Strontium for Bone Health
Strontium has been safely used as a medicinal substance for more than a hundred years. It was first listed in Squire's Companion to the British Pharmacopoeia in 1884. Subsequently, strontium was used therapeutically in the United States and Europe. As late as 1955, strontium compounds were still listed in the Dispensatory of the United States of America.
The processes of bone resumption and formation are tightly governed by a variety of systemic and local regulatory agents. In addition, minerals and trace elements affect bone formation and resumption through direct or indirect effects on bone cells or bone mineral. Some trace elements closely chemically related to calcium, such as strontium have pharmacological effects on bone when present at levels higher than those required for normal cell physiology. The human body contains approximately 320 to 400 mg of strontium in bone, and connective tissue. If we look at clinical studies, indeed, strontium was found to exert several effects on bone cells. In addition to its antiresorptive activity, strontium was found to have anabolic activity in bone, and thus may have significant beneficial effects on bone balance in normal and osteopenic animals. Accordingly, strontium has been thought to have potential in the treatment of osteoporosis.
In a three-year, randomized, double-blind, placebo controlled study using 680 milligrams of strontium daily, women suffering from osteoporosis experienced a 41 percent reduction in risk of a vertebral fracture, compared with placebo. And, overall vertebrae density in the strontium group increased by 11.4 percent but there was a 1.3 percent decrease in the placebo group.
In a second study, 353 women who had suffered at least one vertebral fracture due to osteoporosis took varying levels of a prescription medication for of strontium referred to as strontium ranelate or a placebo. The women who took 680 milligrams of strontium daily had an increase in lumbar bone mineral density of approximately 3 percent per year, significantly greater than placebo. By the second year of the study, there was a significant decrease in additional fractures in the strontium group as compared with the placebo group.
These studies, the benefits of strontium ranelate (reducing fracture risk by as much as 50%) and the history of strontium in medical practice were discussed as an editorial in the New England Journal of Medicine, January 29th, 2004.
Further, scientists are looking into the benefits of strontium for osteoarthritis because researchers hypothesized that strontium might also improve cartilage metabolism, and for dental caries since 10% of subjects that had no dental carries in a 10 year study sponsored by the US Navy, resided in a small town that had unusually high levels of strontium in the municipal water supply.
Strontium is available as strontium carbonate, strontium chloride, strontium sulfate, strontium gluconate and strontium citrate. In clinical research strontium gluconate was absorbed better than strontium carbonate. It is my clinical opinion that strontium citrate is absorbed better than the other forms of this mineral.
Remember that strontium is very closely related to calcium. They both utilize the same carrier protein for transport. Calcium will win this tug of war effortlessly. The take home message is to take strontium 4 hours away from Calcium (preferably other minerals as well) before bed. Currently, I dose strontium at 681mg in one dose prior to bed (each strontium citrate capsule contains 227mg of pure strontium citrate = 3 capsules) on an empty stomach (defined as 2 hours after a meal).
