【vitamins】Vitamins are essential organic compounds that the human body needs in small amounts to function properly. They play crucial roles in various bodily processes, including growth, development, metabolism, and immune function. While the body can produce some vitamins in limited quantities, most must come from dietary sources. Vitamins are typically categorized into two groups: fat-soluble and water-soluble.
Below is a summary of the key vitamins, their functions, and food sources:
| Vitamin | Type | Function | Food Sources |

In conclusion, vitamins are vital for maintaining overall health and well-being. A balanced diet that includes a variety of foods can help ensure adequate intake of all necessary vitamins.
