You are the best judge of what works for you and only you may decide that.
Research is a different matter though.
You are mistaken when you say that strontium displaces calcium in the bone. It is more accurate to say that strontium has the capacity to bridge the large osteoporic gaps in the bone and then calcium adheres and then bone grows.
You seem to imply that strontium has a part in cardio events.
Strontium Citrate has never been tied in any study to cardio events.
Strontium is found in much of the world's ground water and in some areas of the world is found in high concentrations. If strontium was a cause of any heart conditions then those areas would have shown a definite change in cardio events. In the history of the world, no such population study or research has ever shown a problem in those areas with high strontium content in their ground water.
You may be alluding to that one population study, which has never been able to be reproduced, which showed a rise of cardio events in the population of those on strontium ranelate, people who also had existing cardio problems. Other population studies which eliminated existing heart patients found no tie of even SR to cardio events. Denmark studied the SR for a year and found no tie to cardio events.
Still, it is always best to be safe:
Evenity, prolia and Forteo all have ties to some type of cardio event. In addition, calcium supplementation has also been associated with cardio events.
Strontium citrate has never been associated with any cardio events.

@karenjaninaz that’s a lot of medicines !….and of concern to me as time goes on and new health issues come up, so I am personally researching the simplest ways to take care of my present needs to avoid negative drug/supplement interactions, especially as time goes on. What often happens is people end up taking meds to deal with med side-effects, very common with cancer drugs !
