PROTEIN TO TIE YOU OVER
Casein is a slower-digesting protein, designed for the times you’re not eating.
It’s developed in-house with the same focus on flavour and performance, so it’s something you’ll actually stick to, not just get through.
Simple, effective, and built to support you over longer periods without food.
WHY AMINO Z CASEIN?
• Slow-digesting protein, ideal before bed or between meals.
• 23g+ protein per serve.
• Works excellently in baking or cooking.
• Naturally sweetened with thaumatin = no weird aftertaste.
• Developed in-house with a focus on flavour and consistency.
FLAVOURS
Chocolate: Smooth, familiar, and exactly what you expect when you think of chocolate protein. More on the confectionery side than dark, with a balanced sweetness that makes it easy to have regularly. Sweetness Scale: 3/5 Medium.
Vanilla Ice Cream: Creamy, lightly sweet, and super easy to pair with just about anything, or have on its own. One of those flavours you don’t get sick of. Sweetness Scale: 3/5 Medium.
Unflavoured: Neutral with a slight milky note. No added flavours or sweetness, so you can mix it into whatever you like without it getting in the way. Not exciting, but that’s the point. Sweetness Scale: 0/5 None.
Below we have answered some commonly asked questions about this product.
What is Casein protein?
Casein protein is a protein found in cow's milk. When carrying the same amino acid profile as whey protein, casein protein is absorbed at a different rate.
Casein protein is a slow-releasing protein. In other words, after ingestion, your muscles will be 'drip-fed' casein for several hours. Casein protein is often considered 'anticatabolic' as it provides a steadier stream of acids and protein supply to prevent muscle breakdown.
What percentage of casein is the Amino Z Casein?
The sole protein source of our product is milk protein concentrate, thereby our product contains 80% casein and 20% whey.
What does the research show for casein protein supplementation?
1. Casein ingestion before sleep improves post-exercise overnight recovery, according to a 2012 study. [1]
2. Casein protein supplementation may increase lean muscle mass. [2]

[2] Tsutsumi R, Tsutsumi YM. Peptides and proteins in whey and their benefits for human health. Austin J Nutri Food Sci 2014;1(1): 1002.
When should I take casein protein?
Since casein protein is slower digesting we recommend consuming it before long fasting periods (i.e periods whereby you're not consuming nutrients or food for 4+ hours). Examples include before bed or as a final meal before fasting.
What does Casein taste like?
Casein is generally considered to have a pleasant taste. It should be noted that casein is thicker than standard whey protein.
Why is this product so much cheaper than similar products on the market?
Many other brands incur a high degree of costs associated with producing products. It is not uncommon for a product to be produced by a third-party manufacturer and then shipped (or imported) to a wholesaler. The wholesaler then sells to a retail store, who on-sells to the customer. The end result is that often four separate businesses are taking profits at each stage (the brand itself, the manufacturer, the wholesaler and the retailer).
We take a very different approach which allows us to keep our cost structure down and we pass those savings on to you, without sacrificing product quality.
We have our own purpose-built manufacturing plant located in Sydney Australia and we sell directly to you. This eliminates all additional parties from the process, thereby eliminating a lot of unnecessary costs.
The significant cost savings we incur allow us to invest into high quality ingredients while still offering a significantly cheaper final product.
I haven't tried this product before. What if I don't like it?
Because we manufacture this product ourselves, we believe that the onus is on us to produce a high quality product that you're going to love.
That's why we have our 110% Guarantee. Basically if you try it and you don't love it, just reach out to us. You can receive a 110% store credit, or a full refund.
