What Sets MK-7 Apart from Other Vitamin K Forms?
Vitamin K comes in two main forms: K1 (phylloquinone) from leafy greens and K2 (menaquinones) from animal products and fermented foods. Amongst the K2 group, MK-7 stands out due to its superior bioavailability and longer half-life, allowing for steady blood levels with once-daily intake. In contrast, MK-4 has a much shorter duration and requires multiple doses throughout the day.
The MK-7 in Swanson supplements is sourced from natto, a traditional Japanese fermented soybean food renowned for its high K2 content. Each soft gel capsule provides a potent 200 mcg dose, optimised to support the body's calcium metabolism efficiently.
Why Your Body Needs Vitamin K2
Vitamin K2, specifically menaquinone-7 (MK-7), plays a vital role in directing calcium to where it is needed most—your bones and teeth—while helping to prevent calcium buildup in soft tissues like arteries. This distinction makes K2 essential for maintaining both skeletal strength and cardiovascular wellness. Swanson High Potency Vitamin K2 delivers 200 mcg of MK-7 from traditional Japanese natto, a fermented soybean source known for its high K2 content.
As we age, our natural production of vitamin K2 declines, and dietary intake alone may not be sufficient to meet daily needs. Supplementing with a bio-available form like MK-7 can help fill this gap, especially for adults over 50 who are more focused on bone density and heart function.
How Vitamin K2 Supports Normal Bones and Blood Clotting
-
Bone health: Vitamin K2 activates osteocalcin, a protein that binds calcium to the bone matrix, contributing to bone density and strength. This may help reduce the risk of age-related bone issues.
-
Cardiovascular function: K2 also activates matrix Gla-protein, which inhibits calcium deposition in arterial walls. By keeping arteries flexible, K2 helps maintain normal blood flow and cardiovascular function.
-
Calcium regulation: Proper calcium distribution is critical. K2 ensures that calcium absorbed from food or supplements goes to bones rather than soft tissues.
These actions make vitamin K2 an invaluable partner to vitamin D and magnesium in a comprehensive bone and heart health regimen.
Who May Benefit from Vitamin K2 Supplementation?
While anyone can benefit from adequate vitamin K2, certain groups may find supplementation especially helpful:
- Adults over 50, as bone remodelling and arterial health become greater concerns
- Individuals with limited dietary intake of fermented foods or animal products
- People taking vitamin D or calcium supplements, as these increase the need for K2 to direct calcium appropriately
- Those concerned about maintaining healthy circulation
How to Uses Swanson Vitamin K2 for Best Results

Safety and Considerations
Vitamin K2 is generally well tolerated.
