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.

Limitations
- Flavored options (Vanilla, Chocolate, Strawberry) are less sweet than mainstream competitors

- Limited retail availability — primarily sold through specialty channels
When to Choose Raw Grass Fed Whey Protein
Purity-focused buyers who want single-ingredient whey with published heavy metal COAs
Raw Organic Whey differentiates through published batch-level COAs that verify heavy metal and contaminant levels. The single-ingredient cold-processed formula is as clean as protein gets. No major certification but the transparent lab testing provides strong safety assurance.
Strengths
- Single-ingredient 100% grass-fed whey with published third-party COAs for heavy metals
- Cold-processed and undenatured to preserve natural protein structures
- Published batch-level certificates of analysis for heavy metals and contaminants
Limitations
- No NSF or Informed Sport certification — relies on published COAs instead
- Unflavored with a mild grass-fed dairy taste — not for flavor seekers
- Basic packaging and smaller brand with limited retail presence
