So I was just informed today by my brother, who is also on Accutane, that his dermatologist told him that he should not be taking protein powder during his course. This is the first time I have ever heard of this and I am a bit concerned... Is this really accurate? Am I really going to do much damage to my liver by taking a nutritional supplement while on this drug? I currently take Gold Standard 100% Egg, which doesn't contain any Vitamin A [Removed]. I already had to give up alcohol and sun, I would like to at least keep my body in shape.
