WELCOME TO STRONTIUM FOR BONES BLOG

Have you experienced negative, and even dangerous, side effects from Fosamax (alendronate), Boniva (ibandronate), Actonel (risedronate), Reclast (zoledronic acid), Prolia (denosumab), Forteo (teriparatide), Tymlos (abaloparatide), or other drugs 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.

Visitors to my blog can leave comments or ask questions and can remain anonymous, if they wish. Their comments are relayed to my g-mail inbox.

What Determines How Much Strontium Is in Your Bones?

It is generally said that, for every 1% of strontium incorporated into bone crystal, BMD is overestimated by 10%. However, we do not know how much strontium has been incorporated into each of your bones. 

The amount of strontium in your bones will depend on several factors: 

(1) the dosage (680 mg, as in the COMB study; 340 mg, which is a half dose; or 450 mg, the dosage used in the MOTS study; 

(2) the length of time you have been taking strontium (The COMB and MOTS studies lasted only one year. Therefore, the strontium effect on those DXA scans was less than had the subjects been studied for three years or longer. 

(3) how well you absorb the strontium (Absorption of strontium salts is about 25% for most people with normal absorption, but, as we age, our ability to absorb nutrients, supplements, and medications is often reduced.); 

(4) the individual bones (Some bones absorb strontium better than others.); 

(5) the DXA equipment used to measure BMD.

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.
