NutraBio Muscle Matrix is a blended protein formula combining 55% whey protein isolate and 45% micellar casein — two milk-derived protein sources that digest at different rates — delivering 25 grams of complete protein per serving.*

The whey protein isolate fraction is rapidly absorbed, providing a quick rise in amino acid availability. The micellar casein fraction digests more slowly, helping to sustain amino acid levels for an extended period — making Muscle Matrix a versatile option for use throughout the day or before sleep.*
