Abstract: A composition of matter includes an effective amount of strontium carbonate for affecting bone metabolism. The composition is substantially free of calcium to avoid absorption competition in the digestive tract. The composition is also preferably substantially free of chelating agents, phosphate, phytic acid, oxalates, insoluble fibers, and non-strontium divalent cations or other materials that compete with strontium ions for absorption in the human digestive tract. Other ingredients are optionally added to increase strontium absorption or for their independent positive effective on bone health, including for example vitamin D and vitamin K, quercetin dihydrate, and hesperidin. The composition is preferably administered as a chewable food by blending with a chewable food matrix to form a palatable food that is readily consumed.
