Hi, I used to know that B12 defficiency could lead to some degree of memory loss and neurological problems However, also B12 could be of no deficiency at all, since I also read, in another article, that the deposits one have after eating meat for 10 years are enough to keep releasing B12 into the blood system for the rest of the life. Since I'm feeling some changes in my memory lately(just 37...), and have been vegetarian and 60-70% fruitarian for the last 4 years, and my B12 intake is 30% of RDA , I was wondering how this could be affecting me. Is there any truth on this? Appreciate anyone's comment on this. Thank's Helio
