HelloPharmacist Scorecard of Glutamine Unflavored by BodyTech

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 Aug 6, 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.

This product is pure L-glutamine, an amino acid your body makes naturally and uses for gut and immune function, especially during stress or illness. You're getting one active ingredient with no fillers or other additions — it's just the amino acid itself as a powder.

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 function support.
  • We looked for evidence on: Exercise-induced muscle damage, Athletic performance, Postoperative recovery, Postoperative infection, Wound healing, Critical illness (trauma) — 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 HIV/AIDS-related wasting, Critical illness (trauma), Postoperative recovery.
  • Also on file: Glutamine is rated "Possibly Ineffective" for Athletic performance.

The evidence supports glutamine as effective for sickle cell disease. For HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma, it's rated possibly effective — meaning there's some evidence it may help, but it's not yet definitive.

The data we hold doesn't establish effectiveness for other uses.

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 are gastrointestinal: belching, bloating, constipation, diarrhea, flatulence, nausea, vomiting, and abdominal pain.

Headache and musculoskeletal pain have also been reported. A small number of people have experienced dizziness, and there are two reported cases of mania or hypomania in patients with bipolar disorder, though these are rare.

If you have kidney or liver disease, you should use glutamine only under medical supervision. There isn't enough safety data to recommend supplemental doses during pregnancy — talk with your doctor or pharmacist about whether it's right for you.

The same goes for breastfeeding: there's limited information, so avoid supplement doses unless a clinician advises otherwise.

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.

Double-check this product with your doctor or pharmacist if you take anticonvulsant medications (drugs to prevent seizures) — glutamine may theoretically interfere with how they work, though this hasn't been seen in actual patients yet.

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.

BodyTech Glutamine is most useful if you have sickle cell disease or are recovering from surgery or critical illness. If you take anticonvulsants, check with your doctor or pharmacist before starting it.

Otherwise, it's generally well tolerated, though GI upset is common at higher doses. Have a conversation with your own healthcare provider about whether it fits your situation.

Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this give me stomach problems?
Gastrointestinal side effects are the most common, especially at higher doses. Belching, bloating, diarrhea, nausea, and stomach pain have been reported in trials. Starting with a lower dose and taking it with food may help, but talk with your pharmacist if you're sensitive to supplements.
Is glutamine safe during pregnancy?

What does L-glutamine actually do in my body?
It's an amino acid your body uses for gut health, immune function, and muscle recovery — especially when you're under physical stress like surgery or serious illness. Your body makes its own, but sometimes supplementing it may help depending on your situation.
Is this pure glutamine with no additives?
Yes — this powder is just L-glutamine with no fillers, binders, or other ingredients added.
