A typical 1 bar serving of protein bar contains 16.1 grams of protein (30.3 g per 100 g), which makes it a very good source of protein. That covers roughly 32% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Around 29% of the calories in protein bar come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 11 protein supplements in the database, protein bar ranks 7th by protein per serving, and 221st out of all 796 foods on the site. Set against whey protein isolate, another protein supplement entry in the database, a serving carries about 0.6 g less protein (whey protein isolate has 16.7 g per 1 scoop).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is counted by piece at 53 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
Protein bars vary widely by brand. This record describes a typical whey- or milk-protein bar, which is a complete protein; bars built on rice, pea or collagen protein are not. Always check the label of the bar in your hand.
