Vitamin A is a fat-soluble vitamin that is found in food. Vitamin A in the form of retinol and retinyl esters can only be found in animal foods like liver, milk and milk products and eggs. Vitamin A in the form of provitamin A, a precursor of vitamin A, is increasingly found in plant products like sweet potatoes, carrot juice, pumpkins or raw corn. Regardless of whether you choose vitamin A in the form of retinol, retinyl ester or a provitamin A, all versions that we carry are extremely high-quality.
