Analysis

The powder supplies 20 g of complete plant protein with no carbohydrate and very little fat. It can support daily protein intake and training without adding much else to a shake.

Calcium contributes useful nutritional breadth, while sodium stays modest. The supplied information does not include a full ingredient panel or amino acid breakdown.

The unflavored format is versatile, though the smaller container has slightly weaker value than the larger version. It remains a strong choice when soy is acceptable.

  • Plant-based users wanting complete protein

Nutrient quality

90 Highest impact

A complete soy isolate and meaningful protein amount provide focused nutrition with no obvious padding or excess. Missing processing details prevent a fully confident form assessment.

.

Ingredient transparency

78 High impact

Nutrition amounts and the soy isolate source are clear without a hidden blend. Missing directions, non-active ingredients, processing details, and mineral compounds leave some gaps.

.

Customer satisfaction

70 High impact

The aggregate rating is favorable, but it provides no specific experience evidence. The large review count gives the aggregate signal a stable volume base, while no detailed feedback is supplied to assess taste, mixability, tolerance, or recurring complaints.

.

Value for money

90 Highest impact

Complete plant protein and a low relative serving cost provide strong value without formula inflation. The smaller package is competitive, though the larger version offers a modest economy advantage.

Report overview
Sodium · 170 mg OverallScore65
D Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyA+ Value

The label gives a sodium amount without naming its source, limiting purity assessment. 170 mg is below the target range for intense sweat replacement; supporting electrolytes are present, but their forms do not establish high bioavailability; no trace-mineral complex or buffering compound is disclosed. The disclosed carbohydrate or sugar load is low, and no artificial color is listed; the low serving cost provides strong value.

Iron · 3 mg OverallScore46
F Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyF Value
The iron compound is not disclosed, preventing a meaningful judgment of absorption or tolerance. No complete set of absorption and blood-cell cofactors is present at the required levels. The elemental dose is clearly disclosed but is too low for a targeted iron need. The serving is expensive relative to its iron contribution. The broader soy protein may still provide benefits beyond iron alone.
