Buying Guide: Key Purchase Considerations

• Extraction and processing: Look for cold-filtration or ultra-filtered isolates that preserve protein integrity and limit lactose, fats, and fillers.
• Flavor vs. unflavored: If you want zero artificial sweeteners, prioritize unflavored or naturally sweetened options. Some flavored varieties may still be free of artificial sweeteners; verify ingredients.
• Lactose tolerance: Even “unflavored” isolates can have trace lactose. If dairy sensitivity is a concern, check lactose levels or choose brands highlighting low lactose.
• Sourcing and ethics: Grass-fed and Truly Grass Fed certifications indicate pasture-based sourcing and natural dietary practices; this can influence digestibility and sustainability.
• Amino profile: Check protein per serving and BCAA content to align with training goals and recovery needs.
• Digestive comfort: Some isolates are designed to be easier on the stomach, with reduced lactose and gentler processing.
• Allergen and certification considerations: If you need gluten-free, kosher, or soy-free options, confirm certifications on the product page.
