For bone health and calcium regulation, this pairs **Vitamin D3** at 5,000 IU (125mcg) with **Vitamin K2** as MK-7 at 100mcg — both at the top of their respective clinical ranges. D3 at this dose is well-supported for raising and maintaining your blood levels of 25(OH)D, and K2 as MK-7 directs calcium into your bones instead of your arteries, with a long half-life that keeps working between doses.

The D3 here is listed as VEGADELIGHT, a plant-based cholecalciferol sourced from lichen rather than sheep's wool lanolin, making this suitable if you follow a vegan diet. The softgel format with coconut and olive oil supports absorption since both D3 and K2 are fat-soluble.

At 5,000 IU daily, this exceeds the conservative RDA of 600 IU but aligns with current clinical consensus for adults with low sun exposure or existing deficiency. If you're already getting significant vitamin D from other supplements or fortified foods, you should monitor your blood levels to avoid overshooting.
