Understanding Vitamin K-2 and MK-7
Vitamin K is a fat-soluble vitamin that exists in two primary forms: K-1 (phylloquinone) from leafy greens and K-2 (menaquinone) from fermented foods and animal products. K-2 is further divided into subtypes, with MK-7 being the most researched for its extended half-life and superior bioavailability. Unlike MK-4, which requires multiple daily doses, MK-7 remains active in the body longer, making it ideal for once-daily supplementation. NOW Foods uses MenaQ7, a branded MK-7 derived from natto (fermented soya) but processed to be soya-free, ensuring a consistent and potent dose. Vitamin K-2 plays a vital role in calcium metabolism, helping to direct calcium to your bones and away from soft tissues like arteries.
Who Can Benefit from Supplementation?
Individuals concerned with maintaining bone density as they age, those with limited intake of fermented foods (such as natto and sauerkraut), and people seeking to support arterial flexibility may benefit from MK-7. It is particularly useful for postmenopausal women, older adults, and anyone taking vitamin D or calcium supplements – since K-2 helps ensure calcium is used appropriately. If you are on blood-thinning medications such as warfarin, consult your health care provider before adding vitamin K.
How to Uses MK-7 Vitamin K-2
Take one 100 mcg vegan capsule daily with a meal containing fat (e.g., with breakfast or lunch) to optimise absorption. Each bottle provides a 120-day supply. This dosage aligns with research showing efficacy for bone and cardiovascular support.* Store in a cool, dry place.
Key Benefits of MK-7
-
Supports normal blood clotting: Vitamin K contributes to normal blood clotting by activating matrix Gla-protein (MGP), which helps prevent calcium from depositing in arterial walls, promoting flexible, healthy blood vessels.
-
Contributes to normal bone maintenance: K-2 activates osteocalcin, a protein that binds calcium to the bone matrix, helping maintain strong, dense bones.
-
Promotes proper calcium utilisation: By directing calcium to bones and teeth rather than soft tissues, K-2 supports overall mineral balance.
-
Synergistic with vitamin D and magnesium: These nutrients work together to optimise calcium absorption and utilisation.
