Carlson offers a variety of vitamin K products – and I like them all for different reasons. K Complete provides vitamin K1, K2 as MK-4, and K2 as MK-7 in a single soft gel. Our body utilizes all three vitamin K forms to achieve optimal cardiovascular, bone, and blood health. K Complete is a great option to "cover all of our bases" for vitamin K requirements. K Complete provides 500 mcg of vitamin K1, 1.5 mg of MK-4, and 45 mcg of MK-7. For those who want more MK-4 or MK-7, they are offered in various strengths of soft gels and capsules.
Carlson also offers MK-7, with or without vitamin D3, in drop form for adults and children. Many people these days are savvy enough in their supplement regime to take calcium and vitamin D to support bone health, but few realize there's another important nutrient to promote bone and cardiovascular health: K2.
Vitamin D3 plays an important role in promoting healthy calcium absorption and creating bone building proteins. MK-7 then activates these proteins, which help bind calcium to the bone matrix. A healthy intake of MK-7 in our younger years can help build a foundation for optimal bone and heart health.
As you can see, each formulation of vitamin K that Carlson has created is important. Which one is best for you depends on your individual needs. Whichever you choose, remember that they are fat-soluble vitamins, so they're best taken with a meal that includes healthy fats, for the best absorption.
