Why They Keep Choosing On Call
Real experiences from professionals who rely on On Call every day.
My favourite protein bars!
I love On Call bars so much! They’re the only protein bars that I actually feel good after eating. So happy they came out with the variety pack because I can’t choose which flavour is my favourite and can easily switch it up everyday.

Long lasting fuel
Long lasting fuel without the typically overly sweet taste! These are perfect for long shifts when I don’t always have time to have a full meal, or I’ve even been taking them for hikes or on the go. Chocolate brownie is my favourite.

Great taste and easy on the stomach
Really impressed with these. I had the blueberry vanilla bar before heading out for the day and it tasted super good. I have a pretty sensitive stomach and it didn’t sit heavy at all, which was nice. I felt good after eating it and will definitely be ordering again.

This bar was absolutely delicious!
This bar was absolutely delicious! I am picky about taste and have tried countless protein bars over the years. I can confidently say this is the best one. It is not overly sweet or artificial tasting. It fuels me during a busy clinic. Best of all, it is made with clean ingredients.

Born in the Hospital
As surgeons, we eat on the run. Between cases. On overnight calls. At 2am when the cafeteria's closed.
Every bar we tried either tasted artificial, sat heavy, or left us crashing. So we built one that didn't.
Two years getting the ingredients, texture, and taste right. Not just the macros, the actual experience of eating it.
That's On-Call. Ready when you are.

STILL DECIDING? WE'VE GOT YOU COVERED
What makes On-Call® different?
On-Call® was created by surgeons who needed something substantial to eat during long, unpredictable shifts. With 18–19 g of plant-based protein, 8–9 g of fibre, and no artificial sweeteners or sugar alcohols, it’s made for busy days when your next break can’t be planned.
Will it keep me full?
On-Call® was made for the stretch between meals. With 18–19 g of plant-based protein, 8–9 g of fibre, carbohydrates and fats, it’s a substantial bar for the times when a quick bite needs to count.
What is it sweetened with?
On-Call® is sweetened with dates and agave, with no artificial sweeteners or sugar alcohols.
When should I eat it?
Between meals, during a long shift, before or after training, or while travelling. Keep one in your work bag, desk or gym bag for whenever your day gets ahead of your next meal.
Is it a meal replacement?
No. On-Call® is designed to bridge the gap between meals, not replace a balanced meal. It’s a convenient option when you need something substantial but don’t have time to sit down for a meal.
Which flavour should I try first?
Not sure where to start? Try the Starter Pack. It includes all three flavours — Peanut Butter Chocolate Chip, Chocolate Brownie and Blueberry Vanilla — so you can try them all and find your favourite.
