Isoflex: Under The Microscope

The four systems of ISOFLEX:

1. WPI (Whey Protein Isolate) Complex [WPI Fortified]: CTP (Cold Temperature Process), cross-flow microfiltered whey protein isolate, WPI (97% Whey Protein Isolate). This high-quality whey protein isolate complex can help you reach your body-shaping goals.

2. Glutamine Complex [GLUTASURE TECHNOLOGY]: Naturally occurring glutamine peptides - 100% fermented source lactoferrin. Designed to improve recovery and provide immune support.

3. NOS Complex (Ultra-Flow Delivery): contains arginine, taurine, and folic acid. Designed to increase blood flow and increase nitrogen and whey peptide delivery. It can also boost nitric oxide levels, thereby speeding up recovery and protein delivery to muscle tissues.

4. IS Complex [Rapid Absorption]: Alpha Lipoic Acid (ALA), d-Pinitol, and 4-Hydroxylsoleucine. Designed to increase protein uptake and insulin support.

How is ISOFLEX Made?

ISOFLEX protein powder is extracted through CTP (Cold Temperature Process) Microfiltration; this is a Cross-Flow Microfiltration (CFM) process. CFM is one of the best methods to extract protein and 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 yields the highest amount of undenatured (bio-active) protein available. The filtration membranes used for in the CFM process are extraordinarily fine and have the ability to chemically shear and purify creating an extreme protein isolate as compared to ultra-filtration which is used for lower quality whey protein products. Other whey processing technologies using higher temperatures cause irreversible unfolding of the protein fractions that can drastically reduce the biological activity of the protein. Using this sophisticated process ALLMAX is able to produce ISOFLEX, a superior Ultra-Pure Protein that maintains an optimal macronutrient ratio, yielding 27 g Protein, 1 g Carbohydrate and between 0.2 g and 0.5 g Fat (slight variations with each flavor).

These CTPand CFM processes purify the protein and filter out unwanted ingredients including fat, ash, lactose, and larger less absorbable protein molecules, all of which are normally present in whey concentrates and other lower quality protein powders.

How is Whey Protein Isolate Produced?

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

Fresh milk is tested by Quality Assurance experts.

The curd portion of the milk fat is separated out for cheese.

The watery liquid portion that remains is filtered through a process called microfiltration process; to remove lactose and ash.

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.

The whey is dried and water is removed.

Finally, pure whey protein isolate is packaged in its container. This all takes place at a licensed manufacturing facility. All ingredients have been lab tested for purity, quality, and consistency.

Many competitors produce protein concentrates that are only 75-85% protein as they also contain lactose and fats. An isolateISOFLEX contains 90% of pure whey protein. ISOFLEX represents the highest in Whey Protein Isolate supplementation yielding an amazing 90% pure (bioactive) protein per scoop! It is also 98% lactose-free, which makes it an ideal choice for those who are lactose sensitive. ISOFLEX is 100% sourced from the United States ISOFLEX and is manufactured in the US with US Dairy Cows.

    When I first tried IsoFlex I was kinda skeptical but one of my lifting buddies conviced me otherwise. And I donot regret it! This stuff is unreal. The taste is unbelievlibly good for a protien shake. Its thin like choclate milk and goes down smooth without any after taste. And it has 27g of protien per scoop and a ton of amnio acids! It also has helped me power through workouts and iv noticed quicker recovery times. Easily the best whey isolate on the market!

    I just finished my first tub of isoflex and I am impressed. Simply put the taste is amazing. No after taste, no side effects, nothing. Just a pure, easy to drink, shake. Isoflex also has about 20g protein per scoop with only 111 calories, 0g fat, 2g carbs. I have gained strength, muscle mass and noticed quicker recovery times. Try a 2lb tub if you’re unsure and I guarantee you’ll love it.

    I have been using this product off and on for years. I always go and try other things just see if it works. I have used many different protein powders and as a personal trainer. I try and stay up on the lastest protein supplement. However, I have to say this stuff is great. I have seen my best results using this product. I reccomend it to all of my clients who are trying to put on quality size. Anybody that says protein is protein is a moron.

    Best on the market.
    Best flavor, with real bits of strawberry, Chocolate chips or whatever flavor you get.
    It’s a bit pricey but it’s totally worth it!
    Such a clean protein at this stuff beats anything I’ve ever tried my entire life.
    This comes out to be about 90% pure!

    I was in need of a new protein since I was tired of the old one and had actually quit using it. A friend of mine recommended this protein because of the low carb and low sugar content as well as for the 27g of protein, 90% whey isolate formula and taste. I bought it and when I tried it the next day after my workout session I became addicted! I have the peanut butter chocolate flavor and it’s the best protein I have ever tasted. I use it to make protein bars as well as just drink it with water or almond milk. I recommend this protein to everyone now!

    I like the product very much. It is clean and works great. I am on my 5th 5-LB jug. I go through a 5LB jug every two weeks I like the chocolate peanut butter. Wish they carried the chocolate mint. I would recommend this product if you can afford it.
