@ipg, osteoporosis really elicits myriad concerns. I laughed when you didn't mention fracture.
I was certain when I was 50 that I'd have osteoporosis and that I'd eventually take Forteo. Part of the delay for me was that I felt so good. I was 71 when I started Forteo. I wasn't careful, didn't fall and didn't fracture "Don't fall," is excellent advice. Some with osteoporosis fracture and the fall.
I hadn't realized that osteoporosis can cause your jaw to shrink away from the gumline and away from the roots of your teeth. Fortunately for me, it's better to be on Forteo for a while before implant dentistry.
I haven't used Fortibone or Algae Cal; I suspect both are good products.
I worry about too much calcium. I like Solgar products and Jarrow for B12, Folate and K2.
I take magnesium orotate. Because:
Magnesium naturally blocks the formation of hydroxyapatite, the crystal structure that causes calcium to harden in vessel walls.
Magnesium is an essential cofactor for the enzyme alkaline phosphatase, which is required to form new bone crystals. Magnesium integrates into hydroxyapatite crystals to improve bone mechanical strength and flexibility by improving matrix structure.
Regulates Bone Remodeling: It supports the activity of osteoblasts (cells that build bone) and balances parathyroid hormone (PTH) to prevent excessive bone breakdown.
Orotic acid is a mineral transporter that helps magnesium penetrate deep into cell membranes, ensuring high bioavailability.
Orotate also supports the production of ATP (cellular energy), which further aids the metabolic processes involved in bone repair and maintenance.
I've no medical background. You really have to question everything I say.
