Get Some: Fruits

You probably know about oranges, grapefruits, lemons, and limes. But berries rock too -- strawberries, raspberries, blueberries, cranberries. Papaya, kiwi, pineapple, cantaloupe, plums, and watermelon are good sources. Even bananas, apples, and pears have some.

Eat them fresh and raw. Vitamin C breaks down over time when it's heated.

Get Some: Veggies

Think green. Bell peppers are your big C winners. Load up on leafy greens too  -- kale, Swiss chard, collards, plus cabbage, and bok choy. Crunch into broccoli, cauliflower, and Brussels sprouts. Don't forget tomatoes, sweet potatoes, and winter squash.

If you really have to cook your veggies, stick with steaming or microwaving.  These methods tend to keep more of the vitamin's benefits.

Dynamic Duos

 Vitamin C can help other nutrients work better. Put red peppers in your spinach salad. Slip some broccoli in your baked beans. Pair up strawberries with your oatmeal.

Prevent a Cold? Nope

Your immune system does need vitamin C to work right. But extra won't help you avoid a cold. It may make it go away faster or not feel so bad. That is if you were taking it before you got sick.

Cell Service

Vitamin C helps you get rid of chemicals that cause damage inside your body. It helps offset the effects of pollution, cigarette smoke, sunlight, and radiation and even helps turn food into energy. That could help keep things working better for longer and protect you from diseases, including Alzheimer's and cancer.

Raises Your Sights

The vitamin A in carrots isn't the only thing that's good for your eyes. Vitamin C might slow age-related macular degeneration (AMD), but it won't prevent the disease. C may also cut your risk of cataracts.

Vitamin C vs. the Big C

Very high doses, especially through an IV, may slow the growth and spread of cancer cells. In some case it can help chemotherapy and radiation work better. It may help you feel better and have fewer side effects, too. But be careful. It can also make treatments less effective. Check with your doctor to see if it makes sense for you.

Up in Smoke

When you smoke, you'll have lower levels of vitamin C in your body. Try to get a little extra  every day to make up for it.

People who are around smokers are also affected and could use more vitamin C, too.

How Much?

Most people who eat a variety of vegetables and fruits daily get more than enough vitamin C from their diet.

If you want to take a supplement, look for the inexpensive ascorbic acid form. Check with your doctor about how much is right for you.
