Dialysis is a process used to remove waste products and excess fluid from the blood when the kidneys are not functioning adequately. Water-soluble vitamins, such as Vitamin C and the B vitamins, are small molecules that dissolve in water. During dialysis, especially hemodialysis, the dialysis solution (dialysate) is capable of removing these vitamins from the bloodstream.

While some vitamins may be retained during the dialysis process, the general principle is that water-soluble vitamins are largely eliminated due to their solubility and the nature of how dialysis works. This removal is particularly significant in patients receiving regular hemodialysis sessions, which is why it is commonly recommended that patients undergoing such treatments supplement their intake of water-soluble vitamins to prevent deficiencies.

Hence, stating that dialysis does not remove water-soluble vitamins is false, as it indeed removes them during treatment. Therefore, the correct response is that the statement is false.
