HelloPharmacist Scorecard of Glutamine Micronized Unflavored by Dymatize

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 produces. There are no inactive ingredients listed for this powder.

L-glutamine plays a role in immune function, gut health, and muscle recovery, and your body's own supply is drawn from dietary protein and muscle tissue. This single-ingredient format lets you control the dose and mix it into beverages or food as you prefer.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: muscle support and athletic performance.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Wound healing, muscle strength, recovery.
  • The strongest evidence on file: Glutamine is rated "Possibly Effective" for Postoperative recovery (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Ineffective" for Athletic performance.
  • Also on file: Glutamine is rated "Insufficient Reliable Evidence To Rate" for Wound healing, Exercise-induced muscle damage.

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.

That means there's some evidence it may help in those situations, but it's not as strong or consistent as the sickle cell data. If you're considering glutamine for a specific condition, talk it over with your doctor to see whether the evidence fits your situation.

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.

Orally, L-glutamine is generally well tolerated in healthy adults. The most common side effects are gastrointestinal ones — belching, bloating, constipation, diarrhea, flatulence, nausea, vomiting, and abdominal pain.

Headache and musculoskeletal pain have also been reported. Dizziness and headache can occur, though one patient's dizziness resolved after the dose was cut in half.

If you have kidney or liver disease, use glutamine only under a doctor's supervision. There isn't enough safety data to recommend supplemental doses during pregnancy or breastfeeding unless your doctor advises it.

People with bipolar disorder should be aware that glutamine has been linked to mania or hypomania in rare cases.

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.

Check with your doctor or pharmacist before taking this product if you use anticonvulsant medications (drugs to prevent or control seizures). Glutamine is theoretically thought to work against how these drugs function, though this hasn't been reported in actual patients yet.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Glutamine is a single-ingredient amino acid supplement backed by solid evidence for sickle cell disease and promising evidence for wasting related to HIV/AIDS and recovery from surgery or critical illness. It's generally well tolerated, though GI side effects are common.

If you take anticonvulsant medications or have kidney or liver disease, talk with your doctor or pharmacist before starting.
