Cod liver oil has been around for centuries, yet most people don’t realize how truly powerful this golden liquid can be. While your doctor might recommend a general omega-3 supplement, cod liver oil offers something uniquely potent—thanks to its natural blend of vitamins A and D, plus EPA and DHA fatty acids. If you’re looking for ways to protect your joints, brain, heart, or even your vision, cod liver oil might just deserve a spot in your daily routine.
In this article, we’ll reveal 10 lesser-known but research-supported benefits of cod liver oil. You’ll discover how it supports a strong immune system, reduces inflammation, and may even improve mood. Let’s explore what this traditional remedy can do for your modern health.
1. Helps Reduce Inflammation Naturally
Cod liver oil is rich in EPA and DHA—omega-3 fatty acids that play a critical role in managing inflammation. Chronic inflammation is linked to numerous conditions, including arthritis, heart disease, and cognitive decline.
Studies from the Journal of Rheumatology suggest that omega-3 supplements like cod liver oil can significantly reduce joint pain and stiffness in people with rheumatoid arthritis. It’s not a cure, but it may help you move more freely and comfortably.
2. Supports Joint Health and Flexibility
Joint discomfort isn’t just about inflammation—wear and tear over the years also play a part. Cod liver oil may support cartilage health and joint lubrication, allowing for better mobility.
One study published in Rheumatology International found that regular supplementation of cod liver oil reduced the need for NSAIDs in arthritis patients. That’s a big win for anyone seeking more natural relief.
3. Promotes a Healthy Heart
Cod liver oil supports heart health in several ways. The omega-3s in it help reduce triglyceride levels, support normal blood pressure, and lower the risk of arterial plaque buildup.
According to the American Heart Association, omega-3s can reduce the risk of heart disease, especially when combined with a balanced diet and lifestyle.
4. Enhances Brain Function and Mood
Fatty acids are essential for brain health—and DHA, found in cod liver oil, is one of the most important. It’s particularly helpful for older adults concerned about memory or cognitive decline.
Research in the Journal of Clinical Psychiatry suggests that omega-3s may have a positive effect on mood and help support emotional balance. Some early studies also hint that vitamin D (also found in cod liver oil) may help reduce symptoms of seasonal mood changes.
5. Strengthens Immune Function
Vitamin A and D in cod liver oil are immune system superheroes. Vitamin A helps maintain the integrity of the skin and mucous membranes—your body’s first line of defense—while vitamin D supports immune cell function.
A study in the British Medical Journal found that people with higher vitamin D levels had a lower risk of respiratory infections, especially during winter months.
6. Supports Eye Health and Vision
Vitamin A is vital for maintaining good vision, especially night vision. Cod liver oil contains a natural, bioavailable form of this vitamin, which helps protect the cornea and retina.
Some evidence from the American Academy of Ophthalmology suggests that a diet rich in vitamin A may help slow the progression of age-related macular degeneration (AMD), one of the leading causes of vision loss in seniors.
7. Promotes Bone Strength
Vitamin D is essential for calcium absorption, and cod liver oil offers a significant natural source. Strong bones start with adequate vitamin D—especially important for postmenopausal women and older adults.
Cod liver oil may reduce the risk of bone thinning and fractures, especially when paired with a calcium-rich diet and regular exercise.
8. Supports Skin Health
Cod liver oil may help hydrate and nourish your skin from the inside out. Vitamin A helps with cell turnover and skin repair, while omega-3s reduce inflammation and redness.
Some anecdotal reports and small studies suggest cod liver oil may even help with conditions like eczema or dry skin—although more research is needed.
9. Aids in Nutrient Absorption
Fats help your body absorb fat-soluble vitamins like A, D, E, and K. Because cod liver oil is a natural source of both healthy fats and fat-soluble vitamins, it enhances your body’s ability to use these nutrients effectively.
This makes it especially valuable for older adults or those with digestive issues that impair nutrient absorption.
10. May Help Balance Hormones
Cod liver oil’s combination of omega-3s and vitamin A may support hormone regulation, particularly in women during menopause or hormonal shifts. Though research in this area is still emerging, some integrative medicine practitioners recommend it as part of a natural hormone balance approach.
How to Take Cod Liver Oil Safely
If you’re considering adding cod liver oil to your routine, here are a few tips:
- Choose a high-quality, purified brand to avoid contaminants.
- Follow dosage instructions—more isn’t always better.
- Consult your doctor if you take medications or have health conditions.
Cod liver oil can be taken in liquid or capsule form. The taste may not be for everyone, but flavored versions or capsules make it easier to include daily.
Final Thoughts
