Friday Favorites: Vitamin K2’s Purported Benefits - Should You Take Supplements?
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.
• There is no requirement specifically for vitamin K2, and we can already get all the vitamin K we need from greens.
• If evidence of some unique benefit from vitamin K2 does arise, our own microbiome already makes K2 from the K1 in greens.
So, the bottom line is: Eat your greens.
