Protein Bars

Guides and comparisons How to compare whey protein products

Protein bars, wafers and snack bars, sold in boxes of 10 to 30 pieces weighing 35 to 85 g each. Compare the protein per bar together with its weight: an 85 g bar with 25 % protein and a 60 g bar with 32 % protein both contain about 20 g. The nutrition table also shows sugars, polyols such as maltitol and fibre per bar and per 100 g. Divide the box price by the number of bars to compare prices per bar.

Frequently asked questions

How much protein is in a protein bar?

It depends on the weight of the bar and its share of protein. An 85 g bar with 25 % protein contains about 21 g, a 60 g bar with 32 % about 19 g. The label states the protein per bar and per 100 g.

What are polyols on a protein bar label?

Polyols such as maltitol or erythritol are sweeteners that replace part of the sugar; the nutrition table lists them under carbohydrates. Products with more than 10 % added polyols carry the statement that excessive consumption may produce laxative effects.

How is a protein wafer different from a protein bar?

A wafer is a light layered biscuit with a protein cream; it is usually smaller than a bar and contains less protein per piece. Compare the protein per piece and per 100 g on the label.
