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.
Weight for weight, protein bar has 2 g of protein for each gram of fat (30.3 g against 15.2 g per 100 g).
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 quoted here is counted by piece at 53 g, and it covers about 32% of the 50 g FDA Daily Value for protein.
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.
