How to choose the right protein bar?

With so many different products to choose from, finding the best protein bar isn’t always easy. With so many ingredients, purposes, and flavours to choose from, it is important to make a few considerations before you buy.

  • Protein Content: The best protein bars have the highest protein content, so be sure to inspect this whenever buying. Some are deceptively low on protein, with a good average being around 20g per bar. Those with lower protein content may offset the difference with other macronutrients like carbs, which may be preferable depending on whether you’re exercising before or after you eat it.
  • Carb Content: The carb content of a protein bar is also important, with around 15-20g being the idea amount. Remember, you want more protein than anything else, so make sure to check the proportion of carbs to protein. However, higher carb content is good for certain purposes, typically high-cardio workouts they offer more sustained energy.
  • Sugar: Always try to buy protein bars with low sugar content, as this is an unnecessary ingredient that can hamper diets and workouts. Anything with around 1 to 2g of sugar is recommended and be sure avoid anything with 5g or more.
  • Flavour: Although mostly subjective, be sure to consider the flavour of the bar in relation to the ingredients. Yes, something more flavourful such as cookies and cream protein bar may taste amazing, but it should never be at the expense of healthy ingredients - you want protein and nutrients, not just a tasty snack!
What is the best kind of protein bar in the UK?

  • Nutrition Bars: This type of protein bar balances high protein content with other nutrients and vitamins.
