HelloPharmacist Scorecard of Glutamine by ALLMAX

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.

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.

ALLMAX Glutamine contains one active ingredient: L-glutamine, a naturally occurring amino acid your body uses for muscle support and immune function. It comes as a powder with no inactive ingredients listed.

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

This product doesn't appear to be marketed for a specific use, so we graded Glutamine's overall clinical evidence instead.

Strong

Strong clinical evidence supports Glutamine for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Sickle cell disease — rated "Effective" (Natural Medicines).
  • On file: HIV/AIDS-related wasting — rated "Possibly Effective" (Natural Medicines).
  • On file: Critical illness (trauma) — rated "Possibly Effective" (Natural Medicines).
  • On file: Postoperative recovery — rated "Possibly Effective" (Natural Medicines).
  • On file: Pancreatitis — rated "Possibly Effective" (Natural Medicines).

The data supports L-glutamine as effective for sickle cell disease. It's rated possibly effective for HIV/AIDS-related wasting, recovery after surgery, and critical illness from trauma.

For other uses, the evidence isn't established in the data we hold.

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 digestive — belching, bloating, gas, constipation, diarrhea, nausea, and stomach pain.

Headache and musculoskeletal pain have also been reported. A small number of people have experienced dizziness; one case resolved when the dose was lowered.

Two people with bipolar disorder reported mood changes (mania or hypomania) on high doses, so if you have a mood disorder, mention this supplement to your doctor. If you have kidney or liver disease, use this only under medical supervision.

There isn't enough safety data during pregnancy and breastfeeding, so talk with your doctor or pharmacist before taking it if you're pregnant or nursing.

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), check with your pharmacist before using this product. The interaction is theoretical and not yet reported in humans, but your doctor should know you're taking it.

Formula

ALLMAX Glutamine uses glutamine crystals made from a natural fermentation process. This state-of-the-art process creates a unique, purified and isolated glutamine ideal for supplementation. Glutamine is the most abundant amino acid found in muscle tissue. During times of stress, including exercise and athletic events, glutamine is one of the first amino acids to be oxidized. Supplementation with glutamine may help to support muscle glutamine levels, prevent muscle tissue breakdown and increase recovery.

OU (Kosher) Certified

Fermentation derived glutamine

Formulation

The Glutasure advantage: ALLMAX Glutamine uses a proprietary hyper-particulation process called Glutasure technology. Glutasure is a pressure driven ceramic membrane process that: 1) Decreases glutamine particle size 2) Increases glutamine suspension time in liquid 3) Speeds glutamine absorption into the bloodstream

Clean for athletes, banned substance free. This product contains no WADA banned ingredients. This is validated by in-market random testing managed by an independent 3rd party - Informed Choice. Test result details can be viewed at www.CleanForAthletes.com.

Glutamine by ALLMAX: Common Questions

Does Glutamine by ALLMAX interact with any medications?
Yes. Based on its ingredients, Glutamine has a known interaction with 50 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Glutamine contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
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's L-glutamine and what does it do?
It's an amino acid your body naturally makes and uses for muscle support and immune function. This supplement provides extra amounts — it's used mainly for sickle cell disease, recovery after surgery, and critical illness.
What side effects might I get?
Digestive issues are most common: bloating, gas, nausea, diarrhea, and stomach pain. Headache and muscle aches have been reported too. Taking less than the high doses tested may reduce these.
Is it safe during pregnancy or breastfeeding?
There isn't enough data to say either way. Talk with your doctor or pharmacist for personalized advice before using it if you're pregnant or nursing.
I have liver disease — can I take this?
You should only use it under medical supervision. Talk to your doctor first.
Does it really work for sickle cell disease?
Yes — the evidence rates it as effective for that. For other conditions like post-surgery recovery, it's possibly effective, meaning there's some evidence but it's not as strong.
