Frequently Asked Questions

Why is fish oil quality important?
Most cheap fish oil is rancid (oxidized). Oxidation creates pro-inflammatory compounds — the OPPOSITE of why you take it. IFOS (International Fish Oil Standards) tests TOTOX (total oxidation). Carlson, Nordic Naturals, Thorne, Now Foods Triple Strength typically pass. Costco/random Amazon: often fail.
rTG vs EE vs TG forms?
Triglyceride (TG, natural) — best absorbed. Re-esterified TG (rTG, premium concentrates) — same absorption as natural TG. Ethyl Ester (EE, cheap concentrates) — 30% less absorbed, more burping/fishy taste. Always check label. Pay 2× more for rTG, get better outcomes.
Vegan alternatives?
Algae oil — direct DHA + EPA from microalgae (the original source). Per gram: 2-3× cost vs fish oil. Quality: less variation than fish oil. Brands: Nordic Naturals algae, Ovega-3, Testa.
