More facts about Super K

Super K provides THREE kinds of vitamin K: vitamin K1 and two forms of K2, menaquinone-4 (MK-4) and menaquinone-7 (MK-7). So taking Super K every day is a good way to make sure you’re getting enough of this essential nutrient for bone and vascular heath.

Bone and arterial health

Vitamin K helps maintain bone density by facilitating the incorporation of calcium into your bones.¹ Vitamin K also supports normal function of a protein called matrix Gla-protein (MGP).² MGP helps regulate how calcium interacts with your arterial walls.³ So in addition to facilitating calcium incorporation into bone, vitamin K helps promote a healthy calcium balance in your arteries as well.

Clinically studied health benefits

The Rotterdam Heart Study is a large-scale clinical study. One report from this study involved 4,800 subjects tracked for at least seven years. It revealed that people who consume more dietary K2 have healthier cardiovascular systems compared with people who consume lower amounts.⁴

Multiple studies have shown vitamin K’s value to maintaining arterial health.^5-8 And vitamin K supplementation is a good way to support healthy bone strength and bone density.⁹

Vitamin K1

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 vitamin K from these sources may be poorly absorbed.¹⁰ 

Vitamin K2

In contrast, vitamin K2, which is found in small amounts in cheese, egg yolks and some meats, has been found to be up to eight times more bioavailable than K1 and to remain active in the body for a longer period of time.¹¹  

The MK-4 form of K2 has been shown to be rapidly absorbed, but to only last in the bloodstream for a short time.¹⁰ MK-7, on the other hand, was demonstrated to stay available in the body for up to 48 hours and at much higher levels.¹² And our MK-7 is made from an innovative bio-fermentation process.
