Today on YTC, we had Morley Robbins back on the show to discuss the latest research he has uncovered and synthesized regarding Retinol. Retinol is a component of the Vitamin A complex and is a key player in regulation iron and copper. It also plays an essential role in neutralizing the damaging effects of sunlight on the skin. Without retinol, the oxidative stress and free radicals produced by sunlight can lead to skin cancer, but sufficient levels of retinol prevent that damage. We also discuss how oral vitamin D supplementation inhibits retinol production.
