Product Overview

Protein Advisory: ALLMAX protein products contain absolutely zero protein sourced from China. IsoNatural is 100% sourced from the United States.

IsoNatural is a pure whey protein with no artificial flavor, no sugar, no sweetener and no color added. It's the ideal protein supplement for those looking for a natural option with no added artificial flavors or sweeteners. IsoNatural is 100% pure and a natural whey protein.

"IsoNatural contains no artificial flavors or sweeteners."

How is IsoNatural Made? IsoNatural protein powder is extracted through CTP™ (Cold Temperature Process) Microfiltration; this is a Cross-Flow Microfiltration (CFM) process that removes the larger, less absorbable protein molecules while filtering out fat, lactose and ash which are normally present in whey concentrates and other lower quality protein powders.

"It is extracted through CTP™ (Cold Temperature Process) Microfiltration."

The filtration membranes used for in the CFM process are extraordinarily fine and have the ability to remove even more lactose, ash and fat than the process of ultra-filtration which is used for lower quality whey protein products. Using this sophisticated process ALLMAX is able to produce IsoNatural, a superior Ultra-Pure Protein that maintains an optimal macronutrutient ratio, yielding 28 g Protein, 1 g Carbohydrate and 0 g of fat.

"IsoNatural contains 0g of fat per serving!"

CFM is one of the best methods to extract protein on the market today. This manufacturing process is far superior to some of the others to process an extremely pure isolate. The whole process takes place at a chilly 4 degrees Celsius, or 39 degrees Fahrenheit and leaves almost 100% of the protein and peptides in tack it also yields to highest amount of undenatured (bio-active) protein available.

Our whey protein isolates are manufactured by "chilling" or low temperature microfiltration process and dried by indirect heat. The low temperature microfiltration process allows the Iso-Chill whey protein isolates to provide undenatured protein with a full balance of bioactive whey protein fractions, including immunoglobulin, lactoferrin and glycomacropeptides (GMP).

"The low temperature microfiltration provides undenatured protein with many bioactive whey protein fractions."

Other whey processing technologies using higher temperatures cause irreversible unfolding of the protein fractions that can drastically reduce the biological activity of the protein. Based on solubility at pH of 4.6, ISOFLEX Whey Protein Isolate has a mere 3% denatured proteins, which is approximately 10% less than ion-exchange whey protein isolates and typically less than other microfiltration whey protein isolates. ISOFLEX Whey Protein Isolates also contain up to 12 times more native GMP than ion-exchange whey protein isolates.

How is Whey Protein Isolate Produced?

To produce whey isolate the protein goes through the following steps:

  1. Fresh milk is tested by Quality Assurance experts.
  2. The curd portion of the milk fat is separated out for cheese.
  3. The watery liquid portion that remains is filtered through a process called microfiltration process; to remove lactose and ash.
  4. The concentrated liquid goes through the cross flow microfiltration process. Which is where the whey is isolated by being driven through extremely fine ceramic membranes. This process eliminates the need for harsh chemicals used in other processes.
  5. The whey is dried and water is removed.
  6. Finally, pure whey protein isolate is packaged in its container.

All of these steps are performed at a pharmaceutically licensed manufacturing facility to ensure quality and integrity. Every ingredient added and every lot produced is independently lab tested for purity and quality to ensure consistent quality every time.

As an isolate IsoNatural contains 93% of pure whey protein. Whey protein concentrates and blends only contain about 75-85% protein as they also contain lactose and fats. IsoNatural represents the highest in Whey Protein Isolate supplementation yielding an amazing 93% pure (bioactive) protein per scoop! It is also 98.5% lactose free, which makes it an ideal choice for those who are lactose sensitive.

"IsoNatural contains 93% pure whey Protein."

IsoNatural protein powder contains the highest concentration of protein; due to the Proprietary CTP™ Cross-Flow Microfiltration Process. IsoNatural mixes extremely easily fur use in smoothies, regular juice or any recipe that calls for protein

Furthermore, IsoNatural is manufactured in the US with US Dairy Cows. ALLMAX protein products contain absolutely zero protein sourced from China. IsoNatural is 100% sourced from the United States.

Edit to my previous post. The new style container of Chocolate DOES contain Prebiotic's like the old style container. *Comparing the profiles of the old style container Vanilla vs the new style container Chocolate there is a difference as someone else posted and pointed out. The old style listed WAY more information including the Amino Profile where as the new style does not include that information, nor does it show the cholesterol.

I purchased this product multiple times in the past and I loved it !!But with the new changes I have to say I'll be looking elsewhere. It was ONCE cold processed which I'm a huge fan of . But Allmax decided to go for a higher protein content By filitering by Ion Exchange(2017 current) . It also no longer contains Probiotics and Amino profiling on the labeling and I'm sure there's more I haven't noticed yet . needs to update the product information because ALLMAX made some bad changes to this product and if the page was updated with correct information I would have looked for a different protein that meets my standards . Update the product information !!!!


I have tried a few different protein powders over the years and so far this one is my favourite. It mixes very well and taste amazing with plain old water or almond milk. Pros; - Taste Great - Low Calories - High Protein per scoop 27g protein for the one 30g scoop - All natural ingredients Cons; - Nothing so far

Got this as a sample from allmax. I had this post workout with 1% milk. I really like the idea behind the natural ingredients however there was something that was just a tad off on the flavor for me. Not sure if it was the natural sweetener but would be interested in trying another flavor.
