How Do Vitamins Work?
Contributed by Dr. Jeffrey Blumberg
While vitamins might not take the spotlight as the crew chief, the various jobs our bodies need to do would not be possible without their help.
Ideally, we get the vitamins we need from the foods we eat.2 In the body, proteins, carbohydrates, and fats combine chemically with other substances to provide energy and build body tissue. Enzymes produced from specific vitamins, initiate or accelerate these chemical reactions.3, 4 For example, the B vitamins help with the formation of active enzymes that help transfer energy from the food we ingest to the body.3

When to Take a Multivitamin
While dietary supplements should never be a substitute for a healthy diet, a typical multivitamin supplement with minerals can help substantially to make up any shortfalls between required amounts of nutrients and the usual amounts most of us get in our daily lives.
If you’re not sure whether you’re getting all the essential vitamins you need every day from your diet, consult with a nutritionist or your doctor, and consider the added benefits of taking a daily multivitamin.
