Mecofol Tablet is a vitamin B12 supplement. Red blood cell formation, as well as the brain and nerves, depend on vitamin B12. A deficiency of vitamin B12 causes pernicious anemia, a condition in which your body lacks enough red blood cells to transport oxygen throughout your body. Your body will make fewer red blood cells and may result in anemia if you do not get enough vitamin B12 from your diet (due to inadequate nutrition or poor absorption of the mineral). A dietary supplement called Mecofol Tablet is used to treat or prevent low vitamin B12 levels in the body. Anemia can result from a lack of either of them, as they are both necessary for the synthesis of red blood cells. It can increase your red blood cell count and lessen anemia symptoms like weakness and fatigue. For optimal effects, take it for the precise amount of time and dosage that your doctor has advised.
