Vitamin B12, also known as cobalamin, is a water-soluble vitamin found in various foods. Despite its presence in many sources, insufficiency and deficiency are relatively common. According to a publication in Healthline, studies have shown that up to 20% of people over the age of 60 in the United States and the United Kingdom are deficient in this Vitamin and this is often due to limited dairy intake, medical conditions, melabsorption or the use of B12 depleting medications. Symptoms of low B12 levels can range from physical issues to psychological manifestations. It plays a crucial role in red blood cell formation, DNA synthesis, and proper nervous system function.
