HelloPharmacist Scorecard of Hit BCAA 4:1:1 + Glutamine Strawberry by DY Nutrition

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

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 5 of its 6 active ingredients.
  • “Branched-Chain Amino Acids” is listed as a grouped ingredient — the label gives one combined amount (7,500 mg) without saying how much of each component you get.
  • “Fat” is listed as a grouped ingredient — the label gives one combined amount (0.20 Gram(s)) without saying how much of each component you get.

This powder contains seven active ingredients centered on branched-chain amino acids (BCAAs)—L-leucine, L-isoleucine, and L-valine in a 4:1:1 ratio—plus L-glutamine monohydrate, salt, fat, and fibers. The BCAAs are amino acids your muscles can use directly during and after exercise; L-glutamine is another amino acid that supports immune function and gut health.

You'll also see inactive ingredients listed: additional branched-chain amino acids in the blend itself, plus acid, sweetener, flavoring, emulsifier, and color to make the powder taste and mix well.

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, Critical illness (trauma), Wound healing, Burns — and 3 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 in this product is rated Effective for sickle cell disease and Possibly Effective for HIV/AIDS-related wasting, postoperative (after-surgery) recovery, and critical illness from trauma. The effectiveness data we hold doesn't cover the other amino acids in the BCAA blend or their use for general athletic performance; evidence for those claims isn't established in our current monographs.

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 generally well tolerated in healthy adults. The most common side effects from oral glutamine are digestive: belching, bloating, constipation, diarrhea, flatulence, nausea, and vomiting, especially at higher doses (10–30 grams daily).

Headache, dizziness, and musculoskeletal pain have also been reported. Rare cases of mania or hypomania were noted in people with bipolar disorder.

If you have kidney or liver disease, you should take glutamine only under medical supervision. There isn't enough safety data to recommend it in supplement doses during pregnancy; the data does support it as likely safe during pregnancy overall, but talk to your doctor about your specific situation.

During breastfeeding, avoid supplement doses unless your clinician advises otherwise, because reliable safety information is limited.

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 use—L-glutamine may theoretically antagonize their effects. The other amino acids in the blend were not checked against medication databases.

The bottom line

Scorecard at a glancePartially disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
