Does high heat degrade Omega 3- Cod Liver Fish Oil is this why it does not contain Vitamin A & D?Updated a month ago

No, the Omega-3 fatty acids (EPA and DHA) are not damaged by heat during processing. Cod liver oil is purified under tightly controlled conditions, and stability testing shows no loss of EPA or DHA—even after long-term storage. In fact, 36-month stability studies confirm the oil maintains its Omega-3 content without degradation. This particular cod liver oil is kept in its purest form, without adding synthetic Vitamins A or D, which are often reintroduced in other products after refining. Many people prefer this natural, unfortified option to avoid synthetic additives and control their own intake of Vitamins A and D through diet or separate supplements.
