Accumulation of retinol/retinyl esters in liver and other organs causes oxidative stress, fibrosis risk.

Examples & evidence

• One case report: a person habitually ingesting ~13,000 µg vitamin A supplement daily developed cirrhosis; improvement after stopping. Guidance: “Fat-soluble vitamins such as vitamins A, D… may lead to liver or kidney damage when taken in very high amounts.”
