“Xanthan Gum?”Here!a plant-fermented thickener
Hasn’t appeared in a scanned product yet.
In personal care
Xanthan gum is a polysaccharide produced by fermenting sugar with the bacterium Xanthomonas campestris, then purifying the resulting gum.
Why it’s used
It thickens and stabilizes formulas, helping keep oil and water phases from separating and giving lotions, gels, and serums their texture.
What the evidence says
We haven’t found a source for this one that you can open and check, so we’re not summarizing the evidence.
Look it up yourself
We would rather point you at the shelf than summarize something you can’t check. These are the same places we search:
- PubChem — what the substance is, chemically — names, synonyms and structure
- PubMed — every paper indexed by the US National Library of Medicine that names it
These are starting points, not our findings — we haven’t run them for you. A substance whose name is also an ordinary word (“Heart”, “Alanine”, “Water”) will return papers that are not about the ingredient at all.
Rumors
Xanthan gum can cause skin reactions in people allergic to corn, soy or wheat.

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.
