Raw wild-caught cod Liver Oil is one of the best "supplements" as it is packed with the right omega 3 fatty acids (DHA + EPA), Vitamin A for skin health, Vitamin D for mental health and hormone synthesis, vitamin K2, Vitamin E, antioxidants, and Iodine + selenium which are lacking in the modern diet.I couldn't recommend implementing cod liver oil enough. it is pricy, but you want wild caught and unpasturized cod liver oil for the best nutrition.

Why Raw Wild-Caught Cod Liver Oil Is Superior
✅ Higher Nutrient Density – More intact vitamins and bioavailable omega-3s.✅ Less Processing = No Synthetic Additives – Many commercial cod liver oils remove natural vitamins and add synthetic ones.✅ Better Omega-3 Retention – Cold processing keeps fragile fatty acids intact.
How It Fits Into Your Diet
Dose: 1-2 tablespoons daily
Pair with vitamin K2 (grass-fed butter, beef liver, natto) to balance vitamin A & D absorption.
Avoid excessive heat exposure, as it can oxidize the delicate fatty acids.
