Recommended Dosage

Standard Dose1–3 g EPA+DHA/day
Minimum250 mg EPA+DHA/day (maintenance)
Maximum5 g/day (therapeutic, under supervision)
TimingWith meals to improve absorption and reduce GI upset
Notes: Focus on combined EPA+DHA content, not total fish oil. Triglyceride-form fish oil (not ethyl ester) absorbs better. Algae-based DHA is a vegan alternative.
