Why we chose this...

Most of us think of Calcium when we think of bone health - but the key to healthy bones is a balance of several vitamins. One of those is Vitamin K, which flies under the radar, but it's crucial to supporting strong bones. It pairs with magnesium to help keep calcium locked into your bones and out of your blood vessels and other soft tissues. 3-K Complete is one of the best formulations on the market - it contains 3 clinically studied forms of Vitamin K.
