Protein Pal Analysis

Protein Source

Where the 20g of protein comes from, largest contributor first

Milk Protein Isolate
Complete

Complete protein. Roughly 80% casein and 20% whey, so it digests slower than whey alone.

Whey Protein Isolate
Complete

Complete protein, fast absorbing. Filtered to remove most of the lactose and fat.

Whey Protein Concentrate
Complete

Complete protein, fast absorbing. The least processed whey, with more lactose and fat than isolate.

Peanut Flour
Incomplete

Defatted peanuts, roughly half protein by weight. Low in methionine.

Milk Protein Concentrate
Complete

Complete protein. Roughly 80% casein and 20% whey, so it digests slower than whey alone.

Hydrolysed Whey
Complete

Complete protein. Whey that has been pre broken down, making it the fastest absorbing form.

Also Contains

Sugar Alcohols

  • Glycerin

    Chemically a sugar alcohol, used to keep bars soft and moist rather than to sweeten. The EU safety authority found no safety concern at food levels. Large amounts can draw water into the gut and have a laxative effect.

    EFSA re-evaluation of glycerol E422 (2017)
  • Maltitol

    A sugar alcohol that does raise blood glucose, with a glycaemic index around 35 where most polyols are near zero. It is the usual cause of the digestive complaints from protein bars: bloating, gas and a laxative effect, typically above roughly 30 to 40g a day.

    Livesey, Nutrition Research Reviews (2003)

Tropical Oils

  • Palm Kernel Oil

    Pressed from the fruit of the oil palm rather than its seed, so it is not one of the seed oils. Around half saturated fat, mostly palmitic acid, and a meta-analysis of controlled trials found it raises LDL cholesterol compared with vegetable oils low in saturated fat. Palm kernel oil comes from the seed inside the same fruit and carries more saturated fat again. Both stay solid at room temperature without hydrogenation, which is why coatings use them.
