Choosing the right supplement for your workout routine can be a daunting task. With so many products on the market, it’s hard to know which one is right for you. If you want to know the difference between pre workout vs. protein powder, keep reading to find out!

Pre workout vs. protein powder: Both are useful for different purposes. Pre-workout usually contains caffeine as a stimulant and other ingredients which help to improve physical performance and increase the training volume. Protein powder is a concentrated source of protein necessary for recovery, muscle growth and minimizing muscle loss during cutting.

Pre workout vs. Protein Powder

What Is Protein Powder?

If you don’t understand the difference between pre workout and protein powder, let’s take a quick look at these two types of supplements.

Protein powders are deservedly one of the most popular supplements in the world of fitness and sport. It’s made by extracting protein from sources such as milk (whey and casein protein powders), eggs, soy, pea and other sources in a powdered form. Not only is protein powder convenient for anyone looking to increase their protein intake, but it also provides some important micronutrients. For example, whey protein contains a significant amount of calcium per serving, casein contains a huge amount of calcium, and pea and hemp proteins contain significant amounts of iron.

Protein powders greatly facilitate the task of consuming the needed amount of protein, saving time for food preparation. If you find it difficult to eat the needed amount of protein from whole foods, a serving or two of protein powder will make it easier.

Sufficient amount of protein helps to build and maintain muscle mass, as well as minimize its loss during weight loss phase. If you’re bulking, you can get lots of protein without feeling like you can’t eat any more food. If you’re cutting, a protein powder with zero to minimal fat and carbohydrates may be your most convenient source of a concentrated serving of protein with the fewest calories possible.

You can make protein shakes and smoothies, add the powder to oatmeal or other cereal, make protein pancakes, and even bake with it. This versatility makes it an excellent choice for busy fitness enthusiasts looking for a quick and easy protein fix or athletes who just need a high amount of protein to effectively recover and grow muscles from hard training. So if you’re looking to increase your protein, consider trying some protein powder!

What Is Pre-workout?

Pre-workout is a supplement that consists of ingredients to give you the energy boost, increase overall athletic performance and focus through tough workouts. The key ingredient in pre-workouts is caffeine (excluding caffeine-free versions), which provides a stimulating effect. Additional ingredients are most often beta-alanine, creatine, as well as l-citrulline, betaine and other components.

However, this is the kind of supplement that makes sense to use after you’ve passed at least the beginner stage in training. Before you buy your first pre-workout, you should already build up a significant amount of muscle mass, strength and generally achieve a good level of physical fitness.

When you reach a training plateau or your progress will decrease very much (and this is provided that your nutrition, training program and recovery is already optimized), then it makes sense to think about the first purchase of a pre-workout. What cannot be said about protein powders, which can be used even by people who do not engage in fitness or sports at all.

Pre Workout vs Protein Powder

In order for you to better understand the difference between the two types of supplements, we will now look at some of their characteristics.

Processing of Protein Powder vs Pre Workout

Depending on the raw materials used for the production of protein powder, these products are of animal or plant origin. The most popular protein powders of animal origin are whey and casein. For example, whey protein is obtained in the process of cheese making by adding enzymes to milk that separate whey from the casein part. Next, the whey goes through the processes of filtration and drying to form a powder.

For the production of plant based protein powders, the initial raw materials are cleaned of the outer shell, grounded into a fine flour, and under the action of enzymes, the protein part is separated from the starch. Depending on the specific source (hemp, pea, rice), production methods differ. However, in the final result we get a powder form of plant-based protein.

For the production of pre-workouts, powder forms of individual ingredients, which are produced from different substrates, are mixed into one product. For example, caffeine can be produced either by extraction from natural sources (for example, from kola nut, cacao bean or guarana berries), or by chemical synthesis from urea and chloroacetic acid (however there is no chemical difference between synthetic and naturally sourced caffeine). All the necessary components of pre-workout can be blended in needed amounts to create the required formula. Additionally, most pre-workout supplements have fruit-based flavors, which are added using various natural and artificial ingredients.

So, is pre workout the same as protein powder? If you were looking for an answer to this question, now you know for sure that these are completely different types of supplements.

1. Average Macros per Serving

Protein Powder

Generally, protein powders contain 20-25 grams of protein (although vegan powders often contain 15-20 g), with 0-5 grams of fat, 0-10 grams of carbs (vegan versions usually contain closer to the upper range), and 100-160 calories per serving.


Pre-workouts are fat-free, most are carb-free, although some may have a few grams of carbohydrates. Does pre workout have protein? No, but it may contain amino acids, such as BCAA or tyrosine, which still have calories.

In general, pre-workouts are not the type of supplement that contains a significant amount of calories per serving. However, if you are in the final stage of cutting and meticulously counting every calorie, you should still consider the calories you can get from pre-workouts that contain a few grams of carbohydrates and amino acids.


2. Price Range

Protein Powder

Each serving of protein powder will cost $1-2, with the price going up or down depending on the source (vegan or animal-based), type of protein (concentrate or isolate), and specific brand. For example, whey protein isolates are more expensive than whey protein concentrate due to additional filtration steps and a higher percentage of protein in relation to the total caloric content per serving.

That said, there are plenty of great-tasting and reasonably-priced options out there if you take the time to shop around.


Depending on the brand that you choose, the overall ingredients breakdown, dosing of each ingredient and availability of third-party certification, the price per serving can range from as little as $0.6 to $2.5.

Protein vs. Pre-workout: Summary

Both supplements have different purposes and are therefore not interchangeable, so there really shouldn’t be a debate between pre workout and protein powder. In fact, you can use both supplements at the same time, although this requires further explanation.

In general, protein powders can be used by almost anyone, at any time of the day. What can not be said about pre-workouts. This type of supplement should be used by people with regular training experience, good caffeine metabolism, and only before training (preferably in the first part of the day, if we talk about caffeinated products).

Also, most studies looking at pre-workouts lasted less than 8 weeks, so the long-term safety profile of this type of supplement is still unknown. For this reason, it is better to follow the path of minimizing risks and take breaks when taking pre-workouts. On the other hand, protein powders can be used on a regular basis, especially if we’re talking about products from reputable brands that submit their protein powders to third-party testing.

Pros and Cons of Pre-workout


  • Gives a stimulating effect and a boost of energy
  • Improves overall athletic performance and muscular endurance
  • Contribute to increasing strength, power output and lean muscle mass
  • Enhance the pumping effect of training if it contains certain ingredients in the right dosage
  • Increase alertness and mental focus

Could be better:

  • Not suitable for non-exercising individuals and beginners in training
  • Can cause negative side effects due to a large dose of caffeine
  • May cause a tingling sensation from a large single dose of beta-alanine (harmless, but uncomfortable feeling)
  • Has only been studied in short-term trials (long-term effects and safety still unknown)
  • Many pre-workouts contain a large number of additional ingredients that do not have scientific support, but add to the cost of the supplement
  • As a type of supplement pre-workouts contain more potential risks to consumers than protein powders

Pros and Cons of Protein Powder


  • Convenient way to increase the amount of protein in your diet
  • Saves time for preparing high-protein food
  • Helps build muscle mass and maintain it during cutting
  • Can be used at any time of the day and on a regular basis (without need to cycle) as a part of well-balanced diet
  • As a type of supplement have much better safety profile than pre-workouts

Could be better:

  • Does not have a stimulating effect (unlike a pre-workout)
  • Can be unpredictable in terms of gastrointestinal tolerance

Pre Workout vs. Protein Powder: When to Use Each

We’ve discussed the difference between pre workout and protein powder, and now we’ll go over when you should be using either supplement.

1. Pre-workout:

If you have been training regularly for a long period of time, have achieved results but stopped progressing and want to break through a training plateau, then you may want to try a pre-workout. They should be taken approximately 30-40 minutes before training.

However, consider your caffeine sensitivity and consult a doctor before buying your first pre-workout.

2. Protein Powder:

Protein powders can be used as an additional source of protein regardless of your training experience. If you want to add another serving of protein, or save time preparing a protein part of a meal, or have another option for a high-protein snack (for example, besides Greek yogurt), this is your choice! You can add protein powder to porridge or baked goods, and also use it in the form of a protein shake or smoothie.

Does Pre-Workout Have Protein?

Is Pre-Workout The Same As Protein Powder?

No, they are entirely different supplements with different purposes. Pre-workout gives you the energy boost and improves athletic performance during workouts, while protein powder helps cover daily protein needs.


To wrap up, both pre workout or protein powder can be useful supplements, although they serve different purposes. A pre-workout is a specialized sports supplement which is used only before training, while a protein powder is a convenience supplement, which is used at any time of the day and just helps cover the daily needs of protein.
