WELCOME TO STRONTIUM FOR BONES BLOG
Have you experienced negative, and even dangerous, side effects from Fosamax (alendronate), Boniva (ibandronate), Actonel (risedronate), Reclast (zoledronic acid), Prolia (denosumab), Forteo (teriparatide), Tymlos (abaloparatide), or other drugs prescribed for osteoporosis? If you have, then rest assured there is a safe, effective treatment for this condition. Strontium, primarily in the form of strontium citrate, is taken orally once a day.

How Strontium Builds Bones
Strontium is a mineral that tends to accumulate in bone. Studies have shown that oral doses of strontium are a safe and effective way to prevent and reverse osteoporosis. Doses of 680 mg per day appear to be optimal. See my "For More Information About Strontium" links section.
Osteoporosis is caused by changes in bone production. In healthy young bones there is a constant cycle of new bone growth and bone removal. With age, more bone is removed and less new bone is produced. The bones become less dense and thus more fragile.
Scientists believe that strontium works in two ways. It may stimulate the replication of pre-osteoblasts, leading to an increase in osteoblasts (cells that build bone). Strontium also directly inhibits the activity of osteoclasts (cells that break down bone). The result is stronger bones.
When taking strontium, be sure to take 1200 mg calcium, 1000 IU vitamin D3, and 500 mg magnesium daily. It is best to take strontium late at night on an empty stomach. Calcium and strontium may compete with each other for absorption if taken together.

I am interested in starting Strontium for my osteoporosis of the spine. Do you know of an endocrinologist in the Orange County CA area who would be supportive of this treatment? If not, how might I go about finding someone? I strongly prefer not to take medications.

I do not know of an endocrinologist in the Orange County, CA area who supports strontium citrate for osteoporosis. You need to find a doctor who practices integrative medicine. There are probably more doctors that fit that profile in California than in many other states. However, it is not necessary to have an endocrinologist, or even a GP, to take strontium citrate, which is sold over-the-counter. My GPs did not recommend SrC, but they have ordered my laboratory tests and DXA scans over the years.

Thank you!
Hi BoneLady, I have been taking Strontium for about 1 year, with very good improvement in my lumbar and hips. I had a metabolic panel in 2024 and my egfr was 98%. I had another metabolic panel completed a few days ago and to my dissapointment, my egfr has dropped to 72%. Are there different grades of strontium? I am not taking the AC Strontium, but wondering if it's that my kidneys are not filtering strontium now or if the grade of strontium is effecting my kidneys? I am stopping strontium for the time until my next metabolic panel. I am so disappointed.

Strontium does NOT affect kidney function. I have no way of knowing why your eGFR dropped from 98% (normal) to 72% (mild loss of kidney function) in about one year because I do not know your medical profile or history. You did not mention your age, and eGFR naturally decreases with age, even in people without kidney disease. Also, a single eGFR does not necessarily indicate a permanent problem. With 72% eGFR, your kidneys are able to filter strontium. If you had a severe loss of kidney function, you would not be able to adequately filter strontium or any other product processed by the kidneys. So do not be disappointed. Next time you have a metabolic panel, stop taking strontium for about two weeks prior. I do this every year before my own blood tests because strontium can interfere with some colorimetric tests. Also, before any blood test, be sure to drink lots of water. Dehydration can lead to a temporarily lower eGFR. Certain antibiotics and NSAIDs (like ibuprofen) can affect creatinine levels.
You did not mention what brand of strontium citrate you are taking. Strontium citrate in supplement products is typically Nutrition Grade, Clinical Grade, or Pharma/Nutraceutical/Food Grade, which are all suitable for consumption and meet standards for safety and effectiveness. Nutrition Grade is a common term for strontium citrate used in dietary supplements that are formulated for nutritional purposes. Clinical Grade implies that the strontium citrate has been tested in human clinical trials for safety and effectiveness, as seen with products like AlgaeCal's Strontium Boost. Pharma/Neutraceutical/Food Grade indicates that the strontium citrate meets high standards for use in pharmaceuticals, dietary supplements, and food products, suggesting excellent physical and chemical properties for consumer use.
Good luck! Keep me posted.
