While vitamin A is best known for its vital role in vision, the retinoid forms of this vitamin also participate in physiological activities related to the immune system, inflammatory system, maintenance of epithelial and mucosal tissues,(colon related) growth, reproduction, bone development, creation of red blood cells, and production of spermatozoa (male reproductive cells). In food, retinoid forms of vitamin A typically appear as retinyl esters. The body is typically able to convert these retinyl esters into metabolically active forms of vitamin A including retinol, retinal, and retinoic acid.
