Vitamin B12, scientifically referred to as cobalamin, is a vital nutrient with a pivotal role in numerous bodily functions. It is necessary for maintaining a healthy nervous system, producing DNA, and forming red blood cells. Sometimes, individuals may experience vitamin B12 deficiency due to dietary restrictions, medical conditions, or absorption issues. In such cases, healthcare providers may recommend Vitamin B12 injections as an effective way to replenish the body’s B12 levels.
