Is E966 OK for SIBO?
No, and here is why
The SIBO rule set applies the same FODMAP scan, so e966 flags identically. Munchable also carries a standing note that no SIBO-specific diet has a strong evidence base.
On a real product, the reason Munchable shows reads: High FODMAP polyols as a main ingredient
What it is called on a label
E966 is also printed as lactitol, and as E966. Munchable recognises all of these as the same ingredient, which is the point of scanning rather than reading: the wording changes between brands and the rule does not.
What Munchable checks for SIBO
- The full FODMAP scan: fructans, GOS, polyols, excess fructose and lactose
- Whether each source is a main ingredient or a minor one
- A standing banner on every SIBO verdict about the state of the evidence
The full reasoning, and the evidence behind it, is in the SIBO guide.

The catch with reading labels yourself
Knowing that E966 is a problem is the easy part. Finding it is the hard part: it hides behind wordings that do not look like it, it matters more near the top of the list than the bottom, and a product you have bought for years quietly reformulates. That is the job Munchable does in the aisle, in about a second, from the barcode.
Check it in the shop, not at home
