Some of us can be bombarded by claims about the effectiveness of various vitamins, supplements and herbs that are purported to help or eliminate various health issues.
Is there a web site or source that is a focal point for providing credible support or debunking of these various claims?
Please don't simply give a bare link without any useful comments. Also, this question is not inquiring about weight loss products or someone's personal experiences.
Also, not interested in simply knowing the Minimum Daily Requirements for vitamins published by the US FDA.
