1. Functions: Vitamin C is an essential nutrient that the human body needs to perform several functions. It is necessary for the growth and repair of tissues in the body, including bones, skin and blood vessels. It also helps the body produce collagen, which is necessary for healthy skin, hair and nails. Additionally, vitamin C is a powerful antioxidant that helps protect the body from damage caused by free radicals.

3. Recommended Daily Intake: The recommended daily intake of vitamin C varies based on age and sex. In adults, the recommended daily intake ranges from 65-90 mg per day, depending on sex. Smokers require higher levels of vitamin C due to the harmful effects of smoking and the recommended daily intake for smokers is 100-120 mg per day.
4. Deficiency: A deficiency in vitamin C can lead to a condition known as scurvy, which causes symptoms such as fatigue, joint pain and bleeding gums. Although scurvy is rare in developed countries, a mild deficiency in vitamin C can lead to symptoms such as poor wound healing, dry and splitting hair and a weakened immune system.
5. Health Benefits: Vitamin C has been associated with several health benefits, including reducing the risk of chronic diseases such as heart disease and cancer. It may also help boost the immune system, improve skin health and reduce the risk of age-related macular degeneration.
