5 Signs of Vitamin B12 Deficiency

Fatigue and Weakness

Persistent fatigue and weakness, even after adequate rest, can be a sign of vitamin B12 deficiency. This is because B12 plays a crucial role in energy production within the body.

Pale or Jaundiced Skin

A deficiency in vitamin B12 can affect the production of red blood cells, leading to a condition called megaloblastic anemia. This can cause the skin to appear pale or even slightly yellow (jaundiced).

Tingling Sensations or Numbness

Vitamin B12 is essential for maintaining the health of nerve cells. Deficiency can result in peripheral neuropathy, characterized by tingling sensations, numbness, or a pins-and-needles feeling in the hands and feet.

Difficulty in Balance and Coordination

Neurological symptoms such as difficulty in maintaining balance, walking, or coordination can indicate a severe deficiency in vitamin B12. This is because B12 deficiency can affect the spinal cord and brain.

Mood Changes or Cognitive Issues

Vitamin B12 deficiency has been linked to changes in mood, such as depression, irritability, or anxiety. Cognitive symptoms like memory problems, confusion, or difficulty concentrating may also occur.
