No strontium is not associated with plaque breaking loose.

You may be confusing strontium with HRT; if one starts HRT after years of no hormones the stiffer cardio system, from a lack of hormones, then becomes more pliable and any existing plaque may break loose. Some doctors use vit K2 to keep calcium plaque in the bones and out of the cardio system. This problem may be controlled with good medical care, vit k2 and with a great doctor who can check you before and during HRT or preferably BHRT use.

BUT....
There was one population study on strontium ranelate that studied all the people, including those with known heart problems, taking strontium ranelate. Surprise, ha, the people with existing heart problems had heart problems.
Several studies tried to duplicate these results but weeding out obvious heart problems to see if strontium produced heart problems but no link was found. Indeed, Denmark ran a population study for a year to see if strontium ranelate was tied to cardio problems, none were found. Some sites report the original report linking strontium to heart problems as flawed.

Still, strontium ranelate is not available in the USA , and I would personally not take it because of the ranelate and the aspartame in strontium ranelate.

Strontium Citrate is available in the USA as a supplement.

No studies on strontium citrate have ever been associated with heart problems. Remember that much of the earth has strontium in its ground water and some areas have very large concentrations of strontium in their ground water. No pockets of cardio problems have been documented in those areas. The US army did note stronger teeth etc for troops with a background in strontium ground water areas.

Why I started on strontium citrate......

Well, I started with conventional medicine, had a bad reaction and no good results from the osteoporosis drugs, I remembered my doctor talking about a new drug with strontium in it for osteoporosis and then I researched, and as my friend says I won the bone lottery (in my belief).

Doctors in my family....

Well, they are family and I know all their weaknesses and poor grades so I approach them as just my nutty brother etc.who has had some life experiences from which I can learn.

My brother in law helped me greatly when I had bell's palsy and the early high-dose corticosteroids (prednisone) just didn't help enough; he suggested the steriod nose sprays to follow the high dose prednisone and it made all the difference. He had seen it help in his practice. You can't duplicate that information on copilot or researching; it takes life experiences.
