HelloPharmacist Scorecard of Glutamine Fruit Punch 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.

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: glutamine, an amino acid your body uses in protein metabolism and immune function. It comes as a powder in fruit punch flavor, with inactive ingredients including citric acid, malic acid, and artificial sweeteners (acesulfame potassium and sucralose) for taste, plus Red Lake #40 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, postoperative recovery, and critical illness from trauma.

The evidence we hold shows promise in these areas, though the strength of proof varies by condition.

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 when taken by mouth, though a number of trial participants experienced stomach upset — belching, bloating, constipation, diarrhea, gas, nausea, vomiting, and abdominal pain are the most common side effects, especially at higher doses. Headache, musculoskeletal pain, and cough have also been reported.

Dizziness has occurred, and two people with bipolar disorder reported mood changes (mania or hypomania) while taking glutamine. The safety data in pregnancy and lactation is rated likely safe, so supplemental glutamine is generally considered appropriate in those settings.

However, if you have kidney or liver disease, use it only under your doctor's supervision. If you're pregnant or breastfeeding and considering glutamine, talk it over with your doctor or pharmacist for personalized advice.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?

  • 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.

Anticonvulsants (seizure medications) are the chief concern — glutamine might blunt their effectiveness. Altogether, these interactions span 50 individual medications.

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 or HIV-related wasting and is generally well tolerated in healthy adults, though digestive upset and headache can happen. The main caution is if you take anticonvulsants — check with your doctor or pharmacist first.

If you have kidney or liver disease, you'll also need medical oversight. Run your medications through the tool on this page before you start.

Glutamine Fruit Punch Flavor by Universal: Common Questions

Does Glutamine Fruit Punch Flavor by Universal interact with any medications?
Yes. Based on its ingredients, Glutamine Fruit Punch 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 Fruit Punch 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 does glutamine do in my body?
Glutamine is an amino acid involved in protein metabolism and immune function. Your body makes it naturally, and it's believed to support recovery after surgery, trauma, or severe illness, as well as help certain conditions like HIV-related wasting.
What side effects should I expect?
Most people experience mild stomach issues — bloating, gas, constipation, or diarrhea — especially at higher doses. Nausea, vomiting, headache, and belching can occur. Dizziness is less common. Digestive effects tend to improve if you lower your dose.
Is it safe if I'm pregnant or breastfeeding?
The safety data is rated likely safe for both pregnancy and lactation, so it's generally considered appropriate. Still, talk with your doctor or pharmacist about whether it's right for your individual situation and needs.
Can I take this if I have kidney or liver problems?
You should only use glutamine under medical supervision if you have kidney or liver disease. Talk with your doctor before starting it.
Does it really work?
It's proven effective for sickle cell disease. For HIV-related wasting, postoperative recovery, and critical illness, the evidence suggests it may help, though the proof isn't as strong as it is for sickle cell.
What's in the powder besides glutamine?
The inactive ingredients are citric acid, malic acid, fruit punch flavoring (natural and artificial), two artificial sweeteners (acesulfame potassium and sucralose), and Red Lake #40 red colorant — all there to make it taste good and mix easily.
