Water soluble vitamins are all of the B vitamins and vitamin C. Water-soluble vitamins dissolve easily in water and, in general, are readily excreted from the body after the nutritious components are absorbed.

Fat soluble vitamins are vitamins A, D, E, and K. Fat-soluble vitamins are absorbed through the intestinal tract with the help of lipids (fats) and are stored in the liver until they are needed.

The vitamins are ingested and are broken down by acids in the stomach. After being broken down, the base vitamins are absorbed and transferred around the body by cells. Water-soluble vitamins are sent straight to the places where the vitamins are used and then the remains are excreted. (Ex. Vitamin B12 goes the brain to strengthen it).

The fat-soluble absorption process is slightly more complicated. After the vitamin is broken down, it goes with lipids into liver cells to be stored into the vacuoles. When the body needs the vitamin, it goes its designated area in the body where it makes repairs or improvements.
