The objective of this study is to evaluate the prevalence of vitamin B12 supplementation in vegetarians at the Regional University of Blumenau (FURB), since vitamin B12 is synthesized by bacteria and found in animal products, isn’t present in adequate quantities in products of plant origin, since the plants don’t need vitamin B12. The research was carried out with vegetarians FURB students. A questionnaire with 13 questions was applied by Google form and sent by e-mail, for 20 people, with questions regarding vitamin B12 supplementation and vegetarianism.
