Fish oil increases bone formation by favorably influencing osteoblast function.1 Additionally, Dr. Dan Murphy points out that fish oil decreases the release of proteoglycan metabolites from articular cartilage and abolishes the aggrecanase and collagenase activity.2
As recent as Feb. 04, Endocrinology reports that, “Nitric oxide (NO), in addition to its known atheroprotective effects, appears to also play a role in osteoblast function and bone turnover.”3
Lowering even mildly elevated levels of homocysteine increases the risk of oteoporotic fracture. Homocystinuria may weaken bone by interfering with collagen cross-linking. Increasing the integrity of collagen cross-linking is a completely different mechanism of strengthening bone, compared to increasing bone density!4
The Moral of the Story
Lots of nutrients will support heart disease, and lots of nutrients help to build bones; but several nutrients work on DIFFERENT levels for both heart and bone, and utilizing some of these nutrients may allow you to focus on efficiency and kill 2 goals with the same pill.
