Yes — EPA + DHA combined is the number that matters, and it's the one most labels bury on the back. A standard "1000mg fish oil" softgel is usually about 18% EPA and 12% DHA, so roughly 300mg of actual omega-3. If the serving size is two softgels, the bottle shouting 1000mg is giving you 600mg, not 2000mg. That gap is the whole game. Once you're comparing products that clear that bar, two things separate them: Ratio. EPA and DHA aren't interchangeable. EPA is the one that dominates the triglyceride and mood research; DHA is structural — brain and retina. Most general formulas run EPA-heavy, which is fine for most people, but if you're buying for a specific reason it's worth knowing which one you're actually paying for. Freshness. Fish oil oxidizes. Rancid oil is worse than no oil, and it's common. Look for third-party testing and a manufacture date, and if you're getting fishy burps, that's not normal — that's the oil telling you it's gone off. The fastest way to compare two bottles: divide the price by the total grams of EPA + DHA in the whole bottle. That one number sorts the shelf faster than anything on the front label. The omega-3 entry in my supplement guide goes deeper on the ratio question if you want it.
