Hi Fred, Good to see you back. You mentioned lecithin above. I was wondering how it helped you and/or what kind of benefits do you use it for? I've been almost completely unable to tolerate 'normal' fats -- you know, basic dietary fats -- for years now, and I think it's due to a catch-22. Not enough fats, not enough choline (or lecithin), like from egg yolks for example…and then my poor liver and gallbladder suffer, (not to mention methylation, krebs cycle, fat metabolism), because I'm not getting anywhere near the RDA. Plus, I've been taking l-carnitine, but not eating much fat, so may be lowering choline levels even further. My skin couldn't be any drier, and it's been that way for about 3-4 years now...Does that make sense? Also, does anyone know the difference between taking phosphatidylcholine compared to choline bitartrate?
