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.

Strontium Malonate

Osteologix, Inc., a specialty biopharmaceutical company headquartered in San Francisco, CA, announced in May, 2008, that the FDA has accepted its investigational new drug (IND) application for NB S101 (strontium malonate) to treat and prevent osteoporosis. See links to three articles on this topic at the end of this blog.

I am seriously considering taking the Strontium Malonate for my osteoporosis. I am curious, where can the supplements be purchased?

You cannot currently buy strontium malonate in the U.S. Whenever it does become available, you will need a prescription to obtain it.

You can buy strontium citrate as a supplement from many health food stores and online distributors, such as and

The purpose of my post was to inform readers of the progress Osteologix is making towards their goal of someday marketing strontium malonate. Getting a drug to market is a lengthy procedure. It will be several years before this drug can be sold in the U.S. Below is a statement from the company's president and CEO:

"Based on the Notice of Allowance and the claims allowed by the USPTO, we believe the intellectual property protections established by this US patent allowance, coupled with our recently upheld European equivalent, will significantly enhance our ability to finalize strong development collaborations with potential partners to complete the Phase III development of NB S101 in osteoporosis," stated Philip J. Young, President and Chief Executive Officer of Osteologix.

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.
