The Purported Benefits of Vitamin K2: Should You Take Supplements?
Channel: NutritionFacts.org
Date: 2022-12-05

Our body can make vitamin K2 from the K1 in green leafy vegetables.

To summarize, there is no good evidence that vitamin K has bone, brain, or heart benefits beyond its blood-clotting function. And, even if such evidence arose, we can get all of the vitamin K we need from greens, since there’s no requirement specifically for vitamin K2. Further, if some evidence did arise that there was some unique benefit from K2, our microbiome makes K2 from the K1 in greens. What’s more, even if we had a problem with our microbiome, our own cells can make K1 from K2, just like other animals do. So, the bottom line is: Eat your greens.
