In this episode we discuss:

• The research behind vitamin A toxicity and whether vitamin A is really a poison
• Whether you need to be concerned about the use of Accutane
• Whether retinoic acid is toxic because it’s used as a chemotherapeutic agent
• Whether Grant Genereux’s claims about vitamin A toxicity are valid
