Strontium is an important mineral for bone health and it is found in most foods where calcium is found. In 2002, AOR introduced the world’s first supplemental strontium citrate for those with osteoporosis, osteopenia, post-menopausal women and those at an increased risk of bone fractures. AOR’s Strontium Support II comes in two sizes and provides an effective dose of this bone health powerhouse in a convenient two capsule-a-day formula. 

Strontium is a mineral that actually helps rebuild bone. While supplements like calcium, vitamin D and vitamin K maintain bone health, and conventional bone drugs reduce bone degradation, strontium actually increases osteoblast production while decreasing osteoclast production, resulting in increased bone development and decreased bone loss. Since strontium is similar in molecular structure to calcium, it is thought to activate the calcium receptors in the bone, stimulating the building of new bone and telling the body to use calcium effectively in bone tissue, while inhibiting bone breakdown. A recently published study showed that strontium was not only safe to take over the course of 10 years, but also that it continued to reduce the risk of osteoporotic fractures throughout this time period. Strontium Support II is an excellent addition to calcium supplementation for those with osteoporosis or osteopenia, post-menopausal women or those at an increased risk of bone fractures.

Strontium is a trace mineral which concentrates in the skeletal system, where it supports the function of osteoblasts (the cells which form new bone) while reducing the differentiation and activity of osteoclasts (the cells which resorb old bone). Strontium Support II helps support bone mineral density.

Supplement Facts

Amount Per Serving Amount: 1 Capsule
341 mg Strontium (citrate)
Non-medicinal ingredients: Capsule: hypromellose.

AOR™ guarantees that all ingredients have been declared on the label. Contains no wheat, gluten, corn, nuts, peanuts, sesame seeds, sulphites, mustard, soy, dairy, eggs, fish, shellfish or any animal byproduct.

Suggested Use:

(Adults 50 years and older): Take 1 or 2 capsules daily on an empty stomach, at least two hours before or after consuming food, calcium or milk since these can significantly reduce strontium absorption if taken together. Ensure an adequate daily intake of calcium and vitamin D.

Cautions :

May cause temporary transient increases in levels of creatine kinase that are unassociated with any disorder. Discontinue use and consult a health care practitioner in case of rash or hypersensitivity, as this may be a sign of a serious allergic reaction (DRESS or Stevens-Johnson syndrome). Consult a health care practitioner for use beyond 6 months. Pregnant and breastfeeding women, those who have or are at high risk for blood clots (e.g. if you are temporarily or permanently immobilized, over the age of 80, taking birth control pills, etc.), heart diseases and/or circulatory problems (e.g. Venous Thromboembolism (VTE), heart attack, peripheral arterial disease, stroke, high blood pressure, hyperlipidemia, diabetes, etc.), or have kidney disease must not use this product.

Age-Related Bone Loss Bone loss accelerates suddenly in menopausal women because the drop in estrogen levels causes an increase in the resorption (teardown) of existing bone. But resorption is only half of the story. Age-related bone loss is also caused by a decrease in the formation of new bone tissue. Strontium: The First Bone-Building Supplement! Strontium is a mineral that is able to inhibit bone resorption while simultaneously stimulating bone growth. This effect appears to be due to strontium's ability to actually increase the production of bone-building cells (osteoblasts) and decrease the production of bone-destoying cells (osteoclasts), shifting the balance toward bone growth. This is a remarkable benefit provided by taking strontium as a supplement, and no other natural substance or drug is known to provide this dual effect. People who are concerned about preserving and regaining healthy bones
Current Bone Health Options Existing drugs for treating osteoporosis work by reducing bone resorption. But they do not support the formation of new bone. These drugs reduce the rate of bone breakdown, but they do not help the body to build new bone tissue. In fact, within weeks of starting use of antiresorptive drugs like Fosamax,
In 2002, AOR was the first company in the world to produce supplemental strontium citrate.
Strontium Ranelate Most of the clinical studies that found strontium effective for reducing fractures and increasing bone density were done using strontium ranelate. This form of strontium is a prescription drug used in Europe with excellent results and minimal side effects. However, the "ranelate" portion of this salt form of strontium is inactive; only the strontium produces physiological benefits. The use of strontium ranelate allowed a patent to be developed to protect this amazing discovery. Studies using other forms of strontium are few, but they do exist and also show pronounced effects against bone degeneration, showing that strontium is the important molecule. In a study using strontium ranelate, BMD showed an increase continuously over 10 years in osteoporotic women. The incidence of vertebral and nonvertebral fracture was lowered between 5 and 10 years than in a matched placebo group over 5 years. Therefore, the results proved that Strontium ranelate's antifracture efficacy appears to be maintained long term. Another study investigated bone microstructure changes as a target in osteoporosis treatment to increase bone strength and reduce fracture risk. 83 postmenopausal women with osteoporosis were given a dosage of 2g per day of strontium ranelate for a two year period. The double-double blind exploratory trial observed both bone mineral density and bone turnover markers. Distal tibia bone microstructure was assessed by high-resolution peripheral quantitative computed tomography. Both both density and bone thickness were shown to have increased

It's easy to see why many people can become obsessive with their eating habits and lose their love of food.
