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.

How Much Calcium Are You Getting?

To determine how much calcium to supplement, first figure out how much calcium you are already getting. The International Osteoporosis Foundation (IOF) has a calcium calculator to find out if you are getting enough calcium in your diet each day. Remember, women ages 19 to 50 need at least 1,000 mg of calcium daily. Women over 50 need at least 1,200 mg. Here is the link to the calculator:

The current recommended form of strontium to take for osteoporosis is strontium ranelate. The other forms have NOT been proven to be effective.

Strontium ranelate is approved as a prescription drug for post-menopausal osteoporosis in more than 100 countries worldwide. It is not approved in the USA or Canada.

Strontium citrate is available as a supplement in the USA, Canada, and elsewhere. Supplement manufacturers are not required to conduct rigorous clinical trials. However, scientific studies have been conducted on strontium citrate. A recent Canadian study is the COMB study. You can read about it here:

I have been on strontium citrate for more than six years. My bone density keeps getting better. My back feels strong and I feel well.

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.
