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

When you read that 2 grams of strontium ranelate were

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
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
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.
