Vitamin C is a nutrient your body needs to make blood vessels, cartilage, muscle, and collagen. Vitamin C is also important in the body's healing process.

Vitamin C helps protect your cells from the effects of free radicals. These molecules are produced when your body breaks down food or is exposed to tobacco smoke and radiation from the sun, X-rays, or other sources. Free radicals might be involved in heart disease, cancer, and other illnesses. Vitamin C helps the body to absorb and store iron, which helps prevent other diseases.

You need to get vitamin C from your diet. Vitamin C is found in citrus fruits, berries, potatoes, tomatoes, peppers, Brussels sprouts, broccoli, and spinach. Vitamin C is also available as a pill or supplement typically in the form of capsules or chews. Tablets.

Most people get enough vitamin C from a healthy diet. Vitamin C deficiency is more likely in people who do not eat a variety of foods or who do not get enough exercise.

It is important to remember that taking a vitamin C supplement might not offer the same benefits as consuming antioxidants found in foods.

The recommended daily amount of vitamin C for adults is 90 milligrams for men and 75 milligrams for women.
