**Vitamin D3** at 5,000 IU paired with **Vitamin K2** as MK-7 — a combination that works because D3 increases calcium absorption while K2 directs that calcium into your bones and teeth instead of letting it build up in your arteries. Both ingredients are dosed within their clinical ranges, and both use premium forms, so you're getting full benefit from a single daily softgel.
The D3 dose sits at the top of the studied range (1,000–5,000 IU/day), making this a strong option if you're correcting a deficiency or get limited sun exposure. K2 at 100 mcg lands at the lower end of the studied range (90–200 mcg) but comfortably above the minimum. The MK-7 form has a long half-life (~96 hours), so it stays active in your body for days — one daily dose is plenty. The softgel format with sunflower oil also supports absorption since both vitamins are fat-soluble.
One caveat: 5,000 IU of D3 exceeds the official tolerable upper limit of 4,000 IU/day. While this dose is widely used and supported by clinical consensus for adults, periodic blood testing is worth considering if you're taking it long-term.
