The statement that is TRUE about water-soluble vitamins is that “they must be consumed daily.” Water-soluble vitamins are a group of vitamins that dissolve in water and are not stored in the body to a significant extent. This means that they must be replenished regularly through the diet or supplements.
Water-soluble vitamins include vitamin C and all the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, biotin, folate, and cobalamin). Unlike fat-soluble vitamins (vitamins A, D, E, and K), which can be stored in fatty tissues and the liver, water-soluble vitamins are not stored to a large extent in the body.
Since water-soluble vitamins dissolve in water, any excess amounts that are consumed are usually excreted through urine. This is one reason why they need to be consumed daily, as the body does not have a significant reservoir of these vitamins.
It is important to note that absorption of water-soluble vitamins occurs mainly in the small intestine and they are typically transported directly into the bloodstream, rather than being absorbed into the lymph.
