Is Barebells Protein Bar low FODMAP?

FODMAP score

High FODMAP

No — Barebells is a high-FODMAP bar, and maltitol is the reason. It's the bar's primary bulk sweetener, and maltitol is among the most poorly absorbed polyols, with polydextrose and glycerin adding further fermentable load. The milk proteins are mostly low-lactose, so it's the sweetener system, not the dairy, that drives the verdict.

What's inside

MaltitolThe main sweetener and a poorly absorbed polyol — the single biggest reason for the high verdict.

PolydextroseA synthetic fermentable fiber that adds osmotic and gas-producing load on top of the maltitol.

GlycerinA humectant that contributes to the overall polyol-style load.

Milk protein blend (caseinate, whey concentrate, whey isolate)Caseinate and isolate are low in lactose, but the whey protein concentrate portion carries some.

SucraloseA non-fermentable high-intensity sweetener — not a FODMAP concern.

📏 A full 55g bar delivers a multi-gram maltitol dose; even half a bar carries enough polyol to matter for sensitive eaters.
