Vitamin C is an essential nutrient that your body needs to stay healthy. It helps your body use carbohydrates, fats, and proteins, and it also acts as an antioxidant. Citrus fruits, tomatoes and tomato juice, potatoes, and a variety of other fruits and vegetables are all great sources of vitamin C. Vitamin C is also available in supplement form, usually in the form of capsules or chewable tablets.
Albert Szent-Györgyi discovered the chemical ascorbic acid, also known as vitamin C, in the 1930s. His discovery allowed the body to efficiently use carbohydrates, fats, and proteins. Vitamin C is vital for the immune system, connective tissue, and the health of the heart and blood vessels. Eating plenty of cruciferous vegetables rich in vitamin C has been linked to a reduced risk of cancer.
Smokers need 35 milligrams (mg) more vitamin C per day than non-smokers because smoking increases oxidative stress. A medium-sized kiwi provides 62% of the recommended daily amount of vitamin C. Vitamin C is found in citrus fruits and juices, red and green peppers, kiwi, strawberries, broccoli, cauliflower, Brussels sprouts, cabbage, spinach, and potatoes. If you take vitamin C for its antioxidant properties, keep in mind that the supplement may not offer the same benefits as natural antioxidants in foods.
Overconsumption is more common among people who take vitamin C supplements; it is rare among people who eat large amounts of foods that contain vitamin C.
