What it is
Most cheap fish oils use the ethyl ester (EE) form, but rTG absorbs about 70% better. A 2024 review confirmed rTG fish oil produces significantly higher blood EPA and DHA levels than the same EE dose. No rTG-specific outcome RCTs exist, but superior bioavailability supports better dose efficiency for cardiovascular goals.
