What affects vitamin A absorption?

The efficiency of vitamin A and carotenoid intestinal absorption is determined by the regulation of a number of proteins involved in the process. Polymorphisms in genes for these proteins lead to individual variability in the metabolism and transport of vitamin A and carotenoids.

What nutrients need to be digested before absorbed?

Most of the nutrients in the food you eat such as protein, fats, carbohydrates and fat-soluble vitamins need to undergo some amount of digestion before they can be absorbed.
