Making Your Decision
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 Naked Whey 100% Grass-Fed Whey Protein
Minimalists who want single-ingredient grass-fed whey with zero additives
Naked Whey is the ultimate minimalist protein powder — one ingredient: grass-fed whey concentrate. Cold-processed and additive-free, it scores highest on ingredient purity. The lack of major third-party certification is the main drawback, though they do publish some lab testing.
Strengths
- True single-ingredient protein — literally just grass-fed whey concentrate
- Cold-processed to preserve natural whey proteins and bioactive compounds
- Excellent value at $1.25/serving with 76 servings in the 5lb bag
Limitations
- No major third-party certification (no NSF, Informed Sport, or Labdoor)
- Flavored versions add organic coconut sugar, increasing carbs slightly per serving
- Uses concentrate rather than isolate — slightly higher fat/carbs per serving
