Cyanocobalamin is a manufactured version of vitamin B12. It’s used to treat and prevent vitamin B12 deficiency anaemia (when you have low levels of this vitamin in your body). You may develop a vitamin B12 deficiency if your body doesn’t produce enough intrinsic factor or if you don’t eat enough vitamin B12-rich foods ( 37).
An older study indicated that moderate alcohol intake diminished vitamin B12 by 5% among “healthy, well-nourished, postmenopausal women.” Still, multiple studies have also found oral vitamin B12 supplements to be safe and effective ( 33, 34, 35, 36). Vitamin B12 is one of the many vitamins our bodies require to function properly. B12 is known for being a great source of energy, and many people who start taking a B vitamin supplement report an upswing in their moods and energy levels. Vitamin B12 is not made in the human body, so it must be ingested through outside means. People who have absorption issues and those who consume plant based diet exclusively may struggle to ingest enough to prevent deficiency. Age and pregnancy are other factors that can increase the risk of deficiency.

Vitamin B12 is combined with a protein called intrinsic factor in your stomach. This mix of vitamin B12 and intrinsic factor is then absorbed into the body in part of the gut called the distal ileum. Vitamin B12 (cobalamin) is a nutrient that helps to keep the body’s nerve and blood cells healthy. It is found in foods of animal origin including milk, cheese, yoghurt, and eggs. It is also added to some fortified foods such as breakfast cereals. Common causes of vitamin B12 deficiency include infections, malabsorption, medical conditions (Crohn’s disease, pernicious anaemia), gastric resection, and inadequate dietary intake.
Eating foods that are abundant in B12 is a great way to naturally increase your B12 levels. However, once these foods are ingested, the body has to go through a number of processes to actually be able to absorb the B12 from those foods. Vitamin B12 has to undergo metabolism and then be bound by transport proteins such as haptocorrin, intrinsic factor, and transcobalamin II.Beverages, THE COCA-COLA COMPANY, NOS energy drink, Original, grape, loaded cherry, charged citrus, fortified with vitamins B6 and B12 - Vitamin B12
