A common practice is mixing coffee with protein shakes.  Although this combination can provide you with the energy boost you are looking for, adding hot water to whey protein can possibly denature the protein (especially if the water is boiling). 

Thus, you may be wondering whether whey protein powder has caffeine already included.

Does protein powder have caffeine? Most protein powder brands do not have caffeine included.  However, some brands, such as Muscle Milk, Gold Standard, Ensure Max, Dymatize, Iconic, and Orgain, have “mocha” or “coffee” flavored options, which do include small amounts of caffeine (anywhere from 15-120 mg per serving).

This article will explore more than 30 brands of protein supplements to determine which ones contain caffeine and how much they contain in one serving compared to a cup of coffee. 

I’ll also explain whether it’s safe to consume protein powders with caffeine and whether you should buy these products.

Why Does Protein Powder Have Caffeine?

Why does protein powder have caffeine

Even though some protein powders contain caffeine, it is not the case for most. So, why include caffeine with whey protein?

Caffeine is one of the most studied performance aids in sports. Although it is most often consumed in coffee or tea, some people don’t like the taste of those options or it’s not as convenient, which leads to finding alternatives (such as protein shakes) to get the benefits of caffeine.

Improves Performance

Caffeine is a stimulant of the central nervous system. This means that it can fight fatigue and boost energy levels. Thus, drinking caffeine before workout sessions can significantly increase performance

In a study done on seven adult cyclists, they were given a placebo or some caffeine (4 mg per kilogram of body weight). The study concluded that those who took caffeine improved the time to exhaustion by 12%. This means that they could last longer than those that didn’t take any caffeine. 

Easy To Carry Around

One of the other benefits of having whey and caffeine together is that it makes it easier to carry around. 

Instead of taking a mug with your coffee and another bottle with your protein shake, you can just take the powdered form with the caffeine and mix it up in a single shaker cup. 

Is It Safe To Consume Protein Powders That Have Caffeine? 

Yes, it is safe to consume protein powders with caffeine. But, you need to be careful with how much caffeine you consume. A recommendation of 3-6 mg per kilogram of bodyweight brings several performance benefits. However, having more than 9 mg per kilogram of body weight can have harmful effects. 

A high caffeine intake can lead to sleep problems (insomnia), anxiety, headache, nausea, nervousness, and irregular heartbeat. Remember that it is a stimulant of the central nervous system. Thus, it is always important to check with your doctor when adding caffeine products, especially if you have a heart disease history. 

Also, caffeine can irritate your stomach. Thus, people who often have acid reflux or Irritable Bowel Syndrome (IBS) might want to ingest protein shakes with caffeine, not regularly. 

Should You Buy Protein Powders That Have Caffeine?

Should you buy protein powders that have caffeine?

Here are a couple of cases when you might want to consider buying a protein powder with caffeine. 

You Don’t Like Coffee or Tea

For those that don’t like coffee or tea but still want to get that energy boost from coffee, buying a protein shake with caffeine can provide you with the needed caffeine to help you have sufficient energy levels. 

Weight Gain Phase

Whether you are a bodybuilder or just someone trying to put on muscle mass, adding too much volume to your stomach can increase your fullness levels and prevent you from reaching your total calories during the day. If you add a cup of coffee along with a protein shake, it might make you feel overly full. 

Thus, adding only one beverage will prevent you from feeling too full. This means that you can still eat the rest of the calories during the day without feeling stuffed.

You Train Too Early

Waking up early and eating a meal right away, and at the same time, having enough energy levels to train might be challenging. 

If you need to train with something in your stomach, a protein shake can help you out, and consuming protein that has caffeine included can also help increase your alertness if you’re not a morning person.

You Train After Work

If you are training after a long day at work, you might be too tired to go to the gym. Taking a protein shake with caffeine can be a handy snack that gives you that energy boost for you to go to the gym. 

3 Best Protein Powders That Have Caffeine

If you’re in the market for protein powders that have caffeine included, I recommend the following three options: 

IsoPure Espresso – Best Overall

IsoPure is one of my favorite brands when it comes to protein shakes. It offers less than 1 gram of both carb and fat, making it the best option to ensure that you only add protein to your meals. 

IsoPure has an espresso version with 40 mg of caffeine, similar to one shot of espresso or half a cup of coffee.

Since it is a whey protein isolate, it is easier to digest, which won’t cause an upset stomach. It also has a reduced lactose content, making it the best option for those with lactose intolerance. 

Additionally, if you are very sensitive to caffeine, meaning that only one cup of coffee might affect your sleep patterns. A lower caffeine option like Isopure is the best option to start. 

Dymatize ISO100 Hydrolyzed Protein Powder in Dunkin’ Mocha Latte Flavor

Even though the Dymatize ISO100 Hydrolyzed Protein Powder has the same macro content as the Isopure, it has the benefit of containing more than twice the amount of caffeine. It has 95 mg of caffeine, representing one cup of coffee. 

This is ideal for those that need an energy boost and have a higher tolerance to caffeine.

Muscle Milk Coffee House

Muscle Milk Coffee House has the advantage that it has all the macros (protein, carbs, and fats). It contains 9 grams of fat, 21 g of carbs, and 32 g of protein. If you have a hard time adding food to your day, adding a shake with all the macros can act as a meal replacement. 

Additionally, it is the highest in caffeine content, with 120 mg of caffeine per serving. This represents having 2 cups of coffee. 

This is ideal for those looking to gain some weight and need extra calories in their diets. With that said, it is not for those that have a lower calorie intake during the day (like those in a weight loss phase). 

Protein Types & Caffeine

Here I’ll discuss whether different types of protein (casein, hemp, soy, etc.) have caffeine. 

Does Casein Protein Have Caffeine? 

No, casein doesn’t naturally contain any caffeine. In most cases, thanks to being a long-digesting protein, it is typically used before going to bed to help provide a steady amino acid release. Thus, it is not very common to find casein protein that has caffeine in it. 

Does Soy, Hemp, or Pea Proteins Have Caffeine? 

Vegetable proteins like soy, hemp, and pea don’t naturally contain caffeine. If you ever find a vegetable protein with some caffeine, it was artificially added to the mix and will be clearly labeled on the bottle

Does Coffee Flavored Protein Powder Have Caffeine? 

Yes, in most cases, the coffee-flavored protein powders have caffeine in them. Since people regularly drink coffee for its caffeine content, a protein shake flavored with coffee is expected to have the same energy-boosting results. 

For example, protein shakes like Iconic Protein Coffee, Café Latte, or Ripple – Vegan Protein Shake contain caffeine. They usually obtain this by adding ground coffee beans to the formula, thus providing the flavor and the caffeine content. 

However, you can still find coffee-flavored protein that doesn’t have caffeine added.  For example brands like Premier Latte have a Caffe Latte powder protein that won’t provide you with any caffeine. This is obtained by adding natural coffee flavors but not coffee powder It provides the flavor without the caffeine.
