Buying Guide
What to consider when choosing a high-protein powder:
- Protein type: Whey concentrate, isolate, or blends. Isolates generally have higher protein per serving and less lactose, while blends can offer more complete amino profiles at a lower cost.
- Protein per serving: Match to your daily protein goals. Higher per-serving protein helps with larger muscle-building needs or meal supplementation.
- Amino acid profile: Look for essential amino acids and BCAAs, especially leucine, which supports muscle synthesis.
- Sugar and carbohydrate content: Lower sugar and carbs suit lean-muscle goals and cutting phases; higher sugar may benefit those needing quick energy.
- Digestibility: Grass-fed or minimally processed options can be gentler on the stomach; consider artificial sweeteners if sensitive to taste.
- Allergens and dietary preferences: Gluten-free, lactose-free, soy-free, or vegan options should align with your needs.
- Flavor and mixability: Read reviews for texture and taste; some powders mix better with water or milk.
