What claim?
>No I'm saying similar to "Vitamin B"
There is no vitamin B. You clearly know this, and are deliberately posting complete nonsense.
>In other words K2 intake was correlated with reduced levels of prostate cancer, and K1 was not
And in the studies that found no such correlation to begin with? Pretending a single study is evidence that there's an entire family of vitamins we know noting about is so incredibly stupid I refuse to believe you are actually doing that.
>it's arrogant to dismiss this them as being functionally equivalent
No, it is arrogant to claim that you know everything and this guy is a total moron because he did a great job of 100% completely and totally covering all vitamins, but you want him to worry about what form of vitamin D he uses based on absolutely no evidence that it matters at all.
