Buying Guide: Key Purchase Considerations
- Protein type: Isolate vs. concentrate vs. blends. Isolates deliver faster absorption and fewer carbs; concentrates may contain more lactose and fats.

- Flavor vs. unflavored: Flavored options enhance taste but may include sweeteners or fillers; unflavored options offer customization with your own ingredients.
- Allergen considerations: Look for lactose sensitivity, soy-free, gluten-free, and non-GMO labeling if applicable.
- Certifications: NSF or other third-party certifications lend credibility for purity and safety claims.
- Digestibility: Some products advertise fast absorption and low bloating; consider lactose content and digestion comfort.
- Usage context: Pre-workout, post-workout, or meal replacement—choose a product aligned with your routine and protein needs.
