Written by Andrew Le, MD

UpdatedNovember 13, 2024

Inflammation is a common issue that can lead to various health problems, including joint pain and weakened immune function. Chronic inflammation can significantly impact one's quality of life and overall well-being if left unchecked.

Numerous over-the-counter and prescription medications are available to manage inflammation. However, many of these medications, such as Nonsteroidal anti-inflammatory drugs (NSAIDs), can cause side effects, such as stomach ulcers, and an increased risk of cardiovascular problems (e.g., heart attack and stroke),

Fortunately, cod liver oil supplements offer a natural, safer alternative for combating inflammation. Derived from the livers of cod fish, these supplements are rich in omega-3 fatty acids, vitamins A and D, known for their potent anti-inflammatory properties.

Incorporating high-quality cod liver oil supplements into your daily routine can reduce inflammation. Continue reading to know the top 7 best cod liver supplements to help you achieve these benefits and improve your overall well-being!

Understanding Cod Liver Supplements

Cod liver oil, derived from the livers of Atlantic cod, is a valuable dietary supplement known for its numerous health benefits, particularly in reducing inflammation.

Primarily rich in omega-3 fatty acids, specifically EPA and DHA, cod liver oil also boasts significant levels of vitamins A and D, essential for overall health. The concentration of these nutrients can vary depending on the cod species, scientifically termed Gadus, from which the oil is obtained.

Unlike other fish oils from deep-sea cold-water fish species like tuna, trout, mackerel, herring, salmon, and cod, cod liver oil is exclusively extracted from cod livers. This distinction is vital; while it contains fewer omega-3 fatty acids than regular fish oils, it offers higher concentrations of vitamins A and D.

Effectiveness of Cod Liver Supplements for Inflammation

The anti-inflammatory properties of cod liver oil primarily stem from its omega-3 fatty acids, which can effectively reduce pain and swelling, particularly beneficial in conditions such as arthritis.

A notable study demonstrates that cod liver oil supplements can significantly decrease the need for NSAIDs in patients with rheumatoid arthritis (RA). Approximately 40% of patients taking cod liver oil were able to reduce their daily NSAID intake by more than 30%, a substantial decrease compared to just 10% in the placebo group.

This suggests that cod liver oil could be a valuable additional treatment option to help manage RA symptoms naturally. Importantly, the study also indicated that while the supplement reduced NSAID usage, it did not significantly alter disease activity or cause additional side effects, highlighting its potential as a safe adjunct therapy for RA.

Safety

Cod liver oil is generally safe for most adults when consumed in recommended amounts, typically within daily vitamin A and D intake limits.

However, excessive doses may lead to vitamin toxicity, potentially resulting in side effects such as heartburn, nausea, and an increased risk of bleeding.

Individuals taking medications for diabetes or high blood pressure, or using blood thinners should exercise caution, as cod liver oil may interact with these drugs and affect their efficacy.

Usage

Cod liver oil is commonly available in liquid form or capsules and is typically consumed in doses of 15-20 mL daily for specific durations, depending on the health condition being addressed. Consulting with a healthcare provider is essential to determine the appropriate dosage and avoid potential interactions with other medications or supplements.
