HelloPharmacist Scorecard of L-Glutamine 5 g Blue Raspberry by Nutricost

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.

This product contains one active ingredient: L-glutamine, an amino acid your body naturally makes and uses for gut function, immune health, and muscle recovery. The 5-gram serving also includes inactive ingredients — malic acid, citric acid, natural flavors, sucralose, and blue spirulina — that help flavor and preserve the powder.

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 evidence we hold shows L-glutamine is effective for sickle cell disease. It's rated possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma — meaning there's some promising research, but we need more solid data to be fully confident.

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. Common side effects are mostly digestive — belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting.

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

There isn't enough reliable safety data to recommend supplemental doses during pregnancy or breastfeeding unless your doctor or pharmacist advises otherwise.

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.

The main medication type to double-check before starting this product is anticonvulsants (drugs that prevent seizures). The interaction is theoretical but documented as Moderate severity.

Use the search tool on this page to confirm your specific medication, then talk it over with your own doctor or pharmacist.

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.

L-glutamine may be worth considering if you have sickle cell disease or are recovering from surgery or critical illness, and if the evidence for your specific situation interests you. If you take anticonvulsant medications, check with your own doctor or pharmacist first.

Otherwise, it's generally well tolerated in healthy people, though digestive upset is common at higher doses.
