Strontium citrate (Algaecal) and fractures

@tonilynn I found this on-line: "Strontium can skew DEXA scans because it has a higher density than calcium, which can lead to an overestimation of bone mineral density. This means that while strontium may improve bone density, it can create misleading results in DEXA measurements for up to ten years after stopping supplementation."

@loplady Would the problem of Strontium causing inaccurate DEXA results be eliminated if patient discontinued taking Strontium 24 hours, possibly longer, before their DEXA scan---like taking calcium or iron needs to be discontinued 24 hours before a DEXA?

@daisy17 Then might REMS be a viable bone density scanning alternative?
"REMS is not affected by strontium. The problem with strontium and dexa is the radiation and how it reacts to the denser strontium. REMS Echolight does not use radiation."

"BMD measured by ultrasound is not affected by the strontium content of bone. An in vitro study concluded that aBMD measured by DXA was prone to overestimation in the presence of strontium, but acoustic parameters measured by quantitative ultrasound (QUS) are independent of strontium concentration."

I had a bad reaction to Strontium Citrate (Algae Cal) I started to develop a rash after just a few doses. I immediately stopped taking when I came across a case of a woman that became covered in hives after 6 weeks of strontium citrate. I was lucky to find the woman's case and stop the strontium immediately. Rashes have subsided for the most part. Happy I did not continue and end up like the poor woman. https://pmc.ncbi.nlm.nih.gov/articles/PMC7985217/

@blueberre
The case which you cite is a case of DRESS, eosinophilia and systemic symptoms syndrome with an added granulomatous dermatitis. This is not a typical rash.
This is a reaction which can be found in reaction to drugs, supplements, even some foods, The woman in the population study of one was taking a wide variety of drugs and supplements. The report could not distinguish what might have caused her reaction. Her outpatient medications included levothyroxine, sumatriptan, topiramate, trazodone, and alprazolam. She also reported taking one supplement called “elderberry.” She eventually recalled taking 3 other supplements: Sleepwell, AlgaeCal Plus, and strontium citrate.
It seems that she was taking a double dose of the strontium citrate, 2times 680mg.; using algaeCal and strontium citrate, both which have strontium citrate in them.
I can find no records in research of links to the correct dose of strontium citrate; this one case is the only one which had any strontium citrate in its research .
To repeat DRESS syndrome can be tied to many supplements, drugs and even food.
Taking double the dose of any drug, supplement or every food or water can have terrible consequences.
We don't know what caused her reaction; we do know that she used a wide variety of drugs and supplements and seems to have at least use strontium very unwisely.
To quote Narnia: "Aslan is not a tame lion" , neither is strontium citrate or any drug or supplement a toy.

@kathleen1314 I agree that her reaction and mine may not be the same. I do know that I hesitated to take the strontium . I finally started due to good reviews and within 2 days, I had hives. Coincidence? Maybe, but I had taken nothing different than my regular vitamins. I have never had hives before, so I still feel that strontium caused my reaction . It is starting to subside after 3 days without taking the strontium again. Algae Cal was quick to refund me when I contactd them. Just cautioning others.
