Guest guest Posted February 16, 2008 Report Share Posted February 16, 2008 All the hocus pocus about strontium isotopes should never be put on for laymen. Strontium isotopes are not on the market. They are made by nuclear scientists. The strontium available as nutritional supplement is the natural, stable strontium. For comparison, there are isotopes of calcium, potassium, iodine etc. you name it, but they have nothing to do with nutrition. Read the article on vrp.com. It summarises the practical aspects. If your doctor knows anything about strontium, he/she is one in a thousand. Most doctors are unaware of strontium as bone builder because they are constantly being brainwashed about those " phantastic " bone builders like Fosomax, Boniva etc.which are dangerous and should have been pulled from the market years ago. Read the legal proceedings on the web. My dental surgeon says these products bring him lots of clients when their jaw bones deteriorate and need rebuilding !!! Having a PhD in chemistry gives me a better basis to judge these things. Good Luck wiccantwinpaths wrote: > > > > > > Sounds good - What strengthof Strontium should I look for?

Guest guest Posted February 16, 2008 Report Share Posted February 16, 2008 And your PhD in chemistry makes you a better judge of when a person should discuss something with their doctor??? My experience with doctors is that as an educated consumer it is totally possible to bring up something that they are not familiar with, but that only gives them nudge to learn about it. I always discuss things with my doctor, and I would never trust anyone who tells me not to bother because they know more than any silly brain washed doctor. The leaflet on the European approved osteoporosis medication says this: You should stop taking PROTELOS if you have to take oral tetracyclines or quinolones (two types of antibiotics). You can take PROTELOS again when you have finished taking these antibiotics. If you are unsure about this ask your doctor or pharmacist. The non approved supplements say they haven't been evaluated and aren't medicine. The studys clearly show that the best benefit is only in the 1st year, and that it goes down in benefit after that ... being only minimal beneficial after 5 years. I strongly suggest that anyone who wants to take a supplement like this, with such a clear short life and clear warnings NOT to use it at the same time as tetracyclines should discuss it with their doctor. And while they may not know anything about it at the beginning, they will most likely either learn or refer you to someone who can. > > > > > > Sounds good - What strengthof Strontium should I look for?

Guest guest Posted February 17, 2008 Report Share Posted February 17, 2008 hi group, One of the most recent topics here has been strontium and many of us had or have no clue as to what is it and it's benefits. My last visit with my AP doctor, Dr Brownstein, we discussed the Boniva bone builder I've been taking for about 1 1/2 yrs, recommended by my OBGYN. I've certainly had my reservations about it and recently purchased one of Dr. B's DVD's which dedicated a segment to those types of meds or treatments. After watching it a couple of times, decided it was time to discuss it with him. Long story short, I made the decision to discontinue the Boniva, continue taking calcium (purchased from his office), continue also with D and add " strontium " which he recommended. That was the first I had ever heard of it. When, I think it was , who stated that if your doctor knows about Strontium, consider yourself fortunate cause he's one in a million....not quoting you . We will see when I have my next bone density, in about 2 yrs, cause I had one recently. So it sounds like Strontium is something we should all know about and again, it's so beneficial and educational to all discover and discuss these issues on this site. thanks...good health to all!
