Vitamins are essential organic compounds that play a crucial role in maintaining overall health and supporting various bodily functions. They are categorized into two main groups: fat-soluble vitamins (A, D, E, K) and water-soluble vitamins (B-complex and C). Fat-soluble vitamins are stored in the body's fatty tissues, while water-soluble vitamins need to be consumed regularly. Vitamins support metabolism, enhance immune function, and contribute to cell growth and repair. They act as antioxidants, protecting cells from oxidative stress. A well-balanced diet rich in fruits, vegetables, whole grains, and lean proteins is vital for obtaining adequate vitamins. Deficiencies can lead to serious health issues, making it essential to ensure proper vitamin intake, either through diet or supplementation, to promote overall well-being and prevent diseases.
