I started taking Osteo Collagen-Pep (Fortibone) from Dr. McCormick's site back in late November, or early December. It's really good quality at a great price. Whether or not it's helping, I can't say because I've made so many changes (medication, diet, supplements, exercise and stress reduction) that any or all of them could be adding benefits.
I am doing something right. My first DEXA was in January of last year. I had my second DEXA two weeks ago, and it showed a 7.2% improvement in my spine. The hip is unchanged (not worse :))
I guess the only way to know if Fortibone specifically is making a difference is to only take that and do nothing else. I just take it because it MAY help, and it doesn't seem to be doing any harm. The way that I see it is that even if each thing I'm doing to better my bone metabolism works to a small degree, together it could add up to a significant improvement.
