They generally contain stimulants and nutrients that increase stamina, energy, and focus.

Pre-workouts have various ingredients

  • Caffeine – Studies suggest that caffeine aids in weight loss. It increases the number of calories your body utilizes. It can also give you additional energy to get through workout sessions and improve exercise performance.
  • Creatine – This is a common ingredient in pre-workouts. It can improve anaerobic endurance, help with building muscle, increase strength, and lessen muscle soreness.
  • Nitric Oxide Precursors – These compounds, such as citrulline malate, increase nitric oxide levels. These are released by the body to promote healthy blood flow and relax blood vessels lowing blood pressure.
  • Beta-Alanine – This nonessential amino acid is used by the body to generate carnosine. This prevents lactic acid accumulation, lowering muscular fatigue, and can help you to complete a few extra reps in a set.
  • Branched Chain Amino Acids (BCAAS) – These essential amino acids reduce protein breakdown in the muscles and also aid in fueling the muscles. They include valine, leucine, and isoleucine.
  • Micronutrients – Pre-workouts can have various B-vitamins, chromium, vitamin C, vitamin D, and magnesium. These micronutrients improve your overall wellness and energy levels.

Can Pre-Workout Supplements Make You Gain Weight?

Pre-workouts typically boost performance for exercise. Some of their ingredients are also proven to improve muscle growth and recovery. Firstly, while these supplements might have sweet-tasting flavors, they rarely contain sugar.

Pre-workouts can have different effects depending on the user…

Some users gain weight quickly when taking them instead of losing weight but this isn’t necessarily body fat weight.

Lifestyle is a big component when it comes to changes in weight and there are many factors that can cause changes as side effects.

By looking at pre-workout formulas, we can guess if weight gain is likely. These supplements have two essential components that affect this field: creatine and caffeine.

These ingredients improve your stamina and energy.


Caffeine is one of the most common stimulants for the body. It can improve your mental focus, reduce fatigue, physical performance, and energy.


These benefits can be great for strength training or exercise. Caffeine can help you lose weight by increasing your fat metabolism during exercises. It also acts as a diuretic, meaning that it causes the body to shed water weight.

This ingredient can complicate things a little… While creatine can improve your performance during workouts, it can boost your muscle growth. Taking a pre-workout supplement with creatine can make you increase your lean muscle mass, increasing your body weight.

It is recommended to drink plenty of water when taking creatine regularly.

Creatine is a muscle osmolyte and supports cell volumization. It increases this cell volume by causing water to be pulled into the muscles.

So when you consider any increase in body mass (regardless of whether it is lean muscle mass, water or fat) as weight gain, you can say that creatine can make you gain weight.

People respond to creatine differently. While others gain weight when they take it, others don’t gain lean muscle mass. Most only see slight variations in weight.

Getting professional advice before taking these products is beneficial. Especially if you are already taking supplements or consume a lot of caffeine. You may experience a spike in your caffeine intake levels. This increase can exceed your body’s caffeine tolerance levels.

Factors That Contribute To Weight Gain

Some factors that may contribute to your weight gain when you regularly consume a pre-workout include:

Water Retention

You may lose a lot of water after an exercise. For example, some people lose up to 15 pounds because of the water they lose after workouts.

This loss can cause a significant reduction of body mass, as water makes up 70–90% of one’s body weight.

Your body mass varies with your water content. Taking pre-workouts can also affect your water content mainly due to the ingredients mentioned above (creatine and caffeine). Some people can also have naturally high water retention.

This can be particularly true for females. So the side effects of these supplements may be unpredictable.

Scale Mass

This term refers to the mix of muscle, air, fat, urine, blood, tissue, and neutral matter in one’s body. Intense workouts facilitated by pre-workouts can increase your scale mass by up to 15%, making you think the pre-workouts caused the increase in weight.

The weight gain results from various factors, such as inflammation, post-workout hydration, and intestinal by-products.

Can Pre-Workout Supplements Help You Lose Weight?

So we know that Pre-workouts can improve your performance during your exercises. An indirect benefit is that you can leverage this improvement to have intensive workouts and help with weight loss. The thermogenic effect created by some ingredients can also aid in weight loss.


If you are serious about managing your weight, for example, you need to get into a particular weight category for a competition, here are a few considerations to help achieve these objectives:

Use Pre-Workout Supplements Without Creatine

Some pre-workout drinks don’t have creatine. Find the products without this ingredient to increase your chances of losing weight. If do decide to drop the creatine, remember that it can stay in your body for a long time, so be patient.

Manufacturers list their ingredients on their product’s containers. Read them to ensure the one you buy doesn’t contain creatine. Some fitness enthusiasts have a cup of coffee to avoid the other ingredients.

Monitor The Supplements Effects On Your Body

You don’t have to change your supplements if you like them and they contain creatine. Monitor their effect on your body to determine the best course of action.

Some people can take pre-workouts with creatine and lose weight efficiently. If your pre-workouts help you lose weight, it’s a good idea to continue their use.

Consider other alternatives if they don’t help you get the results you desire.

Count Your Calories

Your calorie intake will have the most effect on your weight in the long term. Consume fewer calories than those recommended for someone with your build to lose weight. Most pre-workout formulas have low-calorie content and don’t contain sugar, so that should not be a concern.

Monitoring your calorie intake can ensure you lose weight regardless of the pre-workouts you take. It can also help you pinpoint the cause of any weight you gain. You won’t attribute increases to your pre-workouts when they aren’t responsible for them.


Pre-workouts can be excellent products for weight loss if you use them well. Some considerations can help you with this objective, such as their ingredients and effects on your body.

Finding the right pre-workout will improve your performance during exercises and help you lose weight.
