HelloPharmacist Scorecard of Glutamine 300 by PS ProSupps

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

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.

Glutamine 300 contains one active ingredient: L-glutamine, an amino acid that your body naturally produces. It's a powder form, with no inactive fillers or other 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 we hold shows L-glutamine is effective for sickle cell disease. It's rated possibly effective for HIV/AIDS-related wasting, postoperative (after-surgery) recovery, and critical illness from trauma.

The evidence is strongest for sickle cell disease; for the other uses, the data suggests potential 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.

Glutamine is generally well tolerated in healthy adults. The most common side effects from oral use are belching, bloating, constipation, flatulence, nausea, vomiting, diarrhea, gastrointestinal pain, cough, headache, and musculoskeletal pain.

Rare cases of dizziness and headache have been reported, and in two people with bipolar disorder, mania or hypomania occurred at high doses. If you have kidney or liver disease, use glutamine only under medical supervision.

There isn't enough safety data in pregnancy to say whether it's safe or not — talk with your doctor or pharmacist for personalized advice. The same applies to breastfeeding: there's little safety information available, so avoid supplement doses unless your clinician recommends it.

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 (drugs to prevent seizures), double-check this product with your doctor or pharmacist first — glutamine may theoretically reduce their effectiveness, though this hasn't been confirmed in people yet.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Glutamine may help with sickle cell disease and potentially with recovery after surgery or critical illness. If you take an anticonvulsant medication, check with your doctor or pharmacist before starting — there's a theoretical risk it could interfere with seizure control.

Healthy people generally tolerate it well, but those with kidney or liver problems should only use it under medical supervision.
