True Tip:

True Protein recommends as a guideline 1.5g to 2g 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.

The Science Behind True WPI 90

How Cross-Flow Microfiltration Produces a Purer Protein

Sherry Sui

Sherry Sui

Head of Product Innovation & Technical Affairs

Expert Reviewed

Not all protein powders are created equal. True WPI 90 is manufactured using Cross Flow Microfiltration (CFM), which is considered the gold standard approach to producing whey protein. Unlike harsher processing methods, CFM is a gentle, non-chemical filtration process consisting of two stages: ultrafiltration and microfiltration.

This method is superior to common alternatives like Ion Exchange because it preserves the bioavailability of the protein, essential amino acids, and Glycomacropeptide—promoting satiety and lean muscle development. By minimising lactose, fat, and carbohydrate content, this product delivers a high protein yield that is perfectly suited to everyone, including lactose-sensitive customers.

The result: a pure, highly refined, and fast-digesting protein—perfect for fuel or post-workout recovery.

    The best protein powder out there

    I must have tried close to 20 different protein powders before landing on WIP 90 Vanilla from true protein.

    It tastes and mixes better than all the others and I have it in my overnight oats every morning without fail.

    Not a heavy protein

    A great light protein powder. I find all other protein powders way too heavy, even when having them with water. This WPI protein is fantastic, tastes great, easy to drink, and so light plus a range of flavours for everyone.

    Even recently I have moved to having it with full cream milk and it is just still so considerably light compared to others.

FAQs
FAQs

FAQs

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. To get from pasture to packet, the milk is collected from New Zealand grass-fed dairy cows and is pasteurised. Enzymes are then added to encourage coagulation, during which curds will form. Whey, the liquid component of milk, gets separated from the curds and is filtered to remove most of the fat and lactose. It is micro-filtrated to become WPC 80 and goes through a second ultra-filtration process that removes further fat and lactose to make WPI 90, resulting in a more refined whey protein. The filtered liquid whey is then evaporated and dried to become a pure whey powder, which is how it arrives at the True Protein HQ on Sydney's Northern Beaches, where we blend it with all-natural ingredients and flavours and package it on site. All of our protein powders contain a complete amino acid profile including all nine essential amino acids.

What is the difference between True's Whey Protein Isolate (WPI 90) 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 WPI 90 goes through a further ultra-filtration process that strips away lactose and other elements to give a purer whey with a higher protein content of around 90%. Please see here for further information Isolate vs Concentrate Difference.

Why do I need protein powder?

Protein is an important macronutrient that can be found in a range of whole foods and supplements. Quite simply, we can't live healthily without it. Protein powder can be used to supplement a whole food diet in both men and women and there are many benefits in doing so. Taking protein powder allows you to conveniently increase your protein intake, which can help to boost athletic performance and enhance muscular recovery as well as assist with shredding or weight loss and supplement a low-protein diet. You can read more about the benefits of taking protein powder and what it is here The Ultimate Guide to Protein.

How is WPI 90 flavoured?

Our WPI 90 is flavoured using 100% natural ingredients to ensure a clean, authentic taste without any artificial additives. We develop our unique flavour profiles using real food sources, including freeze-dried fruits, natural cocoa, real vanilla, organic desiccated coconut, and Manuka honey. This allows us to maintain a fantastic natural taste while keeping our protein powders completely free from synthetic ingredients.

What are the benefits of WPI 90?

  • no fillers, nothing artificial, no bad aftertaste
  • Between 23g and 27g of protein per 30g serving depending on flavour

How many protein shakes should I have per day?

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 fulfill this quota through a combination of wholefoods and protein supplementation. To determine how many protein shakes you should ideally consume, you first need to assess your individual requirements and how much protein you are currently getting from whole food sources. One protein shake per day is usually adequate, or up to three servings per day as required.

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. See above for our guidelines on recommended daily protein intake. Our protein can also be used as an ingredient in both sweet and savoury recipes. Check out our long list of recipes here Recipes.

What does the 90% protein content refer to and why do some flavours contain less protein per serve?

90% protein content refers to the natural form of whey protein isolate as a raw material (not our Natural "flavour"). In our finished product of WPI 90, the protein content will vary depending on the input of any additional ingredients - such as natural flavours - which will slightly reduce the overall protein content. Natural flavour has the highest protein content at 89g per 100g, while the rest have a protein content ranging from 77g to 85g per 100g. Based on the nutritional information, you can make an informed choice on the protein supplement that suits you best.

Can I take protein powder when pregnant or breastfeeding?

Generally, incorporating one serve of WPI/WPC or Plant protein from a trusted brand like True Protein could be appropriate to meet dietary protein inadequacies during pregnancy or breastfeeding. If you are considering using a supplement you should discuss this with your Medical Doctor and/or Accredited Dietitian before proceeding. Please see here for more information. Pregnancy Supplements

Can I use WPI 90 as a meal replacement?

We always recommend a balanced wholefood diet before adding supplements. A balanced main meal made up of wholefoods should provide protein plus other ingredients like complex carbohydrates, fibre, vitamins and minerals. We recommend using a protein shake as a high protein snack in addition to your meals.

Will taking WPI 90 help me lose weight?

Whey protein powder can be used to supplement a healthy diet for weight loss. Creating an overall energy deficit through exercise and eating a good balance of whole food groups is key for anyone looking to lose weight – unfortunately protein shakes alone don't contain any magic weight loss remedies, sorry! Despite the various claims from other companies, these pills and powders don't exist! However, taking protein shakes alongside a healthy diet can aid weight loss. Protein shakes can help fend off food cravings as they keep you feeling full and satisfied for longer. With no added sugar, nothing artificial, no fillers and trace amounts of fat and carbs, WPI 90 is healthy for you and comes in at under 120 calories per shake when mixed with water.

Are samples available of this product?

We have individual samples as well as a 10-pack sample box available of our WPI 90.

Why have you chosen New Zealand-sourced whey for your protein powders?

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 a much higher standard 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.

Can I cook with WPI 90?

Yes! Our WPI 90 protein powder can be used in a range of raw/cold recipes including protein balls, chia puddings, in your morning oats, smoothies and much more. You can find plenty of recipe inspiration in our True Life hub here True Life Blog.

Can I add WPI 90 to hot drinks or warm oats?

We do not recommend adding our whey-based products straight into hot liquids as the powder may curdle. First mix the powder with room temperature water and then add to your hot beverage/oats.
