What is a reliable source of vitamin B12 for a vegan?

Question

Quizplus · Accepted Answer

Fortified soy milk is a reliable source of vitamin B12 for vegans as it is commonly fortified with this vitamin. Seaweed, fermented soy, firm-style tofu, and fortified margarine may contain some vitamin B12, but it may be in an inactive form that the body cannot absorb efficiently, making it an unreliable source. As vitamin B12 is mainly found in animal products, a vegan diet may not provide enough of this vitamin without fortified foods or supplements.
