The following test on Quest protein Bar from Quest Nutrition has been requested by our site and is therefore an independent test. The product has been ordered at a webshop and delivered directly to the laboratory Nutricontrol.


By use of the nitrogen analysis a protein content of 34,8% has been measured. This represents a deviation of +5,5% compared to the specified percentage of 33% on the label. Total carbohydrates are 26,1 g/100g, +53,5% higher than the 17 g/100g stated on the label, but the sugar content is 1,4 g/100g compared with the 2 g/100g stated and gives a difference of -42,9%. The fat content is 7,7 g/100g compared with 11 g/100g on the label, this gives a difference of -30%. Total calories per 100 grams is 325 kcal while 309 kcal is stated. Dietary fiber content is 5,3 g/100g against the stated 23 g/100g, but this could be because the added corn fibers are not measured in the test.
