This episode features our first guest, Grant Genereaux, whose pioneering work shows  retinol from animal foods, carotenoids from plant foods, and 'Provitamin A' skin treatments may actually be a lot more dangerous than we might imagine, and that there is abundant scientific research showing that excessive vitamin a in all forms is extremely toxic.In the second half of the interview we go further down the rabbit hole and explore how vitamin a was first discovered and classed as the first vitamin, and explore the validity of that classification.Please note that when we feature guests, as in this episode, our goal is to have them share what they have to teach us, because it may be helpful and accurate, but that we do not necessarily endorse their perspectives. We may sometimes have different guests with opposite ideas, and rather than bringing people on just to argue with them, our goal is to encourage them to share their perspective and ask clarifying questions, but it's ultimately up to you to decide what is true and what is relevant for you.References from this episode:RP - Detoxification Grant Genereux  Books Grant Genereux Discussion ForumThere are many other studies referenced on the forum HERERE: Birth DefectsTeratogenicity of High Vitamin A IntakeList of authors.Kenneth J.
