Analysis

A balanced free-form BCAA serving provides 1,600 mg leucine with 650 mg each of isoleucine and valine. The label provides enough detail to understand the central formula and serving.

The moderate amounts remain below demanding sports targets, and the four-capsule format is slower and less mixable than powder. That trade-off materially affects potency, convenience, transparency, or value.

Best suited to shoppers prioritizing clear dosing and favorable value over maximum potency. Expectations should match the disclosed ingredients and the product's focused role.

Who is it for
  • shoppers prioritizing clear dosing and favorable value over maximum potency
  • People who prefer the disclosed format and serving style
  • Users whose priorities match the formula rather than broader nutrition
Best for
  • Clearly quantifies all three BCAAs
  • Leucine leads the balanced formula
  • shoppers prioritizing clear dosing and favorable value over maximum potency

Pros

  • Clearly quantifies all three BCAAs
  • Leucine leads the balanced formula
  • Favorable cost for the amount delivered

Cons

  • Leucine is below a strong standalone trigger
  • Valine and isoleucine are modest
  • Four capsules are less workout-friendly than powder

Nutrient quality

89 Highest impact

The three branched-chain amino acids are supplied as clearly identified L-isomers. The balanced serving is useful, but leucine remains below a strong muscle-protein trigger and the other two amounts are modest.

.

Ingredient transparency

83 Highest impact

Active ingredients have stated amounts and no proprietary blend hides a dose. Serving count is supplied, while full directions and the other-ingredients list are missing.

.

Customer satisfaction

69 High impact

The supplied aggregate rating is the only evidence of general satisfaction and its reliability depends on rating volume. No comment-level evidence is available to assess recurring complaints or confirm how experience matches the intended purpose.

.

Value for money

86 Highest impact

The active quality and serving utility support reasonable value. The product is reasonably competitive, though stronger values are available.

Report overview
Leucine · 1600 mg OverallScore70
D+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB+ Value

The 1,600 mg dose provides a meaningful amount of free-form L-leucine, though it sits below the usual standalone trigger range. Four capsules make the serving manageable, and the exact leucine amount is clearly disclosed. Cost efficiency is favorable for the amount delivered, while the unbranded source and lack of stated processing leave some quality details uncertain.

Isoleucine · 650 mg OverallScore69
B- Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyA+ Value

The isolated L-isoleucine is clearly disclosed, but the moderate amount may offer limited support compared with more concentrated options. Capsule delivery also slows access compared with a dissolved powder, and no sourcing or independent testing details are provided. The low cost per serving makes it a practical choice for shoppers who value affordability over potency and verification.

Valine · 650 mg OverallScore63
C+ Active Ingredient Quality & BioavailabilityB- Dose, Safety & Label TransparencyD- Value

Explicit free-form L-Valine provides a clearly identified, biologically relevant source. The 650 mg serving is well below the collection benchmark, so it offers a limited amount for demanding sports use. Capsule delivery and absent sport-specific certification further limit its fit, while cost per gram remains moderate.

The Original Strawberry Kiwi Splash

XTEND
Higher disclosed amounts of all three BCAAs give 3.5 g leucine, 1.75 g isoleucine, and 1.75 g valine, plus glutamine, citrulline malate, and electrolytes, providing stronger standalone coverage than the original. The expanded powder formula adds ingredients beyond the original three-amino-acid focus, which may be unnecessary for someone seeking only BCAAs.

NOW Sports
The formula provides 1.6 g leucine, 0.65 g isoleucine, and 0.65 g valine in a focused alternative, although the supplied data do not establish a clear across-the-board upgrade over the original. Leucine still sits below a strong standalone muscle-protein trigger, and full directions and excipient details are not supplied.

Branched Chain Amino Acids (Free Form)

Life Extension
The formula provides 1.2 g leucine, 0.6 g isoleucine, and 0.6 g valine in a focused alternative, although the supplied data do not establish a clear across-the-board upgrade over the original. The serving remains modest for standalone use, and full directions and excipient details are not supplied.

Daily Amino Acid

Optimum Nutrition
The lower listed serving cost provides 0.5 g leucine, 0.25 g isoleucine, and 0.25 g valine, making it a more economical choice than the original. All three BCAA amounts are well below meaningful standalone levels, so the apparent serving value overstates practical coverage.
