Premium Whey Protein Isolate (NZ Sourced)



Blended with NZ grass-fed whey protein isolate, natural flavourings and without unnecessary fillers, True Premium Whey Isolate is your first choice for lean muscle development and weight management.  Savour the clean taste, pure quality and high protein content that makes it easy to digest in shakes, smoothies or as a protein-boost in recipes.

Quality Matters

Leading manufacturing processes

Our whey protein isolate is manufactured through a combination of both cross flow micro-filtration (MF) and ultra-filtration (UF) to provide an extremely pure and refined protein.

Less than 1% carbs/sugar

The carbohydrateds and lactose that are present in normal whey protein are removed in an isolate protein, making it one of the purest proteins in our range.

High in protein

Whey protein isolate has one of the highest protein contents of any known substance to man. In natural form it boasts 90%+ protein content making it ideal for supporting lean muscle growth.

Fast digesting

The bioavailability of whey protein isolate means it is quickly digested by the body to provide essential amino acids for fuel or recovery.

New Zealand sourced

Not all protein powders are made equally, NZ proteins are considered the best in the world due to industry leading livestock processes and strict government regulations.

Rich amino acid profile

Whey protein isolate contains a complete amino acid profile for rebuilding muscle and providing vital nutrition for the body.

Premium Ingredients

NZ Grass Fed Whey

All NZ protein powders are grass fed due to strict government regulations. The mixability, taste and texture of NZ sourced whey is far superior to protein from other countries.

Natural Cocoa

Organic Dutch Cocoa is filled with natural flavonoids and antioxidants – surrounded by that rich chocolate taste.

Natural Chocolate Flavour

Sourced from a leading international supplier this natural chocolate extract delivers a sensational flavour boost.

Organic Stevia

Our Stevia is 100% organic, 100% natural and provides 150 times the sweetness of sugar. It also contains zero calories and has been linked to lowering blood pressure.

Xanthan Gum

A tiny amount of this remarkable stabilising agent delivers great mixability with no effect on colour or taste.

Whey Protein Smoothie

Suggested Use

Add 1 Large TP Scoop (30g) to 150ml-200ml of liquid of your choice. Shake and consume. Consume 1-3 servings daily or as required.

True Protein recommends as a guideline 1.5 to 2 grams of protein per kilogram of bodyweight. This recommendation is based on the assumption that your goals are to build lean muscle and enhance recovery. This translates to an 80kg person taking roughly 120g to 160g of protein per day. We recommend that you fulfil this quota through a combination of wholefoods and protein supplementation.


What are the differences between True Premium Whey Isolate and True Whey Protein?

These 2 protein powders share many similarities to the extent they both have rich amino acid profiles and high biological values (rapid releasing).  However there are few differences both in terms of nutritional profile and price,

The key difference between a whey protein isolate and a whey protein concentrate is that an isolate protein powder has a higher percentage of protein content (90% as opposed to 80%).  This allows you to reach your macronutrient goals more rapidly per serve and receive a more concentrated protein boost. True Premium Whey Isolate also has trace amounts of fat, lactose and carbohydrates making it a much purer protein boost than whey concentrate. This profile may be especially appealing to people who are on low carbohydrate and fat loss diets.

Thirdly there is significant price difference between the 2 proteins. The additional treatments that an isolate protein powder must go through means that the manufacturers cost is higher.  Generally you will be looking at a price around 50% more than a whey protein concentrate powder on quantity to quantity basis.

Why have you chosen New Zealand whey protein powder for True Whey Protein?

New Zealand protein is widely regarded as the best available in the market, and superior to Australian and North American equivalents. The livestock processes are of much higher standards and involve the cattle being exclusively grass fed and exempt from hormone use. Bottom line, this leads to a higher quality raw material with exceptional mixability and taste in the finished product.

How is True Premium Whey Isolate flavoured?

We have opted to use Stevia to sweeten our flavoured proteins. Stevia is derived naturally from a plant that originated in South America and is 600 times sweeter than sugar. We therefore only need very small quantities of this naturally produced sweetener to flavour large quantities of protein. Our in house development team has pushed the boundaries of natural flavouring to develop completely unique flavours that contain no artificial flavours or additives, whilst maintaining a fantastic natural taste.

Why is Polydextrose included in True Whey Protein flavoured protein powders?

Polydextrose is a form of soluble fiber that is widely used in the food industry.  Its nutritional profile contains only 1 kcal per gram (25% that of sugar) and, therefore is able to help reduce calories.

The main industry uses for polydextrose are as follows;

1. Replacement for sugar, starch and fat
2. Frequently used in low carb, sugar-free and diabetic cooking recipes. .
3. It is used as a stabiliser and thickening agent.

True Protein uses polydextrose in extremely small quantities (<1% / <0.3g per serve) exclusively as a stabiliser and thickening agent. Put simply it binds all of the great natural ingredients together into a smooth creamy blend that can be drunk easily and tastes great. A small ingredient but makes a huge impact on your experience with our protein shakes.

I purchased the sample pack which the kids fight over. Love the chocolate however I find its not thick enough.

True Protein Response
Hi Christine, thanks for taking the time to leave this review. I'd recommend trying out our Whey Protein Concentrate or Pro3 as they are much thicker than the Whey Protein Isolate.
