In a case study from the HPA-D unit, you mentioned a patient with high cortisol” or high free cortisol, I’m assuming he means. “… high cortisol metabolites and high cortisone. Additionally you mentioned the patient had eye floaters. Have you noticed any underlying dysfunctions specifically related to eye floaters?

Chris Kresser: Nothing comes to mind off the top of my head. I mean, hypertension could potentially cause that and metabolic dysfunction. Vitamin A deficiency, I think, can contribute to floaters, and that is common, as you know, because vitamin A is really only present in pasture-raised dairy, organ meats, and cod liver oil, and a lot of people can’t convert beta-carotene into retinol. So those are the things that I tend to think of first.
