This NOW product provides a solid dose of highly bioavailable Calcium Hydroxyapatite, a natural and effective form for bone health. Its main limitation is the absence of crucial Vitamin D3 and K2, which are essential for optimal calcium absorption and utilization.
NOW's Calcium Hydroxyapatite Caps offer a good 500mg dose of calcium per serving in the highly regarded Calcium Hydroxyapatite form, which closely mirrors the mineral structure of human bone and is known for excellent bioavailability. This form also naturally includes phosphorus, supporting comprehensive bone mineralization. With 5667 reviews, it's a popular and well-received product. However, similar to many standalone calcium supplements, it lacks critical co-factors such as Vitamin D3 and Vitamin K2. These vitamins are vital for ensuring calcium is properly absorbed from the gut and subsequently directed into the bones, preventing undesirable calcification in soft tissues like arteries. Without these synergistic nutrients, the product's full potential for bone and cardiovascular health may not be realized, requiring users to supplement these vitamins separately.
