WELCOME TO STRONTIUM FOR BONES BLOG

Have you experienced, or read about, negative, and even dangerous, side effects from Fosamax (alendronate), Boniva (ibandronate), Actonel (risedronate), and other bisphosphonates prescribed for osteoporosis? If you have, then rest assured there is a safe, effective treatment for this condition. Strontium, primarily in the form of strontium citrate, is taken orally once a day.

BMD Improvements With Strontium

Research indicates that over three years, strontium can improve bone mineral density by 8-14%, depending on the site. These findings come from three studies on strontium ranelate (STRATOS, SOTI, and TROPOS). One study on strontium malonate (Strong study) showed a 2.66% increase in BMD at the lumbar spine after just three months. The University of California at Davis (UCD) is conducting a three-month clinical trial on strontium citrate, but the results may not be available before May, 2010.

The STRATOS trial (2002) of strontium ranelate determined that 680 mg strontium was the optimum dose. It was followed by a much larger study (SOTI study, 2004) of 1,649 osteoporotic postmenopausal women over a three-year period. Participants that received 680 mg of strontium daily, along with calcium and vitamin D supplements, increased lumbar bone mineral density by an average of 14.4% and femoral neck BMD an average of 8.3%.

The TROPOS study in 2005 focused on non-vertebral fractures in 5,091 postmenopausal women with osteoporosis. After five years, this double-blind, placebo-controlled study found an 8.2% improvement in the femoral neck and a 9.8% improvement in the total hip bone density.

In 2007, Osteologix, Inc. announced the results of its phase II clinical trial (Strong study) involving 289 postmenopausal women with low bone mineral density. The company reported that after three months, a 680 mg dose of strontium malonate increased lumbar spine BMD by 2.66%.

This is quite exciting. So do the studies say anything about side effects from taking strontium?

Jill,

Yes, side effects are covered in the studies. See my post of Wednesday, September 23, 2009 entitled "Strontium Ranelate Safety." Also, click on the link "Post-Marketing Assessment of the Safety of Strontium Ranelate" in my reference section.

I'm sorry...after I made my comment I went on to read further in your blog and found the side effects. They have scared me and I'm not sure what to do now.

Jill,

Only you can make the decision about which supplements and/or medications to take. The only way to make informed decisions is to learn all you can from reliable sources.

Most people experience no side effects from strontium citrate or only mild gastrointestinal effects. Most of the clinical trials have been on strontium ranelate. The incidence of more serious side effects has been low. According to one post-marketing assessment,"age-adjusted rate ratios for venous thromboembolism, gastrointestinal disturbance, minor skin complaint and memory loss were 1.1 [95% confidence interval (CI) 0.2, 5.0], 3.0 (95% CI 2.3, 3.8), 2.0 (95% CI 1.3, 3.1) and 1.8 (95% CI 0.2, 14.1), respectively."

How Strontium Builds Bones

Strontium is a mineral that tends to accumulate in bone. Studies have shown that oral doses of strontium are a safe and effective way to prevent and reverse osteoporosis. Doses of 680 mg per day appear to be optimal. See my "For More Information About Strontium" links section.

Osteoporosis is caused by changes in bone production. In healthy young bones there is a constant cycle of new bone growth and bone removal. With age, more bone is removed and less new bone is produced. The bones become less dense and thus more fragile.

Scientists believe that strontium works in two ways. It may stimulate the replication of pre-osteoblasts, leading to an increase in osteoblasts (cells that build bone). Strontium also directly inhibits the activity of osteoclasts (cells that break down bone). The result is stronger bones.

When taking strontium, be sure to take 1200 mg calcium, 1000 IU vitamin D3, and 500 mg magnesium daily. It is best to take strontium late at night on an empty stomach. Calcium and strontium may compete with each other for absorption if taken together.
