About This Product

Isopure Zero Carb Protein Powder - Creamy Vanilla

  • Zero Carbs
  • 50g of Protein from 100% Whey Protein Isolate

♦ Nature's Best Perfect Zero Carb Isopure ® contains 50 grams of 100% Whey Protein Isolate. Any and all impurities typically found in most whey proteins have been removed to provide you with a great tasting, lactose free, glutamine enriched, state of the art carbohydrate free protein supplement.

♦ Nature's Best set out to create a product that didn't hide anything from its customers. We wanted you to know that you're purchasing the best product available on the market. Our protein source is clearly identified as 100% Whey Protein Isolate. We didn't try to confuse you by listing a protein blend that doesn't tell you how much of the product is superior whey protein isolate and how much is whey protein concentrate or sweet whey or some other inferior protein source.

♦ Furthermore, ISOPURE contains 0 g of sugar and is instantized so it can be taken anywhere and mixed with a spoon.


♦ Isopure's Major Proteins include:

  • Beta-lactoglobulin 55-62%
  • Alpha-lactalbumin 19-22%
  • Immunoglobulin 9-10%
  • Bovine Serum Albimin 6-8%
  • Lactoferrin .5-1%

♦ In addition, Isopure is rich in branched chain amino acids and glutamine. Each serving of Isopure Contains:

  • 3465 mg of isoleucine
  • 7865 mg of leucine
  • 3080 mg of valine
  • 4.6 g of L-Glutamine.

♦ Athletes tend to need more protein than sedentary individuals to achieve positive nitrogen balance. Most recommendations range from 1.5 - 2.0 grams of protein per kilogram of body weight per day. Isopure will help you achieve the positive nitrogen state you are seeking.

♦ It's So Pure The Protein Dissolves Clear. In addition to dissolving clear, Isopure protein is also light and easy to drink. The protein used in Perfect Isopure doesn't have the properties typically associated with a milk protein. It doesn't look, smell or taste like milk. We isolated the whey protein molecules and eliminated the impurities to provide you with the purest product of its kind.

♦ You'll note when you mix Isopure powder the results are cloudy. This is due to the addition of valuable vitamins, minerals and flavorings. However, the proof is in our 20 oz ready-to-drink Zero Carb Isopure bottles. Please check out our selection of assorted flavors. The protein dissolves so clear you can see right through the bottle.

Directions

For a rich, thick shake, mix 31g (about 1 scoop) with 6-8 fl oz of water in a shaker or blender. If a shaker or a blender is not convenient, Isopure Zero Carb can be stirred into solution with a spoon.

Item not as described
I ordered the advertised gray bottles of ice, pure vanilla, whey, protein, and received white bottles. This is a different packaging with different nutritional values. Very disappointed.

Formula Change is Terrible
The recent formula change has ruined this product. I couldn't get past how awful the powder smelled to even try to taste it. I've found other reviews mentioning the same so I'm on the hunt for a new protein powder.

This has been my go-to protein for over a decade.Just picked up a new canister and it's white.Asked staff about changes and they said it's just the outside remarketing.NO!This is a true change in product and now taste horrible. Will return and start looking for a different brand. I'll never understand why companies mess with what has worked for years.

Be aware if you order off this site, could be your fault if they send you the wrong one
You are taking a major risk ordering this for delivery from this site. Not only are you subject to them just sending you anything, when they send you the wrong flavor, instead of owning it and correcting it, then put the work on the people who made the purchase

Horrible taste
Absolutely disgusting. It tastes like you're chemicals. I've been drinking protein powder for decades this is by far the worst I've ever had. If it didn't have sucralose I'd understand, but it does. I had no idea how this has good reviews.

Well worth it!
Great flavor. I mix it with milk and put it in my nutrí bullet blender with some blueberries and it's fantastic. Has really made me feel better after my workouts. Prior to taking this I wasn't recovering but after purchasing this protein powder I feel great. Well worth the money.

The Dietary Benefit of Iso Pure Protein Powder.
Iso Pure Protein Powder is a tasty ingredient for Smoothies, adding 25 grams of protein, zero carbs, & zero added sugars per serving. It mixes well with frozen fruit & greens in a blender, producing a healthy breakfast or snack. I would recommend it to anyone adhering to high protein, low carbohydrate diet.

Flavor is great

Judith S

Wanted

Michelle C

Best taste and have been using for over 3 years

Judith S

Tastes good easy to drink

BOB M
Is this safe to use for young women (18 years)?
Vivienne S

Best Answer:  Sure, would recommend it to any person male/female wanting to add protein to their diet. Is easy to drink and mixes well with anything.

Danny W
How does the taste of this product fair against other companies, or in general how is the taste?
A shopper

Best Answer:  Not sure how all the flavors are but I can say that the creamy vanilla doesn't taste good. I thought it would just be a regular vanilla flavored but turns out Its not. I would reccomend getting a different flavor than creamy vanilla.

Paul B
I will be using this more as a breakfast replacement. Will this cause weight gain if I'm NOT working out regularly?
shawn g.

Best Answer:  No. One of the main reasons I chose this product is because it has 0 Carbs/0 Sugar and very low calories. If you take two spoonfuls, you're only getting 200 or so calories (and again, none from carbs/sugar).

I use this as a breakfast replacement by blending 2 cups of water, a scoop of nonfat greek yogurt, a scoop of the protein powder, and a cup of blackberries/rasberries...it's a great meal replacement, low in carbs, sugar, and calories...plus you get the protein to carry you through the morning. You could even add some almond butter if you wanted to boost the calories/protein intake.

Ross F
Can you mix it with milk snd how does that change the makeup?
richard k

Best Answer:  You can definitely use milk. It will only add the nutrient factors of the milk to the nutrients of Isopure's protein powder. So it increases the calories and all the other nutrients when combined. I use unsweetened almond milk with my Isopure prrotein shake. And I also add fresh fruit, spinach and/or natural peanut butter to my shake as well. The combination profiles are endless.

Gus C
I was told this can help with weight lose. To drink a shake in the morning and when for lunch, then a sensible meal for dinner. is that true?
A shopper

Best Answer:  I wouldn't rely solely on any whey protein, but I do use this religiously and notice the effects on body composition. Depending on my goals I mix 25g (one scoop) with 8oz skim milk, or 50g with water. But I only do this in between solid meals to keep the protein high. Makes a difference.

Ernest
Is this FDA approved?
Julie Sines

Best Answer:  It doesn't say on the packaging. I looked at all my other supplements and vitamins and none of them have it either. I would have to refer you to their website The Isopure Company.

Sara H
Does this Product contain any Soy, Soy lecithin, or Egg? Im allergic to both and am trying to find a product that does not contain any of it. Thanks!
Jose C

Best Answer:  Those ingredients are not listed on the container, but there is a note that says, "This product is produced in a facility with soy, dairy, egg and wheat ingredients, peanuts and tree nuts."

TERESA
Can we use it as a prework out?
A shopper

Best Answer:  Yes, of course. YOu are supplying protien before your work out. This is OK. But if you work out in the a. m. you may want to wait until after workout.

patricia h
Does this product actually list "gluten free" on the label?
Rachel M

Best Answer:  Yes

pamela l
do you really gain weight with this product?
A shopper

Best Answer:  We use this in our morning shake everyday, 1 scoop, 1/2 daily amount. It still all depends on your body type and rest of your diet. I don't gain muscle or weight easily and haven't gained any. My partner bulks up easily and was gaining weight so stopped adding to his shakes.
Hope this helps. DON

Questions for Similar Products
My question is regarding the supplement facts. When it gets down to the listing of vitamins, it has 0 listed under amount per serving for every vitamin and I didn't understand this if it's supposed to contain so many vitamins. Can you please explain? Thanks for your input.

I have been trying to get the answer to the following question by phone calls to custom service. I got called back several times; but each time the caller said he needed more time to dig out the information. Why is it so hard to get this simple answer? Is Vitamin Shoppe uncomfortable to answer this question?

What is the source of these amino acids?
The bottle used to say they are from Ajinomoto, a Japanese company.
But the bottle does not say that anymore.
Where are the amino acids made now?
Thanks!
