Vitamin B12 has been a hot topic in the nutrition community for the past few years, due to the decrease in individuals consuming traditional diets, and the shift towards vegetarian, vegan and entotarian diets. Today, we have decided to tackle this common topic and teach you 3 things you need to know about this famous B vitamin!
What is vitamin B12 and why is it so important?
Vitamin B12, also known as cobalamin, is an essential water-soluble B vitamin, meaning the body cannot synthesize it on its own and it must be obtained through the diet. Vitamin B12 is a vital co-enzyme that participates in maintaining the body’s homeostasis and plays a crucial role in blood and neurological functioning. Individuals with inadequate vitamin B12 intake are at risk of a deficiency in cobalamin, which may lead to megaloblastic anemia, reduced neurological functioning, and rapid decline of cognitive function. Common symptoms for individuals with a B12 deficiency include low energy, reduced ability to exercise, fatigue, shortness of breath, and more. Thus, it is very important for ultra endurance athletes to pay attention to their B12 vitamin intake.
What foods are rich in vitamin B12?
Vitamin B12 synthesis is limited to anaerobic bacteria i.e. bacteria that do not require oxygen to live. Animals ingest these bacteria, which then remain in their gastrointestinal tracts and become part of their ruminal and intestinal microflora. Therefore, cobalamin is mainly prevalent in animal-based food products such as meat, poultry, fish, seafood, eggs, cheese, and milk. However, the increase in individuals adhering to a vegetarian or vegan diet has led to an increase in the availability of cobalamin supplements as well as food fortification. For instance, soy milk, meatless burger patties, soy-based meat alternatives, etc. are all examples of foods that are commonly fortified with vitamin B12.
