HelloPharmacist Scorecard of SuperGLU by Syntrax

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 17, 2026

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.

SuperGLU is a single-ingredient powder containing L-glutamine, an amino acid (a building block your body uses to make proteins). That's all there is to the active ingredient — no fillers or other active compounds added.

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: muscle recovery and immune support.
  • We looked for evidence on: Exercise-induced muscle damage, Postoperative recovery, Critical illness (trauma), Oral mucositis, Chemotherapy-induced diarrhea, Radiation-induced diarrhea — and 4 related terms.
  • The strongest evidence on file: Glutamine is rated "Effective" for Sickle cell disease (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Effective" for Critical illness (trauma), Postoperative recovery.
  • Also on file: Glutamine is rated "Possibly Ineffective" for Radiation-induced diarrhea.

Glutamine is rated effective for sickle cell disease. It's rated possibly effective for HIV/AIDS-related wasting, postoperative recovery (healing after surgery), and critical illness from trauma.

The evidence we hold doesn't cover other uses you might see claimed for glutamine supplements.

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. The most common side effects from oral doses are belching, bloating, constipation, cough, diarrhea, flatulence, gastrointestinal pain, headache, musculoskeletal pain, nausea, and vomiting — mostly digestive complaints, especially at higher doses (10–30 grams daily).

If you have kidney or liver disease, use this supplement only under medical supervision. Pregnancy and lactation data rates glutamine as likely safe, but there isn't enough reliable safety information for supplemental doses while breastfeeding unless your doctor recommends it.

A small number of people with bipolar disorder taking glutamine have reported mania or hypomania; if you have a mood disorder, check with your doctor or pharmacist before starting.

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.

Anticonvulsants (seizure medications) are the main concern — glutamine might theoretically reduce how well they work, though this hasn't been seen in actual patients yet. Check your exact medications and any neurological conditions with your doctor or pharmacist before taking SuperGLU.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

SuperGLU may help with sickle cell disease or recovery from surgery and critical illness, though the evidence for those last two is still developing. If you take any anticonvulsant medication or have kidney or liver disease, talk with your doctor or pharmacist before adding this — the same goes if you have bipolar disorder or are breastfeeding.

Formula

SuperGLU is an ultra-pure, micronized glutamine powder that solves all of the issues facing other glutamines on the market. By containing 100% natural glutamine powder, SuperGLU eliminates the unknown and harmful impurities associated with synthetic glutamine.

Glutamine is the most abundant free amino acid in the body and is present in high concentrations in the immune system, digestive tract and muscle cells. Over time, however, these glutamine levels can be depleted by strenuous exercise, infections, injuries and prolonged stress. Each 5 gram serving of SuperGLU disperses and suspends instantly in solution and helps to restore the body's diminished reserves of glutamine, providing optimal health and muscle recovery.
