Cod Liver Oil: 8 Health Benefits Worth Holding Your Nose For
The oil looks like liquid gold gel, and the capsules look like pearls of trapped sunlight. But one whiff — forget taste — and most people’s resolve wavers. If we were to make a list of good things that look great but smell and taste awful, cod liver oil would top the list.
Cod liver oil has been a household staple for generations, and for good reason — it’s one of the few natural sources that combines vitamin A, vitamin D, and omega-3 fatty acids in a single supplement.
1. Supports Bone Health
Vitamin D is essential for calcium absorption, and cod liver oil is one of the richer natural dietary sources of it — particularly useful for people with limited sun exposure.
2. Supports Vision
Vitamin A plays a direct role in maintaining healthy vision, particularly in low-light conditions, and supports the health of the eye’s surface tissue.
3. Supports Heart Health
Omega-3 fatty acids (EPA and DHA) are associated with healthier triglyceride levels and overall cardiovascular support.
4. Supports Joint Comfort
Omega-3s have anti-inflammatory properties that many people find helpful for general joint comfort, particularly with consistent long-term use.
5. Supports Skin Health
Vitamin A supports skin cell turnover, while omega-3s help maintain the skin’s natural moisture barrier.
6. Supports Immune Function
Vitamin D plays a meaningful role in immune regulation, and adequate levels are associated with better overall immune resilience.
7. May Support Immune Balance in Autoimmune Conditions
Omega-3 fatty acids have documented anti-inflammatory effects and some research has explored their role in supporting immune balance in autoimmune conditions. Anyone managing an autoimmune condition should discuss supplement use with their doctor.
8. Supports Brain Health
DHA, a key omega-3 fatty acid, is a major structural component of the brain, and adequate intake is linked to cognitive function support across life stages.
Genetics and Nutrient Absorption
Not everyone absorbs and uses these nutrients the same way. Genetic variation affects how efficiently the body converts and utilises fat-soluble vitamins like A and D, and how effectively it processes omega-3 fatty acids — which is part of why the same daily dose can affect two people differently.
Important: Consult with your physician before starting a course of cod liver oil, especially if you are on blood thinners or other medications.
Know Your Vitamin & Nutrient Genetic Profile
Your genes influence how your body absorbs and utilises vitamins A, D, and omega-3 fatty acids — meaning your optimal supplement needs may be different from someone else’s. Genomepatri by MapmyGenome reveals your personalised nutritional genetic profile so you can supplement smarter.
