Which statement about water-soluble vitamins is true?

Water-soluble vitamins, which include the B vitamins and vitamin C, are characterized by their ability to dissolve in water. One key aspect of these vitamins is that they are not stored in the body to any significant extent. Instead, any excess amounts are generally excreted through the kidneys into the urine. This means that regular intake from the diet is necessary to avoid deficiencies, as the body does not retain them efficiently like it does with fat-soluble vitamins.

The other statements do not accurately reflect the characteristics of water-soluble vitamins. They are not stored in bodily fat, they do not typically accumulate to toxic levels due to their excretion, and they do not provide significant caloric energy. Understanding these properties is essential in nutrition and can help individuals maintain an adequate and balanced intake of vitamins.
