Vitamins are organic compounds that the body needs in small amounts to function properly. Each type plays a unique role in supporting different systems and processes. For example, Vitamin A, Vitamin B6, Vitamin E, and Vitamin K are all essential to maintaining good health, but they contribute in very different ways. Some support vision and skin health, others assist with immune system function, while certain ones play a role in neurological balance or circulatory processes. These vitamins are commonly found in a variety of foods—from leafy greens and whole grains to nuts, dairy, and meats. Because the body doesn’t always produce enough of these nutrients on its own, regular intake through diet or supplementation may be necessary. Understanding what each vitamin does helps people make better dietary choices and identify when adjustments might be needed to support long-term wellness.
