protein bar buying guide

Do you want to buy a good protein bar? This is all you need to know.

A short explanation: What are protein bars?

Image of protein bars

A protein bar is a type of nutrition bar that contains a higher level of protein than other types, along with other ingredients that are beneficial for increasing muscle mass and improving overall health. The type of protein can vary from product to product, as can the additional ingredients included in the bar, with good protein bars offering purer forms of protein that are easier to digest. Vegetarian and vegan protein bars are also widely available.

What are the benefits of good protein bars?

A notable benefit of the best protein bars is that they supplement your diet with more protein. The implication of this is wide ranging, as more dietary protein helps with weight loss, build muscle, and even recover faster after exercise. Some may use a great protein bar to have a healthy snack that reduces their appetite though the high-protein content, while it can also help refuel your body’s energy levels post workout. Better still, the best protein bars can encourage muscle growth due to the high protein content. This makes them useful for eating on the go or as a post workout snack.

How to choose the best protein bar in 2024?

Choosing the best protein bar can be difficult if you don’t know what you should be looking for. Here are some things to consider:

  • Nutritional Requirements: Protein bars offer an easy way to supplement your diet with more protein, but it’s important to choose one that provides the right amount of each. For it to be effective as a protein supplement, then the bar requires much more protein than anything else. For the best protein to other nutrient ratio, look for something that contains around 20g of protein and no more than 5g of sugar.
  • Protein Content: The best protein bars in terms of their protein content have around 20g of protein with no more than 9g of fats and 5g of carbs. This results in less total calories, meaning more of the bar is dedicated to the protein. So always check how much protein is included and aim for something around the 20g mark. It also helps offset the taste of the other ingredients (e.g. artificial sweeteners).
  • Purpose: As protein bars can contain a variety of ingredients, it should come as no surprise that they can all perform many functions. For instance, you may want to buy a protein bar to help curb your appetite in an effort to lose weight. If so, then look for a bar with high protein and very few carbs and sugars. Meal replacement bars, which have higher carb contents, are perfect for after a workout.

Which types of protein bars are available to buy in the UK?

There are so many different protein bars available today, which may make it confusing to choose one that suits you best. Here are some of the most popular types of protein bar available to buy:

  • Organic Protein Bars: If you want an all-natural snack every now and then, a organic protein bar is a great option. These protein bars use all-natural ingredients and are free from pesticides, making them a much healthier snack, especially if you work out.
  • Vegan Protein Bars: A vegan protein is a type of plant protein bar that does not use any dairy products. This results in less protein content. Vegan protein bars use quality ingredients, usually organic, and vegetized proteins.
  • Mixed Source Protein Bars: These protein bars use a combination of whey, soy or any other type of protein. This results in higher protein content compared to vegan protein bars. The other ingredients used are based on the type of bar.
