Analysis

The disclosed BCAA amounts are the main benefit, led by 3.5 g of leucine and supported by 1.75 g each of isoleucine and valine. A 2.5 g glutamine serving broadens the amino-acid support without turning the blend into a high-dose glutamine product.

Sodium and potassium can help replace some minerals during ordinary workouts, though the amounts are not aimed at heavy electrolyte losses. The listed citrulline malate, carnitine, CLA, and cayenne create a wider performance and weight-management theme, but their modest quantities make them supporting ingredients.

Clear amounts for most active ingredients help users understand what each scoop provides. Missing inactive-ingredient details and limited source or processing information make it harder to judge flavoring, sweeteners, mixability, and the quality of several components.

Who is it for
  • People looking for a BCAA drink around exercise
  • Active adults who need modest sodium and potassium
  • Users comfortable with a multi-ingredient flavored powder
Best for
  • Supporting amino-acid intake around workouts
  • Routine sessions with light mineral replacement
  • Users who value disclosed BCAA amounts

Pros

  • Supplies a balanced and clearly stated BCAA serving
  • Leucine is present at a useful per-serving level
  • Includes moderate glutamine for broader workout support
  • Provides slightly more potassium than the blueberry flavor

Cons

  • Citrulline is below the amount expected from a dedicated product
  • Carnitine and CLA contribute limited practical value at these amounts
  • Electrolytes may be insufficient for long or very sweaty sessions
  • The supplied data does not show inactive ingredients or detailed sourcing

Warnings

  • Capsimax cayenne extract can feel irritating to users with a sensitive stomach
  • The CLA source and protection from oxidation are not disclosed
  • Anyone restricting sodium should include the 230 mg serving amount in their daily total

Nutrient quality

70 High impact

The branched-chain amino acids reach useful workout amounts and glutamine is moderate. Several secondary actives are lightly dosed or incompletely characterized, and the formula poorly matches some listed goals.

.

Ingredient transparency

64 Moderate impact

Most amino-acid amounts are individually disclosed and easy to compare. Blank ingredient names, an aggregate electrolyte blend, missing CLA detail, and absent non-active ingredients leave notable gaps.

.

Customer satisfaction

67 High impact

Aggregate satisfaction data are moderately favorable and supported by substantial volume. Specific firsthand comments were not supplied, leaving repeated complaints and purpose fit uncertain.

.

Value for money

54 Moderate impact

Useful amino-acid amounts provide some practical value. Light secondary dosing and only moderate serving economics keep the formula from standing out.

C- Goal FitC+ Strength of SupportC CoverageB- Formula Quality
Potassium · 210 mg

Branched-chain amino acids, glutamine, and electrolytes support workout nutrition and hydration more than cellular energy. Citrulline malate is well below common performance amounts, and the formula contains no caffeine, creatine, or meaningful B-vitamin support.

Added carnitine, conjugated linoleic acid, and capsicum broaden the metabolic theme but remain modest for functional energy. The product may fit training recovery, but it is not a strong match for alertness or fatigue support.

Potassium · 210 mgL-Carnitine · 500 mgVitamin B6 · 640 mcg

Citrulline malate, carnitine, and potassium provide some relevance to blood flow, cardiac energy, and electrolyte balance. The sports-recovery formula is designed around amino acids rather than cardiovascular support.

Citrulline and carnitine are both below fuller targeted amounts, and the potassium contribution is modest. Most of the serving consists of branched-chain amino acids that do not deepen the cardiovascular pathways.

Report overview
Sodium · 230 mg OverallScore80
B Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB+ Value

Standard sodium salts provide functional electrolyte support without a premium natural source. The sodium dose can support lighter or more individualized hydration needs. Well-chosen supporting electrolytes strengthen the mineral profile, while the serving cost remains reasonable for the broader formula.

Valine · 1750 mg OverallScore78
B- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

Free-form L-valine supplies the full 1750 mg benchmark in a practical workout powder. The label states the individual dose, though it does not mention micronization or external sport testing. The flavored multi-ingredient formula has fair cost efficiency per gram of valine.

Isoleucine · 1750 mg OverallScore74
B+ Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyD+ Value

A fully disclosed serving supplies 1,750 mg of isolated L-isoleucine, matching the collection benchmark. The scoopable powder should be practical for mixing, although no micronization, source method, or independent testing is stated. The serving cost provides only moderate value for the disclosed dose.
