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 and Calcium and Vitamin D

Anyone concerned with bone health, whether taking strontium or not, should have an adequate daily intake of calcium from food or supplements or a combination of the two. In other words, if an individual can get all her calcium from food, she does not need to supplement. However, most people probably will need some calcium supplementation.

The risks of inadequate intake of calcium and vitamin D are reduced calcium absorption, increased serum parathyroid hormone (PTH) concentrations, and bone loss. Low bone mass is a strong predictor of fracture.

There is a rationale for supplementing the diets of elderly subjects with a combination of calcium and vitamin D. Absorption of calcium and possibly of vitamin D and production of vitamin D by the skin decline with aging. Diets deficient in calcium tend also to be deficient in vitamin D because a single food, milk, is the principal dietary source of both these nutrients.

There is no clinical study of strontium with inadequate calcium and vitamin D because such a study would violate the ethical medical standard of doing no harm to patients.

Before inclusion in the TROPOS study of strontium ranelate, patients were subjected to a run-in study to initiate normalization of their calcium and vitamin D status. The duration of this run-in study was 2 wk to 6 months, depending on the severity of calcium and 25-OH vitamin D (25-OH D) deficiency. All enrolled women received daily supplements of up to 1000 mg of elemental calcium adapted to their needs according to their dietary intake (0, 500, or 1000 mg to reach a total daily intake above 1000 mg), and vitamin D according to their serum 25-OH D levels (800 IU for patients having serum 25-OH D lower than 45 nmol/liter and 400 IU for all the others). For patients with severe vitamin D deficiency (25-OH D lower than 30 nmol/liter) the duration of the run-in period was at least 3 months.

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.
