Risk Factors
In vegans the risk is very high because none of their natural food sources contain B12. One American study found blood levels below normal in 92 % of vegans, 64 % of lactovegetarians, 47 % of lacto-ovovegetarians [1]. The study applied the old normal values, so in reality a considerably greater proportion may have been deficient.
