Thorne's Oscap is a comprehensive bone support supplement.* Although everyone loses bone density as they age, certain groups are particularly at risk. As many as half of all women in the United States older than 65 should be concerned about maintaining good bone health. Oscap contains dicalcium malate and dimagnesium malate (two calcium or magnesium molecules each bound to one molecule of malic acid) for enhanced absorption and greater concentration of these important minerals.* Adequate magnesium intake promotes bone density by optimizing the secretion of parathyroid hormone and facilitating active calcium transport to the bones.*Oscap provides vitamin D3, which facilitates the absorption of calcium; boron, which assists the body's metabolism of vitamin D and estrogen; and B vitamins for healthy methylation, which mediates homocysteine levels.* Oscap contains methylcobalamin (an active form of vitamin B12), L-5-methyltetrahydrofolate (the active form of folic acid), and pyridoxal 5'-phosphate (the active form of vitamin B6) for their function in helping to maintain already normal homocysteine levels.* To provide a bone health formula that can be used by individuals taking a blood-thinning medication, Oscap does not contain vitamin K.**
