The nutrient people often overlook 👀 and why it’s in Good Green Vitality

A closer look at vitamin K₂ and the MK-7 form.

The vitamin many people overlook and why MK-7 is included in Good Green Vitality

Vitamin K₂ is distinct from vitamin K₁. While they are related, each form plays its own role in normal human physiology.*

Vitamin K₂ (specifically the MK-7 form) is often highlighted in nutrition research and supplement formulation because of how it behaves in the body and how it can be reliably measured.

Here’s a closer look at why MK-7 is used.

What makes vitamin K₂ (MK-7) interesting?

Vitamin K₂ (MK-7) occurs naturally in small amounts in certain fermented foods, such as natto and kimchi. It continues to be an area of scientific interest because:

Different forms of vitamin K behave differently in the body
MK-7 remains in the body longer than vitamin K₁
Its naturally occurring food sources are relatively uncommon in many everyday diets

For these reasons, MK-7 is the most widely studied and commonly used form of vitamin K₂ in nutritional supplements.

What research has looked at

Scientific research has examined how MK-7 is involved with vitamin-K-dependent proteins that play a role in normal bone and vascular processes.*

These studies focus on nutrient utilisation and physiological function, rather than therapeutic outcomes.

Why MK-7 is included in Good Green Vitality

In the body, vitamin K₂ (MK-7) contributes to:

Normal bone maintenance*
Normal blood clotting*
A broader intake of fat-soluble nutrients
A form of vitamin K₂ that can be accurately measured and standardised

Including MK-7 helps add nutritional variety that everyday meals may not always provide.
