3. Vitamin B12
Vitamin B12 is a tricky nutrient to get when you are on a vegetarian diet. The reason for this is because this vitamin is only found in animal products. There are some fortified soy products and cereals that include this vitamin and it is important that you consume these or take a vitamin B12 supplement to ensure that you are getting this nutrient in your diet. If you do not have enough vitamin B12 in your diet it can lead to blindness and anemia. In addition, lack of vitamin B12 can cause numbness, tingling, and weakness.
Vegetarians and vegans are at risk for a deficiency of this important vitamin. Consuming supplements is one of the best ways to lower the risk of a deficiency. As with anything, it is a good idea to discuss this with your doctor and to make sure that you find a quality supplement to use when you begin a vegetarian or vegan lifestyle.
