What should you look for when buying omega-3 & fish oil?
Choosing the right omega-3 & fish oil can be overwhelming with hundreds of options on the UK market. Here are the key factors we analyse when scoring each product:
Bioavailability & Forms
Not all ingredient forms are equally effective. We check which forms are used and whether they're backed by research for optimal absorption and bioavailability.
Clean Label & Fillers
Many products contain unnecessary fillers, artificial colours, added sugars, and bulking agents. We flag products with excessive additives and reward clean formulations.
Third-Party Testing
Independent lab testing verifies that what's on the label is actually in the product. Products with third-party certifications (NSF, USP, Informed Sport) score higher in our rankings.
Value per Serving
The cheapest option isn't always the best value. We calculate the cost per serving and weigh it against ingredient quality, dosage, and overall effectiveness reported by users.
How Our Scoring Works
Each product is scored 0-100 across evidence-based categories. An overall score of 80+ indicates a product we'd recommend to most people. Scores of 60-79 are solid choices with some trade-offs, while anything below 60 has significant drawbacks reported by users. Our scores are recalculated regularly as new reviews and ingredient data come in.
Frequently Asked Questions
Where do you get your reviews?
We aggregate publicly available review and product data from retailer pages, communities, and specialist sources. We do not use manufacturer-provided testimonials as evidence.
How often are scores updated?
We re-analyse reviews and update scores regularly. Product pages show the date of the latest analysis.
Do you receive products for free?
No. AIScored does not accept free products or sponsored placements. Our revenue comes from affiliate links, which do not influence our scores.
