Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a critical role in many bodily functions, including red blood cell formation, nerve function, and DNA synthesis. Despite its importance, vitamin B12 deficiency is relatively common, especially in certain populations, such as the elderly, vegetarians, and individuals with gastrointestinal disorders. Unfortunately, many people ignore the subtle symptoms of this deficiency, leading to potential complications if left untreated. This article will explore the often-overlooked symptoms of vitamin B12 deficiency and why it’s important to pay attention to them.

Understanding Vitamin B12 Deficiency

Vitamin B12 is found primarily in animal products, including meat, dairy, and eggs. This makes individuals who follow a vegan or strict vegetarian diet more susceptible to deficiency. Additionally, certain medical conditions can interfere with vitamin B12 absorption, such as pernicious anemia, Crohn’s disease, and celiac disease. Symptoms of vitamin B12 deficiency can be wide-ranging and varied, and often overlap with other health problems, which can lead to misdiagnosis or underdiagnosis.
