How much do you know about B vitamins? Most people know that they're important, and maybe that they can help boost your mood, but they do so much more than that. B vitamins have been linked with lower blood pressure, weight loss, reduced migraines, and prevention of birth defects (to name just a few). Basically, B vitamins are necessary for life.

Take this quiz to see what you know about B vitamins, and what you don't. I learned a lot actually. Experts recommend getting the majority of your B's through a healthy diet, but supplements can also be effective as long as you take a B complex and not just individual B vitamin supplements (unless of course your doctor says differently).
