Question: I have been looking like crazy for a B vitamin supplement that will give me a ton of energy, but there are so many at so many prices. It would be nice to have the field narrowed for those of us who don't want to spend lots of money.

Answer: You're probably already getting enough B vitamins from the foods you eat, as long as you're eating a typical diet, since they're found in a wide variety of foods. If you're worried that your diet may be deficient, any inexpensive B-complex supplement will give you all the B vitamins you need.

If you're looking for a B-complex vitamin supplement to make you feel more alert or more motivated, you're probably going to be disappointed. Your body needs the B vitamins for many different reasons, including metabolizing food to energy and healthy brain function, but the B vitamins don't work as fuel, and they don't act like caffeine.

In that case, you're looking for an energy supplement. Typically, these supplements come in the form of tablets or liquids and are easy to find in any store, usually marketed to young people. They contain small amounts of B vitamins and other ingredients like amino acids or herbs, but the main active ingredient is caffeine. Some contain lots of sugar as well.

Dietary supplements may help to ensure that you'll get all the vitamins and minerals you need, but they won't counteract the effects of eating a poor diet. If you're feeling tired and sluggish, you may need to look at foods you eat every day (and you should speak to a health care provider). Be sure to get the right number of calories; avoid excess fats, sugars and sodium; and eat lots of fiber-rich fruits, vegetables and whole grains every day, along with healthy fats, such as omega-3 fatty acids found in fish, flax seeds and canola oil. If you decide you need to take supplements, I've got tips for choosing high quality dietary supplements.
