Buying Guide
- Protein purity and ingredients: Consider whether you want single-ingredient organic whey or a formula with minimal additives. Unflavored options offer versatility, while naturally flavored options reduce the need for sweeteners.
- Sourcing and certification: Grass-fed and pasture-raised claims are meaningful if you value animal welfare and sustainability. Look for third-party certifications such as Informed-Sport, A Greener World, or Truly Grass Fed.
- Digestibility and lactose content: Isolate powders typically have less lactose, which benefits digestion. If you have lactose sensitivity, check the product’s lactose content and processing methods.
- Protein per serving and calories: Compare protein grams per scoop and total calories to align with your diet. Higher protein per scoop supports lean muscle goals.
- Allergies and restrictions: Check labels for soy, gluten, or dairy cross-contamination, especially if you have sensitivities.
- Flavor and mixability: If you dislike the taste of unflavored powders, consider lightly flavored options or those described as easy to mix.
- Price and value: Higher certifications and cold-processing often accompany higher price. Weigh certification and ingredient quality against budget.
