Chances are you're not getting enough of some important nutrients -- like these five that get scant attention. You should try to get them from food, but if you think you're falling short, ask your health care provider about supplements.

Iron

The name symbolizes strength. Still, up to three out of four adolescent girls and women of childbearing age don't get enough of this vital mineral, according to the Centers for Disease Control and Prevention. Causes of iron deficiency include menstrual bleeding and iron-poor diets.

Iron is essential to building red blood cells that transport oxygen through your body. It's also important to your immune system and mental faculties.

The amount of iron you need varies widely by age, gender, and circumstances. Your body absorbs iron from beef, chicken, and fish more easily than iron from egg yolk, cereal, dried beans, peas, and dark green leafy vegetables.

Selenium

This antioxidant mineral works with vitamins A, C, and E, as well as with the mineral zinc, to protect cells from damage. Selenium may help us avoid prostate, colon, and lung cancer, according to studies at Harvard University, the University of Arizona, and the U.S. Department of Agriculture.

Meats, seafood, grains, and seeds contain selenium, but the amount in foods varies based on where the food was grown. Selenium occurs naturally in soil and different types of soil contain varying amounts of selenium. As a result, foods grown in high selenium soil will contain more selenium naturally.

You need 55 mcg per day, but don't overdo: More than 400 mcg daily can cause skin inflammation, convulsions, and other problems.

Vitamin D

To get enough vitamin D, head outdoors: Your liver makes this vitamin after your skin absorbs sunlight. With the exception of fish oils and some fatty fish, food offers little natural vitamin D. It's added to milk. Vitamin D helps your body absorb and metabolize calcium, strengthening bones. So getting enough Vitamin D is just as important as getting sufficient amounts of calcium.

A sunscreen of 30 SPF or greater appears to block vitamin D production, she adds. Sunscreen users can absorb vitamin D from milk -- but if you don't drink milk, don't forsake your sunscreen. Ask your doctor what's right for you.

Heed the intake suggestions below. More than 2,000 IU daily can be toxic.

Vitamin K

Vitamin K helps make your blood clot and works with calcium and vitamin D to build strong bones.

Normal bacteria in your digestive system help make vitamin K. To ensure you consume enough vitamin K, eat those green vegetables. Your body also can make vitamin K from eggs, milk, and meat.

Vitamin K can interfere with blood-thinning medications Talk with your doctor if you're on such medication or you're not sure.

Zinc

Zinc’s functions in the body are many and diverse. It is involved in the action of many enzymes. Specific functions in humans are difficult to pinpoint but people who don't get enough zinc are at higher risk for growth failure, dermatitis, birth defects, decreased sperm production, and changes in the immune system.

Zinc has been popular as a supplement, but claims that it shortens colds appear to be unfounded.

You can find zinc in many foods, including red meat, wheat bran, almonds, peanut butter, and tuna. Vegetarians need more zinc than people who eat animal products.
