Are Vitamin C Supplements Effective?

Vitamin C is an essential nutrient that the body cannot produce on its own. It is found in many fruits and vegetables, but some people may not get enough vitamin C from their diet. Vitamin C supplements can help to ensure that you are getting enough of this important nutrient.

There is some evidence that vitamin C supplements can help to prevent or shorten the duration of the common cold. However, other studies have not found this benefit. Vitamin C supplements may also be helpful for people who smoke or who are exposed to high levels of pollution.

Vitamin C is also important for wound healing and for maintaining healthy immune function. However, it is important to note that taking too much vitamin C can be harmful. The recommended daily intake of vitamin C for adults is 90 milligrams (mg). Taking more than 2,000 mg of vitamin C per day can increase your risk of side effects, such as diarrhea, nausea, and vomiting.

If you are considering taking vitamin C supplements, talk to your doctor first. They can help you determine if you need a supplement and can recommend a safe dosage.
