Thanks sharing your website here, I have seen and read it. I must say and will not recommend any supplements than USANA. In history, they are only two things given by Albert Einstein Award. One is Dr. Linus Pauline who discovered Vitamin C and Dr. Myron Wentz who is the founder of USANA. I believe most of the supplement has a bad effect so we must be cautious and I choose not to take Centrum inside my body after doing some research. Most of the supplements can do harm than good, but don't include USANA because it has clinically based research. I don't recommend anything other than that.
