Cod Liver Oil — Nutrients, Health Benefits, and Shopping Tips

Opt for cod liver oil that is cold-pressed and comes in dark bottles to protect it from light degradation. It should have a pure, mild fish flavor without any rancid aftertaste. Look for products that are certified free from heavy metals and other contaminants.

Do not use cod liver oil that smells strongly of fish or has a bitter taste, as these characteristics can indicate oxidation. Quality cod liver oil should be smooth and not cause lingering unpleasant flavors.

Cod liver oil should be stored in a cool, dark place to maintain its potency. Keep it in an airtight bottle to prevent oxidation. Properly stored, cod liver oil can last up to a year.

Exposure to heat and light can cause cod liver oil to become rancid. Avoid storing it near the stove or in direct sunlight. Ensure the bottle is tightly closed to preserve its nutritional value and prevent spoilage.

Cod liver oil can last for 1-2 years unopened when stored in a cool, dark place. Once opened, it should be refrigerated and used within 3-4 months. Always check the expiration date on the packaging for the best quality.

Leftover cod liver oil is highly beneficial and can be used in various health-related applications. In cooking, it’s primarily consumed as a dietary supplement rather than used directly in recipes due to its strong taste. It is rich in omega-3 fatty acids and vitamins A and D, which are beneficial for heart health, bone strength, and immune function.

Beyond cooking, cod liver oil has several non-culinary uses. It can be applied topically to help moisturize dry skin or soothe minor wounds and skin irritations. Cod liver oil can also be used as a supplement for pets, improving their coat health and joint function. Additionally, it has been used in traditional remedies to help alleviate joint pain and inflammation due to its anti-inflammatory properties. Cod liver oil can also be used to condition wooden cutting boards and utensils, helping to maintain their longevity and appearance.

Cod liver oil is an excellent source of omega-3 fatty acids, promoting heart health by lowering cholesterol and reducing inflammation. It is rich in vitamins A and D, which support immune health and bone health by promoting calcium absorption. Cod liver oil is also beneficial for brain function, improving memory and cognitive health. Its high nutrient content makes it a valuable supplement for overall well-being, but it should be consumed in moderation to avoid excess vitamin intake.
