Omega-3: Why must the DHA value be higher than the EPA value?

different companies make different ratios of DHA and EPA. This is what you need to know. DHA is more targeted to brain health and EPA targets cardio health. Buy the one with the ratio that more fits what you want to accomplish. EPA 1200-1600 mg. and/or DHA 800-1200 mg daily is a good amount and is quite safe. Again remember what is your goal. Absorption is not an issue because all clinical trials as to fish oil benefits are done with calculating the amount ingested not so much the amount absorbed.
