I've been told that I have a vitamin deficiency. What should I take?

Vitamin B12 is essential for your health and can help you feel better, so it's important to make sure you're getting enough of it. You can find it in fortified foods such as breakfast cereals, some fish, and nutritional yeast. If you don't eat these foods regularly, you may need to take a supplement. Talk to your doctor or nutritionist to determine what is best for you.
