4. Some people, especially older adults, have trouble absorbing Vitamin B12 from food.
5. A deficiency in Vitamin B12 can lead to anemia, a condition where the body does not have enough healthy red blood cells.

Symptoms of Vitamin B12 Deficiency

Recognizing the symptoms of Vitamin B12 deficiency can help in early diagnosis and treatment. Here are some common signs to watch for.

6. Fatigue is a common symptom because the body lacks enough red blood cells to carry oxygen.
