Supports strong, flexible bones & optimal bone mineral density. Calcium supplements alone do not efficiently support bone growth and bone mineral density. This is a hard fact that I cannot stress enough. Optimal bone mineral density requires myriad nutrients in sufficient quantities. Vitamin D3 supports optimal absorption, Vitamin K2 ferries calcium from the arteries into the bone and magnesium is critical for crystalline bone mineral matrix formation. Calcium, without its important cofactors, can actually harm heart and arterial health. That’s right. Without the symbiotic nutrients calcium needs to properly absorb and make its way into your bones, calcium can end up depositing into soft tissue or adhering to arterial plaque and contributing to the hardening of arteries (atherosclerosis). This can end up leading to cardiovascular disease over time which is why it’s so important to take a calcium supplement or bone health formula that contains these critical cofactors. Vitamin K2’s role in supporting bone & cardiovascular health is crucial. All know that calcium is critical for overall health, especially that of bones. One important fact you may not be aware of though is that calcium needs support from Vitamin K2 to actually make its way from your bloodstream into your bones! This is extremely important as excess calcium in the bloodstream can disrupt kidney health, and actually build up in soft tissue and arteries compromising cardiovascular health. Vitamin K2 helps maintain both cardiovascular AND bone health by ferrying excess calcium from the bloodstream into the bone where it is needed. This also prevents calcium from building up in soft tissues and arteries thereby supporting the maintenance of cardiovascular health as well. Most calcium supplements on the market come from limestone deposits. You read that correctly. Most calcium supplements on the market today are literally inorganic calcium chloride and calcium oxide from limestone deposits. These forms of calcium are famously difficult for your body to absorb and utilize and may even be detrimental to your health. OsteoDura™ features Calcium from Aquamin® TG Sea Minerals. Forget about calcium from limestone. My calcium is sourced from red marine algae. Aquamin is a multi-mineral complex which is derived from the red marine algae, Lithothamnion calcareum. It contains 72 trace minerals absorbed from the sea that make the calcium in Aquamin more bioactive than calcium derived from limestone. Unparalleled Bone Support. OsteoDura™ was physician-formulated with the full spectrum of calcium + critical cofactors needed for comprehensive bone support. Only the highest quality vitamins and minerals made the cut for this cutting edge bone health formula.
