This product pairs **Vitamin D3** (5,000 IU) with **Vitamin K2** as MK-7 (100 mcg) — two fat-soluble vitamins that work together. D3 increases your calcium absorption, while K2 directs that calcium into your bones and teeth instead of letting it accumulate in your arteries. Both are dosed within their well-studied clinical ranges.

The forms are premium across the board. D3 is cholecalciferol sourced from lichen (fully plant-based), the same form your skin produces from sunlight and significantly more effective than D2. K2 is MK-7, the long-acting form that stays active in your body for roughly 96 hours. The softgel contains coconut MCT oil and olive oil as fat-based carriers that improve absorption of both vitamins.

At 5,000 IU, the D3 dose exceeds the official upper limit (4,000 IU), though it's widely used in clinical research for people with low levels. If you haven't had your vitamin D blood level tested, checking before committing to this dose is a practical step. The 100 mcg K2 is right in the effective range for bone and cardiovascular support.
