Hmm, I'd be a bit skeptical of that info since it is from the product website. No scientific studies are sited. I don't think there is a definitive answer right now. If there were, I'm sure Dr McCormick would know. The main study that people hang their hats on was provided by the manufacturers of Fortibone. I can't imagine Fortibone is any different than other bovine sourced collagen except that it has great marketing and a great name that conjures "strong bones". We really do need more unbiased studies on this.
