Vitamin C, also known as ascorbic acid, plays an important role in animal health, acting as a powerful antioxidant that protects cells from damage caused by free radicals. It is essential for the synthesis of collagen, a protein essential for maintaining healthy skin, tendons, ligaments and blood vessels, which is crucial for maintaining the structural integrity of tissues and rapid recovery from injury. Vitamin C is also important for the proper functioning of the immune system, as it supports the function of leukocytes (white blood cells), which are key in fighting infections. It helps to regenerate other antioxidants, such as vitamin E, which further increases the body's defense capabilities. In addition, vitamin C plays a role in energy metabolism, participating in the biochemical transformations that convert fats, proteins and carbohydrates into energy. In cases of stress, illness or physical exertion, additional doses of vitamin C can support faster recovery and a stronger immune system.
