Vitamin C is essential for immune function, and most people can meet daily needs through food, rather than supplements.

Foods like red bell peppers, kiwi, berries, and leafy greens pack more vitamin C than you might expect while offering extra nutrients you won’t get from a pill.

Supplements may help people with limited diets or absorption issues, but most adults can hit their targets by eating a variety of fruits and vegetables.

Your diet is often the best place to start if you want to get more vitamin C. Experts generally recommend meeting your needs through foods like fruits and vegetables since they provide other beneficial nutrients.

Vitamin C will not completely protect you from germs, but it plays an essential role in your immune health. Most women need at least 75 milligrams (mg) per day, while men need slightly more, at 90 milligrams.

Do You Need a Supplement?

While people can meet their vitamin C needs with food, supplements may be appropriate for some.

“Individuals who have very poor appetites, limited food choices, certain digestive conditions that affect absorption, are pregnant, smoke, or otherwise may struggle to meet the recommended vitamin C needs through food alone could benefit from supplementation,” registered dietitian nutritionist Dani Dominguez, MS, RDN, told Health.

Experts generally recommend consulting a healthcare provider before starting any dietary supplement—vitamin C included.
