Product details "Super K Elite"
Health benefits at a glance:

Vitamin K is not just a single vitamin. In fact, there are several different types of vitamin K, which all support different aspects of your health, from arterial health to bone health. Super K Elite delivers an unparalleled variety of vitamin K forms found in nature. 

Coming in clinically studied doses, the Super K Elite formula is crafted and designed to give you the optimum health benefits that the powerful K vitamins provide.

Why it works:

As you age, the arteries can become increasingly calcified. Another natural consequence of aging is also that the bones in the body may grow increasingly brittle. Vitamin K, however, offers a natural approach to countering these health issues. 

The many forms of vitamins known collectively as vitamin K have an impressive ability to both help inhibit calcification of the arteries and support the absorption of calcium into your bones, keeping them strong and healthy [1,2]. That way, K vitamin also supports a healthy calcium balance in your body.

Containing no less than four different kinds of vitamin K in scientifically studied dosages [3], the Super K Elite formula is Life Extension’s® most potent and elegant vitamin K formula to date.

The science behind the product:

The different K vitamin types in the Super K Elite formula have all been studied scientifically:

K2 Vitamins (MK-4, MK-6, MK-7, MK-9)

Menaquinones are a sub-form of the vitamin K2 family. Mostly derived from high-fat foods [4,5], the vitamin K2 forms known as MK-4, MK-6, MK-7 and MK-9 are known for supporting bone, heart and arterial health [6].

The sub-forms of the vitamin K2 family are called menaquinones. Primarily derived from high-fat foods [4,5] vitamin K2, which includes the forms MK-4, MK-6, MK-7 and MK-9, supports bone, heart and arterial health [6].

One eight-year epidemiological study conducted on 16000 women [7] found that MK-9 promotes cardiovascular health.

Moreover, in a clinical study, MK-4 has also been found to promote arterial health and healthy bone density [9, 10] at a dosage of 1500 mcg - the same amount included in this formula [10].

MK-7, or trans-MK-7 has also been shown to help maintain bone strength and arterial flexibility [11, 12]. In one double-blind, placebo-controlled study, 181 mcg of trans-MK-7 promoted bone and cardiovascular health [12, 13]. This dosage of MK-7 is exactly the same as is found in the Super K Elite formula.
