I’m wondering if you know who the National Council of Health Fraud is. It’s run by Stephen Barrett, MD, actually a psychiatrist, who has never said anything good about “alternative” medicine including of course, supplements. I think it changed it’s name into quackwatch for whatever reason but it’s reason for existence is clear, that anything outside of conventional medicine is useless, fraudulent or dangerous. It’s interesting that you focused on one product out of the roughly 85,000 different supplements. Maybe because, as you said, it is heavily advertised. By the way, I am not a fan of prevagen and don’t take it or wouldn’t recommend anyone take it either. I agree it’s a very expensive supplement with little science to back it up. On the other hand that still leaves roughly 85,000 different ones to choose from and I guarantee there are many that are more effective and safer than many of our drugs.
