Igennus Healthcare Nutrition Pure & Essential Omega-3 Wild Fish Oil

Frequently asked questions

What does IFOS 5-star certification actually mean?

IFOS (International Fish Oil Standards), run by Nutrasource, tests each batch of fish oil against four criteria — PCB/dioxin levels, heavy metals, oxidation (freshness, measured via peroxide and anisidine values), and label-claim potency. A 5-star rating means the batch clears all four at the strictest thresholds. Certificates are publicly searchable on the IFOS website.

What is re-esterified triglyceride (rTG) form and why does Igennus use it?

Fish oil naturally occurs as triglycerides. To concentrate EPA/DHA, manufacturers convert it to ethyl ester first; rTG form re-attaches the fatty acids to a glycerol backbone after concentration. Research suggests rTG absorbs somewhat better than ethyl ester, though differences vs natural TG are modest. Igennus positions its whole range around this form.

Where can I buy Igennus Pure & Essential Omega-3 in the UK?

Listed at Amazon UK and direct from igennus.com — both at £34.99 at the time of last check. Pick on delivery preference and returns policy.

How does this compare to Igennus's Pharmepa range?

Pure & Essential is the general-purpose, balanced-omega-3 product. Pharmepa RESTORE and Pharmepa COMPLETE are the high-EPA, clinical-tier SKUs in the same range. All three are rTG-form and IFOS 5-star certified — the difference is EPA:DHA ratio and the loading regimen.

Why prefer wild fish oil over farmed?

Wild fish (sardine, anchovy, mackerel) typically come from established sustainable fisheries and have a different fatty-acid profile than farmed salmon, which is fed pellets. IFOS testing covers the actual contamination outcome regardless of source — wild positioning is more about provenance than safety, since the certificate verifies measured contaminant levels.
