There's also the fun little dude called K3. Started as a cheapo synthetic form that causes oxidative liver damage in high doses, turns out your body makes it too when you take other forms of K -- it could be what the body uses to ship Vitamin K pass the blood-brain barrier, but nobody's sure. The damage is still true though. Natural != good, especially when you screw with doses. * * * Oh, B. When all the other subscripts are for Vitamers, there's this one guy that just wants to be different. It's not like we don't have enough letters! Having some similarities does not justify this terrible nomenclature!
