Thanks for taking the time to post the information James. I want to add one thing to what you said.
As far as bone health, bioavailable silica (JarrowSil, BioSil) is the critical element in laying down the collagen matrix to the bone to prevent bone fractures. Without the bioavailable silica, your bones density may increase but the bone quality will be poor hence more brittle and more fracture prone.
Collagen can be increased with Biocell Hyaluronic Acid. Just need to take it with water and on empty stomach. The empirical studies done indicate that the body can turn the type 2 collagen into type 1,3 and so on if needed.
