Discover the science of EPA and DHA content in our essential guide to Omega-3 Power. This page unpacks what epa and dha content means and how researchers quantify it in products and ingredients. EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are two long-chain omega-3 fatty acids, and the term epa and dha content refers to the amount of these fatty acids present per unit. On most labels you’ll see the epa and dha content expressed as milligrams per serving or per capsule, and sometimes as a share of total fatty acids. Understanding these numbers helps you interpret product information consistently, regardless of the source category. To compare options, you’ll want to look at how the epa and dha content stacks up across servings. We explain differences between listing EPA and DHA separately versus as a combined line, and how serving size influences the numbers. You’ll also see sometimes a total omega-3 content alongside the epa and dha content, which can affect comparison across products. The guide shows how to read these figures so you can evaluate the epa and dha content in a clear, apples-to-apples way. Our essential guide highlights categories of sources by how they contribute to epa and dha content, rather than by flavor or culinary use. We discuss how the epa and dha content can vary by source class and processing method, and how different formats present these numbers. The focus is on understanding the content label: is EPA listed first, is DHA shown as a separate line, and is the serving size consistent? By examining these aspects, you can compare options based on epa and dha content. Behind the numbers, rigorous science yields EPA and DHA content figures. We describe the analytic approaches used to quantify EPA and DHA, including sample preparation, lipid extraction, and chromatographic analysis. The content is reported in milligrams per serving or per gram, with notes on the basis of measurement and any applicable standard reference materials. Quality controls, repeat analyses, and, where applicable, third-party verification help ensure the EPA and DHA content data you rely on is reliable. The page also covers how variations in product form and manufacturing practices can influence the epa and dha content presented on labels.
