For which group is Vitamin B12 supplementation or fortified food consumption deemed essential to prevent neurological damage?

Answer

Vegans, because they lack the easy B12 sources available to vegetarians.

Vegans must proactively use Vitamin B12 supplementation or fortified foods because they exclude all animal products, unlike lacto-ovo vegetarians who can obtain it through dairy and eggs.
