Description

With 50 Grams of Protein From 100% Whey Protein Isolate

Nature's Best® Perfect® Natural® 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 low carbohydrate protein supplement. Natural Isopure is sweetened naturally with cane sugar and has no artificial colors, flavors, preservatives or sweeteners. Natural Isopure also uses only all natural vitamins and minerals.

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% Pure 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, Natural Isopure is instantized so it can be taken anywhere and mixed with a spoon.



100% WHEY PROTEIN ISOLATE
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.

Many options
Isopure Whey Protein Isolate allows me to add protein to many different foods. So far a couple of my favorites are unsweetened applesauce and sugar free pudding. I don’t notice a difference in flavor at all.

Exactly What I Wanted
I wanted a protein powder without flavor and especially without sweeteners. This is perfect! I blend it into smoothies and stir into cooked oatmeal. I can not taste it at all. I am very pleased to have found exactly what I wanted.

Is this product Lactose free?
A shopper on Oct 5, 2012

Can I use this in recipes for cooking ? Many protein supplements cannot tolerate exposure to heat. Is there one that is better for cooking ?
A shopper on Feb 8, 2013
BEST ANSWER: When cooking with a whey-based protein, you will normally not lose any protein, however some of the other nutrients will degrade with heat. If you just want protein, heat in cooking is not a problem (since denaturing occurs naturally in digestion anyway.)
The description says that it is flavoured with can sugar, However, there is no sugar listed in the ingredients and the label say it is 0g carbs. What I should believe now?
A shopper on Nov 18, 2012
BEST ANSWER: Per the FDA website, anything less than 0.5g of carbohydrates is rounded down to 0 grams.

A shopper on Oct 25, 2011
