Which of the following statements about vitamins is true?

The statement that water-soluble vitamins are not stored in significant amounts in the body is accurate. Water-soluble vitamins, which include the B-complex vitamins and vitamin C, are typically not stored in the body and instead need to be consumed regularly through diet because any excess is usually excreted in urine. This is in contrast to fat-soluble vitamins, such as vitamins A, D, E, and K, which can be stored in the body's fatty tissues and liver for later use.

Understanding the storage capabilities of different types of vitamins is important for dietary planning and ensuring adequate intake. Since water-soluble vitamins do not remain in the body for long periods, individuals must ensure a consistent intake through a varied diet to meet their nutritional needs. This distinguishes them from other vitamins, which have different storage and excretion characteristics.
