When to Choose Klean Athlete Klean Isolate

Professional and Olympic athletes who need NSF-certified protein with pharmaceutical-grade purity

Klean Athlete is purpose-built for competitive athletes who cannot risk contamination. NSF Certified for Sport plus pharmaceutical-grade manufacturing standards make it one of the safest protein powders available. The unflavored single-ingredient option is ideal for purists.

Strengths

  • NSF Certified for Sport — trusted by Olympic and professional athletes
  • Single-ingredient unflavored option available for maximum purity
  • Made by supplement industry leader (Atrium Innovations) with pharmaceutical-grade standards

Limitations

  • Flavored options (Vanilla, Chocolate, Strawberry) are less sweet than mainstream competitors
  • Only 20 servings per pouch at $2.20/serving is expensive
  • Limited retail availability — primarily sold through specialty channels

When to Choose Orgain Organic Plant-Based Protein Powder

Budget-conscious organic shoppers (note: Consumer Reports heavy metal flag)

Orgain offers affordable USDA Organic plant protein with good taste, but Consumer Reports found lead at 143% over CA Prop 65 limits. The organic certification and pleasant flavor make it appealing, but the heavy metal data is a significant concern that health-conscious buyers should weigh carefully.

Strengths

  • USDA Organic and Non-GMO Project Verified with 21g plant-based protein
  • Good taste consistently praised in user reviews for a plant-based powder
  • Affordable at $1.80/serving compared to premium plant-based competitors

Limitations

  • Consumer Reports found 0.72μg lead/serving — 143% over CA Prop 65 limit
  • Uses organic erythritol and stevia which some find has an aftertaste
  • No NSF or Informed Sport certification for banned substance testing
