Why Is Mirrabooka Grass Fed Whey Protein The Best Protein?

It's what we put in and what we leave out that makes Mirrabooka Protein the best.
Mirrabooka Protein is pure, premium quality, single origin, 100% Australian grass fed whey protein. This is not a blend of lower quality proteins. Mirrabooka is pure and clean- it does not contain any filler ingredients or artificial additives. Just the cleanest, purest grass fed Australian Whey Protein.
  • All natural, no artificial additives 
  • Single origin grass fed Australian whey protein- not a blend of lower quality proteins
  • No filler ingredients- means more protein per serving, not cheap filler ingredients
  • Naturally flavoured -  sweetened 

Why Is Mirrabooka The Best Tasting Protein Powder?

Our natural whey protein is deliciously smooth and creamy, and it mixes well in water.
  • Dissolves and mixes well -  shake it up with water
  • Smooth texture - not grainy or gritty, no powdery residue
  • Naturally creamy and slightly sweet - not bland and tasteless
  • Lightly flavoured and sweetened- not unpalatable

The Best Protein For Women

Getting enough dietary protein is essential for women's health. You need the most bio-available, fast digesting, low carb, clean ingredient, natural protein powder that tastes great so you can drink it at any time of day.
  • Promotes satiety- keeps you feeling fuller for longer between meals
  • Assists with weight loss- consuming higher levels of protein can assist you reducing total calories
  • Maintains lean muscle- fuels and maintains your lean muscle mass
  • Gluten free and low carb 

Why Is Mirrabooka Whey Protein The Best Protein For Men?

You need a fast digesting, great tasting, pure, clean and natural, complete protein to ensure you meet your daily protein intake requirements, to develop lean muscle, recover from sport and exercise, and maintain your immune system. You don't want filler ingredients and slow-release, low quality protein sources.
  • Complete protein - naturally contains all 9 essential amino acids needed for optimal health.
  • Naturally high in BCAAs - contains 4.5g of Branched Chain Amino Acids leucine, isoleucine, and valine which switch on your body's muscle building process
  • Fast digesting and bio-available protein - you absorb the protein quickly when you need it (pre and post exercise) and get maximum nutrition from each serving

Single Origin Whey Protein

Whey protein blends contain a mixture of lower quality protein sources to reduce production costs. Protein origin matters because climate, farming practices, processing and other factors affect the quality, taste and bio-availability of the final product. 
Mirrabooka Protein is made from a single source of premium Australian whey protein concentrate. What makes Australian dairy so good? It comes from Australia's South East region- predominantly Victoria, South Australia and Tasmania. This region has the ideal climate for year round pasture grazing, adequate sunshine and rainfall, good soil and pasture growth and excellent animal health. This results in less need for fertilisers and feed crops, and year round supply of grass fed cows milk, so you get the purest and best quality protein in every serving.

Ultrafiltered Whey Protein Concentrate

Ultrafiltered whey protein concentrate has undergone the least and most gentle processing of any whey protein, preserving a broader range of nutritional benefits (assisting lean muscle growth, weight loss and supporting your immune system), bio-availability and maintaining better taste than whey protein isolate.
Our ultrafiltered whey protein concentrate is Australian made from farm to packaging 
(cocoa, vanilla and stevia are not grown in Australia and must be imported).

Undenatured Whey Protein

Carefully sourced, processed and handled to prevent the protein and fragile protein fractions breaking down during processing and handling (denaturing). This preserves the protein structure and bio-availability, so that the beneficial macro and micro nutrients are broken down and absorbed in your digestive system.

Cold Processed Whey Protein

Whey protein is susceptible to damage from heat during the the entire process from farm to packaging. Mirrabooka Protein is low temperature processed and not exposed to prolonged high temperatures that damage the micro and macro nutrients, during the the entire process from farm to packaging. This preserves the nutritional quality and bio-availability.

No Artificial Additives

Many off the shelf protein powders contain a long list of artificial ingredients including synthesised vitamins, artificial flavours and artificial sweeteners (Sucralose). Artificial additives are highly potent and cheap to use- however they are not recognised by the human body as food, and may lead to long term weight gain, health problems and disease.
Mirrabooka Protein only contains the minimum number of necessary ingredients from natural sources. 

No Filler Ingredients

Mirrabooka Protein does not contain any filler ingredients such as maltodextrin, milk powder, skim milk powder, coconut flour, psyllium, sugar or fibre (inulin etc). 
These ingredients are used in many mass produced protein powders to bulk the product, reduce production costs and sweeten the product - at the expense of your health and nutrition. Those products are carefully formulated to maintain the protein source as the primary (first) ingredient- whilst the protein content per 100g is very low.
