Your body needs vitamin B12 and other B vitamins to make energy from the food you eat. These vitamins help boost the iron in your blood by making red blood cells. Some studies suggest B vitamins help produce feel-good brain chemicals that boost mood and stave off depression. But more research is needed to confirm this. If your level of B vitamins gets too low, it may lead to health problems. So, if you’re not sure if your B is up to snuff, talk with your doctor.  A simple blood test can help you find out.

If you eat a plant-based diet, eat foods high in B vitamins like dark, leafy green veggies, peas, and beans.
