HelloPharmacist Scorecard of ABC White Grape by Core Nutritionals

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 6 of its 6 active ingredients.
  • “Branched-Chain Amino Acids” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

ABC White Grape is a powder with six active ingredients designed to support athletic performance and recovery. L-glutamine supports muscle recovery and may help with sickle cell disease and critical illness.

The three branched-chain amino acids—L-leucine, L-isoleucine, and L-valine—work together to fuel muscles during and after exercise. CarnoSyn (a branded form of beta-alanine) may boost physical performance, and citrulline malate helps with blood flow and endurance.

The inactive ingredients are natural and artificial flavors, citric acid, and the sweeteners sucralose and acesulfame-K.

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 performance, endurance, and recovery.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle breakdown, Exercise-induced muscle damage, Physical performance, Postoperative recovery, Sarcopenia — and 3 related terms.
  • The strongest evidence on file: Glutamine is rated "Possibly Effective" for Postoperative recovery (Natural Medicines).
  • Also on file: Beta-alanine is rated "Possibly Effective" for Athletic performance, Physical performance.
  • Also on file: Glutamine is rated "Possibly Ineffective" for Athletic performance.

L-glutamine is effective for sickle cell disease and shows possible effectiveness for HIV/AIDS-related wasting, postoperative recovery, and critical illness from trauma. CarnoSyn (beta-alanine) is possibly effective for athletic performance and physical performance; the evidence for its use in age-related cognitive decline, COPD, cognitive function, and menopausal symptoms is currently insufficient to rate.

We don't have effectiveness data on file for the branched-chain amino acids, citrulline malate, or L-leucine individually.

The evidence, ingredient by ingredient Glutamine Beta-alanine

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-glutamine is generally well tolerated in healthy adults. The most common side effects are digestive—belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting—plus headache and musculoskeletal pain.

Dizziness has been reported. If you have kidney or liver disease, use it only under medical supervision.

Avoid supplemental doses during pregnancy and breastfeeding unless your doctor advises otherwise. Beta-alanine (CarnoSyn) is generally well tolerated but causes a harmless tingling feeling (paresthesia) and skin flushing in most people, typically starting on the scalp within 20 minutes and lasting about an hour.

Avoid beta-alanine during pregnancy and breastfeeding due to insufficient safety data. Long-term safety at high doses hasn't been studied.

Side effects, ingredient by ingredient Glutamine Beta-alanine

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 2 matched ingredients 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.

The main one to watch: if you take anticonvulsant medication (seizure drugs), check with your pharmacist before starting. The interaction is Moderate—L-glutamine might reduce how well your medication works—and though it hasn't been seen in patients yet, it's worth confirming your specific drug is safe.

Anticonvulsants

Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.

ABC White Grape by Core Nutritionals: Common Questions

Does ABC White Grape by Core Nutritionals interact with any medications?
Yes. Based on its ingredients, ABC White Grape has a known interaction with 50 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
ABC White Grape contains 6 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this help me build muscle?
This product is designed for athletic performance and recovery—the branched-chain amino acids and beta-alanine have research support for that purpose. L-glutamine is effective for muscle recovery in sickle cell disease and may help after surgery or critical illness, though the evidence for general athletic muscle-building is listed as possibly effective.
What's that tingling I feel?
That's the beta-alanine (CarnoSyn). It causes a harmless pins-and-needles feeling and skin flushing that usually starts on your scalp within 20 minutes and lasts about an hour. It's totally normal and not dangerous—just a dose-dependent sensation. If it bothers you, your body adapts with time, and it's milder at lower doses.
Can I take this while pregnant?
L-glutamine is rated likely safe in pregnancy. Beta-alanine doesn't have enough safety information, so it's best to avoid it unless your doctor says otherwise. Talk with your pharmacist or doctor about whether this powder is right for you during pregnancy.
Can I take this while breastfeeding?
L-glutamine doesn't have enough reliable safety data during breastfeeding, so avoid supplemental doses unless your doctor recommends them. Beta-alanine also doesn't have enough safety information for breastfeeding. Check with your pharmacist or doctor before using this product.
What if I have kidney or liver problems?
L-glutamine should only be used under medical supervision if you have kidney or liver disease. Talk with your doctor or pharmacist before starting this product.
What does each ingredient do?
L-glutamine supports muscle recovery and critical illness. The three branched-chain amino acids fuel muscles during exercise. Beta-alanine (CarnoSyn) boosts athletic performance. Citrulline malate improves blood flow and endurance. Together they're meant to enhance workout performance and aid recovery.
