Why Choose Whey Protein Isolate?

Whey protein isolate is a refined protein source that provides essential amino acids needed to support muscle protein synthesis and recovery from exercise.* NutraBio uses a cross-flow micro- and ultra-filtration process to produce whey protein isolate while reducing fat and lactose.

Muscle Growth & Performance Support*

Protein provides the amino acids necessary for building and maintaining muscle tissue.* Consuming adequate dietary protein alongside resistance training helps support lean muscle development, strength-training goals, and exercise recovery.*

Recovery Support*

Whey protein isolate provides a convenient source of rapidly digested protein following exercise.* Each serving delivers 25 grams of protein along with naturally occurring essential amino acids and BCAAs to help support muscle protein synthesis and post-workout recovery.*
