I saw the post from 2022 regarding Biotene spray (https://kashrut.org/biotene-dry-mouth-spray/; https://www.biotene.com/dry-mouth-products/moisturizing-mouth-spray/), but am more interested in the lozenges (https://www.biotene.com/dry-mouth-products/lozenges/).

Ingredients are isomalt, xylitol, water, glycerin, sodium citrate, natural and artificial flavor, pectin, sucralose, FD&C blue 1.

They are surprisingly pleasant to consume, in addition to the medical / palliative benefits they provide.

I understand that both isomalt and xylitol are sugar alcohols, with some being produced from “agricultural waste from processing maize, wheat, or rice.” Do they pose a concern for Pesah?

Similarly, are there any concerns with the “natural flavors”, whether for Pesah or otherwise?

Thank you in advance, Richard
