Buying Guide
What matters most for muscle-building shakes
- Protein per serving: Look for 20–40g per serving to support muscle protein synthesis, depending on your size and activity level.
- Sugar and calories: Lower sugar options help manage daily intake; consider whether you prefer higher calories for mass gain or leaner profiles for maintenance.
- Protein source: Whey, casein, or blends offer different digestion rates. Mixed proteins can support both immediate and sustained amino acid delivery.
- Other nutrients: Added vitamins and minerals can aid recovery, immunity, and energy metabolism.
- Digestibility: Milk-protein isolates and ultrafiltered proteins tend to be easier on the stomach for many.
- Flavor and texture: Personal preference matters for consistency and adherence to daily goals.
