Best Whey Protein in Australia

Best Whey Protein in Australia

There will always be a valid reason to seek out the finest protein powder Australia offers, regardless of the fashions in nutrition. Digestion breaks down protein into critical amino acids still necessary for a healthy body and life. 

While protein deficiency may not be fatal, this condition may lead to severely poor physical health. Weakened skeleton, skin, and muscular tissue are just a few consequences of insufficient protein in your diet.

Therefore, it’s essential to complement your diet with one of Australia’s top protein powders for your health and general well-being. Whey protein is a common source of this beneficial substance since it speeds up muscle repair, enhances fat reduction, and benefits cardiovascular health. 

The finest whey protein supplements are available as a concentrate, isolate, hydrolysate, or combination. Most athletes have found these products beneficial in helping them in boosting their protein intake, which is necessary for building and repairing worn-out muscles. 

If you need the best whey protein in Australia, this piece is for you. Continue reading to find the top-rated protein supplements and how to choose them. 

Let’s get started! 

Best Whey Protein in Australia

Whey protein, a byproduct of cheese production, is popular because it contains all essential amino acids like Phenylalanine, Threonine, and Leucine. 

These nutrients have a huge role in the body, including: 

  • food breakdown 
  • Develop new bodily tissue and mend damaged tissues
  • Produce hormones as well as substances that are found in the brain (neurotransmitters)
  • Supply a source of energy
  • Keep your hair, skin, and nails in good condition
  • Develop your muscular strength
  • Strengthen the immune system
  • Keep your digestive system functioning normally

In addition to a good diet and moderate exercise, whey protein supplements are highly recommended. Here are the top choices to use in your next blended drink.


1. 180 Nutrition – Whey Isolate

Natural WPI from 180 Nutrition is a pure whey protein isolate free of gluten and soy.

How to Choose a Protein Powder

Here are some factors to consider when choosing a protein powder if you (or your customer) have concluded that it is the perfect choice for you.

Which protein is perfect for you?

Most of this comes down to personal choice. 

Consider considering dietary intolerances and allergies here in addition to ethical issues, such as how much you prefer an animal or plant source. 

Protein Quality

Many individuals place a premium on the purity of their protein sources. Complete vs incomplete proteins is a common topic of discussion when evaluating protein quality.

Amino acids, the building blocks of proteins, come in various colours. They may be arranged in several ways, each performing a specific function in the body.

Your body uses twenty different amino acids.

Seven of the amino acids are optional extras. Because your body naturally produces them, of course!

Four amino acids are also “conditionally essential,” meaning your body may sometimes produce them. Sometimes the body has trouble making them, such as when you’re unwell or after strenuous exercise.

Essential amino acids are the other nine amino acids. You must receive them from food since your body doesn’t produce them.

This is significant since EAAs are essential for constructing muscle and other tissues and enzymes, hormones, and neurotransmitters.

Among the EAAs, BCAAs (branched-chain amino acids) are pivotal in muscle protein synthesis.

Muscle protein synthesis is how your body repairs and builds muscle after exercise. Among the BCAAs, leucine is the most well-known because it stimulates muscle protein synthesis.

Essential, branched-chain, conditionally-essential, and non-essential amino acids are all represented in this Venn diagram and a few more.

There are three types of amino acids: essential, conditionally essential, and nonessential.

Each of the nine EAAs is in enough quantity in a complete protein. One or more of the EAAs is absent or in inadequate amounts in incomplete proteins.

Plant-Based Vs. Animal Protein

Animal protein options can be divided into milk-based and other animal protein sources.

Milk-Based Protein Powders

Milk-based protein powders have dominated the market and have been the subject of much research. They are all high-quality protein options.

Whey is a popular choice for post-workout smoothies because of its high-quality protein, rapid absorption rate, and abundance of branched-chain amino acids (BCAAs). Whey protein comes in various forms: concentrated, isolated, and hydrolysed.

Due to its slower digestion rate, casein protein powder is often recommended as a bedtime snack. The two most common types are micellar casein (an isolate) and hydrolysed casein. Choosing a slow-digesting protein is somewhat undermined because hydrolysed casein is more processed and, in theory, digests quicker.

Milk protein blends often include whey and casein and are advertised as the “best of both worlds.” This is because they prthatrotein in both rapid and gradual release forms.

They are often labelled as milk protein concentration or milk protein isolate. Whey protein isolate and micellar casein are two examples of these that might be found in a more granular format.

Certain brands provide combinations of concentrate and isolate of the same protein type. For instance, whey concentrate and whey isolate may be listed as ingredients.

While the manufacturer may spin this as a perk, it’s a way to save costs. (The manufacturing cost of whey isolate is higher than whey concentrate.) There is no evidence to suggest this formulation is helpful.

For those trying to decide between whey and casein: Choose the one that appeals to you most, or combine them. 

Both have received much research and are, therefore, safe bets. Once again, the most crucial factor is the overall amount of protein you consume daily. Most individuals won’t be affected significantly by little variations in digestion and absorption times.

If you have a dairy allergy, you shouldn’t consume any of them. If you’re lactose intolerant, you may be able to handle whey but not casein, or vice versa.

Other Animal Protein Powders

There are several alternatives to dairy-based protein powders for individuals who are allergic to or don’t like them.

If you’re looking for a complete protein that doesn’t include milk, egg white protein is a fantastic alternative.

Collagen is widely used for its beneficial effects on the skin, joints, bones, and the digestive system. Most collagen supplements use collagen peptides, which come from either cowhide or fish scales. Some individuals use collagen powder as a protein supplement to increase their daily protein consumption.

This is amusing, given that collagen wasn’t entirely accepted as anything but a “junk” protein until the early 2010s. This is due in part to collagen’s incomplete protein profile.12 As a protein supplement, it has yet to be well researched.

Collagen could have valuable properties. For instance, type II collagen combined with vitamin C may benefit joint health.13 However, there are other optimal protein sources. Heavy metal contamination is a worry, and quality varies widely. Finding solutions that an impartial person has verified is thus essential.

Powders made from animal protein sources, such as beef, often have an amino acid composition with collagen. This indicates that they are often of inferior quality and are missing critical amino acids. However, contrary to popular belief, beef isolated protein is just as efficient as whey protein powders in boosting lean body mass.14,15 However, additional study is required.

Protein from tendons, bones, and ligaments is extracted during high-pressure heating to make bone broth. The liquid is dried and powdered. Collagen provides most of the protein in bone broth.

If you have trouble digesting prevalent allergens like lactose and soy, bone broth powder might be an excellent alternative to help you meet your daily protein needs. The protein included in bone broth is somewhat costly, and its potential as a dietary supplement has yet to be well investigated; thus, it is not widely used.

Plant-Based Protein Powders

Complete proteins can’t always be found in plant sources. You will learn which ones are full and missing, but before you do, a gentle reminder: if you consume various protein sources, you will get all essential amino acids.

As a complete protein, soy protein may help you build muscle and see results. Supplementing soy protein has increased strength and lean body mass in response to resistance exercise, similar to whey protein.16

Concerns about its effect on hormone balance have also sparked debate. On the other hand, soy meals and isoflavone (bioactive substances found in soy) supplements have been shown to have no impact on testosterone levels in males.17

Soy additionally has been shown not to enhance a woman’s chance of developing breast cancer.18 Also, soy seems to have no negative impact on thyroid function; however, further study is required in this area.

The fact that soy is an allergy for many people might also influence your choice.

Pea protein is low in allergens, easy to digest, and cheap. Lysine, glutamine, and arginine are three amino acids. It lacks the essential amino acid methionine.

Another low-allergen protein option that won’t break the bank is rice protein. It’s not a complete protein since it lacks the essential amino acid lysine.20

The hemp seeds used to create hemp protein powder are a fantastic whole-food option. It’s a good source of omega-3 fats and fibre. Unlike rice protein, hemp protein is incomplete because of its low lysine content.

Plant-based protein powders often come in mixes. Since diverse protein sources have varying concentrations of each amino acid, they are often combined to provide a complete amino acid profile. It’s common practice, for instance, to mix rice protein with pea protein.

Processing Methods and Quality

Concentrates, hydrolysates and isolates are just a few examples of the many forms that protein powders may take on.

What follows is a detailed examination of each processing option.

Concentrates: protein extracted from foods using high heat, acid, or enzymes, from either animals or plants. Concentrates range from 35-80% peptide by mass and undergo the fewest processing steps.21 The typical protein content is between 70% and 80% (although plant proteins, in particular, might be lower).

Carbohydrates and lipids account for the remaining fraction. The extra calories from faux-protein sources in protein concentrate may be acceptable for certain people.

Protein isolates provide at least 90% protein by weight because they undergo an extra filtering procedure that removes fat and carbs. This makes them somewhat easier to digest, but no proof exists that this aids in healing, muscle gain, or fat reduction.

Isolates may be a better option than concentrates for people watching their fat and carbohydrate consumption closely or for those ready to spend a little more for the promise of some additional benefit that may or may not materialise.

More processing eliminates most lactose from casein, whey,  and milk protein isolates; thus, they may be healthier for persons with lactose sensitivity.

Hydrolysates derived from proteins are made by further processing the protein with enzymes, heat, or acid to cleave the protein chains into smaller peptides further.

Protein hydrolysates are already quite simple to digest and absorb, but this additional processing and the ensuing shorter chains should make things considerably more straightforward. Protein drinks are popular among those who want to build muscle and are hence targeted at this demographic.

While this procedure makes sense, there must be more proof that hydrolysates are superior to isolates for this application.

Hydrolysates, on he other hand, might be gentler on the GI tract for specific individuals since they are practically pre-digested owing to their processing and contain even less lactose.

Hydrolysates, however, do have a few drawbacks. To begin with, they often have a harsh flavour that a lot of sugar or other sweets are needed to cover up.

Second, the bioactive micro fractions that aid digestion, mood, and immunological function remain in whey protein and “non-ionized” isolates. These bioactive micro fractions are absent in whey hydrolysates (and “ionised isolates”). 

Hydrolysates’ cost might be an issue if you’re on a tight budget. Protein powders tend to increase in price as they undergo additional processing.

Intolerances and Sensitivities

Protein powders containing components you are allergic to or intolerant of should be avoided. For instance, a plant-based protein powder may be your best option if you can’t consume eggs or dairy.

Isolates and hydrolysates are two examples of process solutions that may be better for those with stomach problems.

It’s also not unusual for tummy trouble to follow the introduction of a new protein powder. There are several possible causes for this. To find out what’s going on, use this handy checklist.

  • Substances: You may be allergic to some of the substances in the protein powder you’ve selected, or it may have undergone unfavourable processing. Checking the ingredient label is a good idea because of this. Before you locate the ideal protein powder, you should experiment with a few different brands.
  • Dietary habits: Other foods you may have had that day may impact how your body responds to a protein powder. For instance, many individuals have a threshold for how much lactose they can take before developing symptoms. You could be going too far if your protein powder includes lactose.
  • Quantity: This could be a problem. Sometimes it’s recommended for men to utilise two scoops of protein powder rather than just one. This can be too much for some people’s digestive systems to process at once. Others could create shakes with 1500 calories in an attempt to put on weight. Most individuals would find it difficult to process that. Therefore, experimenting with lower dosages may be helpful.
  • Speed: Sucking in too much air while drinking too quickly might induce stomach distress. Additionally, your GI tract requires time to metabolise a smoothie with several different components. You could find it simpler to digest if you move more slowly.


Several high-quality whey protein supplements are now available in Australia, and they may help you achieve your health and fitness objectives. Your nutritional goals, spending limit, and preferred taste all play a role in determining which whey protein is ideal for you. 

You should choose a high-quality product from a trusted brand, read labels thoroughly to be sure you’re receiving the appropriate macronutrient ratios, and avoid any ingredients you know to be allergies. Optimum Nutrition Gold Standard Whey, Dymatize ISO 100, and Myprotein Impact Whey Protein are some of Australia’s widely available and well-regarded alternatives. 

It may take some trial and error to determine which whey protein is ideal for you, but with so many possibilities in Australia, you’re sure to discover one that works.
