Protein Powder ranked by protein density

Showing the top 50 of the 843 protein powder products that carry a comparable calorie figure, ranked by protein per 100 calories. Figures per label, sourced from Open Food Facts and tracker user logs, last checked 2026-09-18.

What the protein powder numbers show

Median across all 843 of them is 19.6g of protein per 100 calories. 801 clear 10g of protein per 100 calories — most of them, and 10g is the line Keith uses for a food that pays for its calories.

Calories run from 27 to 470 per 100g inside this one group, an 18-fold spread, so “protein powder” on its own tells you almost nothing about what a portion costs you.

This is a name-brand group: only 1 of the 843 are supermarket own-label, too few to compare the two fairly.

What to actually pick

Most of this group already clears the benchmark, so the decision is price and taste rather than macros. Starlabs Whey isolac choco tops the table at 25.2g of protein per 100 calories.

31 of the 843 carry 400 calories or more per 100g — the ones worth weighing rather than eyeballing.

Where this fits

A protein-per-calorie number is only useful once you know the target, and that is how much protein a day actually works out to.

For one specific product rather than the whole group, the 20,000-product database is searchable on Calories in Ireland, and the same figures are built into the calorie app.
