**Vitamin K2** at 100 mcg in the MK-7 form — the version your body retains for days rather than hours, which makes it effective for long-term bone and cardiovascular support at lower doses. This sits right at the bottom of the studied range (100–200 mcg), so you're getting a functional dose for directing calcium into your bones and teeth instead of letting it accumulate in arteries.

The softgel format pairs the vitamin with sunflower seed oil, which helps absorption since K2 is fat-soluble. With 240 softgels in the bottle at one per day, you're looking at an 8-month supply — practical if you plan to take it consistently, which matters for K2 since the bone-density benefits build over months.

If you're specifically targeting bone density or pairing this with a calcium supplement, you may want to take two softgels to reach 200 mcg — the upper end of the clinical range where more of the bone health research sits. At one softgel, you're covered for maintenance but not at the stronger studied dose.
