HelloPharmacist Scorecard of BCAA Stack Lemon Lime by Universal

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

This powder contains 4 active ingredients: glutamine, leucine, isoleucine, and valine. Glutamine is an amino acid your body uses for immune function and gut health; the other three (leucine, isoleucine, and valine) are branched-chain amino acids often used by people doing strength training to support muscle recovery.

The powder also contains inactive ingredients including citric acid for flavor, aspartame as a sweetener, and food dyes (Yellow #5 and FD&C Blue #1).

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 anti-catabolic support during training.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Wound healing, muscle protein synthesis, lean mass preservation — and 1 related terms.
  • 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.

Glutamine has strong evidence for treating sickle cell disease. It's rated possibly effective for HIV/AIDS-related muscle wasting, recovery after surgery, and critical illness from trauma.

We don't have effectiveness ratings on file for leucine, isoleucine, or valine in this product—the evidence for branched-chain amino acids in muscle recovery is established in general nutrition science, but the specific ratings aren't in our data for 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.

Glutamine is rated likely safe in pregnancy and lactation. In general, it's well tolerated, but gastrointestinal side effects—bloating, gas, nausea, constipation, or diarrhea—can happen, especially at higher doses.

A small number of people have reported dizziness or headache. If you have kidney or liver disease, use it only under your doctor's supervision.

Because safety data is limited, don't take supplemental glutamine while breastfeeding unless your clinician recommends 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), double-check this product with your pharmacist before you start—glutamine may theoretically work against how they function. For leucine, isoleucine, and valine, we hold no interaction data, so those three cannot be checked against your medications.

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 is a straightforward branched-chain amino acid supplement often used by people in training. If you take seizure medication, check with your doctor or pharmacist before starting—that's the main interaction to watch.

Otherwise, it's generally well tolerated, though some people notice bloating or digestive upset. Talk it over with your own doctor or pharmacist to make sure it fits your goals and health situation.
