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 Jul 30, 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 contains one active ingredient: L-glutamine, an amino acid your body produces naturally. Glutamine plays a role in muscle recovery, immune function, and gut health.

The powder form lets you mix it into beverages or food to get your dose. There are no inactive ingredients listed for this product.

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: muscle recovery and function support.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Wound healing, Critical illness (trauma), HIV/AIDS-related wasting — and 4 related terms.
  • The strongest evidence on file: Glutamine is rated "Possibly Effective" for HIV/AIDS-related wasting (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 Athletic performance, Muscular dystrophy.

The evidence supports glutamine for sickle cell disease—it's rated effective for that use. For HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma, the evidence is promising but not yet conclusive (rated possibly effective).

The facts don't show effectiveness data for other common uses you might see advertised.

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.

Glutamine is generally well tolerated in healthy adults. The most common side effects are gastrointestinal—belching, bloating, constipation, diarrhea, flatulence, nausea, vomiting, and GI pain.

Headache and musculoskeletal pain have also been reported. If you have kidney or liver disease, use it only under medical supervision.

Pregnancy and lactation data show glutamine is likely safe, though safety information for supplement doses while breastfeeding is limited—talk with your doctor or pharmacist before using it during that time. Two cases of mania or hypomania have been reported in people with bipolar disorder taking up to 4 grams daily, so those with a bipolar diagnosis should check with their own healthcare provider 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 anticonvulsants (seizure medications), double-check with your pharmacist before starting this product. Glutamine may theoretically reduce how well these drugs work, though this hasn't been confirmed in human use yet.

The bottom line

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