Vitamin B12 or folate deficiency anaemia

A deficiency in vitamin B12 or B9, also known as folate, can lead to anaemia, which occurs when the body produces oversized red blood cells that do not work effectively. Red blood cells are responsible for transporting oxygen throughout the body, aided by a protein called haemoglobin. Anaemia refers to having either a lower number of red blood cells than usual or a reduced amount of haemoglobin within each red blood cell. Both vitamin B12 and folate play crucial roles in the body, including maintaining a healthy nervous system.
