HelloPharmacist Scorecard of Universal BCAA Stack Grape Splash 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.

Universal BCAA Stack Grape Splash contains 4 active ingredients: glutamine, leucine, isoleucine, and valine. Glutamine is an amino acid your body uses for muscle recovery and immune function.

The other three—leucine, isoleucine, and valine—are branched-chain amino acids (BCAAs) that support muscle protein synthesis and are often used around workouts. The product also contains inactive ingredients including natural grape flavor, citric acid, aspartame, and food colorings.

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 support.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Wound healing.
  • 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 is rated effective for sickle cell disease and possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma. We don't have effectiveness ratings on file for leucine, isoleucine, or valine 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.

Glutamine is generally well tolerated in healthy adults. The most common side effects from oral glutamine are gastrointestinal—belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting—especially at higher doses.

Headache and musculoskeletal pain have also been reported. People with kidney or liver disease should only use glutamine under medical supervision.

There isn't enough safety data to recommend supplemental glutamine while breastfeeding unless your doctor advises it; pregnancy data rates it as likely safe. In rare cases, glutamine has been linked to dizziness and, in people with bipolar disorder, to mood changes—though these are uncommon.

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 pharmacist before starting—glutamine may theoretically reduce how well they work. We couldn't check the other three amino acids in this product for interactions, so run your full medication list through the checker below.

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 BCAA product is worth considering if you're focused on muscle recovery and don't take anticonvulsants. If you take seizure medications, blood pressure drugs, or any other prescription medication, check your specific drugs with the tool on this page before you buy.

Talk to your pharmacist or doctor if you have kidney or liver disease, or if you're pregnant or breastfeeding.
