Buying Guide

Protein source and digestibility

Choose between animal isolates (beef, micellar casein) and other proteins based on digestion speed and dietary tolerance—beef isolates and micellar casein offer different amino-acid release profiles

Check lactose and allergen status

If you’re lactose intolerant or avoiding dairy, prioritize lactose-free or whey-free options; several beef isolates are explicitly lactose-free

Compare protein-per-serving and isolate status

Isolates typically provide higher protein concentration per serving and lower carbs or sugars, which can improve value for muscle-building goals

Look at added sugars and carbs

Low-sugar or carb-free formulations reduce unwanted calories and support body-composition goals; many isolates and specialized formulas advertise sugar-free or low-carb profiles

Flavor and use case

Select flavors and textures that suit your routine—micellar casein is better for slow overnight recovery, while isolates work well immediately post-workout
