The symptoms of Vitamin B12 deficiency can silently creep in affecting your moods, energy levels, and interest in daily activities. As lethargy takes over, you may find it increasingly difficult to stay motivated. Vitamin B12 is a crucial nutrient that plays an important role in maintaining the health of your nerves and blood cells. The human body doesn't naturally create it, so it's crucial to get sufficient doses of it from red meat, poultry, eggs, dairy, and fish. In the case of vegetarians and vegans, fortified cereals, plant milks, bread, and nutritional yeast can be included in the diet.
Deficiency of Vitamin B12 may affect production of healthy blood cells in absence of which blood and oxygen doesn't reach the vital organs. It is also apparent in the functioning of the brain and nerves.
