What is Vitamin C?
Definition and Overview
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a crucial role in various bodily functions. It is an essential nutrient that the body cannot produce on its own, so it must be obtained from external sources such as foods or supplements. Vitamin C is known for its antioxidant properties and is involved in collagen production, immune system function, and iron absorption.
Water Soluble Vitamin
Vitamin C is classified as a water-soluble vitamin, which means it dissolves in water and is not stored in the body. This characteristic sets it apart from fat-soluble vitamins like vitamin A, D, E, and K, which can be stored in the body’s fatty tissues. As a water-soluble vitamin, vitamin C needs to be consumed regularly to maintain optimal levels in the body.
Ascorbic Acid
Ascorbic acid, or vitamin C, is the natural form of the vitamin found in various fruits and vegetables. However, it is also available as a supplement in the form of tablets, capsules, or powders. The daily intake of vitamin C varies depending on age, gender, and health status, but it is generally recommended to obtain the nutrient through a balanced diet rather than relying solely on supplements.
Role and Importance of Vitamin C
Antioxidant Properties
Vitamin C is a potent antioxidant that helps protect the body against damage caused by harmful molecules called free radicals. These free radicals can lead to oxidative stress, which is associated with chronic diseases such as cancer, heart disease, and diabetes. By neutralizing free radicals, vitamin C helps reduce the risk of developing these diseases and promotes overall health and well-being.
Collagen Production
Collagen is a protein that serves as a building block for connective tissues in the body, including the skin, joints, and blood vessels. Vitamin C plays a crucial role in collagen synthesis, helping to maintain the integrity and strength of these tissues. Adequate intake of vitamin C is essential for healthy skin, joint function, and blood vessel structure.
Immune System Function
Vitamin C is known for its immune-boosting properties. It supports the production and function of various immune cells, such as white blood cells and antibodies, which help fight off infections and pathogens. Vitamin C also enhances the body’s natural defense mechanisms and can help reduce the duration and severity of common cold symptoms.
Iron Absorption
Iron is an essential mineral necessary for the production of red blood cells and oxygen transport throughout the body. However, iron absorption from plant-based sources is relatively low compared to animal-based sources. Vitamin C can enhance iron absorption by converting poorly absorbed iron molecules into a more easily absorbed form. This makes vitamin C-rich foods an excellent addition to vegetarian or vegan diets where iron intake may be a concern.

Vegetables (Bell Peppers, Broccoli, Tomatoes)
Vegetables, particularly colorful ones, are another great source of vitamin C. Bell peppers, especially red and yellow varieties, contain high levels of vitamin C. Broccoli, tomatoes, cauliflower, and leafy greens like spinach and kale are also rich in this important nutrient. Incorporating these vegetables into your meals can help ensure a well-rounded intake of vitamin C and other essential vitamins and minerals.
Supplements
While it is generally recommended to obtain nutrients through a balanced diet, vitamin C supplements can be an option for individuals who have difficulty meeting their daily requirements through food alone. Supplements come in various forms and dosages, so it is important to choose a reputable brand and follow the recommended dosage instructions. However, it is always best to prioritize obtaining nutrients from whole food sources whenever possible.
Recommended Daily Intake of Vitamin C
Age-Related Guidelines
The recommended daily intake of vitamin C varies based on age and gender. For adults, the recommended intake is typically around 75 to 90 milligrams per day. However, pregnant and lactating women require slightly higher amounts of vitamin C to support the growth and development of the fetus and to meet the nutritional needs of breastfeeding.
Pregnancy and Lactation
During pregnancy and lactation, the recommended daily intake of vitamin C increases to 85 to 120 milligrams per day. It is important for pregnant and breastfeeding women to consume sufficient amounts of vitamin C to support their own health as well as the health of their baby.
Smokers
Cigarette smoking increases the body’s demand for vitamin C. Smokers are advised to increase their daily intake of vitamin C by an additional 35 milligrams per day to counteract the oxidative stress caused by smoking.
