Vitamin C, also known as ascorbic acid, is a vital water-soluble nutrient renowned for its powerful antioxidant, immune-boosting, and tissue-repairing properties. Since the human body cannot produce or store it, daily intake through diet is essential for maintaining optimal health.
Vitamin A: Essential for Vision, Immunity, and Cellular Health
One of vitamin C’s most important roles is in the production of collagen, a protein necessary for the health and repair of skin, blood vessels, bones, and connective tissues. This makes it crucial for wound healing and maintaining skin elasticity. It also supports iron absorption, especially non-heme iron from plant sources, making it important in preventing iron-deficiency anemia.
Vitamin C is widely known for enhancing immune function. It stimulates the production and function of white blood cells (lymphocytes and phagocytes), helping the body fend off infections. Additionally, as a potent antioxidant, vitamin C neutralizes free radicals, reducing oxidative stress and lowering the risk of chronic diseases such as cardiovascular disease and certain cancers.
A deficiency in vitamin C can lead to scurvy, a serious condition marked by fatigue, gum disease, joint pain, and poor wound healing. While rare in developed countries, mild deficiencies can still impair immunity and slow recovery from illnesses.
Excellent food sources of vitamin C include citrus fruits (oranges, lemons, grapefruits), berries, kiwis, bell peppers, broccoli, and tomatoes. Since it is water-soluble and sensitive to heat, cooking can reduce its content, so raw or lightly cooked foods are best.
The recommended daily intake for adults is around 75–90 mg, with higher needs during illness, stress, or smoking. While supplements are available, a balanced diet rich in fruits and vegetables usually provides sufficient amounts to maintain strong immunity, radiant skin, and overall well-being.
