Biotin, or Vitamin B7, is a water-soluble vitamin, which means that it dissolves in water and is not stored in the body. It is part of the B-complex group of vitamins, all of which are water-soluble. In contrast, Vitamins A, D, and K are fat-soluble vitamins, meaning they can be stored in the body's fatty tissues for later use. Therefore, they do not need to be consumed as regularly as water-soluble vitamins.
