Roll Call does not check drug interactions or assess personal safety.

A polysaccharide produced by fermenting sugar with the bacterium Xanthomonas campestris, then purifying and drying the resulting gum into a powder.

Why it’s used

Used in supplement products as a thickening and stabilizing agent, giving liquids, gummies, and suspensions a consistent texture and keeping ingredients from separating.

What the evidence says

It is a manufacturing ingredient rather than something taken for a health effect, so there is no efficacy question to answer. It has long-standing regulatory recognition as safe for food and supplement use at the small amounts typically used as a thickener.
