Is cod liver oil (CLO) the same as fish oil? Do the polyunsaturated fatty acids in it suppress your thyroid? What is the role of retinol in the body? Does vitamin A protect against lipid peroxidation in cell membranes? What are the role of fat soluble vitamins in the body?  In this solo show I answer all of these questions and more. I talk about why it took two years for Morley Robbins beating the retinol drum on my podcast to convince me to try it. In a world of “you’re anemic, copper toxic and vitamin A toxic”, it takes a lot of unlearning to get to the truth. The truth is retinol is a critical nutrient that you can be deficient in even if you’re eating grassfed beef liver everyday. Retinol is an electron carrier and a master antioxidant. Cod liver oil contains A and D in the perfect ratio in addition to compounds that probably haven’t been discovered yet. While retinol seems to be the star of CLO, I suspect that it is a synergy of nutrients that gives the full effect. I share my experience of starting to take it this year in the middle of winter and how it affected my tolerance to cold temperatures. It is a powerful whole food supplement as long as it is not fortified or fermented.
