Product Information

Protein Bars contain a blend of easily digestible proteins (20 grams per bar) in the form of whey, casein and soy protein. It is important to consume protein in close proximity to training sessions (i.e. before or after training) in order to maximize training adaptations.

Protein intake is often overlooked by endurance athletes. Protein Bars provide an appropriate quantity of high quality protein for before or immediately post exercise.

Key Features

  • • High protein formula to promote training, adaptation and recovery
  • • Each bar contains 20 grams of easily digestible protein
  • • A high quality blend of whey, casein and soy protein
  • • Promotes the rebuild of muscle following exercise

Product Uses
Recommended Usage

Protein Bars are a convenient source of protein on the go to acheive the recommended 20-25g of protein every 3-4 hours.

Aim for 1-2 Protein Bars a day, consumed between meals, before and/or after a workout.


Adapting to the demands of endurance training is facilitated by increased muscle protein synthesis whereby new proteins are made in our muscles after each training session. The muscle becomes reconditioned so that it can better withstand the physical demands during the next training session.

For optimal protein synthesis to occur, it is crucial that we consume high quality protein given that protein contains amino acids that make new proteins. Protein Bars contain a blend of easily digestible, quality proteins that act as a trigger to stimulate protein synthesis.

When should I eat these? Are they a meal replacement?

We always recommend that food should come first in your diet. However, Protein Bars are a convenient source of protein on the go to achieve the recommended 20-25g of protein every 3-4 hours.


Do these bars contain nuts?

Protein bars are made externally and yes, the chocolate and peanut bar contains nuts and the mint chocolate bar is produced in the same place so it cannot be guaranteed nut free.


Should I eat one of these or have REGO after exercising?

If you are training again sooner and/or hydration is a concern, we suggest having REGO Rapid Recovery post exercise. Solid foods like Protein Bars take longer to digest compared to liquids like REGO Rapid Recovery.


What is the recommended frequency of consumption?

Aim for 1-2 Protein Bars a day, consumed between meals, before and/or after a workout.


Will the chocolate melt in my jersey when cycling?

They have the potential to melt in warm conditions. In this situation, GO Energy bars may be a better choice as they are designed to be used during exercise.


What is the sugar content in these bars?

Protein Bars contain 17-18g of sugar per bar to aid taste.

Simon Lester

Tasty and good consistency.

Brandon Myatt

The bars are the best out there in my opinion, I have one almost everyday. I would have given 5 stars but I think it’s a little expensive, there’s a lot of profit there selling them for what works out to be around £1.50 each haha

Wesley Brown

Love these, tastes like a snickers!!

Great as a back up snack during training plans.

Nice product, not as minty as I thought it would be, but still tastes good. Would recommend for before and after rides.

Jonathan Howgrave-Graham

Nice post ride snacks, especially if your heart rate’s been in the cardio or harder zone, when your body continues to burn energy hours after.


Although I enjoy eating when out for a long cycle ,It wasn't minty enough for me and I'm not a chocoholic.
