Vitamin D3 + K2 combines two fat-soluble nutrients that work as a partnership. The D3 (cholecalciferol) is the same form your skin produces from sunlight, dosed at 5,000 IU (125 mcg) for people who get little sun exposure. The K2 is the premium all-trans MK-7 isomer derived from fermented natto, with a long half-life for sustained daily activity.

The pairing matters: vitamin D helps your body absorb calcium, while vitamin K2 helps direct that calcium toward bone. Each nutrient is suspended in organic extra-virgin olive oil — a fat carrier that supports absorption of these fat-soluble vitamins — in a small, easy-to-swallow softgel.
