Buying Guide

• What “100% pure” means: Look for products with a single ingredient or minimal additives. Undenatured or grass-fed options emphasize purity and protein quality.
• Protein type considerations: Whey concentrate vs. isolate. Isolates typically offer higher protein per serving and lower lactose; concentrates may be more affordable but include more lactose and fats.
• Purity and sourcing: Grass-fed, non-GMO, and no artificial flavors align with a clean label. NSF certification can indicate purity and safety.
• Digestibility: If lactose sensitivity is a concern, choose isolates or unflavored options labeled as virtually lactose-free.
• Taste and mixability: Unflavored powders require blending with flavors or beverages. Flavored options offer convenience but may include added sweeteners.
• Serving size and value: Bulk bags offer cost efficiency; ensure the scoop size and protein per serving meet your goals.
