Key Symptoms of Vitamin B12 Deficiency
1. Fatigue and Weakness
-
Feeling tired or low on energy even after adequate rest.
-
Low B12 reduces red blood cell production, leading to anemia.

A pins-and-needles sensation in hands, feet, or legs (peripheral neuropathy).
3. Pale or Jaundiced Skin
-
Lack of B12 can cause pale skin or a slight yellow tint (jaundice).
4. Shortness of Breath and Dizziness

Anemia from B12 deficiency reduces oxygen delivery, causing lightheadedness.

Swollen, inflamed, or reddish tongue.
-
Mouth ulcers may appear frequently.

B12 deficiency is common in older adults, vegetarians, vegans, and people with absorption problems (like Pernicious Anemia).
💡 Tips for Prevention & Management

Eat B12-rich foods: meat, fish, eggs, dairy, fortified cereals.

Consider B12 supplements if dietary intake is low or absorption is impaired.
