2. B12

Vitamin B12 is vital to the body for making red blood cells, the synthesis of our DNA, and for proper brain function.  Our body does not need much of this vitamin, but it is absolutely vital. Deficiencies in this are quite common, affecting as much as 15 percent of the population. A deficiency in this vitamin can cause extreme fatigue, constipation, weight loss, anemia, weakness, a tingling in the hands and feet. A severe deficiency can cause confusion, dementia, and sores on the tongue or mouth.

The good news is that B12 is found in almost all animal products including poultry, red meat, fish, eggs, and dairy products. Unfortunately B12 is not found in plants, so vegans need to take care to ensure that they get enough of this vitamin. Look for B12 in fortified breakfast cereals and some nutritional yeast products.
