Analysis

The formula is centered on a substantial branched-chain amino-acid blend, with 5,000 mg leucine and 2,500 mg each of isoleucine and valine. Those clearly disclosed amounts fit workout-focused muscle support better than general energy or daily wellness.

Glutamine is present at 2,000 mg, while 1,000 mg of citrulline malate is modest for a performance formula. Beet and coconut water concentrate add breadth, but the probiotic is listed only by weight rather than a viable-organism count, making its practical contribution difficult to judge.

Nearly one gram of vitamin C and 2,388 mg of malic acid create a strongly acidified drink that may be hard on the stomach or teeth. With only 15 servings and several secondary ingredients below more useful workout amounts, the powder is less compelling for users seeking either simple BCAAs or broad wellness support.

Who is it for
  • Resistance-training users who want a high-dose BCAA powder
  • People who prefer individually disclosed amino-acid amounts
  • Users who tolerate acidic flavored drink mixes well
Best for
  • Workout-focused BCAA support
  • High leucine, isoleucine, and valine intake
  • Combining BCAAs with vitamin C

Pros

  • Supplies 5,000 mg of leucine
  • Provides 2,500 mg each of isoleucine and valine
  • Discloses separate amounts for the main amino acids
  • Includes a substantial 996 mg vitamin C amount

Cons

  • Glutamine and citrulline are modest relative to the headline BCAAs
  • Probiotic content is listed by weight without a viable-organism count
  • Source, micronization, and sport-testing details are not provided
  • Only 15 servings weakens practical value

Warnings

  • The 996 mg vitamin C amount may cause loose stools, nausea, or abdominal discomfort in sensitive users.
  • The combination of vitamin C and 2,388 mg of malic acid may aggravate reflux or stomach irritation.
  • Frequent sipping of the strongly acidic drink may increase enamel sensitivity; diluting it and rinsing the mouth with water can reduce prolonged acid contact.

Nutrient quality

80 Highest impact

The branched-chain amino acids are supplied in substantial free-form amounts that fit exercise use. Conventional forms, an oversized leucine amount, and a probiotic listed without a viable-organism count reduce confidence in the finer details.

Ingredient transparency

80 Highest impact

Individual amounts are disclosed and no proprietary blend obscures the main amino-acid formula. The probiotic lacks a viable-organism count, and the supplied details omit complete usage and inactive-ingredient information.

Customer satisfaction

73 High impact

The strong average rating and moderate review volume support a favorable broad impression. No review excerpts identify taste, mixability, tolerance, or repeated complaints, leaving experience-specific conclusions unsupported.

Value for money

68 High impact

Substantial amino-acid doses give each serving real workout utility. A short supply and premium serving cost limit competitiveness despite the focused formula.

C Goal FitB+ Strength of SupportD+ CoverageA Formula Quality

Clearly disclosed branched-chain amino acids provide muscle-focused fuel and recovery support around exercise. The formula does not address cellular-energy cofactors, alertness, or stress resilience in a broad way.

Isoleucine and valine reach strong amounts, while source and sport-testing details are not provided. Its focused powder design is more relevant to training nutrition than to everyday fatigue.

Vitamin C · 996 mg

A large vitamin C amount provides direct antioxidant and immune-cell support, and glutamine may support intestinal-barrier metabolism. The rest of the formula is designed for workout recovery and hydration rather than broad immune function.

Vitamin C and amino-acid amounts are clearly disclosed, but the probiotic is listed by weight without a viable-organism count. High-dose vitamin C can cause digestive upset in sensitive users, especially alongside a strenuous workout formula.

Vitamin C · 996 mg

Nearly one gram of vitamin C provides a meaningful antioxidant and collagen-related nutrient dose. The amino-acid blend is primarily designed for exercise recovery rather than broad daily wellness.

Branched-chain amino acids are substantial, but the formula omits most foundational vitamins, minerals, and essential fats. The heavily acidified powder may aggravate reflux, stomach irritation, or enamel sensitivity in susceptible users.

Vitamin C · 996 mg

Nearly one gram of vitamin C can support collagen synthesis, but the BCAA drink is only tangentially related to skin. Vitamin C is supplied at a substantial 996 mg amount.

Skin support is confined largely to one collagen-synthesis cofactor. A deep vitamin C contribution cannot provide structural, barrier, or broad photoprotective coverage on its own.

Report overview
Valine · 2500 mg OverallScore78
B- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

Free-form L-valine is present at a strong dose and is individually disclosed. The standard powder supports practical mixing, though no micronization or sport certification is stated. Its richer formula raises the cost per gram of valine, making value only moderate.

Isoleucine · 2500 mg OverallScore68
B+ Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyF Value

The powder supplies a high 2,500 mg dose of isolated L-isoleucine with clear disclosure. No micronization, source detail, or independent sport testing is stated. Its serving cost is high despite the potent amino acid amount.

Leucine · 5000 mg OverallScore64
C Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyB+ Value

The formula discloses a substantial free-form L-leucine amount, but it exceeds the collection's defined trigger range. Its source and solubility processing are not identified, leaving ingredient quality and mixability less certain. Cost efficiency remains favorable, though the oversized and potentially multi-scoop serving reduces practicality.
