Which type of vitamins are less likely to reach deficiency levels due to their absorption mechanism?

Fat-soluble vitamins, which include vitamins A, D, E, and K, are absorbed through dietary fats in the body. This absorption mechanism allows them to be stored in the liver and fatty tissues, making it less likely for the body to reach deficiency levels compared to water-soluble vitamins. Since they can accumulate, these vitamins are retained for longer periods, providing a reservoir that the body can draw upon when needed.

In contrast, water-soluble vitamins are not stored in the body and are excreted more readily through urine, which means that deficiencies can occur more quickly if these vitamins are not consumed regularly. Mineral vitamins, while also important, are not classified in the same categories as vitamins, so they do not fit the context of the question. Supplemental vitamins can vary widely in absorption and storage characteristics, depending on their specific formulation and the individual's nutritional status. Therefore, the nature of fat-soluble vitamins and their storage in the body clearly illustrates why they are less likely to lead to deficiency.
