Most people believe that the only cause of anemia is iron deficiency, but sometimes, anemia can be a sign of low levels of vitamin B12.

A deficiency in this vitamin leads to numerous other symptoms as well, like muscle weakness, low energy, appetite loss, weight loss, feeling breathless, poor vision, mouth sores, menstrual disorders, and more.

These are the most common 3 signs of vitamin B12 deficiency:

  • Nausea
  • Fatigue
  • Anemia
  • Digestive issues
  • Mental confusion
  • Nerve problems (numbness, tingling, trouble walking)
  • Skin infections
  • Weakness
  • Skin infections

A deficiency in vitamin B12 can also cause central nervous system disorders like dementia and Alzheimer’s.  Researchers have also found that vitamin B supplements can be of great help in the treatment of psychiatric conditions, like schizophrenia.

  • Adults and teenagers: 2.4 micrograms (mcg) per day
  • Children between 9 and 13 years old: 1.8 mcg per day
  • Children between 4 and 8 years old: 1.2 mcg per day
  • Toddlers between 1 and 3 years old: 0.9 mcg per day
