When to Choose NOW Sports Whey Protein Isolate
Value seekers who want the most protein per dollar with Informed Sport certification
NOW Sports delivers the best value in this comparison at $0.89/serving for 81 servings. The unflavored single-ingredient isolate is as pure as it gets. Informed Sport certification adds credibility. The trade-off is taste and aesthetics — this is no-frills protein at its most practical.
Strengths
- Best protein-per-dollar value — 81 servings at $0.89/serving
- Single-ingredient unflavored option for maximum purity
- Informed Sport certified with GMP-compliant manufacturing
Limitations
- Unflavored version has a bland dairy taste — best mixed into smoothies
- Lower protein per serving (25g) in unflavored compared to some competitors
- Basic packaging and branding lacks the premium feel of boutique brands

- Clean ingredient list with no artificial sweeteners, colors, or fillers
- Customizable flavor system with separate stick packs for flavor variety
Limitations
