What is Strontium? (Strontium Citrate)

Strontium Strontium Citrate

"Strontium Bone Support" Strontium Citrate supplement is an organic, stable strontium form (not the radioactive strontium-90 isotope!).

There has been a lot on the news about unknown quality supplements on the market. Relentless Improvement Strontium is the only fully documented product in the world, providing a public Certificate of Analysis, tied by lot number to the product shipped to you.

Also of concern to consumers are strontium products that do not disclose the "elemental" content in mg. It is critical that you compare apples to apples. If a product seems too good to be true, please be a careful shopper and read the label.

Strontium is a trace mineral in the diet whose metabolism is closely tied to that of calcium, and which concentrates in the skeletal system, where it supports the function of osteoblasts (the cells which form new bone) while reducing the differentiation and activity of osteoclasts (the cells which resorb old bone).

Extensive evidence supports a role for strontium citrate in skeletal health.

Strontium Citrate A Bone-Building Supplement

Strontium is a mineral found along with calcium in most foods. Research has long suggested that it may be an essential nutrient required for the normal development, structure, function, and health of the skeletal system. Clinical trials going back into the 1940s have supported this conclusion, but recent studies have provided evidence that it can offer unique nutritional support against loss of bone structure and function.

Human clinical trials support the ability of Strontium to both support new bone formation and prevent excessive resorption.

Recent large-scale, double-blind, placebo-controlled trials using the ranelic acid salt of Strontium have proven that Strontium supplements combined with calcium and vitamin D dramatically build bone mass, reduce the incidence of spinal deformities, and slash hip fracture risk compared to calcium and vitamin D alone.

  • In a three-year trial involving 1649 women with postmenopausal osteoporosis, women receiving only calcium and vitamin D suffered the loss of 1.3% of their lower spinal BMD, while women also taking Strontium supplements at 680 milligrams per day increased their bone mass by an astounding 14.4% at the spine, and by 8.3% in the large bone at the top of the thigh.
  • Women taking Strontium supplements were spared 41% of the new vertebral fractures that befell women taking calcium and vitamin D alone.

A second trial showed that Strontium supplements are just as effective against hip fractures. In this study, 5091 postmenopausal women with osteoporosis received calcium and vitamin D supplements, along with 680 mg of Strontium or a dummy pill. Taking Strontium supplements allowed women to avoid 41% of the hip fractures suffered by women taking only calcium and vitamin D. Although it was a three year study, the benefit began to manifest in just a year and a half.

A third trial shows that Strontium supplements can also protect the bones of women who do not yet have osteoporosis. In this study, 160 women in early menopause, but without osteoporosis, took either calcium supplements alone, or calcium plus Strontium for two years.

  • Women taking calcium alone were subjected to a loss of 0.5% of their lumbar bone mass per year, but women taking calcium plus Strontium (340 milligrams daily) experienced a 0.66% gain annually. The net benefit to Strontium users was 2.46% more lumbar bone mass by the end of the trial. Lower doses (42.5 or 170 milligrams of elemental Strontium) were not effective.
  • Likewise, women adding Strontium to their supplement regimen experienced gains of 2.46% in bone mass at the neck of the femur, and 3.21% in the hip as a whole, compared to women taking calcium alone.
  • Strontium users' lab tests revealed significant increases in markers of bone formation, with no change in markers of bone resorption.

Unlike the range of side-effects that accompany antiresorptive drugs, no clinical side-effects have ever been reported that could be clearly attributed to Strontium.

Calcium and Strontium: Don't Combine

Take your Strontium either three hours after your last meal of the day, or one hour before breakfast in the morning, or both. Because studies suggest that one last dose of calcium just before retiring can help prevent excessive resorption of bone overnight, it may be best to take all of your Strontium before breakfast, leaving you free to take a calcium supplement just before you go to bed.
