Vitamin A serves as catalyst for many biochemical processes. It serves as an antioxidant, protecting the body against pollutants and free radicals, hence against cancer. Vitamin A plays a role in the secretion of gastric juices needed for protein digestion and plays a vital role in building strong bones, rich blood and visual purple (Rhodopsin – the ability to sense red.)

Sources of Vitamin A (Retinol) include butterfat, egg yolks, liver and other organ meats, seafood and fish liver oils. Provitamin A (carotene) is found in yellow, red, orange or dark green fruits and vegetables. Carotenes are converted to Vitamin A in the upper intestine in the presence of fat. Antibiotics, laxatives, fat substitutes and cholesterol- lowering drugs interfere with Vitamin A absorption.
