Fish Liver Oil and Acne

Fish liver oil has long been the bane of children whose mothers swore by its health-boosting benefits. As it turns out, it does have healing properties, including being a possible treatment for acne. Fish liver oil primarily comes from cod and is available in liquid or capsule form. But before you rush out to stock up on this supplement, be aware that it can cause serious side effects. Do not take it without your doctor's advice, especially if you have a medical condition.

How Fish Liver Oil May Help Acne

Fish liver oil is a rich source of vitamins A and D, both of which are essential for healthy skin. Vitamin A is available in pharmaceutical preparations --- such as isotretinoin --- for treating acne. Fish oils also contain the omega-3 fatty acids eicosopentanoic acid, or EPA, and docosahexaenoic acid, or DHA. These fatty acids have potent anti-inflammatory properties, which makes them useful in fighting the inflammation that plays a role in acne.

Research

In a study published in "Lipids in Health and Disease" in 2008, a team of Canadian and American researchers found that taking omega-3 fish oil-based supplements for two months helped to reduce acne lesions from 62.8 to 40.4 on average after two months. The supplement also helped to improve patients' mental, emotional and social well-being. However, the researchers point out that because the study was small, the results are only suggestive of how omega-3 may benefit acne sufferers and more research is needed.

Side Effects

Some fish liver oil products contain high levels of vitamin A. In large doses, or taken for a long period of time, vitamin A is toxic. Look for brands with packages that clearly indicate they contain low levels of vitamin A. Also, fish oil can cause stomach upset and nausea and may leave a fishy smell on your breath when you burp. Do not take fish liver oil without a doctor's advice, especially if you're taking medications such as blood thinners. Avoid taking cod liver oil if you are pregnant, asthmatic or allergic to cod and develop symptoms such as hives or difficulty breathing.

Considerations

Fish liver oil alone won't banish your blemishes. To prevent risk of vitamin A toxicity if you take fish oil, use the type made from the whole fish, not just the liver. Consult a dermatologist for more advice on treating acne. She may recommend using over-the-counter medications such as benzoyl peroxide or salicylic acid or prescription medications such as retinoids like tretinoin. Also, eat a well-rounded diet that includes vegetables, fruits, whole grains and fish.
