Fresh fish oil tastes neutral and does not smell. A strong odor of fish in omega-3 products tells us that the oil is rancid, which is not good for us. Randic fish oil pulls at our supply of vitamins C and E (our most important antioxidants) so as to neutralize the oxidized oil. Oxidization/going rancid increases the attacks on tissue by free radicals, which is the basis for many illnesses and early aging.
