However, people assigned female at birth experienced more bone mineral strength. This suggests cod liver oil could be especially beneficial for this demographic.

Consuming cod liver oil may offer added bone health benefits due to its vitamins A and D content. These nutrients support bone density and overall skeletal strength.

5. Reduce Joint Pain

Cod liver oil, rich in omega-3 fatty acids, helps alleviate joint pain. The EPA and DHA in it reduce inflammation in joints. Vitamins A and D further support joint health by promoting immune function.

For those with arthritis, studies show omega-3s can lessen pain and improve mobility. Cod liver oil’s anti-inflammatory properties make it a natural choice for joint discomfort relief.

Regular intake may lead to significant improvements in joint function and pain reduction.

6. Support Eye Health

Cod liver oil offers significant benefits for eye health. Glaucoma and age-related macular degeneration (AMD) are leading causes of vision loss, affecting millions worldwide.

Cod liver oil’s omega-3 fatty acids, including EPA and DHA, can reduce eye pressure and nerve damage, which are risk factors for glaucoma.

Rich in vitamin A, cod liver oil helps maintain optimal vision. Research shows diets high in vitamin A lower the risk of glaucoma and AMD. However, moderation is key, as excessive vitamin A may cause toxicity.

Overall, incorporating cod liver oil into one’s diet can support better eye health and slow degeneration processes.

7. Improve Symptoms of Anxiety and Depression

Cod liver oil can lower inflammation and reduce anxiety and depression symptoms due to its omega-3 fatty acids. Research involving 21,835 participants found fewer anxiety and depression symptoms in those who regularly consumed cod liver oil.

Although omega-3’s overall effect is small, it still contributes to mental health improvements. Some studies show mixed results, especially in older adults.

Also, vitamin D in cod liver oil might bind to brain receptors and release mood-improving hormones like serotonin, potentially easing depression symptoms. More research is needed to strengthen these findings.

8. Help Heal Stomach and Gut Ulcers

Cod liver oil helps heal ulcers in the stomach and gut. These ulcers are small breaks in the lining of these organs, causing nausea, upper abdominal pain, and discomfort.

Bacterial infections, smoking, anti-inflammatory medications, and excess stomach acid often cause ulcers.

Researchers found that both low and high doses of cod liver oil healed ulcers in animal studies. Cod liver oil shows promise in treating ulcers, particularly in the stomach and gut. However, more studies in humans are needed to confirm these results.

9. Glaucoma Prevention and Treatment

Glaucoma is a leading cause of blindness. Cod liver oil, rich in vitamin A, helps prevent cellular damage from oxidation, a known factor in glaucoma development.
