How do the top whey protein compare head-to-head?
See all side-by-side comparisons between whey protein products.
How does AIScored compare whey protein?
We collect currently available review and product data from public sources to build a complete comparison baseline.
We read every review, check ingredient labels, fillers, and certifications, then generate an unbiased summary.
Products are scored 0-100 across evidence-based categories, making it easy to compare at a glance.
Which whey protein buying guides are available?
Long-tail guides for specific goals in whey protein.
What should you look for when buying whey protein?
Choosing the right whey protein 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.
What is the best whey protein in 2026?
Based on our analysis of 174 products, the top rated whey protein is Optimum Nutrition Gold Standard 100% Whey Protein 2.27kg with a score of 85.0/100.
How many whey protein products have you reviewed?
We have analysed 174 whey protein products, scoring each on effectiveness, ingredient quality, value for money, side effects, and certifications.
