Vitamins and nutrients

Your body needs vitamins and minerals to work right. They do so many things, like keep your teeth strong and help you see.

There are 13 vitamins that your body needs: A, D, E, K, C and 8 different B vitamins. Vitamins A, D, E and K are fat-soluble, which means they stay in your body until you need them. B vitamins and vitamin C are water-soluble. These types are used by your body right away. You can get all of these vitamins from the food you eat. Also, with the help of sunlight, your skin can make vitamin D. Your own body can also make vitamin K.

Like vitamins, you can get important minerals that your body needs each day from eating food. We need certain minerals, like calcium, in larger amounts, and others, like iron, in very small amounts each day.

You can get the vitamins and minerals that you need by eating fresh fruits, vegetables, grains, dairy products, and meats. These charts show what each vitamin or mineral does in your body and what foods you should eat to get them. Vitamin pills cannot replace eating healthy foods.

Do I need vitamin and mineral supplements? top

Vitamin tablets are sometimes called supplements. A dietary supplement is any product taken by mouth that has a "dietary ingredient." The ingredients in dietary supplements may include vitamins, minerals, herbs, and amino acids, as well as substances such as enzymes, organ tissues, metabolites, extracts or concentrates. Dietary supplements can be found in many forms such as pills, tablets, capsules, liquids or powders. The labels for these products all have to call them dietary supplements.

Steroids are supplements, too, and they can put your health in real danger. Stay away from steroids unless a doctor has given them to you. To learn more, read:

and
Are Steroids Worth the Risk?

Some people need vitamin-mineral supplements to meet their nutritional needs. For example, people who rarely eat dairy products may need a calcium supplement. Supplements of some nutrients, such as vitamin A and selenium, can be harmful if taken in large amounts. It is important to note that many supplements have labels that say they are "all natural." While this may be true, "natural" doesn't necessarily mean safe. Supplement advertisers often make promises about what their products can do for you. While some supplements can be good for your health, many do not live up to their claims for better health – they may actually be harmful to you. Be especially wary of products that say things like: "miraculous cure," "secret ingredient," "ancient remedy," and other impressive sounding claims.

It's also important to know that supplements do not need FDA (Food and Drug Administration) approval to be sold. Unlike prescription or over-the-counter medicines, supplements do not have to undergo review to make sure they are safe or that they work.

It is always important to check with your doctor before taking any supplements. Some supplements may harm you, even if the label says they can improve your health.

Fiber top

There are also other important nutrients you can get in foods. One of them is fiber. Some good sources of fiber are dried beans, oats, barley, wheat bran, whole grains, cereals, seeds, and the skins of many fruits and vegetables. Here are just a few reasons why it’s important to eat foods with fiber:

  • It can help your heart.
  • It can help keep you from getting cancer.
  • It helps you digest food better.

Water top

Water is also essential for a healthy body. It makes up about 2/3 of your body weight…so drink lots of it! For more information on water, check out Water Science for Schools.
