Analysis

A 25 g plant-protein serving and detailed amino-acid profile provide meaningful nutritional depth, including useful iron and vitamin C. The label provides enough detail to understand the central formula and serving.

Many greens, enzymes, probiotics, and other extras lack usable amounts, making the crowded formula difficult to assess and relatively expensive. That trade-off materially affects potency, convenience, transparency, or value.

Best suited to people wanting a broad meal-style plant protein rather than a focused amino-acid supplement. Expectations should match the disclosed ingredients and the product's focused role.

Who is it for
  • people wanting a broad meal-style plant protein rather than a focused amino-acid supplement
  • People who prefer the disclosed format and serving style
  • Users whose priorities match the formula rather than broader nutrition
Best for
  • Provides a substantial protein serving
  • Discloses a detailed amino-acid profile
  • people wanting a broad meal-style plant protein rather than a focused amino-acid supplement

Pros

  • Provides a substantial protein serving
  • Discloses a detailed amino-acid profile
  • Includes useful iron and antioxidant vitamins

Cons

  • Many specialty additions have no assessable amount
  • High serving cost for a protein powder
  • Protein-bound amino acids are poor for precise targeted dosing

Warnings

  • Contains 1,508 mg 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 meal powder.

Nutrient quality

68 High impact

Plant proteins provide a complete amino acid profile, but protein-bound forms require digestion and most added ingredients have no usable amounts. The protein and many amino acid amounts are substantial, though some targeted actives remain below preferred standalone ranges.

.

Ingredient transparency

63 Moderate impact

Many core amino acids have stated amounts, but numerous secondary ingredients lack usable doses. Serving count is supplied, while full directions and the other-ingredients list are missing.

.

Customer satisfaction

53 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

32 Situational impact

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

Substantial protein plus useful iron and lysine can support hair when dietary intake is inadequate. The formula is nutritional rather than a targeted hair-growth intervention.

Core amounts are clear, but the extensive zero-quantity ingredient list is not assessable. Broad superfood and digestive additions sharply reduce focus.

Arginine is supplied at a strong amount that may support nitric-oxide production and blood flow. Protein and food-based ingredients add general nutrition but do not create a comprehensive cardiovascular formula.

The exact amount is clear, although the label does not confirm the L-isomer and beet or pomegranate amounts are unavailable. The product offers useful vasodilation depth but limited lipid, rhythm, or cardiac-energy coverage.

Methionine · 530 mg

A substantial protein serving supplies methionine, cystine, lysine, and other amino acids used to build keratin. The formula is a meal-style powder rather than a focused nail product, and many botanical additions have no disclosed amounts.

Methionine and total protein are meaningfully quantified, supporting real structural contribution. The large collection of zero-quantity extras creates poor transparency and heavy label padding.

Vitamin D · mcgIron · 8.5 mgPotassium · 80 mg

Protein, branched-chain amino acids, arginine, and whole-food nutrients provide metabolic fuel for meals and activity. The substantial protein-bound amino acids support nutrition more than an immediate energy effect.

Key amino acids require digestion and several amounts are below focused supplemental ranges. A very broad meal powder disperses its effects across nutrition rather than targeted mitochondrial, alertness, or adaptogen pathways.

Report overview
Methionine · 530 mg OverallScore67
D Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

Generic methionine is listed without confirming the natural L-isomer or a purity grade. The exact 530 mg amount provides high potency within the protein formula. Very high serving cost is partly tied to the broader meal-style ingredients rather than the methionine dose alone.

Alanine · 1406 mg OverallScore67
D- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD+ Value

The reported alanine amount is substantial within the protein blend. The label does not name the L-isomer, and whole-protein digestion is required before uptake. Neutral value is appropriate because alanine is secondary to the broader formula.

Proline · 1259 mg OverallScore66
D Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

A substantial proline amount is disclosed within a rice-and-pea protein matrix. The powder reaches a high dose but does not provide the purity of isolated L-proline. Relatively high cost per target amount limits its appeal for proline-specific use.
