Omega-3 supplements are very beneficial to your health but some people may find a little complicated to understand all the abbreviations used on the products’ ingredients list. EPA, DHA and ALA. What do they stand for? Which food sources can you get them from? How much do you actually need? Let’s have a quick look at DHA, EPA and ALA.
One of the two main types of long-chain omega-3 fatty acids, Eicosapentaenoic Acid, or EPA, is found in fatty, cold-water fish such as mackerel, sardines, salmon, herring, halibut, trout, anchovies, and tuna. There is no recommended standard dose of EPA’s but health organizations recommend a daily dose of 250 to 500 milligrams (mg) for healthy adults.
The other main type of omega-3 is Docosahexaenoic Acid, popular known as DHA. Plentiful in fish and shellfish, DHA is also found in algae. There is no set recommended standard dose of DHA as well but just like EPA’s a daily dose of 250 to 500 milligrams (mg) of DHA should be sufficient for healthy adults.
EPA to DHA Ratios
It’s important to check for the ratios of EPA and DHA since there is no standard daily dose set. According to the American Heart Association, a common ratio which can be used is 180 milligrams of EPA to 120 milligrams of DHA but some reports show that ratios of 2:1 or 1:2 EPA to DHA may be equally beneficial since both compounds seem to work together.
Alpha-linolenic Acids are short-chain omega-3 fatty acids found in plants, such as flax seeds, chia seeds, as well as oils such as flax oil and hemp oil. ALA omega-3 fatty acids have less potent health benefits than EPA and DHA and for the body to truly benefit from these fats, they must be converted into long-chain EFAs such as EPA and DHA first. There is no established dose of alpha-lipoic acid recommended, but studies have concluded that the use of 600 milligrams daily can provide health benefits.
