A complete essential-amino-acid profile is clearly itemized in a convenient one-capsule serving. Individual amounts are very small, making the formula inefficient for focused leucine, lysine, phenylalanine, histidine, or BCAA use.

Analysis

A complete essential-amino-acid profile is clearly itemized in a convenient one-capsule serving. The label provides enough detail to understand the central formula and serving.

Individual amounts are very small, making the formula inefficient for focused leucine, lysine, phenylalanine, histidine, or BCAA use. That trade-off materially affects potency, convenience, transparency, or value.

Best suited to people wanting a broad low-amount amino-acid top-up rather than targeted supplementation. Expectations should match the disclosed ingredients and the product's focused role.

Who is it for
  • people wanting a broad low-amount amino-acid top-up rather than targeted supplementation
  • People who prefer the disclosed format and serving style
  • Users whose priorities match the formula rather than broader nutrition
Best for
  • Lists nine essential amino acids separately
  • Uses recognizable L-form amino acids
  • people wanting a broad low-amount amino-acid top-up rather than targeted supplementation

Pros

  • Lists nine essential amino acids separately
  • Uses recognizable L-form amino acids
  • One-capsule serving is convenient

Cons

  • Individual amino-acid amounts are very low
  • High cost per gram for targeted ingredients
  • Capsule is poorly suited to meaningful sports dosing

Warnings

  • Contains phenylalanine and is not suitable for people with phenylketonuria.
  • The supplied label details do not show a PKU warning despite the phenylalanine content.
  • People who must restrict phenylalanine should avoid this formula.

Nutrient quality

70 High impact

The essential amino acids are clearly identified as L-isomers or stable hydrochloride forms. All individual amounts are far below focused amino acid doses at the listed serving.

.

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

61 Moderate 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

43 Lower impact

Weak dosing or poor focus makes the serving difficult to justify. Comparable products offer better targeted dose value.

Report overview
Methionine · 70 mg OverallScore66
A- Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyD- Value

L-methionine is precisely identified within a clearly dosed essential-amino-acid formula. The 70 mg amount is individually stated but remains in the low range for targeted structural support. Low serving cost is attractive, although methionine-specific potency is modest.

View ingredientView products
Isoleucine · 79 mg OverallScore63
B- Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyA+ Value

Isolated L-isoleucine avoids protein digestion, but capsule delivery slows release compared with a dissolved powder. The 79 mg amount is far too small for meaningful exercise-fuel support by itself. Low serving cost and exact dose disclosure are positives, although sourcing and independent sport testing are not documented.

View ingredientView products
Phenylalanine · 115 mg OverallScore46
C+ Active Ingredient Quality & BioavailabilityD- Dose, Safety & Label TransparencyF Value

L-phenylalanine is clearly named, but the 115 mg amount remains well below a targeted mood or focus dose. A full essential-amino-acid profile adds competition from leucine, isoleucine, and valine, reducing its suitability for brain uptake. Cost per active amount is very high, and the supplied label details do not include a PKU warning.

83 Performance

Branched-Chain Amino Acids

Lake Avenue Nutrition
Clear L-form branched-chain amino acids provide substantially larger amounts than the original low-dose essential blend. The formula is narrower, yet it has stronger practical dosing for its stated ingredients.
82 Performance

Branched-Chain Amino Acids

NOW Sports
The focused serving supplies 1,600 mg leucine and 650 mg each of isoleucine and valine. Other essential amino acids are absent, but the disclosed branched-chain amounts are much more meaningful.
79 Performance

Branched Chain Amino Acids (Free Form)

Life Extension
Free-form amino acids provide a simple and readily available branched-chain profile at larger amounts. The serving remains modest and loses the original lysine, methionine, phenylalanine, histidine, threonine, and tryptophan.
60 Budget

Daily Amino Acid

21st Century
A very low serving cost preserves a broad amino-acid list in a simple tablet. Its trace doses and DL-methionine are weak points, so the lower cost comes with even less active utility.
84 Budget

BCAA 3200 mg

Best Naturals
A lower serving cost provides useful branched-chain amino amounts with clear L-form disclosure. It drops the other essential amino acids, but delivers far more leucine, isoleucine, and valine.
80 Budget

Mega-Size BCAA 1000 Caps

Optimum Nutrition
The low-cost capsule serving supplies more branched-chain amino material than the original. Total dosing remains modest and essential amino coverage is narrower, but recurring cost is lower.
77 Value

Amino Complex Berry Flavored

Thorne
A clearly disclosed essential-amino profile supplies much larger amounts, including 1,250 mg leucine and 650 mg lysine. It is costly and several secondary amino acids remain light, but breadth and dose utility are stronger than the original.
68 Value

BCAA Plus Branched Chain Amino Acids

Solgar
The branched-chain amino amounts are larger and clearly stated, while vitamin B6 adds a defined supporting nutrient. The overall amino dose remains low and the high B6 amount weakens long-term value.
79 Value

Amino-9 Essentials Powder

NOW Sports
Nine essential amino acids are individually disclosed at much larger amounts than the original capsule serving. Some remain below standalone target amounts, but breadth and dose utility create a stronger value balance.
