For consumers like you and I, this is great news as it means there is a lot more choice in the protein bar ranges on offer, such as the ingredients that are used, the level of protein contained in the bar and also solutions for various intolerances, including gluten and dairy free.

What are protein bars good for?

As protein bars contain a high level of protein, they are particularly good for fitness enthusiasts to repair and strengthen muscles after a hard workout as part of their recovery plan. They are also a convenient snack for people who have busy lifestyles and always on the go. They are easily stored so are good for traveling or for taking to work for a quick lunchtime snack. Protein bars usually also contain additional vitamins and minerals, which all help support a healthy lifestyle.

What are the benefits of protein bars for weight loss?

The high level of protein can make you feel fuller for longer so can work as part of weight loss plan, but it is still important to have a balanced diet. Your doctor or nutritionist will be able to advise the best course of action, and to personalize a plan to fit your individual needs.

When is the best time to eat a protein bar?

This depends on the reasons for eating protein bars. If the protein bar is to replace a meal or as a convenient snack, then simply enjoy one when you otherwise would have had a meal. If, however, you are using protein bars as part of your workout regime, the best time is when you train or shortly afterwards to help aid recovery.

What is the difference between a protein bar and an energy bar?

An energy bar will usually contain a higher level of carbohydrates to create the food energy, where as protein bars usually have lower amounts of carbohydrates than energy bars, but a much higher level of protein.
