Vitamin K2-7

Vitamin K is a group of similar fat-soluble molecules, the most common being K1 and K2.

Further, Vitamin K2 has two common versions; K2-4 or K2-7. K2-7 is also known as Menaquinone-7 and is a component of dietary supplements.

In general vitamin K has health-beneficial effects in osteoporosis, cardiovascular disease, inflammation, cancer, Alzheimer’s disease, diabetes and peripheral neuropathy. Compared to vitamin K1 (phylloquinone), K2-7 is absorbed more readily and is more bioavailable.

Vitamin K1 is often found in plant-based food, however Vitamin K2 (menaquinones) are often found in animal-based foods. Specifically, MK-7 is primarily synthesized by bacteria.
