Vitamin D increases calcium absorption from the gut. K2 activates the proteins that direct that calcium into bone and prevent it from depositing in arteries. Without K2, absorbed calcium has no guidance system.
Combined formula with vitamin D3 (cholecalciferol) and vitamin K2 (MK-7). MK-7 is the form with the longest half-life and best bone-specific evidence. Both are fat-soluble and conveniently dosed together.

Coming soonHow to take this pair: Take 2,000-5,000 IU vitamin D3 with 90-200 mcg vitamin K2 (MK-7) together with your fattiest meal of the day. Both are fat-soluble and require dietary fat for absorption. Do not confuse K2 (MK-7) with K1 (phylloquinone), which does not have the same bone-directing effects. K2 can interact with warfarin and blood thinners; consult your doctor.
