Cod liver oil, a supplement utilized by Scandinavian Vikings as early as the 700s, offers numerous health benefits thanks to its rich content of Omega-3 fatty acids, vitamin A, and vitamin D. Originally sourced from the liver of Atlantic cod, this nutrient-packed oil has been used for centuries to treat conditions like rickets and muscle injuries. Today, it’s easily accessible in capsule or liquid form at pharmacies and supermarkets, making it convenient for modern use.
While cod liver oil is well-known for its internal health benefits, it also offers several advantages for skin care. Here are some key benefits:
1. Protects Skin from Sunburn
Omega-3 fatty acids found in cod liver oil provide protection against harmful UVA and UVB rays from the sun. These fatty acids have anti-inflammatory properties, which help safeguard skin cells from inflammation caused by sunlight and manage the body’s response to UV exposure, thereby minimizing damage. Research has shown that combining DHA and EPA, components of Omega-3, can significantly reduce skin sensitivity to UV rays.
2. Relieves Skin Conditions
Cod liver oil can also alleviate symptoms of skin conditions like atopic dermatitis or psoriasis by moisturizing the skin and combating redness, dryness, or itchiness. Omega-3 improves the function of the skin’s outer layer by retaining moisture and preventing irritation. In a study, women who consumed flaxseed oil, another Omega-3-rich oil, experienced increased skin hydration and reduced sensitivity, highlighting the potential of cod liver oil in managing similar conditions.
3. Reduces Acne
Acne, a common skin issue, can be mitigated by a diet rich in cod liver oil. The Omega-3 in cod liver oil helps reduce inflammation, a key factor in acne development. Studies have shown a reduction in acne lesions when Omega-3 supplements are taken, either alone or with other nutrients. Omega-3 can also lessen the side effects of isotretinoin, a medication often used for severe acne.
4. Fights Wrinkles
The skin’s ability to retain water, crucial for a smooth and wrinkle-free appearance, is influenced by its fatty acid composition. Consuming cod liver oil can enhance the skin’s barrier function, preventing it from becoming wrinkled, rough, or cracked. Additionally, Omega-3 helps combat inflammation caused by pollution, stress, and poor diet, which can lead to collagen breakdown and wrinkle formation.
How to Use Cod Liver Oil
Although there is no specific recommended dosage for cod liver oil, it is advised to consume it within safe limits for Omega-3, vitamin A, and vitamin D. Available in capsule or liquid form, the oil should be taken as directed on the product packaging.
However, since cod liver oil can thin the blood, those on blood thinners or pregnant women should consult a doctor before use. While Omega-3 is important during pregnancy, excessive vitamin A intake can pose risks, making professional advice essential.
