Ingredient Quality
Inessa is IFOS 5-Star certified — the highest purity standard in the omega-3 industry, testing for mercury, lead, cadmium, PCBs, and oxidation. Crucially, it uses the triglyceride form (the natural form found in fish), which absorbs roughly 30% better than the cheaper synthetic ethyl ester form most budget brands use. It's sourced from wild anchovies (small, short-lived fish with minimal mercury accumulation) and carries Friend of the Sea sustainability certification.
Value Analysis
At £16.99 for 60 one-a-day softgels, the per-mg EPA+DHA cost is premium, but you're getting 840mg from a single capsule — equivalent to 3–4 standard high-street capsules. Factor in the triglyceride absorption advantage and the value holds up well against cheaper, lower-quality oils.
Effectiveness
840mg EPA+DHA per day comfortably exceeds the NHS 250mg minimum and sits in the range used for cardiovascular and anti-inflammatory benefit. The triglyceride form and patented purification (removing 99.5% of oxidation products) mean better absorption and no fishy aftertaste.
Who Is This Best For?
Anyone who wants the highest-quality, best-absorbed omega-3 with verified purity and sustainability — and the convenience of one capsule a day.

Inessa Advanced Omega-3 FAQ
What's the difference between triglyceride and ethyl ester omega-3?
Triglyceride is the natural form found in fish and absorbs around 30% better. Ethyl ester is a cheaper synthetic form created during concentration. Inessa uses the triglyceride form, which your body recognises as food and absorbs more efficiently.
What does IFOS 5-Star mean?
IFOS (International Fish Oil Standards) is the leading independent testing programme. A 5-star rating means the product passed the strictest tests for potency, purity (mercury, PCBs, dioxins) and oxidation. It's the gold standard for omega-3 quality.
