Water-soluble vitamins are a group of vitamins that dissolve in water and are easily absorbed by the body. This group includes vitamins such as Vitamin C and the B vitamins, which play essential roles in energy production, immune function, and overall health. Because they dissolve in water, these vitamins are not stored in the body and must be consumed regularly through diet. Since water-soluble vitamins are excreted in urine, it is important to maintain a balanced diet to ensure adequate intake. Foods rich in these vitamins include fruits, vegetables, whole grains, and legumes. A deficiency in water-soluble vitamins can lead to various health issues, highlighting their importance in daily nutrition.
