HelloPharmacist Scorecard of Gluta-Lyn 1500 Powder by Sci-Fit

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 30, 2026

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-Lyn 1500 Powder has one active ingredient: glutamine (in the form GlutaLean®). Glutamine is an amino acid — one of the building blocks your body uses to make protein.

There are no other active ingredients listed, and no inactive fillers or binders are included in this product.

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 athletic performance.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Sports endurance, Muscle repair, Training 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 Exercise-induced muscle damage.

The evidence shows glutamine is effective for sickle cell disease. For HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma, glutamine is possibly effective — meaning there's some supportive evidence, but it's not yet conclusive.

We hold no effectiveness data for other 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 in healthy adults when taken by mouth. The most common side effects are gastrointestinal (bloating, belching, flatulence, nausea, vomiting, diarrhea, constipation, and abdominal pain), along with headache and musculoskeletal pain.

Dizziness and headache have also been reported; in one case, dizziness improved when the dose was lowered. People with kidney or liver disease should only use this product under medical supervision.

During pregnancy, glutamine is rated likely safe. However, there isn't enough safety data to know whether it's safe at supplement doses while breastfeeding — talk with your doctor or pharmacist before using it in that situation.

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 anticonvulsants (seizure medications), check with your doctor or pharmacist before starting this product — glutamine may theoretically reduce how well these drugs work. No other medication interactions are documented in our data for the ingredients we could check.

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.

Gluta-Lyn 1500 is a single-ingredient glutamine powder that's well tolerated in healthy people and has solid evidence for sickle cell disease and some support for muscle recovery and HIV-related wasting. If you take anticonvulsants or have kidney or liver disease, check with your doctor or pharmacist first.

Pregnancy appears okay, but breastfeeding safety isn't established — discuss it with your own healthcare provider.
