WHAT IS IT?

Super K with Advanced K2 Complex is Vitamin K1 and K2. Each capsule contains Vitamin K1 9 mg, Vitamin K2 1 mg (as menaquinone-4 and Nutri-K™ menaquinone-7,) Medium Chain Triglycerides (MCT oil) 215 mg, Ascorbyl palmitate 25 mg. Other ingredients are gelatin, glycerin, beeswax, carob color.

There are three kinds of Vitamin K: K1 comes from plants and is converted by the body into K2. K2 is made by intestinal bacteria and is the therapeutic kind. K3 is toxic as it generates free radicals. Like Vitamin D, Vitamin K is actually more like a hormone than a vitamin.

WHAT DOES IT DO?

According to the manufacturer:

"An abundance of human clinical data reveals that vitamin K plays a critical role in maintaining healthy bone density by facilitating the transport of calcium from the bloodstream into the bone. Few doctors understand that vitamin K is also required by calcium-regulating proteins in the arteries. without adequate vitamin K, calcium in the blood can bind to the arterial wall resulting in calcification. As people age, even a subclinical vitamin K deficiency can pose risks to the vascular system.

Vitamin K1 is obtained in the diet primarily from dark leafy vegetables (lettuce, spinach, and broccoli). Unfortunately, vitamin K1 is tightly bound to the chlorophyll in green plants, thus, aging humans are not always able to benefit from ingested K1-containing plants. While vitamin K1 is not absorbed particularly well from food, it is absorbed from supplements, provided that the supplements are taken with meals.

Vitamin K2 is found in only small quantities in the diet, primarily in dairy products. Human studies show that vitamin K2 is absorbed up to ten times more than K1. Vitamin K2 remains biologically active in the body far longer than K1. For instances, K1 is rapidly cleared by the liver within 8 hours, whereas measurable levels of K2 have been detected 72 hours after ingestion.

Super K provides vitamin K1 and a new biologically active form of vitamin K2 known as menaquinone-7. The menaquinone-7 form of vitamin K is not metabolized quickly by the liver, thereby making it available to provide a more consistent supply of vitamin K to the body."
 

CAUTIONS

Despite being a fat-soluble vitamin, it is not stored in the body and is not toxic even at high doses. Naturally, people who take anticoagulants like warfarin or heparin should not take it. Too much Vitamin K will not cause the blood to clot. In fact, it helps prevent clotting by inhibiting platelet aggregation. Ironically enough, people who take anticoagulants long term tend to suffer from osteoporosis, accelerated atherosclerosis, and hemorrhage because their medication blocks Vitamin K. One study showed that taking anticoagulants long term doubles the risk of stroke!
