Product Overview

I recently had the pleasure of trying the Life Extension Super K Vitamin K1 and Two Forms of K2 supplement. I have tried many different supplements in the past, but this one really stands out. It is a great product that provides a potent dose of 2600 mcg of Vitamin K from both K1 and two forms of K2.

Vitamin K helps maintain your body s calcium balance, which affects everything from arterial health to bone density health. However, it can be difficult to get sufficient vitamin K from food alone. Even if you are eating leafy green vegetables, it is hard for your body to absorb this nutrient. Vitamin K2 is found in meat, eggs and cheeses, but some people avoid these foods for health reasons. That is why I was so pleased to find this supplement that provides both MK 4 and MK 7 forms of Vitamin K2 in one capsule.

The Life Extension Super K Vitamin K1 and Two Forms of K2 supplement is made with only the finest raw ingredients with the purity and potency your body deserves. It is non GMO, gluten free, and manufactured in the USA with a Certificate of Analysis available for every product produced. The majority of their products are also third party tested which I appreciate because it gives me peace of mind knowing the product is safe and effective.

I found this supplement to be very easy to swallow due to its small size and shape. I also found it to be very absorbable with no unpleasant aftertaste or side effects. In addition, I think it offers great value for money because you get 2600 mcg of Vitamin K in each capsule!

Overall, I am very impressed with the Life Extension Super K Vitamin K1 and Two Forms of K2 supplement and would highly recommend it to anyone looking for a high quality vitamin k supplement. It is an excellent way to get your daily dose of vitamin k without having to worry about getting enough from food alone or avoiding certain food groups due to dietary restrictions or allergies. Plus, you know you can trust that their ingredients are pure and effective thanks to their third party testing!
