HelloPharmacist Scorecard of Gluta Alkaline Unflavored by BPI Sports

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.

Gluta Alkaline Unflavored contains one active ingredient: glutamine, an amino acid your body uses for muscle recovery, immune function, and gut health. The product also contains inactive ingredients—buffering agents, sweeteners (sucralose and acesulfame-K), citric acid, silica, taurine, and food coloring—that make up the powder base.

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 recovery and anabolic support.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Wound healing, Critical illness (trauma), HIV/AIDS-related wasting — and 4 related terms.
  • The strongest evidence on file: Glutamine is rated "Possibly Effective" for HIV/AIDS-related wasting (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Effective" for Critical illness (trauma), Postoperative recovery.
  • Also on file: Glutamine is rated "Possibly Ineffective" for Athletic performance, Burns.

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

If you're considering this supplement for one of those conditions, talk with your doctor about whether it fits your treatment plan.

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 in healthy adults. The most common side effects are gastrointestinal: belching, bloating, constipation, diarrhea, flatulence, nausea, vomiting, and stomach pain.

Headache and musculoskeletal pain have also been reported. A small number of cases mention dizziness that resolved when the dose was lowered, and rare cases of mania or hypomania in people with bipolar disorder taking high doses.

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 or breastfeeding unless your doctor advises 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 drugs), check your specific prescriptions with the tool on this page before using this product. Glutamine may theoretically reduce how well these medications work, though this hasn't been confirmed in patients.

In fact, researchers are now suggesting that Glutamine might be the most important of all amino acids – as it provides a component in muscle metabolism and cellular support not shared by any other single amino acid(R). For optimal nutrient uptake, the patent-pending pH Balanced Alkaline Buering System pH-Sorb(TM) has been added, which is designed to directly influence the acidity levels of the stomach for optimal digestion.

General Statements

L-Glutamine and Trans-Alanyl-Glutamine: Studies show that Glutamine plays a role in protein synthesis, and at the same time promotes an anabolic state by down-regulating catabolic activity.

Do not exceed recommended dose.
