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.

This is currently my favorite, go-to protein powder! I bought the Vanilla flavored, which is not too sweet or overbearing when doing my shakes. It just gives the right amount of sweetness it needs! I also like the fact that it doesn't contain any sucralose, which is what I was looking for when researching and the powder quickly dissolves without leaving any clumps or powdery chunks. I have been using this for only two weeks and hopefully will see some gain thereafter but so far so good! I highly recommend this product for it's mainly naturally ingredients and great taste.

Super good whey protein. If you are going to buy an isolate, make sure it is cross filtered like this is. Don't waste your time on chemically separated isolates. That's asking for health problems later on down the road. This is a legit protein powder. Sweetened with Stevia, so you wont get headaches or go through withdrawals like you would with a product sweetened with chemicals. It also has no artificial....well, anything. So it's just protein and stevia. What more do you really want? Mix-ability is great. Taste is great...for vanilla. I cooked with it, (pancakes and waffles) and it was really good there as well. Overall, the only animal based protein worth buying.

I originally purchased the 2lb natural, which came into a black box and I truly loved it (great taste and very easy to dissolve into water). When I purchased the 5lb the following time, the SAME proteins came in a white box. The ingredients were different as they included 1% soy lecithin (non-GMO free). They did not dissolve well into water and they did not taste god at all! They tasted really chemical. I suppose AllMax Nutrition has hanged the formula, worsening it instead of making it better!! Sadly, I had to return the product. Too bad, as the previous ones were so much better. Now I have to search for another brand.

Great protein when counting carbs and calories. I love that the natural falvor has no sweetness to it but after a while the fact that it doesnt taste like anything gets kind of old. However, i'll definitley be reordering and maybe get the flavored ones to rotate. I did notice this protein did not upset my stomach or any of the inner workings which is quite awesome! Probably a life customer now!

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.

Great flavoring for a natural protein, I never use natural protein powders because I've never had any issues with taking any whey powders but after taking and reading about Iso-Natural I would certainly use it again. If whey that has dye and flavoring gives you stomach issues or you just don't want to use it, Iso-Natural would be a great option for you!

This is an all natural option from Allmax for their protein powder, and has natural flavor and sweeteners with no artificial colors or dyes. It has comparable ingredient profiles to other protein powders, all while still being natural. The chocolate peanut butter flavor is great, especially for an all natural product. This is perfect for those looking for a healthy, natural option for protein powders!
