Analysis

The isolate delivers 20 g of protein with almost no fat and no carbohydrate. Soy is a complete plant protein, making the powder useful for meals and training.

Calcium is a notable addition, while sodium remains modest for a protein powder. Iron is present in a moderate amount without dominating the formula.

The unflavored format and larger supply offer strong versatility and value. A complete ingredient statement would improve confidence about processing aids and other inactive ingredients.

Who is it for
  • Plant-based adults who tolerate soy
  • Users seeking low-carbohydrate protein
  • People wanting an unflavored powder
Best for
  • Post-training protein
  • Meal supplementation
  • Low-carbohydrate shakes

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

93 Highest impact

Complete plant protein and a low relative serving cost provide strong value without formula inflation. The larger supply is highly competitive for a plain isolate.

Report overview
Sodium · 170 mg OverallScore64
D Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyA+ Value

Its 170 mg sodium amount is too low for dependable replacement during intense exercise. The sodium source and supporting mineral forms are not fully identified, and no buffering mineral is shown. The economical, carbohydrate-free serving is transparent, but its sodium amount is too low for demanding exercise.

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.
