HelloPharmacist Scorecard of Glutamine DNA Unflavored by BSN

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, micronized (a finely powdered form for better absorption). Glutamine is an amino acid your body produces naturally and uses for muscle recovery, immune function, and gut health.

The product has no inactive fillers or other ingredients — it's glutamine alone.

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: recovery from intense exercise and muscle protein development.
  • We looked for evidence on: Exercise-induced muscle damage, Athletic performance, Postoperative recovery, Wound healing, Muscle strength, Protein synthesis.
  • 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 supports glutamine for sickle cell disease, where it's rated Effective. For HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma, the evidence is Possibly Effective — meaning there's some promise, but we need more research to be certain.

The data we hold doesn't establish effectiveness for other common uses.

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 are mild GI issues: belching, bloating, constipation, diarrhea, flatulence, nausea, vomiting, and stomach pain — especially at higher doses (10–30 grams daily).

Headache and musculoskeletal pain have also been reported. A small number of people with bipolar disorder experienced mania or hypomania at doses around 4 grams daily.

If you have kidney or liver disease, use this only under medical supervision. Safety data during pregnancy is limited, but existing evidence rates it Likely Safe — still, talk with your doctor before taking it while pregnant.

There isn't enough data to recommend supplemental glutamine while breastfeeding unless your clinician advises it.

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.

Before taking BSN Glutamine DNA, confirm with your doctor or pharmacist if you use anticonvulsant medications (seizure drugs). Glutamine might theoretically reduce their effectiveness, though this hasn't been seen in humans yet.

Also mention any kidney or liver disease, as you'd need medical supervision.
