Strontium Products, Inert Ingredients, and Dosages

I have used Doctor's Best Strontium Bone Maker successfully for six and a half years. For people who cannot tolerate magnesium stearate, which is in Doctor's Best and most vitamins and supplements, I recommend AOR Strontium Support II or Pure Encapsulations Strontium Citrate because they contain no fillers. These three brands are reputable. There are other reputable brands. These are three I know of. Do not purchase supplements solely on the basis of cost. Some brands of strontium citrate may not even contain the amount of strontium stated on the label.

When you read that 2 grams of strontium ranelate were used, that means 2 grams (2000 mg) of the strontium salt. Strontium is the bone-active component and makes up 34% by weight of the whole molecule; so, each 2-g dose of strontium ranelate delivers 680 mg of elemental strontium.

I mention sr. ranelate because many people have read the clinical trials on this prescription drug, which is unavailable in the USA and Canada. The following is information on three brands of strontium citrate:

One serving (2 capsules) of Doctor’s Best Strontium Bone Maker contains 680 mg elemental strontium from 1,944 mg (a little less than 2 grams) strontium citrate.

Each capsule of Pure Encapsulations Strontium Citrate contains 227 mg elemental strontium. The serving size is 1-3 capsules per day for 227, 454, or 681 mg strontium per day.

For Advanced Orthomolecular Research AOR, Advanced Series, Strontium Support II, the serving size is one to two capsules, with each capsule containing 341 mg elemental strontium from strontium citrate. Two capsules contain 682 mg strontium.

These are the serving sizes given by the manufacturers. Most research suggests 680 mg is the optimal amount of strontium to treat osteoporosis; 340 mg is probably sufficient for osteopenia.
