What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

MucosaQOL Peach Flavor is a single-ingredient powder: L-glutamine, an amino acid (a building block of protein) your body uses to support gut lining health and immune function. The powder also contains stevia extract for sweetness and peach flavoring.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Promotes healthy oral and GI mucosal function.
  • We looked for evidence on: Oral mucositis, Chemotherapy-induced diarrhea, Radiation-induced diarrhea, Radiation-induced esophagitis, Crohn disease, Irritable bowel syndrome (IBS) — and 4 related terms.
  • The strongest evidence on file: Glutamine is rated "Possibly Effective" for Postoperative recovery (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Ineffective" for Crohn disease, Radiation-induced diarrhea.
  • Also on file: Glutamine is rated "Insufficient Reliable Evidence To Rate" for Chemotherapy-induced diarrhea, Irritable bowel syndrome (IBS), Oral mucositis, Peptic ulcers.

L-glutamine is rated Effective for sickle cell disease. It's rated Possibly Effective for HIV/AIDS-related wasting, postoperative (after-surgery) recovery, and critical illness from trauma.

The evidence supporting these uses varies — sickle cell disease has the strongest data behind it.

The evidence, ingredient by ingredient Glutamine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-glutamine is generally well tolerated in healthy adults. However, if you have kidney or liver disease, use it only under medical supervision.

There isn't enough reliable safety data on supplement doses during pregnancy or breastfeeding — talk with your doctor or pharmacist before taking it if you're pregnant or nursing. Common side effects from oral glutamine include belching, bloating, constipation, nausea, vomiting, diarrhea, stomach pain, headache, and cough.

High doses (10–30 grams daily in clinical trials) are more likely to cause gastrointestinal upset. Rarely, dizziness has been reported; in one case, lowering the dose resolved it.

Two people with bipolar disorder reported mood changes (mania or hypomania) while taking glutamine; if you have bipolar disorder, discuss this product with your doctor first.

Side effects, ingredient by ingredient Glutamine

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Glutamine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: seizure medications.
  • For scale: 50 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take anticonvulsant medications (seizure drugs), check with your doctor or pharmacist before using this product. The interaction is Moderate and involves glutamine potentially working against how your medication prevents seizures.
