NOW Foods Vitamin D3 & K2
by NOW Foods
"The essential D3+K2 duo — 1000 IU D3 with 45mcg K2 (MK-7) for proper calcium direction"
Overview
NOW Foods Vitamin D3 & K2 combines 1000 IU (25mcg) of vitamin D3 with 45mcg of vitamin K2 as MK-7 (menaquinone-7) in a single capsule. This combination is increasingly recognized as essential because vitamin D3 increases calcium absorption, while vitamin K2 directs that calcium to bones and teeth (where you want it) and away from arteries and soft tissues (where you don't). Taking D3 without K2 can potentially lead to arterial calcification over time. NOW's combination provides both at an accessible price point with 120 capsules (4-month supply).
