Bulk Nutrients muscles in on top spot for protein supplements

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. It almost needs a whole supermarket aisle to itself these days. 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.

Canstar Blue surveyed more than 1,200 adults to ask about the protein supplements that they use, with the 10 brands included rated in the following order for overall customer satisfaction:

  • 1st Bulk Nutrients
  • 2nd Optimum Nutrition
  • 3rd Atkins
  • 4th BSC
  • 5th Sustagen
  • 6th Aussie Bodies
  • 7th ALDI
  • 8th Musashi
  • 9th Nature’s Way
  • 10th Bodytrim

The survey found effectiveness (32%), taste (22%) and value for money (22%) were the biggest drivers of satisfaction for consumers, with texture (15%) and variety of flavours (10%) of less importance. But with so many options available, you have every right to be a picky eater! If you’re looking to get your summer body ready, read on to find out which protein supplement may be the best option for you. And here are some of the key takeouts from our 2018 survey:

How many calories are in protein?

Proteins Calories

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 – you don’t want to be filling up on something that will take you further away from 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 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 can 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?

With 56% of survey respondents indicating that they researched how much protein they should be having a day, figuring out your recommended intake is obviously important to many, as well as potentially a bit confusing. 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 ‘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 cravings 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.

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 how easily you can get you 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 to protein supplements.

Ultimately which protein type and supplement brand you choose will be your own personal decision, but researching what’s out there, as well as 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 6,000 Australian adults across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics.
