Which essential vitamin can be found in high concentrations in citrus fruits?

Citrus fruits are renowned for their high concentrations of vitamin C, which is a vital nutrient for the body. Vitamin C, also known as ascorbic acid, plays a crucial role in various physiological processes. It is essential for the growth and repair of tissues, acts as an antioxidant to help protect cells from damage, and is important for the immune system.

Citrus fruits like oranges, lemons, limes, and grapefruits are particularly high in this vitamin, making them a popular choice for boosting vitamin C intake. Drinking orange juice or eating a grapefruit can significantly contribute to daily vitamin C requirements. The important functions of vitamin C underscore why it is emphasized in nutrition, especially in relation to dietary sources like citrus fruits.
