First-class Protein

Blended with New Zealand grass-fed whey protein isolate, natural flavourings and without unnecessary fillers, True's 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

Leading Manufacturing Processes

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

Less Than 1% Carbs/Sugar

The carbohydrates and lactose that are present in whey protein concentrate 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.


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 equal. New Zealand 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 ideal for rebuilding muscle and providing vital nutrition for the body.

The pina colada flavour is amazing. Literally tastes like a pina colada, iced and on a summers day is the best

Nice change

Taste was great- however, not as strong in flavour as chocolate mint (my regular flavour). The flavour was as you would expect, and it tastes like real banana rather than that fake taste you sometimes get with banana flavoured things. Went well in my oats

What is whey protein powder?

Protein powder is essentially a concentrated source of protein derived from either an animal or plant source. Whey protein is a high-quality, complete protein naturally found in cows’ milk. Whey is separated as a by-product of cheesemaking, when enzymes are added to the milk to encourage coagulation, separating the liquid from the solids (curds). The liquid content (whey) is strained off and filtered to remove most of the fat and lactose. For WPC80, the liquid is micro-filtrated and for WPI90 it goes through a second ultra-filtration process that removes further fat and lactose resulting in a more refined whey. The filtered liquid is then evaporated and dried to become a pure whey powder, which is how it arrives at the True Protein HQ, where we blend it with all-natural flavours and package it on site.

What is the difference between True’s Whey Protein Isolate (WPI90) and Whey Protein Concentrate (WPC80)?

The key difference between the two whey protein powders is refinement. Both powders go through a micro-filtration process in their raw state, but WPI90 goes through a further ultra-filtration process that strips away more of the lactose and other elements to give a purer whey with a higher protein content of around 90%. Please see here https://www.trueprotein.com.au/isolate-concentrate-difference for further information.

Why should I get the WPI Sample instead of a bag?

- Find which product and flavour is right for you before committing to a large bag
- Great travel-size sachets for protein on the go
- Every sachet is 100% natural with no artificial flavours, fillers or additives
- Pre-measured single serves
- Sample packs available for each of our bestselling protein powders

How is WPI90 flavoured?

We have opted to use stevia to sweeten our flavoured proteins. Stevia is derived naturally from a plant grown in South America and is around 200-300 times sweeter than sugar. We therefore only need very small quantities of this naturally produced sweetener to flavour our protein powders. 

What are the health benefits of WPI90?

- 100% clean, all-natural protein powder – no fillers, nothing artificial, no bad aftertaste
- 25g protein per 30g serving
- True only use the best quality raw ingredients from around the globe, including New Zealand grass-fed whey
- Possesses minimum 90% protein content
- All supplements feature non-GMO and certified organic ingredients wherever possible
- A complete amino acid profile containing all nine essential amino acids
- Only trace amounts of lactose, entirely gluten-free and with no added sugar, making WPI90 suitable for sensitive stomachs
- Suitable for vegetarians
- WPI90 has one of the highest protein contents of any known substance
- Only trace fat and carbohydrates, perfectly suited for lean muscle gain and fat loss

Can I drink WPI90 if I’m lactose-intolerant?

There is only a trace amount of lactose in our WPI90 protein powder due to the ultra-filtration process it goes through to remove the lactose. You may be able to consume it if you are lactose intolerant or lactose sensitive but should seek advice from your doctor first if you are concerned.

Can I take whey protein without working out?

Yes, it is perfectly safe to drink whey protein without working out, especially if you have a low-protein diet or are recovering from illness. However, it is important to review your own individual requirements to avoid excess protein consumption. It’s also important not to replace whole food sources with protein shakes. Protein supplements should ideally be used alongside a healthy balanced diet.

When should I take my protein powder?

If using your protein alongside an exercise regime then we recommend enjoying a protein shake within an hour of finishing your workout to enhance recovery. Protein shakes can also be consumed at any time throughout the day, depending on your individual needs. The latest scientific research suggests that consumption of 1.2-1.6g of protein per kilogram of body weight per day is an appropriate protein target (1). For example, if your current weight is 80kg then your dietary protein requirements are between 96-128g per day. Our protein can also be used as an ingredient in both sweet and savoury recipes.

Is WPI90 suitable for taking on a ketogenic diet?

Yes, as WPI90 is so low in carbs (approx. 1.9g per 30g serve with water) it is suitable for taking when following the low-carbohydrate ketogenic diet.

Suggested Use

Pour 150-200ml liquid of your choice into a shaker. Add the contents of 1 True Sample Sachet (30g) into the shaker. Shake well and enjoy! Use 1-3 times daily or as required.
