Signs of Vitamin B12 Deficiency That Are Often Ignored

Introduction

Vitamin B12 is essential for healthy nerve function, red blood cell production, and DNA synthesis. Yet, many people are unaware they are deficient until symptoms become severe. Early detection is key to preventing long-term health issues. Let’s explore the common—but often overlooked—signs of vitamin B12 deficiency and how to address them.

Signs You Might Be Deficient in Vitamin B12

Fatigue and Weakness
A lack of B12 can reduce red blood cell production, limiting oxygen transport and causing persistent tiredness, even with adequate sleep.

Pale or Jaundiced Skin
B12 deficiency can affect red blood cells, leading to paleness or a slight yellowing of the skin and eyes.

Tingling or Numbness
Deficiency can damage nerves, causing tingling, numbness, or a “pins and needles” sensation, often in hands and feet.
