I am currently taking Key Collagen sold by Nutrikey. It has 5 mg of FORTIBONE and it also has three other types of collagen peptides by Gelita.

In a few days, I will run out of Key Collagen and I'm switching to a product with 5 mg of FORTIBONE only. This product is sold by Dr. R. Keith McCormick. It's called Osteo Collagen-Pep. I'm switching because it is less expensive than the product by Nutrikey and I'm not convinced collagen peptides are effective so I only want the FORTIBONE.
I don't know if it's working, yet. My next DEXA scan will be in a year. I've been taking FORTIBONE for six months. The two studies that I know of participants took it for a year.
