Protein bars vs protein shakes.

What is a protein bar? 

Protein bars are a high protein snack designed to help people boost their protein intake. Many people enjoy protein bars because they are convenient. You can eat a protein powder pretty much anywhere at any time, and doing so requires no cooking or cleanup. The average protein bar contains 10–20 grams of protein. 

What is a protein shake? 

A protein shake is a high protein drink designed to help people boost their protein intake. There are two types of protein shakes, ready-to-drink (store-bought) protein shakes, and protein shakes made with protein powder. In order to make a protein shake with protein powder, you have to mix the powder with milk or water. This requires a blender or a shake bottle, and a little extra time and effort. The average protein shake contains 20-30 grams of protein. 

Protein bar vs shake.

Protein bars and shakes are basically two different forms of the same thing: a protein supplement. That said, there are a few differences between the two.


Per gram of protein, protein shakes tend to be cheaper than protein bars.


Protein shakes typically contain more protein than protein bars. They also contain less sugar and fewer calories, which is not necessarily an advantage, but it could be.


In terms of convenience, there is no virtually difference between store-bought protein bars and store-bought protein shakes. When it comes to making protein supplements at home, however, there is a huge difference. Homemade protein bars take at least an hour to make because they need to be refrigerated. Homemade protein shakes, on the other hand, can be made in just seconds if you have a good blender.


It is easier to swallow your food than it is to chew it. For someone who has trouble eating solid food, this is a good reason to choose protein shakes over protein bars.


It is easier to digest food in liquid form, so if you have gut issues or a sensitive stomach, protein shakes are a better choice than protein bars.


Protein bars do have one distinct advantage over protein shakes: they are easier to transport. A protein bar is far lighter than a protein shake, and takes up less space in your bag, car, etc. That said, if you were looking to stock up on protein supplements, buying protein powder is the way to go. You can pack far more protein in your pantry in the form of powder than in the form of bars.

Do your own research. 

Considering variables like cost, nutrition, convenience, consumption, digestibility, and portability, protein shakes are the clear winner in my book. This is not to say that protein bars are a waste of money, it is just that if I were to choose one over the other, I would choose protein shakes every time.

Given the wide variety of protein bars and shakes on the market, it is important to know that not all protein supplements are created equal. Unfortunately, many store-bought protein bars and shakes are full of food additives, heavily-processed ingredients known to cause uncomfortable side effects. This is why I recommend that you make your own protein shakes with protein powder. Unfortunately, however, many protein powders also contain food additives. You will therefore have to read ingredient lists to find the good ones. Keep reading to learn more about the top ingredients to avoid when buying protein supplements.

Avoid food additives.

Again, many protein bars, shakes, and protein powders are full of food additives. Although not necessarily bad for you in small quantities, additives can add up quickly (especially if you eat a protein bar or drink a protein shake every day) and cause gastrointestinal (GI) side effects like bloating, constipation, diarrhea, gas, and stomach pain. This is because food additives are, generally speaking, hard to digest. They sit in your gut for longer than food should, which gives your gut bacteria more time to eat. As they eat, these bacteria produce gas, which causes bloating and stomach pain. Gas also slows colonic transit (the amount of time it takes food to travel through the colon) and can lead to constipation.

In the long term, food additives can disrupt regulatory pathways in the intestine, which can result in the development of inflammatory bowel disease (IBD) and systemic inflammatory disorders. Artificial sweeteners are among the most harmful additives in the long term as they alter the composition of your gut microbiota (the collection of microorganisms that help you digest food). This can lead to serious, chronic GI problems, widespread inflammation, and permanent damage to the gut microbiome. Some sweeteners, especially sugar alcohols like xylitol, are also poorly absorbed by the gut (meaning they feed those hungry gut bacteria) and cause diarrhea because they draw water into your intestine. Now you finally have something to blame for those post-protein supplement trips to the bathroom!

Here is a list of the most common food additives in protein supplements:

acacia gum, acesulfame potassium, artificial flavors, aspartame, carrageenan, cellulose gum, dextrin, dextrose, erythritol, gellan gum, guar gum, gum arabic, inulin, locust bean gum, “natural” flavors, maltodextrin, rice syrup solids, soy lecithin, silica, sucralose, sunflower lecithin, xanthan gum, xylitol

When it comes to identifying food additives, go with your gut. 😉 As a rule of thumb, they are the ingredients that you cannot pronounce. Food additives are not the only thing to look out for when buying a protein supplement, however. There are several other ingredients that can upset your stomach.

Avoid dairy. 

Dairy-based proteins like whey and casein, which are byproducts of cheese and yogurt production, are known to cause digestive issues, especially for people with lactose intolerance and irritable bowel syndrome (IBS). Over one in three Americans are lactose intolerant, and the prevalence of IBS is somewhere between 10 and 15 percent in the United States. It follows that you may be lactose intolerant or have IBS and not even know it. Irritable bowel syndrome (IBS) is a poorly understood condition, and it is unclear why dairy triggers symptoms. Lactose intolerance, on the other hand, is clearly understood. People with lactose intolerance are unable to fully digest lactose, the sugar in dairy. As you just learned, partially digested food feeds the bacteria in your gut, which produce gas. 

Avoid protein concentrates and isolates.

Finding an additive-free, dairy-free protein supplement is hard. Finding an additive-free, dairy-free protein supplement made with real foods is next to impossible. Why? Most protein supplements are made with protein concentrates and isolates, foods stripped of everything but the protein. They are listed on the ingredient list as “pea protein,” for example, as opposed to “peas.” We will not go into the details, but protein concentrates and isolates undergo heavy mechanical and chemical processing before becoming protein supplement. Sometimes, manufacturers use chemical solvents like hexane to isolate (separate) the protein from the food. This means that what you end up putting into your body looks nothing like real food. The problem with ingredients that look nothing like real food is that they are hard to digest; your gut always prefers the real thing, not some heavily-processed imitation.

Instead of using protein concentrates or isolates, we make protein powders with egg whites and almonds. Egg whites are simply pasteurized and dried before becoming protein powder. Almonds are just roasted, pressed, and ground. Minimally-processed ingredients like these are an easy to digest, gut-friendly alternative to protein concentrates and isolates.  

Unless you have a sensitivity or allergy to eggs, egg white protein is the best protein for your gut. Egg whites are low in fiber, low-FODMAP, and have the highest protein digestibility-corrected amino acid score (PDCAAS) of any whole food. Our customers have experienced fewer digestive issues with egg white protein than with any other type of protein. 

If you cannot eat eggs, try our almond protein powder. Unlike protein concentrates or isolates, almonds contain lots of healthy fats, fiber, and other nutrients like calcium and vitamin E. We prefer almonds to other minimally-processed plant protein sources because they are more gut-friendly. Research suggests that almonds can improve the diversity and composition of the gut microbiome. Research also suggests that almonds possess prebiotic properties, meaning they stimulate the growth of healthy bacteria in the gut.
