Low on vitamin b12

Vitamin B12 is a nutrient that helps keep the body's nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 also helps prevent anaemia, that makes people tired and weak. Older adults, those with anaemia or have undergone gastrointestinal surgery, have celiac or Crohn's disease and vegetarians and vegans are prone to Vitamin B12 deficiency. If that's you, have your levels checked by your doctor to determine if and how you should supplement.
