HelloPharmacist Scorecard of Glutamine1000 by Evlution Nutrition

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.

Glutamine1000 contains one active ingredient: L-glutamine, a naturally occurring amino acid. The capsule also includes inactive ingredients—microcrystalline cellulose, hypromellose, magnesium stearate, and silica—which are fillers and binders.

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: support glutamine levels during and after exercise.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, muscle recovery, nitrogen balance.
  • The strongest evidence on file: Glutamine is rated "Possibly Effective" for Postoperative recovery (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Ineffective" for Athletic performance.
  • Also on file: Glutamine is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle damage.

L-glutamine is rated effective for sickle cell disease. For HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma, it's rated possibly effective, meaning the evidence suggests a benefit but isn't conclusive yet.

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

Headache and musculoskeletal pain have also been reported. Rare cases of dizziness and mood changes (mania or hypomania) have occurred, mostly in people with bipolar disorder or at higher doses.

If you have kidney or liver disease, use this supplement only under medical supervision. The safety data in pregnancy is rated likely safe.

However, there isn't enough reliable safety information during breastfeeding, so talk with your doctor or pharmacist before taking it while nursing.

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 medication (seizure drugs), double-check your specific medication before using this product—glutamine may theoretically interfere with how they work. No other medication types are documented as interacting with L-glutamine in our data.

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.

Glutamine1000 may be worth considering if you have sickle cell disease, are recovering from surgery, or have HIV/AIDS-related wasting—though the evidence for those last two is still developing. If you take an anticonvulsant medication for seizures, check with your doctor or pharmacist before starting.

Generally well tolerated, but watch for stomach upset and talk with your healthcare provider if you have kidney or liver disease.

How can one product interact with so many drugs?

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.
What is L-glutamine and what does it do in my body?
L-glutamine is an amino acid your body naturally produces and uses. It plays roles in immune function, gut health, and muscle recovery, which is why it's used in supplements to support those areas.
Is this supplement safe if I'm pregnant or breastfeeding?
During pregnancy, L-glutamine is rated likely safe. If you're breastfeeding, there isn't enough safety data to know either way—talk with your doctor or pharmacist for personalized advice before taking it.

Is glutamine effective for muscle building or recovery?

Can I take this if I have kidney or liver disease?
If you have either of these conditions, only use this supplement under your doctor's supervision. Your healthcare provider needs to weigh the benefits and risks for your specific situation.
How much glutamine should I take?
The product facts don't specify a recommended dose. Follow the label instructions or talk with your doctor or pharmacist to figure out what's right for you.
