About fish oil
What it is
Fish oil is the most common omega-3 supplement. Unconcentrated fish oil is roughly 30% EPA + DHA; concentrated oils are processed to increase that share.
Forms you may see
Concentrated fish oils are usually ethyl esters or re-esterified triglycerides (rTG). Research differences between these forms mostly concern absorption with and without meals; many labels don’t state the form at all.
What to compare
Total EPA + DHA per serving, number of softgels per serving, and cost per 1,000 mg EPA + DHA.
