Only the Highest Quality Ingredients

ISO XP is made using cold-processed New Zealand whey isolate, which guarantees you will be getting the most naturally wholesome whey supplement possible. In addition, XP Labs uses Lactospore probiotics to bolster your immune system and digestive health. And to enhance the creamy, ice-cream-like flavor, a touch of Stevia has been added for sweetness and depth.

Supports Your Body

ISO XP is optimized to support you no matter what your goals are. The high concentration of protein, amino acids, and probiotics per scoop is the perfect combination for muscular growth, weight management, and general health supplementation. ISO XP is even a great choice for seniors looking to combat age-related muscle loss. There is no better protein out there!

100% Free of Hormones and GMOs

ISO XP is guaranteed to be free of rBGH, or Recombinant Bovine Growth Hormone. There are also no GMOs, no antibiotics, and no other undesirable chemicals. ISO XP is nothing but natural, healthy ingredients.

Only the Finest Ingredients


Lactospore is a type of probiotic which helps maintain a healthy balance of bacteria in your intestines. Lactospore uses naturally occurring microorganisms to restore the balance of intestinal flora whenever things get a little of-track – and because your gut is so very easily influenced by the environment, with everything from changes in your mood to different foods and bad weather causing adjustments, things can get off-track very quickly sometimes.

Sunflower Lecithin

The use of sunflower lecithin allows ISO XP to remain 100% soy free. Not only that, but sunflower lecithin is superior to soy lecithin when it comes to health benefits, as it is a far more natural choice. It is processed through a cold-press system, similar to the one used to make olive oil, and it is rich in choline and other essential fatty acids. Sunflower lecithin is used in ISO XP to help make the whey mix smoothly and easily, without sacrificing any of XP Labs’ exceptionally high standards. Source2


The small amount of stevia in ISO XP allows you to enjoy a richer, more full-flavored product without having to worry about any added sugars or problems with blood sugar regulation. Stevia has been extensively studied and is safe for use by people with type 2 diabetes, many of whom can benefit from exercise and weight loss. By creating a product that is delicious and appropriate for a wide range of people, XP Labs has made just a tiny bit of stevia go a long way. Source3

Whey protein increases cellular glutathione which in turn improves the free-radical fighting ability of your body. This should improve muscle recovery and overall health.

Published by Fox News, Sept 18, 2011


The researchers reported that the men consuming whey protein isolate supplementation saw improved muscle strength in the days following the muscle damage. The whey protein group also had less markers of muscle damage, which may be due to the potent antioxidant abilities of whey protein.

ISO XP has Amazing Benefits

Whether you are looking to perfect your physique or just wanting a bit of protein supplementation, ISO XP has a fantastic lineup of benefits for your body.

Grass Fed

Why choose New Zealand grass-fed whey? All dairy from New Zealand comes from free-roaming cows, who enjoy lush pastures and a natural, healthy environment. There are no antibiotics or hormone injections, and the cows never spend time in a smelly feedlot. The end product is pure, delicious dairy from healthier and happier cows. And because the milk they produce is some of the best in the world, everything made from that milk is also going to be premium quality. In other words: Start with the best, end with the best. That’s why XP Labs has chosen New Zealand grass-fed whey and That’s why you should, too.



Because the standards for New Zealand dairy are so high, you can rest assured that there has never been any GMO exposure in ISO XP whey. XP Labs has gone to great lengths to ensure the absence of GMOs in ISO XP so that you, the consumer, can be sure to have the most natural and wholesome product possible.

Stevia Sweetened

Stevia Sweetened

Stevia was chosen as a sweetener to enrich the ice-cream-like flavor of New Zealand whey without adding any sugars. Stevia does not have any impact on blood sugar levels and, as a result, is considered to be safe for diabetics and anyone else who may need to monitor their blood sugar regulation.

Gluten Free

ISO XP is safe for use by anyone who is gluten intolerant or otherwise has gluten sensitivities. Additionally, ISO XP is nearly 100% lactose-free, making it usable by almost all lactose intolerant people. XP Labs is dedicated to providing products which meet the needs of a wide range of users, and those who cannot consume gluten or lactose have not been forgotten!

Probiotic Enhanced

XP Labs has added probiotics to ISO XP in order to elevate the digestive benefits already present in whey. Probiotics help keep your digestive tract full of friendly bacteria, which promotes good whole-body health. The probiotics in ISO XP aid your metabolism and bolster your immune system to keep you going strong each day.

frequently asked questions

How do I use ISO XP?

Experts recommend 1 to 3 servings of whey protein each day for optimal results. One serving should be taken immediately following a workout, while the other two can be consumed in the morning and evening. Preparing ISO XP is as easy as adding one heaping scoop to your beverage of choice – we recommend milk or water – and mixing well. You can also add ISO XP to several recipes and food items, such as oatmeal, pancake mix, or yogurt.

Is grass fed protein powder better?

The New Zealand grass-fed whey in ISO XP is a cleaner, more natural choice for your protein needs in comparison to other protein powders. Why? The answer stems from the strict laws governing all of New Zealand’s dairy products. Not only are the cows producing the whey healthier and happier, but the whey itself is completely free of antibiotics, hormones, and other harmful chemicals.

Is whey protein isolate good for weight loss?

Yes, studies have indicated that whey is not only a top quality choice for keeping yourself satisfied throughout the day, but it can aid in your weight loss journey by activating your body’s natural powers of thermogenesis!

Does whey protein isolate have lactose?

ISO XP is approximately 99% lactose free. The lactose content is so low that most lactose intolerant people will have absolutely no problem enjoying the rich, creamy taste of whey. It can even be used as a substitute for milk in your cereal bowl!

Are there any side effects of taking ISO XP?

There are no known side effects of consuming whey. Whey protein is a safe, wholesome protein supplement made from dairy products. As always, read the label carefully and do not use ISO XP if you are allergic to any of the ingredients.

Hotte explains that the supplement is filled with amino acids, probiotics and wholesome nutrition and made from grass fed all natural New Zealand whey. The supplement provides protein supplementation that is designed to help with muscle growth, hormone regulation, fat loss and cellular health.


“Studies conclusively show that whey isolate is a healthy and easy to digest way to get the protein that you need on a daily basis,” says Hotte. “This protein supplement is great for those of you who are trying to focus on a high protein, low carb diet and who want to build muscle and eliminate fat.”

Hotte says that the supplement from XP Labs will go nicely with the Natures Harvest health food supplements that the company already offers. He states that it is the perfect choice for those who are looking to get the best sports nutrition, such as bodybuilders and athletes. Hotte stays that the protein supplement is also good for senior citizens who may not be getting enough protein in their daily diets, as well as hikers and those who workout on a daily basis. Protein is essential in helping to build muscle and avoid losing muscle when working out. Hotte says that the supplement is good for helping those working out to avoid losing the muscle that they are trying to build.


ISO XP is a popular nutritional supplement among professional athletes as well as dietitians and nutritionists, coaches and trainers and other fitness enthusiasts. Hotte says that the brand itself is synonymous with high quality and states that the protein supplement is made from only the highest quality of ingredients. He says that the process of creating the supplement includes cold processing whey isolate so users know that they are getting the most natural whey supplement possible.


He states that the manufacturer of the supplement uses Lactospore probiotics to boost digestive health and the immune system, making the supplement a good choice for anyone who suffers from regular digestive issues or who cannot generally take whey or protein supplements because of digestive issues. The whey supplement is designed to support the entire body with amino acids and high concentrations of protein.

Hotte says that the product is also free from GMOs and hormones, making it safer than other similar items on the market.


This is one of the reasons that the company chose to work with the supplement manufacturer XP Labs. Hotte says that they want to provide their customers with products that help them to get the bodies that they want, but only in the safest possible way. The supplement does not contain rBGH, a growth hormone, and Hotte says that there is nothing unnatural in the supplement at all, which is the main reason that the company chose to feature it.
