HelloPharmacist Scorecard of L-Glutamine 5 g Fruit Punch 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, 5 grams per serving. L-glutamine is an amino acid your body uses for muscle and gut health, and it plays a role in immune function and recovery from physical stress.

The inactive ingredients are malic acid, citric acid, natural flavors, beet powder, and sucralose — the typical binders, acids, and sweeteners that give the powder its taste and shelf life.

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).

L-glutamine is effective for sickle cell disease. It's considered possibly effective for HIV/AIDS-related wasting, recovery after surgery, and critical illness from trauma — meaning there's real evidence it may help, but more research would be welcome to be sure.

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 people report are belching, bloating, constipation, diarrhea, flatulence, gas pain, nausea, vomiting, headache, and musculoskeletal pain — mostly mild digestive or head symptoms.

At high doses (10–30 grams daily), nausea, vomiting, and belly pain are more likely. Two patients with bipolar disorder taking up to 4 grams daily have reported mood changes (mania or hypomania), so if you have a mood disorder, mention glutamine to your doctor before starting.

The safety data for pregnancy and breastfeeding is rated as likely safe. However, if you have kidney or liver disease, use this only under medical supervision.

The safety data for breastfeeding is limited, so talk it over with your clinician before taking supplement doses while nursing.

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.

Anticonvulsant medications (seizure drugs) are the main type to double-check before starting. Glutamine may theoretically antagonize how they work.

Talk it over with your doctor or pharmacist if you take any of them.

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 is worth considering if you have sickle cell disease, or possibly if you're recovering from surgery or dealing with wasting related to HIV/AIDS. If you take anticonvulsants, check your specific medications first — the interaction is theoretical but real enough to confirm with your doctor or pharmacist.

In healthy people without seizure drugs or kidney/liver problems, it's generally well tolerated, though digestive upset and headache are common.

Yes. Based on its ingredients, L-Glutamine 5 g Fruit Punch 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?
L-Glutamine 5 g Fruit Punch 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.
Is L-glutamine safe during pregnancy and breastfeeding?

Does L-glutamine actually work?
It's proven effective for sickle cell disease. For HIV/AIDS-related wasting, post-surgery recovery, and trauma recovery, the evidence says it possibly helps, but we'd like more data to be confident.
Can I take this if I have kidney or liver disease?
Only under medical supervision. Talk with your doctor first — they'll know whether it's right for your situation.
I have bipolar disorder — is this safe for me?
Two patients with bipolar disorder taking glutamine up to 4 grams daily reported mood changes. Because of this, mention it to your psychiatrist or doctor before starting.
