Understanding the Difference Between Vitamins and Minerals
Vitamins and minerals are both micronutrients necessary for the proper functioning of the human body. However, they differ in their chemical nature and how they are obtained and utilized by the body.
What are Vitamins?
- Vitamins are organic compounds, meaning they contain carbon.
- They are essential for various bodily functions, including growth, development, and metabolism.
- Vitamins are typically obtained through diet, as the body cannot synthesize most of them in sufficient amounts.
- Examples include Vitamin C, Vitamin D, and the B vitamins.
What are Minerals?
- Minerals are inorganic elements, meaning they do not contain carbon.
- They are essential for various physiological processes, such as building strong bones and teeth, nerve function, and fluid balance.
- Minerals are obtained from the earth and are absorbed by plants and animals, which are then consumed by humans.
- Examples include calcium, iron, and zinc.
