Nutrient quality

70 High impact

High-purity isolate ensures excellent protein delivery with zero fats or sugars. Mineral levels are only sufficient for maintenance and do not support concentrated heart health targets.

Ingredient transparency

98 Highest impact

Labeling is fully transparent and accurately reflects both protein and incidental mineral content. Clearly defined ingredient naming supports a high degree of consumer trust.

Customer satisfaction

86 Highest impact

Massive review volume and a strong average rating confirm user satisfaction with the product's purity. Users find the isolate very easy to tolerate and effective for muscle support.

Value for money

90 Highest impact

At $1.75 per serving, the product offers competitive value for a high-transparency isolate in a 2lb tub. For heart health, the value is diluted as it does not replace concentrated mineral products.
