Vitamin B12 Deficiency: Symptoms and Foods
Introduction
Vitamin B12 is an essential nutrient that helps keep your nerves healthy, supports red blood cell production, and plays an important role in DNA formation. A lack of Vitamin B12 can lead to fatigue, weakness, nerve problems, and anemia. Since the body cannot produce Vitamin B12 on its own, it must be obtained through food or supplements when needed.
