Best Whey Protein Powders

Every powder here has whey or another dairy protein as its lead protein source, ranked by protein per 100 calories from verified data. Collagen powders are excluded because collagen is not a complete protein.

Rankings recompute automatically as new verified products are added. Tap a column to sort; product lines with multiple flavours show their best scoring flavour.

How this ranking works

Every nutrition value is transcribed from the manufacturer’s published nutrition label and verified by hand, with no third party food databases.
Product lines are ranked, not individual flavours, so one product’s 20 flavours can’t fill the list. Each entry shows its best scoring flavour.
A maximum of two lines per brand keeps the list diverse.
Labels that don’t state sugar or fiber are treated as unknown (never as zero) and are excluded from sugar and fiber rankings.
Want to hit a daily protein target? The Protein Pal app lets you scan any label and track your protein day by day.
