More facts about Super K with Advanced K2 Complex

Vitamin K helps maintain your body’s calcium balance, which affects everything from arterial health to bone density. But it’s hard to get sufficient vitamin K from food. So a vitamin K supplement is a good idea … and Super K is the best stand-alone vitamin K supplement we offer.

Bone and arterial health

Vitamin K helps maintain bone density by facilitating calcium transport into bone, and helps promote a healthy calcium balance in your arteries.1 Research has shown that vitamin K is essential for the proper function of a protein called matrix Gla-protein (MGP).2 Without normal MGP, calcium in the blood can bind to the arterial wall and affect your health.3

Clinically studied health benefits
The Rotterdam Heart Study, a large-scale, well-controlled clinical trial that tracked 4,800 subjects for seven years, revealed that people who consume more dietary K2 have healthier cardiovascular systems, compared to people who consume lower amounts.4 
Multiple studies have shown vitamin K’s value to maintaining arterial health,5,6 and in a placebo-controlled trial in nearly 250 post-menopausal women found that vitamin K2 supported healthy bone strength and bone density.7

Vitamin K1 and two different types of K2

The most common form of vitamin K, known as K1, is tightly bound to plant cells in leafy green vegetables. Not only do many people not enjoy these vegetables, but K1 is not easily absorbable.8  In contrast, vitamin K2, which is found in small amounts in cheese, egg yolks, and some meats, is up to 6 times more bioavailable than K1, and remains active in the body for a longer period of time.9,10   

The MK-4 form of K2 is the most rapidly absorbed type of vitamin K. However, it only lasts in the bloodstream for a few hours.11   The MK-7 stays available in your body up to 48 hours, and at much higher levels.9,10   And our MK-7 is made from a unique bio-fermentation process.
