The K2, is, wow. I hope you saw some of Dr. Kate Rheaume-Bleue's youtube videos on it. Relates to mineral transport, the K series is like the usher in the movie theater. Absorption is half the equation, getting the people in the theatre is only half the chore, the other half is to usher them, the minerals to the right seat in the body. Esp. with wrinkles and other aging matters caused by K deficiency but reversible, amazing stuff. She actually and you look alot alike, I thought maybe it was you operating under an alias, very pretty of course. What a smart and informed doctor she is, everybody benefits from what she teaches, I think she also touches on boron in some of her talks. Be well !!
