The key difference between fat soluble and water soluble vitamins is that the fat soluble vitamins are soluble in fat hence, the body absorbs them when bile salts are available while the water soluble vitamins are soluble in water hence the body can easily absorb them.
Vitamins are essential food factors that require the proper utilization of the other nutrients such as proteins, carbohydrates, lipids, etc. Furthermore, they are important for our growth, cell differentiation, for other cellular functions. Thus, there are two main types of vitamins namely fat soluble vitamins and water soluble vitamins. Therefore, the solubility of the vitamin determines its action within the body.
