Strontium is an important component of bone and therefore its role and efficacy is primarily to maintain bone health. Studies have shown that elemental strontium has the two effects of promoting the growth of osteoblasts and inhibiting the formation of osteoclasts, but excessive intake will increase the prevalence of rickets in children. Strontium absorption in the intestinal tract relies on active absorption of vitamin D. Most of the strontium is deposited in the bone or teeth, and the absorbed strontium is mainly excreted in the urine, with a small amount excreted through sweat. There is not enough research information to set a dietary reference intake, but grains produced in high strontium soils can increase rickets after long-term consumption, so strontium should not be supplemented indiscriminately, but in cases of deficiency it can be ingested under the supervision of a physician and should be monitored dynamically.
