I had osteoporosis diagnosed shortly after menopause and was put on Fosamax by my physician. I saw very little improvement in hips, and worsening of spine, taking Fosamax and took myself off it after 4 years due to severe side effects including nausea, vomiting, heartburn, etc. My doctor never heard of strontium citrate for bone building. Based on reading on my own I then tried a natural combination of algae calcium and strontium citrate supplements (680mg nightly).
My stomach problems disappeared and I have steadily gained bone density over 4 years, including a whopping 10% increase in my spine and 6-8% hips in the last two years. I’ve had no ill effects taking strontium. I am now in osteopenia territory and very happy with my progress
