vitamins and minerals that are water soluble or fat soluble. whats the difference
Water soluble (Vitamin C and all of the B vitamins): Water soluble vitamins are vitamins that our bodies do not store. These vitamins dissolve in water when they are ingested, then go in to the blood stream. The body keeps what it needs at that time, and excess amounts are excreted in the urine. Since they can’t be stored, everybody needs a continuous supply of water soluble vitamins in order to stay healthy.
Fat Soluble (Vitamins A, D, E and K): Fat soluble vitamins are those that are normally stored in the body. When these vitamins are ingested, they dissolve in fat. In a person with a healthy digestive system, the body uses what it needs at that time and stores the rest for future use.
