Protein bar rankings

Protein bars with the most protein, across every brand

If a bar is standing in for a meal or a post-workout shake, total protein per bar is what you're buying. This table ranks every flavor we track by grams of protein on the label, with calories next to it so you can see what the protein costs you. Ties break by fewer calories.

Questions people ask

What's the most protein in a protein bar?

Among the bars we track, the top of the table — the label with the highest protein per bar. Mainstream bars top out around 20–28 g; above that you're usually looking at a larger, higher-calorie bar.

Is 20 g of protein in a bar a lot?

It's the common target for a 'protein bar' and roughly the protein in three eggs. Whether it's 'a lot' depends on the calories it comes with — see the most-protein-per-calorie ranking.

Where can I buy these bars?

Every row links to a search for that exact flavor on eBay, where sellers list single bars and boxes; the brand pages add Amazon links. We may earn a commission at no cost to you.
