Vitamin C

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a critical role in many physiological processes in the human body. Unlike some other animals, humans cannot produce vitamin C on their own and must obtain it from their diet.

Vitamin C is found in many fruits and vegetables, including citrus fruits, strawberries, kiwi, papaya, bell peppers, broccoli, and tomatoes. The recommended daily intake of vitamin C varies by age and gender, but typically ranges from 75 to 120 milligrams per day for adults.

Vitamins C is involved in many physiological processes, including:

1. Immune function: Vitamin C is involved in the production of white blood cells, which are important for fighting infections and disease.
2. Collagen synthesis: Vitamins C plays a critical role in the synthesis of collagen, a protein that is essential for the health of skin, bones, and other tissues in the body.
3. Antioxidant function: Vitamins C is a powerful antioxidant that helps protect cells from damage caused by harmful molecules known as free radicals.
4. Iron absorption: Vitamins C enhances the absorption of iron from plant-based foods, which is important for individuals who follow a vegetarian or vegan diet.
5. Wound healing: Vitamins C is involved in the healing of wounds and tissue repair.

Vitamins C deficiency can lead to a condition known as scurvy, which can cause symptoms such as fatigue, weakness, joint pain, and bleeding gums. However, vitamins C deficiency is rare in developed countries, as it is found in many foods and is also available in supplement form.

Overall, consuming adequate amounts of vitamins C through diet and/or supplements can help support immune function, collagen synthesis, antioxidant function, iron absorption, and wound healing, among other physiological processes in the body.
