Strontium is a naturally occurring mineral present in water and
food. Trace amounts of strontium are found in the human
skeleton. Strontium has an affinity for bone and is taken up at
the bone matrix crystal surface. The influence of strontium on
the bone metabolism has been researched since the 1950's.
Studies indicate that strontium positively affects bone
metabolism to promote bone formation and decrease bone
resorption, leading to normalized bone density. The Role of
Stable Strontium in Human Bone Strontium is found naturally in
the human skeleton. The level of strontium in bone tissue is
approximately 3.5% of the calcium content of bone. Strontium
taken orally through the diet and from supplements is
preferentially incorporated into the teeth and bones. Research
suggests that the oral absorption of strontium is dependent on
age and decreases with increasing age. Scientists have suggested
two methods of absorption of strontium from the gastrointestinal
tract: passive diffusion and carrier-mediated absorpt
