The protein bar market in Australia is worth hundreds of millions of dollars and growing. Which means it also attracts more marketing, more greenwashing, and more products built to look good on a label rather than perform well in your body.
1. At Least 15g of Protein From a Complete Source
The minimum threshold for a bar to function as a genuine protein supplement is 15 grams of complete protein per serve. This rules out bars where a significant portion of the protein comes from collagen, which lacks tryptophan.
2. Zero or Minimal Sugar Alcohols
Sugar alcohols — erythritol, maltitol, xylitol, sorbitol, isomalt — cause significant digestive discomfort in a large portion of the population. A clean protein bar has zero or trace amounts.
3. Added Sugar Under 5 Grams
There is a difference between naturally occurring sugars and added sugar. Under 5g of added sugar per bar is a reasonable benchmark for a genuinely clean product.
4. A Short, Readable Ingredients List
If you cannot read it, question it. Under 15 ingredients is a reasonable benchmark. Under 10 is exceptional.
5. A Meaningful Protein-to-Calorie Ratio
Divide the protein grams by total calories and multiply by 100. For a bar to genuinely qualify as a protein supplement, you want this above 25–30 percent.
6. No Artificial Colours or Unnecessary Additives
Artificial colours serve no nutritional function. Their presence tells you the product is prioritising visual appearance over ingredient quality.
7. Transparent Nutritional Information
A quality protein bar brand publishes full nutritional information without relying on front-of-pack claims to distract from the label.
