Review of Nature's Best Isopure Zero Carb

Send to Kindle

A review of the Nature's Best Isopure Zero Carb whey protein powder product. Is it the best? Is it cheap protein? It among the top 10 protein powders? The answer may surprise you.

Rating: 3.5 (out of 5)

Welcome to this review of the Nature’s Best Isopure Zero Carb protein product. Nature’s Best was launched in 1984 and offers many fitness health products. As you know, there are many whey protein powder or casein protein powders on the market today.

I’ve reviewed many of them in my ongoing research for content for this website. (You can read or scan the various protein powders I’ve reviewed so far here, if interested.)

The protein powder space is very crowded with many superb products in this category. It’s also highly lucrative and hence so many competitors. That competition is good, though, as it has caused many sports nutrition supplement makers to “up” their game and improve. The quality of whey protein powder or casein protein is substantially better now than it was even 10 years ago.

Isopure Zero Carb Product Features & Benefits

One distinguishing factor of the Nature’s Best company is that they do not have  NSF Certified for Sport registered GMP certification. This  is highly desirable and an indicator of high product quality, but they do not have this certification.”GMP” stands for “good manufacturing practices” and is sometimes is represented as “cGMP” or “current good manufacturing practices.”

In essence, its in-house manufacturing operation has not been registered under the NSF whey protein powderInternational, The Public Health and Safety Company, Good Manufacturing Practices (GMP) Program.

Why is this so important? Because it is an indicator of product quality as the raw materials are tested and validated as pure and free of contaminants. It also indicates strict manufacturing compliance with actual product creation. NSF for Sport GMP certification also confirms the non-inclusion of banned substances, which is especially important for professional athletes who look to bodybuilding supplements to augment their training regimes. Of course, amateur fitness enthusiasts and bodybuilders are concerned about it, too.

Does this mean this is an inferior product? No, not necessarily. It is not a positive, though.

Let’s talk about the nutritional profile of this product. The nutritional profile of the Isopure Zero Carb product is excellent.

It provides the following:

  • 210 calories per serving with 10 from fat
  • 50 grams of protein per serving (this is one of the highest on the market)

In addition, the percentage of the daily value of the following vitamins and minerals is 50%. They are: vitamin A, vitamin C, vitamin E, vitamin K, thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, biotin, pantothenic acid, phosphorous, iodine magnesium, zinc, selenium, copper, Beast Creature Creatinemanganese, chromium and molybdenum. Plus, it gives 20% of the daily value of chloride, 6% of iron and 70% for calcium.

What about the protein in it? The Isopure Zero Carb protein powder is made from  ion exchange whey (from cow’s milk) and protein isolate.

It’s a full figured protein powder; it is by no means a cheap protein supplement.

What About Flavors Available?

The Isopure Zero Carb product comes in many flavors, but the different sizes, i.e., 1 lb, 3 lbs., and 7.5 lbs don’t have uniformity of all flavors. Here are the flavors available per the size options:

What’s The Price of Isopure Zero Carb?

The pricing of the this protein varies depending on the outlet. My research has revealed the following price ranges you can see online and offline:

Does Isopure Zero Carb Have a Guarantee?

Like most supplement manufacturers, Nature’s Best does have a general product guarantee for all Product guaranteetheir products. However, they also defer to the retail outlet, whether online or offline, as to their guarantee.

It’s for this reason I recommend buying from Amazon. Amazon is well known for its sterling customer service. Amazon has won the ForeSee Experience Index, best customer service for nine years in a row.

They say, “For the ninth consecutive year, customers ranked Amazon #1 in customer satisfaction during the holiday shopping season according to the newly-released ForeSee Experience Index: US Retail Edition. For their study, customer experience analytics firm ForeSee collected more than 67,600 surveys between November 29, 2013, and December 17, 2013, asking consumers to rate their satisfaction with the top 100 retailers. ForeSee ranked Amazon highest in overall customer satisfaction in the survey with a score of 90—the highest ever recorded by the firm.”

In addition, they have an outstanding guarantee as well, which you can read about here.

Best Protein For Your Money
By Joel Flores on June 28, 2011
This is my favorite protein. It tastes great specially compared to a lot of other brands, just like previous reviews its not to sweet or overwhelming. I saw a review that said its hard to mix, most protein is hard to mix with a spoon and this is certainly not any easier or harder than any other shakes I have used. I recommend using a mixing glass which you can find on amazon for under 8 bucks, these mixing glasses typically have a mixing ball or some type of mixing mechanism that helps blend together your shake or other drinks when shaken. If you want to go a step further use a blender and add strawberries, bananas, ice, eggs, nuts or any other healthy add on for flavor or additional protein. I personally use a magic bullet or a blender when at home if I’m out at the gym I use a mixing glass. Remember protein is at its most effective when taken within 30 minutes of your workout, not before, but right after and when taken with glutamine pills which help your body break down and absorb protein.

The Best So Far
By M. Hernandez on March 11, 2012
After years of using an wide array of protein supplements I tried Isopure and never went back to Weider, Myoplex, GNC or any of the other supplements I’d tried. Few, if any, of these supplements are FDA regulated, (aside from certain safety standards {?}), leaving an opening for inflation of the stated amounts of nutrients the manufacturer(s) claim. That leaves a huge gray area in determining which brand fuels muscle growth “better”. The only way to tell is to try different ones over the course of months & years. Then there are other, less important, (at least to me), factors protein-scoops1like: how well it mixes, how it tastes, packaging, shelf life etc. This product has been, by far, the best no-carb protein mix for me. It costs twice what the cheap whey proteins cost but I don’t mind paying the price when I’ve seen much better results, taste and ease of use with the Isopure. I’ve tried all the flavors and like the Cookies & Cream or vanilla flavors as they’re more neutral and allow for some creativity by mixing this into, let’s say: pancake mix, skim-milk banana shakes, yogurt smoothies etc. Bottom line, it’s good stuff.

Great stuff!

I’ve enjoyed using the cookies & cream flavored protein powder. It doesn’t give me stomach cramps like other powdered supplements out in the market. Definitely will try other flavors, but I know I can always fall back on C&C and not be disappointed. Side notes: Putting a teaspoon of cocoa makes it into a delish chocolate cookie and cream delight. I’ve even experimented mixing 1/2 a can of organic pumpkin with a touch of cinnamon and nutmeg — YUM. The only downside is that you won’t want to mix any fruit with it. Gross.

Are there any customer complaints? Like with most protein powders, some dislike the taste of some of the flavors. This is a common complaint, though, for all protein powders. Overall, customers seem to like the product.

Pros?

  • It has many flavor options
  • Overall, it is a fine tasting protein powder
  • Many customers love it
  • It has no carbs
  • It has among the very highest protein amounts per serving of any protein powder on the market today
  • It comes in many size options

Cons?

  • It is not made in a GMP-compliant or certified facility
  • It’s not very well known
  • Some don’t like the fact that it has no carbs
  • Some don’t like what they perceive to be a high caloric count per serving

Where Can I Buy It?

Isopure Zero Carb ProteinYou can buy the product here, but you are free to choose. (You can also go the subheading on this page entitled, “What About Flavors Available” above to choose a specific flavor you are interested in.)

Conclusion? This is a fine product but it’s lack of GMP compliance is a big negative as most of its competition have NSF Certification for Sport, GMP compliance. Competitors like Optimum Nutrition, MusclePharm, and Dymatize have it. That said, other than that negative, it is a fine product with good taste and is producing desirable results.

I hope this review of the Nature’s Best Isopure Zero Carb protein product has been helpful to you.
