Vitamin B12 is an essential nutrient that plays a vital role in maintaining the health of your nervous system and the formation of red blood cells. Despite its importance, a deficiency in vitamin B12 can be surprisingly common, especially among those who follow plant-based diets or have certain medical conditions. This deficiency can sneak up on you, with symptoms that are often mistaken for other health issues.
Recognizing the signs early can help you address the deficiency before it leads to more serious health problems. Here are 12 subtle indicators that you might be lacking in vitamin B12.
12. Persistent Fatigue
Feeling constantly tired despite getting enough sleep? This could be a sign of vitamin B12 deficiency.
