Trending Questions

What makes this the best protein bar?

The new Custard Protein Bar is a very unique and innovative product and an industry first in the protein bar sector with a Custard filled centre. We have worked with the best manufacturer in Australia with the highest food grade certifications to finally bring to life the best tasting and textured protein bar around. With its unique soft Custard filled centre, amazing flavours and inclusions, every mouthful is a joy.
Where can I purchase these Custard bars?

Our Custard Protein Bars can be found at Coles Supermarkets, Coles Express Service Stations, Chemist Warehouse, and are also available for purchase on our website.
When should I eat this bar?

Anytime during the day for a quick protein-filled snack.
What is the custard filled centre made from?

The Custard filled centre in our Custard Protein Bars are made from our actual Custard Casein Protein powder. We supply our manufacturer with our very own Custard Casein Protein powder which they then use to make the Custard filled centre in our bars. 
Why are there so many ingredients?

Our Custard Protein Bars use our very own Custard Casein Protein powder to fill the centre. In essence this also has to be incorporated on our label (two products on one label).

When it comes to labelling and ingredients, we strive ourselves on transparency. Yes we probably go over the top but we choose to over label and provide our customers with as much information as possible. Unfortunately, under labelling does occur in the industry, but being 100% transparent, and above the standard required procedures, is our choice.
How many bars can I eat daily?

We recommend not exceeding 1 bar per day.
