HelloPharmacist Scorecard of 100% Pure Glutamine 3000 Milligrams by NutraBio

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 11, 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 a single active ingredient: L-glutamine at 3,000 milligrams per serving. Glutamine is an amino acid — one of the building blocks your body uses to make and repair protein.

The capsule itself is made from vegetable material.

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 growth and recovery support.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Wound healing, Burns, 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, Burns, Muscular dystrophy.

The evidence we hold shows glutamine is effective for sickle cell disease. For HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma, the evidence is considered possibly effective — meaning there's some promise, 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.

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

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

The safety data in pregnancy and breastfeeding is limited; the rating is "likely safe," but talk with your doctor or pharmacist before taking it if you're pregnant or nursing.
