The body requirement for vitamin B12 is very small (2.4 micro grams daily for an adult) and our body stores it. That is why a deficiency in this vitamin appears many years after you have stopped eating animal products.
A deficiency can cause anemia and severe irreversible nerve damage.
An adequate intake in B12 is generally not a problem for vegetarians who eat eggs and dairy products since those foods contain vitamin B12.
However for vegetarians who to not eat animal products vitamin B12 must be a concern. They must rely on supplements.
We used to think that sea vegetables, tempeh and miso were rich in this vitamin but recents studies have shown the contrary.
