Protein Powders Buying Guide — What to Look For
Choosing the right protein powders can be overwhelming with hundreds of options on the UK market. Here are the key factors our AI analyses when scoring each product:
Bioavailability & Forms
Not all supplement forms are created equal. For example, magnesium glycinate absorbs much better than magnesium oxide. We check which forms are used and whether they're backed by research for optimal absorption.
Clean Label & Fillers
Many supplements contain unnecessary fillers, artificial colours, added sugars, and bulking agents. Our AI flags products with excessive additives and rewards clean formulations.
Third-Party Testing
Independent lab testing verifies that what's on the label is actually in the bottle. Products with third-party certifications (NSF, USP, Informed Sport) score higher in our rankings.
Value per Serving
The cheapest bottle 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 1-10 across six categories. An overall score of 8+ indicates a product we'd recommend to most people. Scores of 6-7 are solid choices with some trade-offs, while anything below 6 has significant drawbacks reported by users. Our scores are recalculated regularly as new reviews come in.
