Buying Guide
How to choose non-lactose whey protein:
- Protein source: Look for whey isolate or hydrolyzed whey for the lowest lactose content and fastest absorption. Isolates typically have less lactose than concentrates.
- Ingredient purity: Favor products with minimal additives, especially if lactose intolerance is a concern. NSF or third-party certifications add quality assurance.
- Carb and sugar content: If you monitor carbs, select zero-carb or low-carb options and check serving sizes.
- Flavor and mixability: Flavored varieties may appeal to daily use; unflavored options offer flexibility in recipes and beverages.
- Digestive considerations: Some products include enzymes or lecithin to aid solubility and digestion; consider your tolerance to lactose and dairy proteins.
- Allergen awareness: If you have soy or gluten sensitivities, confirm that the product is free of those ingredients and cross-contamination risks are minimized.
- Intended use: For post-workout recovery, prioritize higher protein per serving and fast absorption; for meal replacement, consider additional calories and nutrients.
