New info (to me) about B12

I wrote a post a while ago about my vitamin regimen that I realized was wrong. I still learn something every day about life as a sleever, even now, almost a year out! I was talking to my nutritionist about supplementation the other day. I don't take B12, except what's in my multivitamin, because a.) I can't tolerate the sugar alcohols used to sweeten the sublingual tablets and b.) I know I eat at least the RDA (according to mayoclinic.com,"a day's supply of vitamin B12 can be obtained by eating 1 chicken breast plus 1 hard-boiled egg plus 1 cup plain low-fat yogurt") every day. HOWEVER, she informed me that supplementation is still necessary for sleevers because the creation of "intrinsic factor," required to process B12, is one of the few stomach functions that we sleevers lose most of. I always thought that our bodies absorbed everything we eat, but apparently B12 is an exception! Like I say...learn something new every day! So I guess I'm gonna have to either figure out a way to tolerate the sublingual tablets (I wonder if I would be more tolerant of sugar alcohols now than I was early on...although, to be fair, they've always done a number on my stomach!) or get monthly shots :( Bummer dude.
