Why Are Some Vitamins Toxic?

Vitamins are essential nutrients, but their fat-soluble nature (especially Vitamins A, D, E, and K) means they can accumulate in the body, leading to toxicity. Water-soluble vitamins are generally excreted if taken in excess, but fat-soluble vitamins require careful monitoring.
