Vitamin B12, or cobalamin, is essential for red blood cell production, DNA formation, and maintaining a healthy nervous system. A deficiency in this crucial nutrient can lead to serious health problems, including anemia, cardiovascular issues, depression, and vision loss.
Common symptoms also include fatigue, headaches, poor concentration, digestive troubles, and nerve-related issues like numbness or tingling in the limbs. These effects stem from the body’s inability to produce enough healthy blood cells or properly support nerve function without adequate B12.
