Supplements can help you feel better faster.

Myth. Taking a daily multivitamin is probably a good idea to stay healthy if you eat poorly. But taking megadoses of a single vitamin or supplement has not been proven to help the immune system.

Kids need supplements to build a healthy immune system.

Myth. Vitamins and minerals matter for kids too, but they should get them from eating nutritious foods. If your child is a picky eater, a vegetarian, or a vegan, your doctor may recommend a supplement. Remember: Though you can buy children’s vitamins over-the-counter, they are still drugs. Taken excessively, they can be toxic.

Sucking your baby’s pacifier can make him less likely to develop allergies.

Fact. Do you cringe when you see a parent pick up a baby’s pacifier and suck it before returning it to the baby’s mouth? Don't. A recent study found that parents who suck their infant’s pacifier may lower the baby’s risk of having allergies. The thought is that germs transferred to the infant from the parent’s saliva will kick-start the baby's immune system. 

Exercise has no effect on the immune system.

Myth. While there’s no direct link between moderate exercise and keeping the average person’s immune system humming, there are lots of benefits to working out. Among other things, it lowers blood pressure, keeps body weight under control, and can protect you from certain diseases. So get moving.
