What are the factors that affect vitamin A absorption?

Factors Affecting Vitamin A Absorption

Several factors can impair the absorption of vitamin A, even when consuming adequate dietary sources. These include:

• Liver conditions: The liver plays a crucial role in storing and metabolizing vitamin A. Liver disorders can hinder vitamin A absorption and utilization.

• Small intestinal bacterial overgrowth (SIBO): SIBO can interfere with the absorption of fat-soluble vitamins, including vitamin A, by disrupting the gut microbiome and causing inflammation.
