This plant-based **Vitamin D3** and **Vitamin K2** pairing delivers 2,500 IU of D3 and 100 mcg of K2, both squarely within clinical range for bone strength, immune defense, and dental health. The D3 is sourced from lichen rather than animal sources, so it's fully vegan — and at 2,500 IU you're well above the maintenance minimum, in the range many practitioners target to keep blood levels adequate year-round.

These two work as a team: D3 helps you absorb calcium, while K2 directs that calcium into your bones instead of your arteries. The K2 here is the MK-7 form, which stays active in your body for days rather than hours — so a single daily softgel is enough to keep it working, with no need to split doses.

One thing to know before you buy: vitamin K can interfere with blood thinners like warfarin (Coumadin), so clear it with your doctor first if you're on anticoagulants. Otherwise this is an easy fit if you want both vitamins in one vegan softgel, especially through darker winter months when the D3 you'd normally make from sunlight runs low.
