In trying to get an firm understanding of PS, PC, PI, lecithin, acetylcholine, choline, myoinositol, I've been pursuing my own little research campaign, only to walk away far more confused than where I started. It has been difficult finding resources that take a "see the forest for the trees" approach. I learn best when I get a basic understanding of the big picture before narrowing in on each item. Can anyone provide an overview? Or do you know of any resources that do? Earlier this year I started taking Yasko's PS complex and I'm just wondering if it is the best supplement for my needs, which are related to mitochondria, fatty liver & fertility. Thank you!!
