Strontium NOT Approved by FDA for Osteoporosis

Although most minerals that are essential for bone health can be obtained through a diverse diet, some are added in excess to supplements.  The most common are calcium, zinc, manganese, copper, and one you may be less familiar with – strontium.
Strontium should be questioned for bone health and osteoporosis. It is not considered an “essential” nutrient for bone health and it has unique properties that differentiate it from the others mentioned above.

The body absorbs strontium as if it were calcium, when in fact strontium is a much heavier element.  It is so heavy, in fact, that it actually displaces calcium in bone.


Strontium has gained attention lately for its purported ability to improve bone density and mineralization, as measured by x-ray tests.  These reports have not always considered strontium’s weight, which in addition to displacing calcium also absorbs the x-rays itself and makes the bone appear more dense!  If you need more proof, strontium was even used in early television tubes to absorb x-rays to help protect viewers from irradiation.
Another recent application of this metal is as strontium ranelate.  Strontium ranelate is available by prescription under various names in some 70 countries for the treatment of post-menopausal osteoporosis.  When taken by mouth at up to 2 mg per day on average strontium renelate shows improved bone strength and reduced fracture rates in women with osteoporosis.
But the risks of taking strontium ranelate can be serious – increased risk of blood clots and memory loss have been reported. Strontium is also known to accumulate and remain in the body for long periods of time.  For these reasons the United States Food and Drug Administration (FDA) has not approved the use of strontium ranelate for U.S. consumers.
The concerns about strontium were recently published in The Open Orthopedics Journal.  We agree that more evaluation is needed before strontium becomes a routine treatment for osteoporosis, so we agree with the FDA’s recommendation. Silical™ System* specifically does not contain strontium in any form or any Questionable Nutrients In Supplements
*Adequate calcium and vitamin D, throughout life, as part of a well-balanced diet, may reduce the risk of osteoporosis.
