For directing calcium into your bones and away from your arteries, this delivers 100mcg of **Vitamin K2** in the MK-7 form — the version with a long half-life (~96 hours) that stays active in your body far longer than MK-4. At 100mcg, you're squarely within the 90–200mcg clinical range studied for bone and cardiovascular health.
The MK-7 is sourced from natto (fermented soybean), which is the most common and well-researched origin for this form. One capsule daily with a meal is all you need, and 120 capsules gives you a four-month supply — solid value for consistent use.
If you're taking blood thinners like warfarin, vitamin K2 directly affects clotting factors and you should consult your healthcare provider before using this product. For everyone else, this is a well-dosed, single-purpose K2 supplement that pairs naturally with vitamin D3.
