What is Amino Z Casein Protein

In the world of protein, it can be easy to get caught up in the “whey” hype.

Sure, whey protein is an excellent muscle building supplement to utilise in your dietary program. However, if you’re serious about muscle mass and recovery then casein protein may be what you need.

Casein protein is a slow digesting protein. Why does digestion speed matter?

As protein breaks down, amino acids are released. Amino acids are the building blocks of muscle tissue. The longer that a protein takes to break down, the more amino acids are released into your body. The more amino acids being utilized by muscle tissue, the greater the chance of you reaching your muscle mass goals.

Not all casein proteins are made using premium standards. If you don’t want to take chances on quality and effectiveness, you need Amino Z Casein Protein.

What are the Benefits of Using Amino Z Casein Protein?

Packed with 24 grams of highly bioavailable protein, Amino Z Casein is the ideal morning, pre-workout, and evening supplement.

Made with Fonterra, the best protein in the fitness industry, Amino Z Casein Protein begins to release a steady stream of muscle building amino acids over the course of several hours. Compare that to whey protein, which only provides you with an hour or two, at most.

Taken as directed, Amino Z Casein Protein may be able to promote the following benefits:

May help protect current levels of muscle mass
May spike protein synthesis (a critical part of muscle building)
May support anabolism throughout the night
May boost recovery
May help with curbing appetite (1-3)

Who Should Use Amino Z Casein Protein?

Amino Z Casein Protein is the ideal supplement for any gym goer who is looking to support muscle gains and overall recovery. With the flood of amino acids that you’ll get after using this casein protein, your muscles will be getting the support they need for maximum results.

Even if you aren’t looking to put on serious muscle, Amino Z Casein Protein can still be a helpful part of your fitness journey. It makes a perfect meal replacement shake, helping to curb appetite while providing necessary muscle building nutrients.

Tasty casein protein

By Hashem reviewed on 2/10/2021

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

Great as a normal shake or mixed with less milk/almond milk to make a pudding consistency, almost like a mousse. Makes a great dessert if you mix in a bit of extra ingredients. I add things like blueberries, dark chocolate, peanut butter...

Bought the chocolate flavour. Nice with water. Doesn’t mix 100% properly but same with other casein. Give it a hard enough shake and it usually fixes this up.

I like no sweeteners added to protein powders, but the chocolate one would have been better with something like xylitol
