Vitamin K helps maintain your body’s calcium balance, which affects everything from arterial health to healthy bone density. But it’s hard to get sufficient vitamin K from food. So if you’re trying to maintain bone or arterial health, a vitamin K supplement is a good idea. Super K provides THREE kinds of vitamin K to maximize its health benefits: vitamin K1 and two forms of K2, menaquinone-4 (MK-4) and menaquinone-7 (MK-7). 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.

Strong bones, healthy heart—Vitamin K helps maintain your body’s calcium balance, which affects everything from arterial health to bone density health. But it’s hard to get sufficient vitamin K from food. This formula provides a potent dose of 2600 mcg of vitamin K from both K1 and two forms of K2.
Why you need a vitamin K supplement—Vitamin K1 is found in leafy green vegetables, but it’s hard for your body to absorb this nutrient even if a spinach salad is your go-to lunch.
Vitamin K, hold the cheese—Vitamin K2 is in meat, eggs and cheeses. Many people limit these foods for health reasons, which can make it hard to get enough. And there’s more than one kind of K2 as well: this supplement has MK-4 and MK-7. MK-4 absorbs fast, while MK-7 stays active in your body much longer. Combining the two gives you the benefits of both.
Ingredients matter—Sourced using only the finest raw ingredients with the purity and potency your body deserves. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every product we produce.

Great brand
I did a lot of research when it came to choosing a trusted brand. This brand has been great and it isn’t expensive. I have improved my levels of vitamin K and feel a lot better. I will continue using this product.

Works
Been taking this for years. I highly recommend readying more about K2. This product works and has a good balance for quick, medium, long uptake. I take this daily. It is very important for people that have a lot of calcium build up like bone-spurs.

I did not notice any difference
I wonât be re-ordering these because I donât see any difference in my energy. Maybe it will work for someone else though. Just not for me.

A fix for clumped pills
Like many others, my order arrived (in August) with the pills hopelessly clumped together. I put the bottle in the freezer for 30 minutes then used the handle end of a spoon to hit them in an up and down motion. They broke up and separated perfectly. I had to remove a few clumps and separate them by hand. So donât throw them out or return them before trying this.

Good quality and you can feel it
Good brand and quality and I just hope the prices remain fair and otherwise I will continue to buy this brand and only complaint is those flip tops have to go because they are not a good top seal and probably let air into the product sorry to those who can’t take the time to just easily twist off the lid
