Drug & supplement interaction

Xanthan Gum + Progesterone

Progesterone brand name: Milprosa.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Xanthan Gum and Progesterone in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Xanthan Gum and Progesterone

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Progesterone and Xanthan Gum in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Xanthan Gum safety at a glance

Xanthan Gum overall Generally safe Considered safe for most people in the amounts used in food.
Pregnancy Use caution Food amounts are likely fine, but avoid large supplemental doses without medical advice.
Breastfeeding Use caution Food amounts are likely fine; large doses have not been well studied during breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Progesterone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Progesterone is filed under 3 classifications — including topical drugs, cytochrome p450 3a4 (cyp3a4) substrates. Xanthan Gum has documented interactions with 1 drug class — the most serious being oral drugs (minor) — and none of Progesterone’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Xanthan Gum and Progesterone May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

    Progesterone

    Listed in the ADVERSE REACTIONS section of the FDA label for Progesterone. Read the label on DailyMed ›

Reported for Xanthan Gum but not commonly for Progesterone: an allergic reaction, sore throat and a skin rash.

Effects for Progesterone come from the ADVERSE REACTIONS section of its FDA label; effects for Xanthan Gum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 22,512 voluntary FDA FAERS reports for Progesterone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Everything else you take

See Every Supplement That Interacts With Progesterone

This page covers Xanthan Gum only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Progesterone page lists 126 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate), Adrafinil (moderate) and African Wild Potato (moderate).

By severity: 2 major · 91 moderate · 33 minor.

From our pharmacist’s overview on the Progesterone page

“Many people take progesterone (Milprosa) to support a pregnancy during fertility treatment or as part of hormone therapy, which is exactly when St. John's wort for mood or a morning glass of grapefruit juice can feel harmless.”

About Xanthan Gum

What is Xanthan Gum?

Xanthan Gum
  • Food thickener and stabilizer
  • Bulk-forming laxative
  • Thickening liquids for swallowing problems
  • Gluten-free baking aid
  • Blood sugar support (limited evidence)

Xanthan gum is a fermentation-made fiber widely used to thicken and stabilize foods and to thicken liquids for people with swallowing difficulties. It is generally recognized as safe in the small amounts found in food, but large doses can cause gas, bloating, and loose stools. Talk to your pharmacist or doctor before using it for any medical purpose.

Polysaccharide produced by fermentation of Xanthomonas campestris bacteria · Powder, food additive, capsules; ingredient in thickened liquids and bulk-forming products

An interaction check asks whether these two react with each other — it does not ask whether Xanthan Gum is a good idea for someone in your situation. Here is what our Xanthan Gum record says about it on its own.

Xanthan Gum: dosing

There is no standard medicinal dose of xanthan gum. In foods it is used in very small amounts, and as a liquid thickener it is added to reach a specific thickness recommended by a speech therapist or doctor.If you are using a product that contains xanthan gum, follow the label instructions or the directions given by your health care team.

About Progesterone

What Is Progesterone Used For?

Brand name: Milprosa

Progesterone capsules (including Prometrium) are used to prevent endometrial hyperplasia (abnormal thickening of the uterine lining) in postmenopausal women with a uterus who are taking estrogen, and to treat secondary amenorrhea (missed periods not caused by pregnancy).

Progesterone injection is indicated for amenorrhea and abnormal uterine bleeding caused by a hormonal imbalance. Crinone vaginal gel is used as part of Assisted Reproductive Technology (ART) for progesterone supplementation or replacement, and Crinone 4% is also indicated for secondary amenorrhea. Vaginal inserts — including Endometrin and other progesterone vaginal insert products — are used to support embryo implantation and early pregnancy as part of an ART treatment program for infertile women.

Most-Reported Side Effects for Progesterone

From FAERS, the FDA’s public side-effect reporting system (22,803 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Headache 2,094 reports
Fatigue 1,795 reports
Nausea 1,475 reports

Taking Xanthan Gum and Progesterone Together: Common Questions

Is it safe to take Xanthan Gum with Progesterone?
We do not list a known interaction between Xanthan Gum and Progesterone. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Xanthan Gum and Progesterone have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Xanthan Gum and Progesterone combination checked?
Interactions in our licensed database are recorded against drug classes. Progesterone is filed under 3 classifications, and Xanthan Gum has documented interactions with 1 drug class — none of Progesterone's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Xanthan Gum interact with any other medications?
Yes. Xanthan Gum has 2,022 documented drug interactions in our database — Progesterone is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Progesterone interact with any supplements?
Yes. Progesterone has documented interactions with 126 supplements in our database — Xanthan Gum is not one of them. The Progesterone interaction page linked on this page lists every one, ranked by severity.
