That's right. That's why I have a page on my site about the foods containing B12.

The fact is, however, that brown rice does contain B vitamins. I became aware of this when I tried chia seeds and got very sick. After that I found a good site which showed that brown rice has B vitamins, while chia seeds do not. For me, chia seeds did not work at all well, and I think that may be because I have some sort of celiac problem... which may be common in people with low B12 since the one doctor I saw and complained to about my diarrhea said it was just something people with low B12 had to learn to live with. But, once I went to eating brown rice instead of potatoes, the diarrhea went away, which was sooooo a miracle.
