Elite Multi-Source Protein for Athletes

Proteins come in a variety of forms. Sources like whey are ideal around workouts when you want aminos - fast. Casein proteins are better between meals and before bed when slower delivery, over several hours, is preferred. Moderate-release proteins like egg and goat's milk are easily digested and contain all of the essential amino acids, which makes them great choices most other times.*

  • Now with 8 sources, including Native Whey Isolate and Native casein
  • 24 g full-spectrum protein
  • Elite blend of fast, intermediate, and slower digesting sources
  • Premium proteins including whey isolate, micellar casein & egg albumen
  • Over 5 g BCAAs (leucine, isoleucine, valine)
  • Little fat or sugar
  • Instantized to mix up quickly, fully, and easily
  • No banned substances - safe for sport

My review was deleted for some reason. SO I will write it again. Good protein with a great taste and it mixes really well. Its hard to find a protein that actually tastes good with just water. This hits the spot for sure. However my only complaint is for the first time ever, in my 10 years of using protein, I experienced nausea. And not just like oh my stomach is a bit upset. But like terrible I had to lie down bad. It was the worst I have ever experienced. I am hoping it goes away because the taste is really fantastic. If my stomach gets used to the product I will definitely continue using it because it really does taste that great!*
