It plays an essential role in the production of your red blood cells and DNA, as well as the proper functioning of your nervous system. Vitamin B12 is naturally found in animal foods, including meats, fish, poultry, eggs, and dairy. However, it can also be found in products fortified with B12, such as some varieties of bread and plant-based milk. Unfortunately, B12 deficiency is common, especially in the elderly. You’re at risk of deficiency if you don’t get enough from your diet or aren’t able to absorb enough from the food you eat.
Diet or certain medical conditions may be the cause.
Symptoms are rare but can include fatigue, breathlessness, numbness, poor balance and memory trouble.
Any Affecting Organs:
Anemia or nervous system injury from lower than normal amounts of vitamin B12, Vitamin B12 deficiency may lead to a reduction in healthy red blood cells (anemia). The nervous system may also be affected.
Treatment includes dietary changes, B12 shots or supplements.
