Final answer:
Water-soluble vitamins are not stored in the body and excess amounts are excreted in urine, making the body more tolerant of them as compared to fat-soluble vitamins.
Step-by-step explanation:
Water-soluble vitamins, including the eight B vitamins and vitamin C, are absorbed with water in the gastrointestinal tract. These vitamins move easily through bodily fluids, which are water based, so they are not stored in the body. Excess water-soluble vitamins are excreted in the urine. Therefore, hypervitaminosis of water-soluble vitamins rarely occurs, except with an excess of vitamin supplements.
