Has anyone been on AlgaeCal supplement?

Hi, my Dr. recommended Algaecal supplement for my osteoarthritis because I don't want to go back on Fosamax. side effects include sarcoma of the jaw. Has anyone been on this supplement? results? It's pretty costly and my insurance won't cover it.

Interested in more discussions like this? Go to the Osteoporosis & Bone Health Support Group.

I took Algaecal for a year but had terrible stomach issues with it. I think it’s a good product if you don’t get the gastrointestinal side effects.

I have a sensitive gut and phased it in slowly and have had no issues.

There is sufficient evidence that taking it five years can cause femur fractures. Ask any ortho.

As I understand it the preferred max time now is to quit fosomax/alendronate at the 5 year mark. I also believe from what I have read that the reports of femur fracture are rare.
