Eczema is an itchy, inflammatory disease that affects the skin, though outbreaks may be limited to certain areas. While fish oil is not an FDA approved method of treating eczema or other skin disorders, it has been noted for its benefits.
Learn about the different forms. Fish oil comes in a variety of forms such as pills, liquid and even chewables for children. There are many brands and not all of them are created the same or offer the same dosage. You can also use flax seed, as it contains the same ingredients and is a little milder. Flax seed oil and fish oil are sold in liquid in dark bottles. Keep the bottles out of direct sunlight, preferably refrigerated. If you purchase the capsules, these should be kept in a cool, dry place out of reach of children. Do not give small children capsules to swallow. Purchase the chewable gummies or mix a little fish oil in their juice.
Consider using Omega 3 oil in conjunction with other treatments. Rubbing it on the skin only or using creams that claim to include it may not be very effective. You need to ingest the Omega 3 oil daily. You are best taking it with food or milk a few times a day. If you take too much at once, it may be hard on your digestive system.
Keep a food journal of everything you eat and how much fish oil (or flax seed) you are taking, as well as dosage. Also note in the journal if you see any improvements in your skin. Note how much time it took to see results.
If you don't like the fishy aftertaste of fish oil there are alternates like flax and higher quality fish oil. Fish Oil is beneficial as it offers Omega-3, something that is found in diets, but not in the amounts it is needed. It is also an antioxidant. There are low cost nutritional outlets listed in Resources. Shipping is generally minimal and you have your product in a week or less.
Ask a dermatologist or other doctor before starting any new regimen. Start with the lowest, effective dose.
