Let’s investigate why ISO 100 Hydrolyzed Whey Protein is so beneficial for athletes and lean muscle building.

ISO 100 contains 25g of whey protein isolate per 30g scoop. This gives it a very solid percentage of 83.3%.



Whey protein isolate goes through more processing steps than whey protein concentrate to produce a higher percentage of protein content by weight, at 90% or more.

It sacrifices more fat and carbohydrates than whey concentrate to reach 90%. Isolate is considered more suitable for those of you aiming to build lean muscle without adding body fat for this reason.






Lean Muscle Building

Whey isolate is ideal for building leaning muscle because it has 90% or more protein content by weight and very low amounts of fat.


Post Workout Recovery

It’s ideal for post-workout recovery because it’s quick-digesting


Low Lactose Content

Whey isolate would be the best type of whey protein for those of you who are lactose intolerant.


Dymatize ISO 100 also includes hydrolyzed whey protein isolate.



Hydrolyzed whey is more of a niche than concentrate and isolate, and in some ways it’s superior.


What is Hydrolyzed Whey?

Hydrolyzed whey undergoes a process that breaks whey protein down into smaller pieces than concentrate or isolate does. These smaller pieces are referred to as peptides.


Hydrolyzed Whey Benefits

It’s even faster-digesting than isolate and concentrate.

There are arguments as to whether hydrolyzed whey is just another way to market whey protein but I wouldn’t necessarily agree. It’s beneficial after intensive workouts because it absorbs into your system quicker than the other types of whey.



Let’s delve a litter further into ISO 100 nutrition and break down each benefit.


1. Super-Fast Digesting and Absorbing

As we’ve already discussed, hydrolyzed whey digests and absorbs quicker than other types of whey proteins. This puts ISO 100 up there with the best whey protein powders in terms of digestion and absorption speeds.

It’s really important to digest and absorb protein as quickly as possible if you’re an athlete. Why? Because you need quick-digesting protein to prevent your muscles from entering a catabolic state after training for long periods.


2. Low Calorie Count

Do you want to build lean muscle and lose fat? ISO 100 is one of the best whey protein powders for this goal. Why? Because it’s made up almost entirely of hydrolyzed whey and contains 0g of fat and only 1g of carbs.


3. Amino Acid Profile

Dymatize ISO 100 contains 5.5g of complete aminos (BCAAs) on top of 25g of whey protein, which is great.


Amino Acids Benefits


Fasted Training

If you like to train in a fasted state, aminos are extremely important.

While it’s not too difficult to source aminos from natural dieting if you train in a fasted state, you run the risk of being amino acid deficient because you haven’t eaten for a long time.

Supplementing Dymatize ISO 100 protein enables you to train in a fasted state and get the aminos you need to prevent muscle breakdown after working out.


Decrease Muscle Soreness and Enable Long Workouts

Just to be clear, if you train for 45 minutes and eat plenty of meat in your diet, supplementing BCAAs aren’t necessary.

If, however you train in very intense sports like MMA, boxing, and cycling, you’re likely to go for long periods without eating. So you need to give your muscles as much amino support as possible.

As someone who trained MMA for a couple of years let me tell you, BCAAs are a great supplement and made a big difference to my performances during 2-hour workouts.

Not only did aminos enable me to do intense workouts several times a week by preventing muscle soreness, but they also helped me to lose weight on a calorie deficient diet and still perform at a high level.

Do you supplement aminos and whey protein separately? You don’t need to with ISO 100 because you essentially get two for the price of one!

Dymatize could have advertised a higher protein percentage but they were honest and kept aminos and whey protein separate. This is really important because lots of companies combine aminos and whey protein ratios together to make their protein percentage look better than it actually is.


4. Gluten Free

Irritable bowel syndrome is a huge issue in modern times thanks to processed foods and other causes. Many whey protein powders contain gluten, but not ISO 100.

Do you want to stay on the treadmill instead of the toilet? Make sure you purchase a whey protein supplement like ISO 100!


5. Banned Substance Tested

All Dymatize products are tested at LGC and are high-quality standards and athlete safety certified.

Supplement testing holds a great importance for those of you who are athletes. If you fail a drug test, your career could be over.

The sad thing is, many athletes fail drug tests due to contaminated supplements, not because they’re seeking to cheat the system.

Are you an athlete? It’s really important for you to purchase supplements from a company like Dymatize to avoid supplement contamination.

ISO 100 comes in 12 flavors. The Chocolate peanut butter and peanut butter flavors have rave reviews but my personal favourite is the birthday cake flavour.

You have lots of flavors to choose from either way! I’ve personally tried birthday cake, cookies and cream, gourmet chocolate, fudge brownie, and smooth banana, and they all tasted great!

ISO 100 is one of the best whey protein powders for mixing as well! It mixes almost instantly and doesn’t leave any clumps.

Is taste important to you? ISO 100 is up there with the best tasting whey protein powders.



Dymatize have been around for a long time and produce a broad range of health and fitness products. They’re best known for ISO 100 though, simply because it’s arguably the best whey protein isolate on the market today.
