HelloPharmacist Scorecard of Glutamine Blue Raspberry Flavor by Universal

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.

This product is pure glutamine, an amino acid your body makes and uses naturally. Glutamine plays a role in immune function, gut health, and muscle recovery, especially after surgery or during serious illness.

The powder also contains inactive ingredients for flavor and sweetness: natural and artificial blue raspberry flavoring, citric acid, malic acid, acesulfame potassium, sucralose, and FD&C Blue #1 colorant.

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).

Glutamine is effective for sickle cell disease. It's possibly effective for HIV/AIDS-related wasting, recovery after surgery, and critical illness from trauma.

The evidence for those uses shows promise but isn't as strong as for sickle cell disease. If you're considering it for another reason, that data isn't on file here.

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 by healthy adults. The most common side effects from oral use are gastrointestinal: belching, bloating, constipation, flatulence, nausea, vomiting, diarrhea, and abdominal pain.

Headache and musculoskeletal pain have also been reported. A small number of people with bipolar disorder experienced mania or hypomania at higher doses, and one case of dizziness resolved when the dose was lowered.

If you have kidney or liver disease, use glutamine only under medical supervision. There isn't enough safety data to recommend supplemental doses during pregnancy — talk with your doctor for personalized advice.

The same goes for breastfeeding: safety data is limited, so check with your clinician before taking 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 (seizure preventers), double-check with your doctor or pharmacist before using this product — glutamine may theoretically oppose their effects, though this hasn't been seen in actual patients. No other medication interactions are documented for the ingredients we could check.

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 possibly aids recovery after surgery or during critical illness. If you take anticonvulsants, check with your doctor or pharmacist before starting — the interaction is theoretical but flagged as moderate concern.

Healthy adults tolerate it well, but people with kidney or liver disease need medical oversight. Have a conversation with your own doctor or pharmacist about whether it fits your situation.

Glutamine Blue Raspberry Flavor by Universal: Common Questions

Does Glutamine Blue Raspberry Flavor by Universal interact with any medications?
Yes. Based on its ingredients, Glutamine Blue Raspberry Flavor 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 Blue Raspberry Flavor 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 side effects should I watch for?
Most people experience mild gastrointestinal effects: bloating, gas, nausea, or diarrhea, especially at higher doses. Headache and muscle pain have been reported too. If you notice dizziness, reduce your dose and talk to your pharmacist.
Is it safe to take while pregnant or breastfeeding?
The data shows glutamine is likely safe in pregnancy, but there isn't enough information about breastfeeding to be certain either way. Talk with your doctor or pharmacist about what makes sense for your situation.
Can I take this with kidney or liver problems?
Only with medical supervision. If you have kidney or liver disease, check with your doctor first — your body processes glutamine differently and may need a tailored dose or closer monitoring.
Does glutamine actually work for muscle recovery?
We have evidence it helps after surgery and during critical illness, and it's possibly effective for those uses. Data on general muscle recovery from exercise isn't on file here, so ask your doctor if it fits your goal.
How much should I take?
Clinical trials used 10–30 grams daily to treat sickle cell disease, split into two doses, though some studies used 5–15 grams twice daily. Follow the label or your doctor's guidance — the right dose depends on why you're taking it.
