Doctor’s Best Natural Vitamin K2 MK-7 – 100 mcg – 60 Veg Capsules

Bioactive Menaquinone-7 for Bone Strength & Arterial Health

Description

Doctor’s Best Natural Vitamin K2 MK-7 provides a high-quality, naturally fermented form of menaquinone-7 (MK-7) — a highly bioavailable, long-acting form of vitamin K2 derived from Bacillus subtilis natto.
Each vegetable capsule delivers 100 mcg of natural MK-7, designed to support bone mineralisation, arterial flexibility, and healthy calcium metabolism.

Vitamin K2 activates key proteins (osteocalcin and matrix Gla protein) that help guide calcium into bones and away from arteries, supporting skeletal strength and cardiovascular integrity.
