Vitamin B12 deficiency is more common than people realize, especially in older adults, vegetarians, and those with digestive issues. The tricky part is that early signs are often subtle and easily ignored, but they can affect energy, nerves, and overall health.
Common Signs of Vitamin B12 Deficiency
1. Fatigue and Weakness
- Feeling constantly tired even after enough sleep.
- Low energy for daily activities.
2. Numbness or Tingling
- Pins-and-needles sensation in hands, feet, or legs.

5. Mood Changes
