Naked Diet Whey Isolate 97

Naked Diet Whey Isolate 97 is made with premium grade whey protein isolate containing 97% pure protein and also includes natural flavours, colours and Stevia sweetener. It undergoes a unique microfiltration and ultrafiltration manufacturing process which produces an ultra pure whey protein isolate which is very low in fats, carbs and calories. This makes it ideal for anyone looking to reduce their calorie intake and achieve their diet goals.


Naked Diet Whey Isolate 97 - Ultimate Purity

The purity of Naked Diet Whey Isolate 97 can be directly attributed to the unique manufacturing process it undergoes. This is because Naked Diet Whey Isolate 97 protein is extracted from whey which is from cheese manufacturing and uses membrane technology at low temperatures through two processes known as microfiltration and ultrafiltration. This ultimately produces a very pure form of whey protein that's had its lactose, carbohydrates and casein removed. This leaves ultra-pure whey protein isolate.


Naked Diet Whey Isolate 97 - 100% Natural

Naked Diet Whey Isolate 97 is made with the sweetener Stevia Extract and natural flavours giving it a more subtle taste and texture. This is ideal for anyone looking for a protein shake without any artificial sweeteners, colours or flavours. It is also quite often preferred by people who don’t like their shakes too sweet. This is because Stevia Extract in the form of Steviol Glycosides has zero calories, zero carbs and a zero glycemic index (GI). It is derived from the sweet leaf plant native to South America. Also, because Stevia Extract is so low in nutritional "nasties", it works extremely well with the low-carb, low GI nature of the whey isolate to produce a very lean protein shake.

Am a total newbie to protein shakes, so I guess I can't base this review on other products. However, one of the main reasons I haven't been down this route recently is due to past experiences many years ago...yes I am not a fledgling! I was concerned that it would taste artificial and therefore be unsustainable for me. I ordered the Cookies n Cream flavour as well as the Vanilla. I tried the Cookie one first with drinking coconut milk, i.e. not full fat, and was seriously impressed so much so I now look forward to my daily shakes. I subsequently have tried both flavours mixed in smoothies as well as stand alone shakes and have used almond milk as well as coconut milk. Am completely converted. Thank you Protein Works for your superb product.

Excellent product

Have used many brands in the past and often struggled to find something low carb, without nasty artificial ingredients and that tastes nice. So tried the Vanilla creme flavour and WOW what a great product! I was concerned the stevia taste would come through but can truthfully say this tastes delicious. Clumps a bit so a blender works best. Great in almond milk, porridge, yoghurt... Definitely buying more!
