Strontium is a mineral that is naturally found in the earth, in food, and in bones. Strontium Boost contains the mineral strontium bound to citrate (i.e., citric acid from fruit) to form (natural) strontium citrate.

Strontium Boost is the only strontium citrate product backed by human clinical studies showing its safety and efficacy when it comes to low bone density. We’re so confident that we guarantee your patients will see an increase in bone density when using Strontium Boost, together with AlgaeCal Plus, for at least 12 months. See guarantee details.

Patients with chronic kidney disease (CKD) should avoid strontium or be monitored carefully. Since the mineral is eliminated by the kidneys, it may accumulate in CKD patients or others whose blood-filtering capabilities are compromised.

Strontium citrate has been shown to both increase osteoblast (bone-building cell) activity and modulate osteoclast (bone-clearing cell) maturation. Strontium primarily deposits in the spongy part of newly forming bone (trabecular bone), which 1) improves the mineralization and formation of healthy bone crystals; 2) makes them more stable and resistant to compression damage; and 3) increases the number of bone-forming sites resulting in reduced fracture risk.

Some confusion exists due to a pharmaceutical product called strontium ranelate. This synthetic form used significantly higher doses of strontium and combined the mineral with ranelic acid. While the drug showed positive effects on bone health, it produced some undesirable side effects. Strontium ranelate’s use is now limited in Europe and the drug has never been approved by the U.S. Food & Drug Administration or Health Canada.

Strontium citrate, the form in Strontium Boost, has an excellent safety record. In more than 100 years of research (including recent human studies), no adverse effects have been reported for a natural, stable strontium salt, as long as it’s taken with adequate calcium. Independent of any increase in bone density, strontium citrate strengthens bones safely and naturally with no adverse side effects.
