What You Should Know Before Buying protein bars for runners


Protein bars come in flavors such as dark chocolate, cookie dough caramel, mint, apple pie and more. You can choose a flavor of protein bars by your taste preference. However, there are some with a lot of artificial flavouring or sweetener, which could make it more unhealthy.


Protein bars are a really good option as a snack and for fulfilling your protein needs. However, most of the protein bars contain one or more common allergens like gluten, fish, peanuts, milk, soy protein, eggs, and nuts. If you are allergic to any one of these options or you are a vegan, then be careful to research and look at the ingredients of the protein bar before buying any.

Fiber content

Fiber is one of the essential components of your protein bar. Fibers help in lowering cholesterol, controlling sugar levels, and helps to maintain bowel health. Aim for a protein bar with 6- 15 grams of dietary fiber. Make sure that you are not exceeding your daily fiber intake because some bars are high in fiber and constant overconsumption of them can cause bowel problems and bloating. Protein bars contain a varied amount of fiber ranging from 6gram to even 20 grams. Choose a protein bar according to your nutritional requirements.

Sugar content

Opting for a protein bar to replace a snack is a good habit to nurture. But in some cases, many protein bars in the market are a candy bar in disguise. A protein bar should contain ideally low-fat content and high protein content to give you the most benefits. So if you want a good and nutritious protein bar, aim for a bar not more than 5-8g of sugar per bar.

Questions and Answers About protein bars for runners

When should runners eat protein bars?

Protein bars are recommended after a workout because they help in building any slight muscle fibers tear because of running. A bar rich in carbohydrates is usually recommended instead of a protein bar before 45 mins of workout because protein sugars and fiber slow down the digestive system. In addition to that, no two bodies are the same and in most of the runners, it is observed pre-workout protein cause GI disturbances. If your workout window is more than 90 minutes you can take an energy-rich source such as an energy drink in between the run.

Do protein bars make you gain muscle?

Yes, protein bars can help you gain muscles. Our skeletal muscles are composed of almost 80% of protein excluding water. Skeletal muscles are made up of bundles of thread-like structures called myofibrils which are made up of thick and thin filaments comprising of myosin and actin respectively.
These are large protein molecules so we can say the building block of our muscles is proteins. Because of this, we can say protein bars help with muscle gain. But remember balance is the key. Take proteins in a balance with other nutrients because taking excess can cause more harm than benefit.

What difference does the type of protein make?

Amino acids are building blocks of proteins. And proteins are building blocks of our muscles.  All amino acids come from vegetable sources and animal sources. Animal sources are considered ideal sources of protein because they provide all amino acids needed for the body also known as complete proteins. Plants lack some of the amino acids necessary for the body so are incomplete proteins. We intake proteins from animals and plants. Our body digests them into simple amino acids which are then used for building muscles. Make sure to add animal sources in diet so you don’t lack essential amino acids.

How soon before a workout should I eat a protein bar?

There is no hard and fast rule for protein intake. Pre-workout protein bars give you energy and essential amino acids for your body and muscles. As we don’t want to feel heavy before a workout so we can eat a protein bar almost 30-60 mins before the workout. The intake of protein bars entirely depends on body needs and may vary from person to person but as we don’t want to feel heavy and bloated before a workout.
