The highest protein content on the market

We've raised the bar with Impact Casein. When you buy protein powder you want PROTEIN. So we give you lots of it. Impact Casein packs in 26.5g of protein in a tiny 30g scoop. So when we say PURE protein, we mean it. No one else comes close.

How much is everyone else offering?

Flip to the back of any protein container and take the amount of protein per serving and divide that by the grams per serving. That’s the protein percentage being offered. You may be surprised at what you find. Our market study found that the average casein protein has only 72% protein per serving (Impact Casein comes in at 88%). That's a lot of filler without very much protein.

We don't hide behind misleading serving sizes

We offer lots of protein in a small serving size. Once a protein powder serving size is over 30 grams, it's a strong indicator that fillers are being used. Our market study found protein powders that were upwards of 39 grams per serving. These companies often offer roughly 24g of protein per 39g scoop, hoping you won't notice. There is no excuse for that.

Made with only 5 ingredients

Impact Casein is made with just 5 ingredients. Fewer ingredients means more purity and more protein. The average casein protein in our recent market study had an average of 19 ingredients on the ingredients list. That's simply unnecessary.

What are the 5 ingredients?

Ingredient #1: Micellar Casein Protein: Low-temperature micro-filtered protein.
Ingredient #2: Natural & Artificial flavor: Turns unflavored protein into 1 of 13 delicious flavors.
Ingredient #3: Cocoa, in our chocolate-based powders.
Ingredient #4: Xanthan Gum: Adds texture and body to the shake.
Ingredient #5: Sucralose: A safe non-sugar sweetener.

26.5g of protein, 3.5g of the other stuff, for a compact 30g scoop. The way it should be.

Around the clock gains

If you want to maximize gains but the thought of setting an alarm at 3am to fuel your body with the protein you need does not sound appealing, Impact Casein can help. Even if supplementing with a regular whey protein concentrate or isolate, there are several hours where your muscles experience starvation and apathy. Impact Casein shines during these periods, such as between meals or after bed, when it’s either not convenient or possible to stop and refuel your body. Adding Impact Casein to the mix provides a sustained supply of protein absorbed over a 7-hour period.

What's the science behind Impact Casein?

Impact Casein comes from a premium grade, slow release protein derived from ultra-filtered skim milk. It uses a low temperature ultra micro-filtration process ensuring the casein protein retains its natural micellar structure and functionality while minimizing denaturing. This means that when consumed, the casein forms a gel-like substance in the stomach making it the slowest digesting protein available. That's what leads to Impact Casein's drip-feeding nature of protein and amino acids to muscles during times of rest.

Say NO to protein spiking

You go to the store and pick up your favorite tub of protein. It says that it has a whole bunch of great things like taurine, glycine, glutamine... and sometimes even creatine. These are additional supplements you know and trust so you figure why not. If you get them in addition to your protein then all the better right?

Not quite.

There have been a number of lawsuits in the industry claiming some companies doing such things aren't adding these extra ingredients in addition to your protein. They're adding them INSTEAD of your protein. The nitrogen from the amino acids like taurine and creatine are picked up by the same tests that test for protein content, which means it's easy to pass like there is more protein than there actually is. Also, ingredients like taurine and creatine make for cheap substitutes to protein. It's a very deceptive way of seemingly offering better, while actually offering much worse. Impact Casein does not have any unnecessary added amino acids.

Nutrition Facts


Add one scoop of Impact Casein to 250ml of water, shake and consume immediately. Use less liquid for a thicker and stronger tasting shake. Use milk for a creamier tasting shake. We recommend one serving 30-60 minutes before bed to deliver a sustained supply of protein during sleep. Impact Casein can be consumed between meals as required. Experts suggest a minimum 1 gram of protein per pound of body weight daily to promote lean muscle growth.
