2017 award for protein supplements

Most Satisfied Customers | Optimum Nutrition

Optimum Nutrition has topped Canstar Blue’s customer satisfaction ratings for protein supplements in Australia, rating five stars across all research categories, including taste, hunger satisfaction, variety, effectiveness, texture, value for money and overall satisfaction.

If you’ve been hitting the gym, or just wanting to lose weight or replace the odd meal, you might have considered buying a protein supplement. But where on earth do you start?! Jumping into the world of protein supplements can be mind boggling, and you would pretty much need a chemistry degree to fully understand all the different names, products and jargon. However, despite all of those confusing terms, at the end of the day, what you probably need a boost in is just good old protein.

You can get lots of protein from chicken, but that gets a bit dull after a while, and isn’t very convenient if you need your protein quickly. So if you want something that’s easy to wolf down to get a boost in your protein intake, while not tasting too badly, a protein supplement could be the way to go. Of course not all brands are made equal, and often protein supplements can be quite pricey, so it pays to get it right the first time, rather than have a tub of protein powder left sitting on your kitchen bench, or a pack of protein bars lying around. Canstar Blue has surveyed hundreds of Australians to get the skinny on what protein supplement company is king. In 2017, it’s Optimum Nutrition.

What should I look for in a protein supplement?

Powder, bar, or shake – no matter what you choose, protein supplements should be just as the name describes – full of protein, and not much extra junk. A 30g scoop of protein powder should have at least 23-25g of protein, while a 60g bar should have at least 10-15g protein or so. Many brands have much higher protein content than this, so it pays to do your research. Watch out for the sugar!

Optimum Nutrition dominated in every category in our 2017 review, rated five stars for taste, texture, hunger satisfaction, variety of flavours, effectiveness, value for money and overall customer satisfaction. It was four stars overall Nature’s Way, Bodytrim and Musashi, with ALDI scoring three stars.

So what drives overall satisfaction for pumped up protein consumers? Our research found:

  • Effectiveness: 28%
  • Taste: 19%
  • Hunger satisfaction: 18%
  • Texture: 15%
  • Value for money: 13%
  • Variety of flavours: 6%

Evidently Aussies value effectiveness over all other assets of a protein supplement. After all, you’re not spending money for an enjoyable snack – you want results. Often this can boil down to how much protein content is in a bar or shake, as having a protein shake that is half sugar probably isn’t going to yield as good results as one that has a high protein count. As mentioned earlier, a 30g scoop of either WPI or WPC protein should ideally have at least 23-25g protein included, and be low in sugar and fats. However, protein supplements are not the ‘magic pill’ when it comes to bulking up or slimming down. They have to be used in conjunction with a well-balanced diet, and a healthy and consistent exercise or weightlifting regime.

Consumers also value a product that is pleasant in taste, and one that satisfies hunger. Raw protein isn’t that great to taste, which is why companies try their best to mask the taste with their own flavourings. Remember, watch the sugar content!

As for hunger satisfaction, this is probably more important for those trying to lose weight, but protein is generally a more satiating macronutrient than carbohydrates, so many are on the right track already. Once again, looking for a bar or powder with a higher protein count could help to fight off hunger for longer. As always, check the label.

Notably, many Aussies surveyed were already pretty clued up when it came to protein supplements:

  • 82% checked the nutritional information before purchasing
  • 61% buy the brands with the most protein included, suggesting they may be willing to pay more for a better protein count

Texture and value for money were also important factors for Australians. Texture might apply more to protein shakes, as who wants to drink clumps of protein? Ick! Value for money was down on the list in importance, suggesting some shoppers may be willing to spend a bit more on a protein supplement they know they will be happy with. Variety of flavours was down on the list of priorities, probably mostly because most companies produce the same sort of flavours – chocolate, vanilla, strawberry, banana, and so on. Often the more experimental or delicious-sounding flavours like ‘cookies and cream’ or ‘salted caramel’ can be a bit hit or miss, so it can pay to go with the ‘tried and true’ flavours.

How many calories are in protein?

Protein contains four calories per gram, while fat has nine calories per gram and carbs have four calories per gram as well. This is why it’s important for a protein supplement to be mostly made of protein.

  • A typical 30g scoop of Whey Protein Isolate (WPI) will have 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 lower protein content per 30g, but is a more densely-packed form of protein, allowing more powder per scoop.

  • Other, vegetarian-friendly proteins such as pea protein are generally lower in protein content again, tracking at around 20g per 30g scoop.

As for bars, they generally vary wildly, but 10-15g is about standard for a 60g bar, while some have as much as 20g of protein. To get the best ‘bang for buck’, your protein supplement should ideally have as much protein per serving possible, while being low in carbs and fats.

How much protein do I need?

The most common formula of recommended protein intake getting around is the old chestnut of 1g/lb of bodyweight. What is means is that if you weigh about 200lb (or about 90kg), you need 200g of protein per day. This equates to 2.2g per kilogram. For a lot of people, this is a lot to take in, and probably means a big adjustment to their diet.

  • 1g per lb is a convenient formula, and is best suited to those losing weight who want the satiating or hunger-busting effect that protein has compared to carbs
  • Those in caloric excess and wanting to bulk up may be able to get away with less
  • Studies have shown that about 0.8g per lb of bodyweight is safe for both ‘bulking’ and losing weight.

So a 90kg person could get away with 160g of protein, or even less based on what study you follow. Those studies show that your muscles slow the synthesis of protein after about 0.8g/lb or 1.8g/kg. Those losing weight may still want to consume more protein to bust their hunger and limit the bloating effect that carbs can have.

Sedentary people may be able to get away with even less protein content. In a western diet, very little of our food is high in protein, and is instead processed and carb or fat-laden. If inactive, and not interested in bulking up or slimming down, 1g per kilogram may be suitable. In any case, these studies may be limited in scope, so don’t take our word for it; as always, consult a medical professional if embarking on a change of diet and/or exercise.

What types of protein are there?

There are many different kinds of protein supplements, even including bars made of bug protein! Below is a list of the more common types and whether they are vegan-friendly or not.

Type of Protein Vegan Friendly?
Whey (WPC and WPI) No
Casein No
Egg No
Soy Yes
Rice Yes
Hemp Yes
Pea Yes

For vegan-friendliness, it always pays to check the label, as the vegan-friendly proteins may be made with products that are not vegan-friendly in the end, and may contain traces of animal products anyway. Whey protein is generally the most common form of protein, but if you’re lactose intolerant or a vegan, you may want to look elsewhere. Protein types are named after the source – egg protein is sourced from eggs and so on. Keep in mind that WPC and WPI generally have the highest protein content per serving, but all others generally contain at least 20g per 30g scoop, or 10-15g per 60g bar.

In any case, there are no specific proteins that target ‘weight loss’ or ‘bulking up’ – your body doesn’t differentiate. Instead, it’s what you do with the protein that matters; if you consume more than your body needs you’re probably going to put on weight, and vice versa. Just like choosing a paracetamol tablet based on a specific ailment, your body doesn’t work that way and won’t discriminate based on protein for ‘bulking’ or ‘cutting’.

Weight Loss Shake Reviews & Ratings

Top Protein Supplement Brands

The protein supplement world can generally be broken up into two categories – shake/powder, and bar. Canstar Blue has sought the opinions of hundreds of Australians to form our customer ratings, including all types of protein supplements. Here is an overview of what each brand in our review offers, to help you decide which might be best for you.

Protein Powders & Shakes

All five brands in our review have a range of protein powders and shakes.

  • Optimum Nutrition claims to be the leading protein company in the world, with the world’s bestselling protein, named ‘Gold Standard’. Gold Standard is undoubtedly its most popular line of protein powder. It mainly focuses on whey protein, specifically WPI. Gold Standard is generally the pricier product line, with tried and true flavours such as chocolate, vanilla and strawberry. A 5lb (2.25kg) tub will cost nearly $100, meaning Aussie protein shake drinkers may be willing to spend a little more to get quality, with Optimum Nutrition notably being rated five-stars for value for money.
  • Nature’s Way may be more renowned for its vitamins, but it also produces a range of protein powders. Interestingly, one of its more popular product lines is the ‘Super Greens’ protein, which is made primarily from pea protein. It also features a blend of vegetables such as kale and broccoli, as well as brown rice. For a vegie protein hit, this could be the vegan-friendly product for you. It boasts 22g of protein per tablespoon (30g) and a 300g tub is around $23.
  • As the name suggests, Bodytrim has a focus on trimming the body, rather than bulking up. But really, its products could be used for either purpose. Bodytrim produces a range of ‘Fast Shakes’, which are designed to be used as a meal replacement. Two flavours are available – chocolate or vanilla. They contain 13.1g of protein per 55g serving, and 240 calories. But remember, they are designed to replace a meal, rather than supplement your diet. These Fast Shakes cost about $45 retail price for a pack of 18 55g sachets and are designed to be used in conjunction with its 12-week weight loss program.
  • Musashi is a well renowned Australian sports nutrition company, and has a comprehensive range of protein powders. It mainly focuses on whey protein, including both WPC and WPI. Also in the range are ‘mass gainers’, designed for underweight people to gain mass. These contain a mix of WPC, WPI and carbs for a high-calorie shake. Musashi’s most popular range is arguably its ‘P20’ line, which contains about 22g per 30g scoop and less than 5g of carbs. A 900g tub of ‘High Protein Vanilla’ costs just over $60.
  • ALDI is known as a budget-friendly brand for all your grocery needs, and it also produces a range of protein powders, marketed as ‘Slim and Trim’ meal replacements. A 55g sachet costs just $2. However, watch out for those carbs – a sachet contains over 25g of carbs, with over 23g of that being sugar. This is in contrast to its mere 18g-odd protein count.

Protein Bars

Most supplement companies in our ratings produce a range of protein bars, with the notable exception being Nature’s Way.

  • Optimum Nutrition produces a range of protein bars, named ‘Opti Bars’. Opti Bars notably include a bit more protein per bar than other brands, with 20g protein per 50g bar. A variety of tried and true flavours are available, including chocolate and strawberry. Currently they don’t seem to be available to the Australian market, but a pack of 12 bars in the US costs about USD $27, which equates to about AUD $35 at the time of writing. Keep your eyes peeled for when they are released here, because they seem to have a better protein count than other bars.
  • Bodytrim produces a range of both toffee bars, and fudge bars. Also on offer is a range of slices, and protein cookies. Notably, the toffee bars contain over 17g protein, and having as little as about 1.8g of carbs, with just 1.1g of that being sugars – a pretty good ratio considering the bars are just 50g in size. A 12 pack of 50g toffee bars cost about $48, while other bars are a little bit cheaper, but make sure to check out that protein content.
  • Musashi produces a huge range of protein bars, and a lot are able to be purchased individually for a quick snack when on the go. Most are sizeable, over 60g in size, with some being 90g and containing 30g of protein. Most are centred on ‘mass gaining’ hence the relatively mixed macronutrient profile of carbs, fats and protein. There is a low-carb bar though, named the ‘P8’ series, which contains 8g protein and less than 2g carbs. A pack of 12x 30g bars costs about $30. Individual bars are available from retailers for about $4-5 for a 90g size.
  • ALDI extends its ‘Slim and Trim’ line with a range of protein bars. They benefit from being easily available in store, and cost less than $2 per bar. Bars are available in all usual flavours, including choc mint, choc fudge, cookies and cream, and so on. ALDI seems to rotate flavours so it’s a bit harder to predict what is in store at any one time. The chocolate flavour has 15.2g of protein and 211 calories from a 55g bar. Watch those carbs and fats; the chocolate flavour has 12.5g and 8.4g of these macronutrients respectively, meaning 41% of the bar’s calorie count comes from fat, and just 33% from protein.

Alternative Protein Supplement Companies

There are a number of protein supplement companies not in this year’s review because they didn’t get the minimum sample size required in our survey. However, this doesn’t mean they are any less worthy of your consideration. Increasingly, a large number of people are heading online to perhaps save a buck. About one third (34%) of those surveyed bought their protein online rather than in store. Some online supplement companies are:

  • Venom Protein
  • Bulk Nutrients
  • VPA Protein

Many of these online companies do away with fancy packaging and marketing spin, and instead focus on just no-frills protein. They generally prefer you to buy in bulk – 5kg+ at a time – and you’ll have to watch out for shipping costs.

Another brand that has seen a lot of hype is Quest. Quest specialises in protein bars, and their nutrient profiles feature some of the best protein-to-carb ratios in the industry. As a consequence, you can also expect to pay a fair bit – about $4 for a 60g bar. In any case, no matter what protein brand you decide to go for, it pays to always do your research, read the nutrition labels and consult a qualified professional with any questions, or before undertaking a change in diet or exercise.
