Vitamin C, also known as ascorbic acid, is an essential nutrient that plays a crucial role in maintaining our health. It is a water-soluble vitamin that our body cannot produce, and we need to consume it regularly through our diet. In this article, we will explore the natural sources of Vitamin C, its health benefits, recommended daily intake, and more.
The discovery of Vitamin C can be traced back to the 18th century when sailors discovered that consuming citrus fruits could prevent scurvy, a debilitating disease. The first isolated Vitamin C was obtained from citrus fruits in 1928. Since then, numerous studies have been conducted to understand the importance of this vital nutrient.
II. Natural Sources of Vitamin C
Fruits and vegetables are the best sources of Vitamin C. Some of the natural sources of Vitamin C include:
