Probably didn't supplement with B12... when I went to college, most of the PETA vegans were really nasty libs. However, I work with a lot of rastafarian vegans and their children are brilliant and very sharp minded with beautiful skin. Most all are homeschooled where they can monitor their lifestyle and diet too.
This is a term I don't know. Could you share a bit more? Tx.
B-12 is the missing ingredient...
