TED-Ed: How do vitamins work? - Ginnie Trinh Nguyen

Vitamins are essential organic compounds that support various bodily functions. They are categorized into water-soluble and fat-soluble types, affecting how they are absorbed, transported, and stored. Water-soluble vitamins, like vitamin C and B-complex, are easily absorbed and need regular replenishment, while fat-soluble vitamins, such as A, D, E, and K, are stored in the liver and fat tissues. Each vitamin has specific roles, from energy release to bone health and immune function. Maintaining a balanced intake is crucial, as deficiencies or excesses can lead to health issues.
