At 180 mcg, this **Vitamin K2** sits near the top of the clinically studied range for directing calcium into your bones and teeth instead of your arteries — a strong dose for bone density and cardiovascular support. It uses the MK-7 form, which stays in your blood for roughly four days, so a single daily softgel keeps levels steady where the short-acting MK-4 form would need several doses.

The MK-7 here comes from chickpea suspended in MCT oil, which aids absorption since K2 is fat-soluble. It works hand-in-hand with vitamin D — D pulls more calcium into your body and K2 directs where that calcium goes — so you'll get the most out of it paired with a D3 supplement rather than taken alone.

One caution: if you take warfarin or another blood thinner, vitamin K directly counteracts the medication — talk to your doctor before adding it.
