Analysis

This supplement provides 180 mcg of Vitamin K2 as MK-7 in each capsule. This is a higher dose than many other maintenance supplements, which can be useful for more intensive heart and bone support. It helps activate the proteins that direct minerals into your bones and keep them out of your soft tissues.

The formula is clean and focused, making it a good fit if you already take other vitamins like D3 separately. It is a high-quality way to support your cardiovascular system and maintain long-term skeletal integrity. Since K2 is fat-soluble, it works best when taken with a meal that includes some healthy fats.
