What is true about the body's required vitamins?

Vitamins are essential organic compounds that are required in small amounts for various physiological functions. Most vitamins cannot be synthesized by the human body in sufficient quantities and therefore must be obtained from dietary sources. This includes vitamins such as Vitamin C and several B vitamins, which are vital for processes like energy production, immune function, and cellular repair.

While the body can synthesize some vitamins, such as Vitamin D through sunlight exposure, the majority must be consumed through food or supplements. This highlights the importance of a well-balanced diet rich in fruits, vegetables, whole grains, and proteins to meet the body's vitamin requirements. Understanding this is crucial for ensuring proper nutrition and preventing deficiencies that can lead to health issues.
