Are protein shakes good for endurance athletes?


Protein is just as important for endurance athletes as it is for weightlifters. It helps with recovery, injury prevention, immune function, and much, much more. Many endurance athletes do not consume nearly enough protein, which can have a serious negative impact on their performance. If you do not get enough protein when training hard, your body will break down muscle for use as fuel. This will eventually make you slower, no matter who you are. Protein supplements are therefore a great way to ensure that you are getting the nutrition you need to recover and perform at your best.

Endurance athletes require more protein than sedentary individuals to support muscle repair and recovery after long training sessions. It is recommended that endurance athletes consume 0.4 grams of protein per kilogram of bodyweight per meal across a minimum of four meals in order to reach a minimum of 1.6 grams of protein per kilogram of bodyweight per day. For an athlete weighing 150 pounds, this amounts to well over 100 grams of protein!

Getting enough protein from normal food can be challenging for some endurance athletes, especially those with dietary restrictions. This is where protein supplements come in handy. Adding a protein shake to your diet is an easy and convenient way to ensure that you are meeting your protein goals. That said, not all protein shakes are created equal.

What are the best protein shakes for endurance athletes?


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 shaker bottle, and a little extra time and effort. Some people, prioritizing convenience, prefer to buy ready-to-drink protein shakes, but if they knew what they were drinking, they would feel sick to their stomach.

Ready-to-drink protein shakes are full of emulsifiers, stabilizers, thickeners, sweeteners, and flavors. Ingredients like these improve characteristics like taste, texture, and shelf stability, but can cause uncomfortable side effects and long-term gut damage. This is worrisome because more and more research shows that disruptions to the composition and function of the gut microbiome (the collection of microorganisms that help you digest food) can play a role in the development of a number of chronic diseases.

Gut health also plays an important role in athletic performance. A healthy gut microbiome can improve energy metabolism by supplying muscles with oxygen and nutrients during intense exercise. It can also reduce inflammation and expedite tissue repair, helping to improve performance and expedite recovery. I therefore recommend that you make protein shakes with protein powder. That said, not all protein powders are created equal either, and many contain the same additives found in ready-to-drink protein shakes! 

Why drink wholesome


drink wholesome is additive-free.

One of the reasons why we make the best protein powder for endurance athletes is that we do not use food additives. Most protein powders, on the other hand, are full of food additives.

Food additives may improve characteristics like taste, texture, and shelf stability, but they can also cause uncomfortable side effects and long-term gut damage. Basically, because they look nothing like real food, food additives are hard to digest. They therefore 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, causing bloating and stomach pain. Gas also slows colonic transit (the amount of time it takes food to travel through the colon), which can lead to constipation. Over time, food additives can add up (especially if you drink a protein shake every day), and disrupt regulatory pathways in the intestine. Eventually, this can lead to the development of inflammatory bowel disease (IBD) and systemic inflammatory disorders.

When buying protein powder, one additive to avoid in particular is artificial sweeteners. Artificial sweeteners are among the most harmful food additives in the long term as they alter the composition of your gut microbiota. 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 poorly absorbed by the gut, meaning they feed your hungry gut bacteria. They can also cause diarrhea because they draw water into your intestines. Now you finally have something to blame for those post-protein shake trips to the bathroom!

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

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, additives are ingredients that you cannot pronounce. Food additives are not the only thing to avoid when buying protein powder, however. There are several other ingredients that can upset your stomach.

the alternative:

Protein Matrix Comprised of (Whey Protein Concentrate,  Whey Protein Isolate, Calcium Caseinate, Micellar Casein, Milk Protein Isolate, Egg Albumen, Glutamine Peptides), Polydextrose, Sunflower Creamer (Sunflower Oil, Corn Syrup Solids,  Sodium Caseinate, Mono- and Diglycerides, Dipotassium Phosphate, Tricalcium Phosphate, Soy Lecithin, Tocopherols), Natural and Artificial Flavor, MCT Powder (Medium Chain Triglycerides, Nonfat Dry Milk, Disodium Phosphate, Silicon Dioxide), Lecithin, Cellulose Gum, Salt, Yellow 5, Sucralose, Acesulfame Potassium, Papain, Bromelain.

*This is the actual ingredient list of one of the best-selling protein powders in the United States.

drink wholesome is dairy-free.

Another reason why we make the best protein powder for endurance athletes is that we do not use dairy-based proteins. Many protein powders are made with whey and casein, which are byproducts of cheese and yogurt production, and known to cause digestive issues. This is especially true 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. 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 and cause side effects. 

drink wholesome is made with real foods.

A final reason why we make the best protein powder for endurance athletes is that we do not use protein isolates. Most protein powders, on the contrary, are made with protein concentrates and/or isolates, foods stripped of everything but the protein. They appear on the ingredient list as “pea protein” and “whey protein” as opposed to “peas” and “whey.”

I will not go into the details, but protein concentrates and isolates undergo heavy mechanical and chemical processing before becoming protein powder. 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.

If you think about it, your gut was designed to digest naturally occurring foods, not laboratory formulated imitations, so if you feed it anything but real food, it might get upset. The long term implications of eating processed foods are still not well understood, but more and more research is finding that it can alter the composition of your gut microbiota, and lead to permanent damage to your gut microbiome.

Your gut does more than just help you to digest food; it protects against pathogens, educates your immune system, and affects directly or indirectly most of your physiologic functions. Disruptions to the gut microbiome have therefore been linked to the development of many chronic diseases. It follows that it is in your best interest to avoid protein powders made with protein concentrates and isolates.

Instead of using protein concentrates or isolates, we make the best protein powder for endurance athletes with whole foods like egg whites and almonds. Egg whites are simply pasteurized and dried before becoming protein powder. Almonds are just roasted, pressed to remove some of the oil, and ground. Whole foods like these are an easy to digest, gut-friendly alternative to protein concentrates and isolates.

Whole foods contain a variety of enzymes and other digestive aids that help to break down the food, making it easier for the body to absorb the nutrients. Protein isolates and concentrates, on the other hand, have been stripped of these digestive aids, making them harder for the body to digest and absorb. Moreover, minimally-processed plant-based foods like almonds are rich in fiber, which helps promote healthy digestion and regular bowel movements.

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, naturally alkaline, 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 powder than with any other type of protein powder. If you cannot eat eggs, try our vegan almond protein powder. We prefer almonds to other plant protein sources because they are more gut-friendly. Research suggests that almonds possess prebiotic properties that can improve the diversity and composition of the gut microbiome.
