ALDI out-flexes the competition for protein supplement ratings

When it comes to hitting the gym and working out, what you put into your body could have more of an impact than how much weight you’re throwing around, or how many kilometres you’re running on the treadmill. But as many of us know, it can be tough to eat healthily, with plenty of fast-food options and office snacks lying in wait to undo all your hard work. In addition, understanding nutrition can be a tricky business, with finding the right balance enough to frustrate even fitness professionals.

Regardless of how familiar you are with the fitness industry, most will know that protein is often the key to getting your dream body, with the macronutrient playing a big role in building muscles and strength. And while foods including chicken and nuts can be easy to prepare, fitting in another meal isn’t always a viable option, particularly if you lead a busy life outside the gym. As a result, supplements have become a gym kit essential for many, whether it’s protein bars or powder for shakes.

While protein supplements can be convenient when you have one you like, finding the right brand in the first place is the tricky part, with the market bulging at the seams. That’s why Canstar Blue produces an annual review of protein supplements, to find out which are rated best by the people who use them.

This year, we surveyed over 1,200 Australian adults about the protein supplements they purchased and consumed in the last six months. Respondents rated their respective brands on important factors such as effectiveness, taste, texture, flavour variety, packaging appeal, value for money and overall satisfaction.

Our latest ratings saw supermarket ALDI rated best for protein supplements, receiving five stars for overall satisfaction and all other categories, knocking Bulk Nutrients off the top for the first time in three years.

Protein Supplement Buying Guide

With the protein supplement bulging at the seams, it can be a bit daunting for some who are looking to explore supplements and the world of fitness for the first time. To be a good gym buddy, we’ve broken down some of the major areas you should look into before scooping up your next protein shake.

In this guide, we’ll look at:

What do protein supplements do?

Man drinking protein shake

Protein supplements are essentially an easier, and more effective way, to get more protein into your diet. Protein is essential to helping your body function, keeping your muscles strong as well as increasing muscle mass, and is a key ingredient for anyone looking to get fitter, stronger or a mixture of both, (provided you put in the work).

As an artificial means of getting protein into your diet, protein supplements are able to supply higher intakes of protein than other foods, often without additional carbohydrates and fats. For example, a 31g serving of Optimal Nutrition 100% Whey (Vanilla) protein powder includes 24g of protein, 1g of fat and 4g of carbohydrates – which equals to 120 calories per serving. In comparison, a 100g serving of chicken breast will include 31g of protein, 3.6g of fats and 0g of carbohydrates, equating to a calorie intake of 165, according to the United States Department of Agriculture (USDA). To further put protein supplements into perspective, the USDA also outlines a 100g grilled rib eye steak includes 24g of protein, 22g of fats and 0g of carbohydrates, which is 291 calories per serving.

So when you add it up, Optimal Nutrition’s 100% Whey packs more of a protein punch (and less of a fats hit) than meat at a smaller serving size, meaning that it can be a useful option for those who don’t have time – or the stomach – for a full meal, or are looking for something that is full of protein without all the extras. While it may be hard to convince some to swap a juicy steak for a protein shake, if you’re looking to bump up your protein intake, it may be worth looking into.

Types of protein supplements

While a bodybuilder with a protein shake may be the first thing you think of when it comes to protein supplements, there are a number of options readily available for those looking to get a protein hit in, including ready-made drinks, protein bars as well as other snacks such as protein balls or other sweets. We asked our survey respondents what supplement type they last bought, with the results below:

  • Powdered (such as whey protein powder for shakes): 58%
  • Solid (such as protein bars or protein balls): 26%
  • Liquid (such as ready-made shakes and drinks): 13%

While we’d all have our preferences for how we get our protein fix, if you’re on the fence about which brand to pick up the next time you’re in need, check out our guides on protein powders and protein bars available, and which ones may be the best fit for your protein needs.

How much protein do I need?

Cropped image of handsome young sportsman

How much protein you should be having is a big topic of debate, with plenty of people weighing in with their opinions. At the end of the day, how much protein you should have in your diet will ultimately come down to how active your lifestyle is, what your body goals are, as well as a number of individual factors. So, while the big dog at your gym may recommend a certain amount of protein, if you’re only just starting out in the weights section, chances are you’ll need a different amount.

According to studies published within the CSIRO Protein Report, protein intakes vary depending on lifestyles, with 0.8g of protein per kilo of bodyweight recommended for those with sedentary lifestyles, while 1.6g per kilo is recommended for those with highly-active lifestyles, or those who require higher protein intakes. Similarly, if you’re looking to bulk up (i.e. put on muscle and body mass) then increasing your protein intake will be the first step.

If you’re not 100% sure about how much protein you should be adding to your meals, it’s always best to consult your GP or a medical professional before embarking on a new health kick.

Can you have too much protein?

Man eating steak

With protein playing an important role in building and maintaining muscle, the more you have the better, right? Potentially not. While many bodybuilders swear by high-protein intakes – and seemingly have the bodies to prove it – there is evidence, such as a study published by the Medicine National Institute of Health, that indicates high protein diets can put unnecessary pressure on the kidneys and liver, although another study published by the same institute, outlines that how much protein is too much protein will depend on the individual.

If you’re worried about how much protein you should be getting in your diet, it may be worth consulting with your GP, or a nutritional expert before beefing up your diet.

What’s Australia’s favourite protein flavour?

ctive people with sport nutrition

While most of your focus will be on whether or not your protein supplement works, swigging down something that doesn’t taste great makes getting your protein intake a lot harder than it needs to be. Thankfully, most brands offer a wide variety of flavours to entice you, with some sticking to the classic chocolate or vanilla flavours, while others are more adventurous with flavours, such as ‘birthday cake’ available as an after-gym treat.

But which flavour do Australians prefer? We asked our survey respondents what their favourite flavour of protein supplements is, with the classic flavours coming out on top:

  • Chocolate: 30%
  • Vanilla: 24%
  • Coffee: 7%
  • Strawberry: 7%
  • Banana: 6%
  • Caramel: 6%
  • Choc Mint: 6%
  • Cookies & Cream: 6%
  • Peanut Butter: 5%
  • Cheesecake: 2%
  • Birthday cake: 2%

How many calories are in protein?

Similar to carbs, protein has four calories per gram, while fat has nine calories per gram. That’s why you will have to keep an eye out for what your protein supplement is made of, because you don’t want to be filling up on something that doesn’t help you reach your body goal!

  • A typical 30g scoop of Whey Protein Isolate (WPI) has about 470kj (or about 110 to 120 calories)
  • A WPI 30g scoop should ideally have about 25g of protein and minimal sugars and fats

Whey Protein Concentrate (WPC) has slightly less protein content per 30g, but is a more densely-packed form of protein, allowing more powder per scoop. Other vegetarian and vegan-friendly proteins, such as pea or hemp proteins, are generally lower in protein content again, at around 15-20g per 30g scoop.

Similarly, protein bars can also vary, although are generally between 10-15g per 60g bar, although some have as much as 25g.

To get the best bang for your buck, your protein supplement should ideally have as much protein per serving as possible, while being low in carbs and fats, although this will also be dependent on what you want out of your protein supplement, as you may not mind having a few extra carbs to fuel a big gym session.

Does protein powder expire?

Athlete tasting new protein supplements

Getting to the gym on a consistent basis can be tough, especially when life gets busy. So, if you’ve missed the gym, is that tub of protein powder you bought ages ago still good to take? While it doesn’t expire or go off like other foods do, protein powder can lose its effectiveness over time in a process known as Maillard Browning, which is when protein reacts with left over sugar from when the Whey protein is extracted from milk.

The best way to tell if your protein powder has lost its edge is to taste test. So, if you’re triple choc protein powder tastes closer to cardboard than chocolate, it might be time to throw it out and stock up some new supplements. If you’re not willing to taste test, most supplements will also have an expiry date for you to keep an eye on.

What’s the best protein supplement for kids?

Being a kid can be a fun time, but with so many physical issues we encounter in adulthood beginning in childhood (such as back issues from not sitting up straight), it can be a time where we’d wish we starting taking care of our bodies earlier. But when it comes to building muscle, can you be too young to start?

The short answer is yes and no. While taking protein supplements as a child or teenager may help promote muscle growth, there may be a number of negative side-effects or long-term issues from doing so, as the teenage body is already going through multiple changes, growth spurts and chemical reactions, meaning adding protein supplements into the mix too early may interfere with some of the body’s natural progression.

Just like every adult, not every child or teenager will need a protein supplement to help promote health and fitness, although those who are heavily involved in sport may benefit from a supplement that focuses on recovery, with some brands offering a kids range of products that have smaller intakes of protein to help promote healthier eating habits and fitness programs. However, it’s always best to consult with a doctor or medical professional before your child starts taking a protein supplement, as you may end up doing more harm than good if their body hasn’t finished growing.

Which protein supplement should I use?

There’s a lot more to a protein supplement than simply how much protein it’s packing, with the levels of fat, carbs and ingredients also important to consider before you hand over your hard-earned money. In addition to taste and texture, factors such as price and even how easily you can get your hands on each particular brand will also influence which supplement you go with. And while the beast in your gym may recommend a certain brand, it may not be the best fit for you as you may have different body goals, as well as require different intake levels, meaning there isn’t a one-size-fits-all approach.

Ultimately, which protein type and supplement brand you choose will be your own personal decision, but researching what’s out there, and looking into the nutritional information of each product, can help ensure you see results you want before summer comes around.

Frequently asked questions

Canstar Blue surveyed more than 6,000 Australian adults across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics. The outcomes reported are the results from customers within the survey group who have purchased and consumed a protein supplement in the last six months (note: this includes protein shakes/powders/whey and protein bars/balls that are designed to supplement a regular diet, NOT be a meal replacement) – in this case, 1,236 people.

Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
