HelloPharmacist Scorecard of Gluta Lean Recovery by Labrada

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 naturally uses. It has no inactive ingredients listed.

Glutamine plays a role in muscle recovery, immune function, and gut health, which is why it's popular among people training hard or recovering from illness.

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 protein synthesis support.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Critical illness (trauma), HIV/AIDS-related wasting, Muscular dystrophy — 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, Radiation-induced diarrhea.

The data supports L-glutamine as effective for sickle cell disease. It's rated possibly effective for recovery after surgery, critical illness from trauma, and HIV/AIDS-related wasting — meaning some evidence exists, but more research is needed to be certain.

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 mild digestive complaints: belching, bloating, flatulence, nausea, constipation, diarrhea, and gastrointestinal pain.

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

The safety data during pregnancy and lactation is rated as likely safe, but if you're pregnant or breastfeeding, talk with your doctor or pharmacist before starting — there isn't extensive research on supplement doses in these situations. People with bipolar disorder should be aware that a few cases of mania or hypomania have been reported with high doses; if you have a mood disorder, check with your doctor before using this product.

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), confirm with your doctor or pharmacist before starting this product — glutamine might theoretically interfere with how they work, though it hasn't been observed in patients yet.
