How Animals Produce Vitamin B12


    Vitamin B12 is crucial for neurological health and red blood cell formation. Animals obtain it from bacteria in their digestive tracts.

    Vitamin B12 is crucial for neurological health and red blood cell formation. Animals obtain it from bacteria in their digestive tracts.Animals do not actually produce vitamin B12 themselves. Instead, bacteria found in the digestive tracts of animals, particularly in the rumen (the first stomach compartment) of ruminant animals like cows, and in the cecum of non-ruminant animals like chickens, synthesize vitamin B12.

    Bacteria from the Soil Produce B21

    These bacteria are able to produce vitamin B12 as part of their metabolic processes. Animals then absorb the vitamin B12 synthesized by these bacteria into their bodies, mainly through their intestines. Consequently, foods derived from animals, such as meat, dairy, and eggs, contain vitamin B12 due to the presence of these bacteria in their digestive systems.

    For example, in a natural environment, cows consume grass, which contains traces of soil containing B12-producing bacteria. These bacteria then synthesize vitamin B12 in the cow’s digestive system, which is later absorbed and stored in the cow’s tissues, including its muscle (meat) and milk.

    Factory Farmed Animals and B12

    In modern factory farming practices, animals are often raised in confined environments where their natural behaviors and diets are restricted. Consequently, the sources of vitamin B12 for these animals will differ from those in natural or pasture-based farming systems.

    Animals raised in factory farms are typically provided with formulated feeds that are designed to meet their nutritional requirements. These feeds may or may not contain synthetic vitamin B12 supplements to ensure that the animals receive adequate levels of this essential nutrient. Additionally, some factory farms may use methods such as vitamin B12 injections or oral supplements to further supplement the animals’ diets.

    Supplements are Essential

    Animals do not directly produce vitamin B12, but rather obtain it from the bacteria in their digestive tracts, which is then transferred to humans through the consumption of animal-derived products. Factory farmed animals, which account for about 99% of the animals products in our stores, will not make their won B12. So everyone, not just vegans, are unlikely to get the optimal amount of B12 in their diet. Supplementation of B12 is important for all of us.
