Why not Strontium Citrate?

Posted by oknowwhatpixie @oknowwhatpixie, Mar 14 11:45am

Has anyone had any adverse effects with Strontium Citrate?
I've been using for about 10 months and have not had any issues.

After being on BHRT and Strontium Citrate for about 10 months. My recent DEXA with TBS shows improvements in my spine. My spine was the area in osteoporosis

January 2025 TBS L1 - L4 = 1.391
March 2026 TBS L1 - L4 = 1.429
TBS has improved which is the best indicator at this time that things are headed in the right direction.

Acknowledging that my DEXA BMD & TScore numbers are skewed due to the Strontium Citrate.

Lumbar Spine TScore -2.5 (0.775) *** prior 2025 was -3.5 (0.659)
Left Femoral Neck TScore -1.9 (0.640) *** prior was -2.2 (0.600)
Left Hip TScore -1.8 (0.724) *** prior was -2.3 (0.659)

Glad you are joining. Under the main heading Osteoporosis there are a number of subcategories. There is much written about strontium citrate. You will find more discussion, research links and people's experiences.

If you have any kidney issues, even mild ones, think twice about strontium.

@nycmusic, Please explain what happened to your kidney when taking Strontium. I am considering taking it again, instead of Prolia or Reclast which have been recommended by my endocrinologist. Thanks

@drsuefowler it isn’t something I have yet taken…but I am checking supplements effects on kidneys, as my kidney #s can be borderline and I don’t want to stress them. I have read on several sites that strontium supplements can be hard on kidneys….am currently trying to balance helping my bones and avoiding stress on kidneys..

Thanks @nycmusic. I think you have a point. All medications and supplements can stress the kidneys. We need to really think about anything we take.

I have had no side effects and have been using Strontium Citrate for 8 months so far. It is part of my regimet with the AlgaeCal program. I have yet to take a new DEXA test so I'm keeping my fingers crossed that when I do in July, I will show improvement in my scores! Congrats on the great improvement!!

Resistance training such is weight lifting is important to bone density and health in general. Here are several links on use of strontium.

Is strontium citrate an acceptable substitute for calcium supplements? Does it have undesirable risks/side effects. I am a female over 70 with Dx invasive ductal breast cancer, osteoporosis, taking Letrozole?
My Endocrinologist is recommending Risedronate, I am currently taking Calcium & Vitamin D supplements. Although I have a history of kidney stones I have not had any for 5 or so years.
