. The problem we have is PAYMENT for the products. I will not lower myself to call it money as money died when Gold & Silver were dropped for pathetic paper & basic metal coins. If you have the IOU's to purchase them seperate them use the monopoly money asap, if not then go for the multi units.
