Overview
Overview
For 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 lacto-vegetarians, and 47% of lacto-ovo vegetarians.[1] The study applied the old normal values, so in reality a considerably greater proportion may have been deficient.
