HelloPharmacist Scorecard of Glutamine Select Wild Berry by Beverly International

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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Glutamine Select Wild Berry contains four active amino acids: L-glutamine, L-leucine, L-isoleucine, and L-valine. L-glutamine is the primary ingredient and plays a role in immune function, gut health, and muscle recovery.

The three branched-chain amino acids (leucine, isoleucine, and valine) support muscle protein synthesis and may help with recovery after intense activity or illness. The powder also contains natural berry flavors, gums for texture, and natural color.

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

L-glutamine is rated effective for sickle cell disease. It's rated possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma.

We hold no effectiveness data in our system for the other three amino acids in this product.

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 rated likely safe in pregnancy and lactation. In healthy adults, it's generally well tolerated, though gastrointestinal side effects are common — belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting have been reported in trials and real-world use.

Headache, dizziness, and musculoskeletal pain also occur. High doses (10–30 grams daily) used in sickle cell studies produced more GI distress.

People with kidney or liver disease should only use this supplement under medical supervision, and there isn't enough safety data to recommend it at supplemental doses without doctor guidance.

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), discuss this product with your pharmacist before starting — L-glutamine may theoretically reduce their effectiveness, though this hasn't been proven in humans. No other documented interactions were found 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.

This product may help with sickle cell disease, HIV/AIDS wasting, or recovery after surgery or critical illness if your doctor recommends it. If you take seizure medication, check with your pharmacist first — the main ingredient may theoretically interfere.

GI upset is common, so start with a smaller dose if you're new to glutamine. Talk to your pharmacist about whether it's right for your situation.
