• A B vitamin complex supplement is often touted to boost energy levels and mood. People who have a B vitamin deficiency may feel a rise in energy levels after using the supplement because the vitamin is directly involved in making healthy blood cells and can correct anemia if present. However, there is no evidence of benefit if people without a deficiency take extra B vitamins.
• People who eat a vegan diet are often told to include Brewer’s or nutritional yeast for its B12 content. However, yeast does not naturally contain this vitamin and will only be present if fortified with it. Be aware that certain brands, but not all, contain B12.
• Nori (purple laver), the dried edible seaweed used to make sushi rolls, is sometimes promoted as a plant source of vitamin B12. It does contain small amounts of active vitamin B12, but the amount varies among types of seaweed, with some containing none. Therefore is not considered a reliable food source.
