Tagatose (E963): What It Is and Is It Safe?
A naturally occurring rare monosaccharide sugar found in small amounts in dairy products and certain fruits. Approximately 92% as sweet as sucrose but provides only about 1.5 kcal/g due to low intestinal absorption. Has a very low glycaemic index (GI approximately 3). Most ingested tagatose is fermented by colonic bacteria, which is beneficial for gut microbiome diversity but can cause bloating, flatulence, and loose stools at high doses (generally above 30g/day). Does not promote tooth decay and may actively inhibit some oral bacteria.
