Is Built Bar Protein Bar low FODMAP?

FODMAP score

Moderate

Mostly OK in moderation — Built Bar lands in moderate territory. The protein is nearly lactose-free whey isolate and the coating is real sugar-sweetened dark chocolate, but erythritol plus glycerin gives each bar a meaningful polyol-style load. One bar is manageable for many people; that sweetener stack is why it isn't a clean low pass.

What's inside

ErythritolThe main sugar-free sweetener; a polyol that can pull water into the gut, though it's better absorbed than maltitol.

GlycerinAn osmotic humectant that adds to the polyol-style load in sensitive people.

Digestion-resistant maltodextrinA processed soluble fiber that is largely low FODMAP, though ~6g of added fiber per bar can still produce some gas as it ferments.

Whey protein isolateIsolate is nearly lactose-free, so the dairy protein isn't the issue.

Dark chocolate coating (sugar-sweetened)The coating uses regular chocolate with cane sugar, not maltitol-based sugar-free chocolate.

📏 One bar at a time — a second bar in the same day quickly stacks the erythritol and glycerin doses.
