Analysis

The powder provides 20 g of protein with a detailed amino-acid breakdown, including meaningful amounts of glycine, glutamic acid, tyrosine, lysine, and branched-chain amino acids. One gram of leucine is modest for a protein serving, so it may be less suited to users who want a strong leucine trigger from each scoop.

A whole seed-protein matrix supports broad protein intake but does not work like isolated free-form amino acids. Competition among amino acids also limits the product's precision for goals tied specifically to tyrosine or phenylalanine, while the 6 g fat and 11 g carbohydrate content make it less protein-dense than leaner powders.

The extensive profile disclosure is a genuine strength, but the supplied details do not identify the specific seed sources, processing methods, flavoring ingredients, or other additives. It fits best as a flavored general-purpose protein rather than as a substitute for a precisely dosed amino-acid product.

Who is it for
  • Adults seeking a plant-based protein powder
  • People who want a disclosed amino-acid profile
  • Users comfortable with moderate carbohydrate and fat per serving
Best for
  • General daily protein intake
  • Adding protein and calories to shakes
  • People who prefer a chocolate-flavored seed-protein format

Pros

  • Provides 20 g of protein per serving
  • Discloses individual amino-acid amounts
  • Contains only 1 g of sugar
  • Includes a broad spread of essential and nonessential amino acids
  • Cholesterol-free according to the supplied label

Cons

  • Leucine amount is modest for a 20 g protein serving
  • Whole-protein amino acids are not ideal for targeted supplementation
  • Specific seed sources and processing details are not provided
  • Carbohydrate and fat reduce protein density
  • Value is weak for users interested in only one amino acid

Warnings

  • The serving contains 443 mg of phenylalanine, so people with phenylketonuria need to avoid or strictly manage it.
  • The specific seed sources are not listed in the supplied details, which matters for anyone with seed allergies.

Nutrient quality

82 Highest impact

A complete amino-acid profile provides broad nutritional support, though all amino acids remain protein-bound rather than isolated. The total protein amount is meaningful, while leucine and several target amino acids are modest for specialized use.

.

Ingredient transparency

79 High impact

Total protein and a detailed amino-acid profile make the nutritional contribution easy to assess. The protein sources, intake directions, flavor system, sweeteners, and other inactive ingredients are not shown in the supplied data.

.

Customer satisfaction

59 Moderate impact

The average rating is positive, but the moderate feedback pool provides limited confidence. No specific experience details are supplied to assess repeated concerns about taste, texture, or use.

.

Value for money

54 Moderate impact

The complete protein serving and detailed amino-acid profile provide real nutritional value. High serving cost and modest leucine depth make it less competitive than many plant-protein powders.

A complete seed-protein serving supplies substantial amino acids needed to build keratin. Lysine, cystine, methionine, glycine, and other amino acids are all clearly quantified.

Protein support is most useful when dietary intake is inadequate and does not address micronutrient or hormonal causes of shedding. The focused food-based formula provides strong structural depth without label padding.

A substantial protein serving supports muscle maintenance, and the disclosed glycine contributes building blocks for collagen and glutathione. The detailed amino acid profile makes the nutritional contribution unusually transparent.

Glycine is part of a seed-protein matrix and does not reach the usual targeted amount for isolated use. The powder therefore fits general protein support better than a precise healthy-aging supplement.

The seed-protein blend supplies 2360 mg of glycine, which may support immune modulation and tissue repair. Glycine is embedded in a complete protein matrix rather than supplied as isolated free-form glycine.

The substantial food serving provides amino acids but no direct inflammatory-enzyme inhibitor or standardized botanical. Its anti-inflammatory relevance is secondary to the product’s main role as a protein powder.

The seed protein provides tyrosine, tryptophan, phenylalanine, and histidine that participate in neurotransmitter and neural-support pathways. As a complete protein, it is not a targeted cognitive supplement.

Several amino acids reach relevant label amounts, but they compete with many other amino acids for brain transport. The whole-protein format therefore limits focused cognitive delivery despite transparent profiling.

The seed-protein amino acid profile supplies glycine and tryptophan that can contribute to inhibitory signaling and serotonin production. Both amounts are relevant within a food-based protein serving.

Competing amino acids limit targeted tryptophan uptake, while glycine remains below the usual focused sleep amount. The bulky protein powder is therefore a weak substitute for a dedicated calming or sleep-support formula.

The seed protein supplies substantial glycine and a moderate tryptophan amount, giving it limited sleep relevance. Its primary role remains nutrition, and the full protein matrix competes with tryptophan for brain uptake.

Glycine approaches but does not reach the gram-level target commonly studied before bed. A bulky protein serving with many amino acids is less precise than isolated glycine or tryptophan for sleep support.

Glycine and glutamic acid provide substantial amino acid substrates that may support conjugation and glutathione synthesis. The seed protein does not include concentrated liver botanicals, NAC, or targeted metabolic cofactors.

The amounts are meaningful, but the amino acids remain protein-bound and are not optimized for precise dosing. It has indirect detox relevance as a protein food rather than as a dedicated clearance formula.

Report overview
Alanine · 720 mg OverallScore67
D- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD+ Value

The reported alanine amount is substantial within the seed-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 · 960 mg OverallScore66
D Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

A high proline amount is clearly disclosed within a seed-protein amino acid profile. The format is easy to mix but lacks the purity and precision of isolated L-proline. Relatively high cost per target amount limits its fit for focused supplementation.

Glutamic Acid · 2660 mg OverallScore60
D+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyF Value

The seed protein supplies a substantial naturally occurring glutamic acid amount within a detailed amino acid profile. The label does not specify the L-isomer, and the amino acid remains protein bound rather than free form. High serving cost is partly balanced by a complete protein serving and broad amino acid content.
