K2 FAQs
Common questions about this ingredient in skincare.
What is Vitamin K2?
Vitamin K2 is a family of menaquinones, including MK-4 and MK-7, that perform vitamin-K functions in the body.
How does K2 support bones?
Vitamin K is needed to activate osteocalcin and other proteins involved in bone mineralization, but supplement trials have produced mixed outcomes.
Does K2 direct Calcium only into bones?
That phrase oversimplifies the science. K-dependent proteins help regulate calcium binding, but K2 does not act as a simple calcium-routing switch.
What is the difference between MK-4 and MK-7?
They are different menaquinones with different sources, doses, and pharmacokinetics; MK-7 generally remains in circulation longer.
Can I take K2 with Vitamin D3 and Calcium?
These nutrients are often combined, but the appropriate amounts depend on diet, health, and medications. Follow professional and label guidance.
Who should not take K2 without medical advice?
Anyone taking warfarin or another vitamin-K antagonist must consult the prescribing clinician and maintain consistent vitamin K intake.
