ARO™ Casein – 49 servings per container

  • 24 grams of quality micellar casein protein
  • Enhanced with Aminogen®--a patented protein-digesting enzyme blend
  • With added MCTs
  • Mixes great – makes smooth, creamy shakes
  • Natural vanilla flavor – no added sugar!
  • Best-tasting casein – no chemical aftertaste

What is ARO™ Casein?

Feed your muscles with top-quality ARO™ Casein—a superior source of slow-digesting, natural casein protein enhanced with MCTs and Aminogen®, a patented protein-digesting enzyme blend.


Each scoop delivers 24 grams of pure micellar casein protein in an easy-to-mix, natural vanilla flavored powder—no added sugar, no hidden chemical ingredients, no bitter chemical aftertaste. Just add to 8 oz. of water for a smooth, creamy protein shake with amazing taste.


Casein protein, derived from dairy milk, is rich in muscle-supporting and maintaining essential amino acids. Unlike whey protein, it’s slow to break down, allowing delayed amino acid release for a steadier stream of nutrition over a longer period of time. Drink an ARO™ Casein protein shake between meals or before bed when food intake is halted for the night.


Why choose Vitacost ARO™ Casein?

  • 24 grams of natural micellar casein protein per scoop
  • Includes a patented digestive enzyme blend – Aminogen® -- plus MCTs
  • Best tasting – no added sugar or chemical aftertaste
  • Smooth mixing – no clumps
  • 49 servings per container -- incredible value!

Good Stuff A nice nutritious snack or pre-workout food. What makes this different than whey protein? It will not digest as fast, leaving me hungry. Helps me maintain a consistent energy level. I think this is one of those "best kept secrets" we all hear about. January 22, 2015
NOT a "Natural" Casein This product is filled with artificial sweeteners! How can VitaCost label this as "Natural" when it is NOT natural? December 20, 2014
Excellent value One of my favorite proteins. It taste good, has plenty of protein, and is a much better value than most casein proteins out there. December 11, 2014
One of my favorite proteins Good vanilla taste. Nice texture to make protein pudding. And I like the Casein form to use at night before bed. The only thing that would make it perfect would be if it was sweetened with stevia instead of sucralose. November 11, 2014
too sweet and artificial.... I wanted a good casein powder to have after dinner for desert and to stop snacking and so that body would have protein available to it all night long. This pretty much delivered on this goal. Mixibility is very good. Tasted like cheap coffee creamer. Wasn't too bad if you mixed it with something sour like Vibrant Health Green Vibrance Powder. At this point in time I don't know if I will re-order. I haven't tried enough different caseins to have an informed opinion. July 7, 2014
