Product Information



50 grams of 100% pure whey protein isolate and not a carb in sight. And it still comes with glutamine and nutrients, but no lactose or impurities, so it’s easy to drink. Your gut will agree.

That’s what we’re made of. It’s also what we stand for—protein that’s lactose-free, low calorie, with little or no fat and carbs, and no impurities. The purest stuff out there. Not to mention delicious. Beyond quality. This is protein with taste.
Pack in powerfully pure protein, without packing on the carbs. Our 100% whey protein isolate powders amp you up, without any unwanted weight. Just pick your level: Zero Carb or Low-Carb (which also has ZERO sugar), both with 25 grams of protein per scoop. It's 100% whey protein isolate loaded with vitamins, minerals and nutrients to keep you going strong—and always without gluten, lactose, or any impurities. Made with our complete microfiltration process to be the only completely clear milk protein when dissolved in water. Available in a range of delicious flavors to mix up some seriously delicious and dynamic recipes. Note: Zero/Low Carb Isopure powders have a vitamin/mineral premix which is not soluble; they will be cloudy when dissolved.

Good choice
The powder taste pretty good. The taste is better than most powders I have tried. It is however, caulk like and lumpy in my shake. It did help to blend the powder prior to adding fluid.

Good protein
Like the taste and the fact it is carb free. The only reason I didn't give it 5 stars, was because it doesn't mix completely. There is still some undissolved protein left when I drink it. Other than that, it is a good product.

Great for low-carbers!!!!
I was looking for a protein supplement and found this in GNC. I was (at the time) pre-diabetic, so the carb factor of most shakes were to high. This one is perfect! I tested my glucose level after consuming, and there wasn't a spike at all. I was also on a weight loss journey but DID NOT use this as a meal replacement. It did not have a negative effect on weight loss as I added this to my regular meal plan. I just included this in my daily calorie goal as a snack. I LOVE the cookies and cream flavor!

What protein powder should i buy that will not affect my gout and arthritis?
A shopper on May 28, 2013
BEST ANSWER: I would recommend Nature's Best Perfect Zero Carb Isopure as the protein powder least likely to cause issues with your gout and arthritis.
do all isopure products contain soy?
A shopper on Feb 25, 2018
BEST ANSWER: Yes; however, Soy Lecithin is a natural and necessary emulsifying substance found in the cells of all living organisms. It is found in many whole foods such as cabbage, cauliflower, chickpeas, nuts, seeds, and eggs among many others. When this seemingly innocuous additive is listed on a food label, it is usually one of the very last ingredients. This means that minute amounts are present.
When you use the word instantized. Is that the same meaning as hydrolyzed and micronized? In other words does the isopure protein instantly reach your muscles or does it take up to 25 min?
A shopper on Jul 21, 2013
BEST ANSWER: The word instantized means to make (foods or other products) available in instant or easily prepared form. It is not the same as hydrolyzed (reacts with water) or micronized (reducing diameter). The protein in this is pure, all impurities have been removed. It enables it to process faster, but not instantly.
Cna this be taken twice a day? or it has to be extrictly as directed?
A shopper on Feb 17, 2013
BEST ANSWER: Instructions on all vitamins and supplements should be followed exactly, unless directed by a physician or other health care provider.
Hi, can I take this product before and after workouts or it has to be once a day as the directions say?
A shopper on Feb 16, 2013

You should consult your physician and request to have your levels checked to make sure you are not deficient or getting too much of these properties in your body.

Is this product gluten free?
A shopper on Sep 15, 2012
BEST ANSWER: Yes, this product is Gluten free. It does contain the L-Glutamine, which is commonly confused with Gluten because of the similarity of the names. However, L-Glutamine is an amino acid that our bodies naturally produce, whereas Gluten is not.
I don't see any reference to Gluten Free; however, there aren't any "wheat" ingredients listed on the label?
A shopper on Jul 21, 2012
BEST ANSWER: The FDA is still developing a standard for which foods and dietary supplements may be labeled as gluten-free. This should be in place by the end of 2012. While there is some uncertainty about required standards companies may be wary about labeling something as gluten-free, to avoid later recalls.

Can i drink ISOPURE Zero carbs with MEGA MAN ?????
A shopper on Jun 11, 2012
BEST ANSWER: Yes you can drink ISOPURE Zero carbohydrates with MEGA MAN. However, the mega man would ruin the zero carbohydrates of the Isopure and you would end up in taking carbs. If the zero carb thing doesn't matter for you then go ahead!

A shopper on Jan 20, 2010
