Does the body store and use all vitamins in the same fashion?

No, the body does not store and use all vitamins in the same fashion. Vitamins are categorized into two groups: water-soluble and fat-soluble. Water-soluble vitamins (like B vitamins and vitamin C) are not stored in significant amounts and are excreted through urine, requiring regular dietary intake. In contrast, fat-soluble vitamins (A, D, E, and K) can be stored in the body's fatty tissues and liver, allowing for a more prolonged use without needing daily consumption.
