Review: Vitamin K supplement for blood clotting & liver health. - Local stores are not selling plain vitamin K. They are only selling combo Vitamin K3 + Vitamin D2. Vitamin D is produced by our skin if we go outdoors at all. Vitamin K is found in green leafy vegetables. Type MK7 works in the liver & bone marrow. Type MK1 works in the brain. Most Vitamin K supplements are only type MK7. They are small, easy to swallow, no side effects, no stomach upset, & a decent price. The quality appears to be good.
Review: Life Extension Super K - I like Life Extension products. I use the Super as well as other products. The quality is good and I am satisfied with the pricing.

## Features

- Heart & arterial health — Numerous studies show that vitamin K supports heart and arterial health, with higher vitamin K2 intake being correlated with a healthy cardiovascular system.
- Helps maintain calcium balance — Vitamin K helps you incorporate calcium into your bones. As a part of maintaining “calcium balance”, this process helps keep calcium out of your arteries.
- Vitamin K1 + two forms of K2 — It’s hard to get enough vitamin K from your diet. Super K provides vitamin K1 and two forms of bioavailable K2 to help you get enough daily vitamin K!
- Ingredients matter – We use the finest raw ingredients chosen for quality and purity. The majority of our products are non-GMO, gluten-free and manufactured in the USA with globally sourced ingredients, and a Certificate of Analysis is available for each.
- Live your healthiest life - We believe the answers to a healthier life are within reach, and that scientific research is the key to getting us there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.
