Fat-soluble vitamins are absorbed through the intestinal tract with the help of lipids (fats). Because they are more likely to accumulate in the body, they are more likely to lead to hypervitaminosis than are water-soluble vitamins.

It outlines dietary sources and the differences in bioconversion factors among organizations, affecting vitamin A intake assessments. High intakes can lead to toxicity, particularly during pregnancy, and while some countries set upper intake levels, these do not apply to deficient populations that may benefit from supplementation.
