Isopure: An Overview

For over three decades now, Isopure has dropped nutritional supplements that come with clean, pure protein. This points towards their use of high-quality, 100% whey protein isolate with little to no fats or carbs.

Isopure’s line of protein powders is formulated to help you gain lean muscle, pack on some size, increase strength, or lose weight, depending on your preferred supplement.

Some of their popular protein powder bestsellers include the Isopure Zero Carb that contains 25 grams of whey protein isolate for every scoop.

Aside from protein powders, other supplements that this manufacturer has developed include glutamine, amino acids, and creatine monohydrate, among others.

Isopure Zero Carb Protein Powder Ingredients 

Compared with the company’s highly popular Whey Protein Isolate supplement, the Isopure Zero Carb has a very similar macronutrient profile with the former. In fact, they both have 25 grams of protein for every scoop and with very minimal to zero carbs and fat.

This Isopure Zero Carb protein powder review further looks into what makes this supplement even more special. 

Whey Protein Isolate

Firstly, one scoop (about 30 grams) contains 25 grams of protein with just 1 gram of carbs and half a gram of fat. What makes this product remarkably low on carbs and fat is that it comes from pure whey protein isolate. 

Whey protein isolate has already been filtered much more than whey concentrate. Therefore, more fats and lactose have been removed. It has now a higher percentage of protein and can be absorbed much faster than whey concentrate.

It’s also very low in lactose so it has multiple benefits for you if you’re having issues with dairy products. Plus, it’s loaded with essential amino acids that work wonders for muscle growth.

The whey protein isolate content in the Isopure Zero Carb supplement sure packs in an incredible punch. It may have missed out, though, on some of the nutritional benefits present in products that have whey concentrate. For instance, whey concentrate has a couple more grams of fats and carbs that contain healthy nutrients to actually decrease body fat, like the CLAs.

Another issue you may find is that the manufacturer recommends for users to consume 2 scoops for 1 single serving. If you’re consuming 2 scoops, that makes it 50 grams of protein. 

Some do not recommend consuming this amount all at once because it’s such a considerable serving size. It will go beyond your body’s ability to digest and absorb 30 grams of protein within 3 hours.

However, it also depends on how active you are and how much muscle you have gained.

The more physically active you are, the greater amount of protein your body needs. Also, the more muscle you have, the higher amount of amino acids your body needs so you can maintain these lean muscle gains. You’re likely to have more storage in your body to keep these absorbed proteins and nutrients in reserve.

Vitamins and Minerals

Next, the impressive ingredient list is also comprised of an excellent amount of vitamins and minerals.

These include vitamin A, vitamin C, vitamin E, vitamin K, vitamins B6 and B12, thiamin, niacin, riboflavin, folic acid, biotin, pantothenic acid, iodine, magnesium, zinc, phosphorus, selenium, copper, manganese, chromium, molybdenum, and chloride. One serving (2 scoops) will contain 50% of your recommended daily value of most of these vitamins. 

What happens if you’re having two servings per day? You’re just about getting a full 100% of your daily value in a blend that’s formulated to naturally increase your energy and improve your health. 


Similarly important is the addition of L-Glutamine, which is highly recommended for your muscles’ repair and recovery. It’s beneficial for athletes, bodybuilders, and weight lifters who frequently put themselves through intense workouts.

Other Ingredients

Other ingredients include sucralose as sweetener, xanthan gum as a stabilizer, and soy lecithin for mixability.

One thing I would have preferred to include in the Isopure Zero Carb protein powder is a good blend of digestive enzymes. This will help in breaking down the proteins. You’ll have an easier time absorbing these nutrients and avoid gut-related issues, like gas and bloating.

For the most part, the Isopure Zero Carb protein powder is a superb way of boosting your protein intake without unnecessary fat or carbs. You can have this supplement as part of a low-carb keto diet plan.

Overall, if you’re looking to lose fat while retaining some lean muscle, the Isopure Zero Carb protein powder can be a great addition to your fitness and nutrition program.

How Effective Is the Isopure Zero Carb Powder?

Based on my own experience plus positive reviews from users all over the world, the Isopure Zero Carb is highly effective for muscle building and growth.

Protein Intake

Thanks to whey protein isolate, you get large amounts of amino acids that are easily and quickly digestible. Because these amino acids are so sufficient, whey protein then promotes more rapid and effective muscle growth.

Keep in mind that you can only achieve muscle gains if the rate of building muscles is higher than the breakdown of your muscle protein. 

The Isopure Zero Carb protein powder is best for athletes, bodybuilders, weight lifters, and those who are committed to building lean muscle.

Although it can be used for weight loss, it’s quite possibly not best recommended for this goal. There are many other supplements out in the market that will yield more effective results for losing weight.

Muscle Recovery

In addition, its glutamine content can help improve recovery even after intense exercises. You won’t end up feeling too sore or fatigued. It also prevents your muscles from being eaten up and remains a primary energy source for the immune system.

That’s why it’s a great addition to the Isopure Zero Carb especially if you’re used to tough, grueling workouts. You’re not only building muscles but you’re repairing them as well.

Highly Versatile Protein Powder

All in all, who can benefit from this protein powder? Just about anyone who wants to raise their protein intake with carbs at the minimum. 

If you’re looking for extra nutritional support, the Isopure Zero Carb protein powder is also a good option for you. That’s because aside from the hefty protein amount and lack of carbs, you’re getting a wide variety of vitamins and minerals as well. 

If you frequently go through intense training, this supplement will do you good as well, thanks to its essential amino acids and glutamine content.

For people who are on the sensitive side, this protein powder could be a friendly alternative too as it’s free from lactose and gluten.

How to Take Isopure Zero Carb Protein Powder

As recommended by Isopure, you take 2 scoops of powder and mix it with 12 ounces of water using a shaker or blender. You can have it as a pre-workout drink, or between meals as a quick, nutritious boost for your protein intake. 

Taste and Mixability

I have tasted the Dutch chocolate flavor. I have to say, the Isopure Zero Carb protein powder has a strong, sweet taste so it works well with just water. If you prefer a more intense taste, you can always mix it with your preferred milk. However, if you’re going for a milder, more neutral taste, you might find this protein powder to be a bit too sweet. Again, this would depend on your personal preferences.

I’ve also tried the Strawberries and cream flavor and it pretty much tastes like a strawberry milkshake. I wanted to amp it up for a creamier flavor. I ended up mixing it with milk and it was simply delicious. 

When it comes to mixability, it’s remarkably smooth and works well with water and milk alike. It’s best mixed with a shaker and a blender, though.

Pros and Cons

Looking back into the points made in this Isopure Zero Carb protein powder review, here are the key points to consider if you’re looking to this supplement as your next purchase to boost your protein intake. 


  • The use of whey isolate as a premium protein source offers so many opportunities to improve nutrition whether you’re a bodybuilder, a weightlifter, an endurance athlete, or a fitness enthusiast. Being immensely low in carbs and fats plus with the presence of essential amino acids, you’re bound to attain optimal results when it comes to muscle building and strength. Whey protein isolate is also digested quickly, making it an ideal option to use before or after your workout. 
  • The addition of multivitamins (and at a good dosage) also makes the Isopure Zero Carb a fantastic drink if you’re looking to boost your immune system as you stay in shape and build some lean muscle. 
  • Its glutamine content makes the Isopure Zero Carb a good alternative for people who are cutting down. When you want to get rid of body fat but don’t want to end up losing muscle, glutamine will see to it that your body still achieves optimal performance.
  • The Isopure Zero Carb comes with a strong, sweet taste that will please your taste buds. It also mixes well when you use a shaker or a blender, and can be incorporated into diet-friendly recipes.
  • If you’re keeping your diet as clean and nutritious as possible while avoiding lactose and gluten, you may want to try the Zero Carb.
  • For the most part, this product offers incredible value for money, thanks to its adequate dosage and wide range of nutrients available. It doesn’t come with proprietary blends so every component is simply clear and transparent.  


  • The Isopure Zero Carb doesn’t come with digestive enzymes, which may be an issue if you’re highly sensitive. Still, we’re speaking of whey protein isolates which are pretty easy to digest, so this product won’t always cause digestive issues.

My Final Thoughts

So it’s time to wrap up my Isopure Zero Carb Protein Powder Review. If you often rely on protein powders to increase your protein intake, then you should certainly invest in a superior product like this one. 

Overall, I’ve long been impressed with this supplement. It’s truly a great value for your money. If you’re looking to limit your carb intake without having to sacrifice nutrition, you’ll get a kick out of this topnotch Isopure product.

Its advantages certainly outweigh the possible issues that may arise. This Isopure Zero Carb protein powder is highly commendable when it comes to supporting muscle building, meeting daily protein needs, and aiding in muscle health.

If you require over 50 grams of protein per day based on your nutritional needs and physical activity, you can still increase the servings. But you must discuss this with your trainer or a physician to achieve the safest, best results.

The flavors are also spot-on; although I’ve only tried a few, they’re all pretty darn good. It makes working out a fun thing to look forward, too. For me, it does not disappoint and I recommend it as one of the better clean-and-lean protein supplements in the market today.
