Guinness contains small amounts of vitamin B12, but it's not a significant source of this nutrient. The primary ingredients in Guinness, such as barley and yeast, may contribute trace amounts of B12. However, for those seeking to meet their B12 needs, relying on beer is not advisable, as other food sources like meat, dairy, and fortified products are much richer in this vitamin.
