10 Best Pre-Workouts For Weight Loss

If your workout goal is to burn fat and maintain muscle, you’ll know how difficult the process can be. Losing fat takes time, patience, and hard work. This can be frustrating, especially if you’re not seeing the results that you’d like. 

We can’t break the laws of thermodynamics, so if you want to lose weight, you have to burn more energy than you consume. This involves either eating less or burning more calories through your workouts.

If you’re eating less food, you may not be as energized to perform to your best in the gym, so you won’t burn as many calories as you want to.

If this sounds familiar, a pre-workout may be able to help. These efficient tools are packed with ingredients that can help you reach maximum efficiency while you train. As the name suggests, you take these supplements before your workout.

Depending on the one you go for, your choice may help you maintain muscle and lose weight simultaneously.

As there are so many pre-workouts to choose from, it can be difficult to know which one you should go for. To make this choice a little easier, we’ve listed the top 10 best pre-workouts for weight loss below.

We’ve also included a handy guide that explains what you should look out for when shopping for one of these supplements. You’re sure to find one that suits you in our list below!

Buyers Guide 

What is Pre-workout Used For?

Pre-workout supplements are used to give you energy while you exercise. These are usually taken around half an hour before a workout and can be in pill or powder form. Pre-workouts have various ingredients in them which are designed to maximize athletic performance. 

Best Pre-Workout Ingredients For Weight Loss

Pre-workout supplements can be full of different ingredients, but some of these are better than others, especially when it comes to weight loss. 


If you’re a coffee drinker, you’ll know how a cup in the morning can make you feel alert for a few hours. Coffee contains caffeine, a stimulant that’s popular within several pre-workout supplements.

Other than making you feel alert, caffeine also boosts concentration, improves reaction time, and athletic performance. This is great when you’re in the gym, as it helps you push through taxing workouts.

Better endurance means you’ll be able to work out for longer, whether you’re on the treadmill, at a fitness class, or in the weight room. 

Caffeine also has thermogenic properties that can help you lose weight too. Doses between 100 to 400 milligrams of caffeine can speed up your metabolism, effectively increasing the number of calories you burn. 

Caffeine can be a great weight loss tool, as long as you’re in an energy deficit. However, too much caffeine can be dangerous. We’ll get into the reasons why below, but be sure that you don’t exceed more than 400 mg of caffeine each day. 


This amino acid has fantastic effects. When you’re getting through a tough workout, beta-alanine helps to make you less tired as you go on. It increases your physical endurance which helps you perform better in the gym. 

Beta-alanine is converted into carnosine, a protein that lowers lactic acid buildup. Lactic acid is responsible for the soreness you get after a workout. Carnosine helps to reduce muscle fatigue, helping you get a few more reps in until failure.  

When you’re on a weight loss plan, you’re going to be consuming fewer calories. This can mean that there may be days when you lack the energy to get through a workout. Beta-alanine helps you train harder for longer, all without eating more and compromising your diet. 

Another bonus is that beta-alanine is responsible for the tingling sensation you get after taking pre-workout. Most people like this feeling, as it can act as a signal telling you when to start your gym routine. 

Citrulline Malate

Citrulline Malate is a powerful ingredient that helps you get the most out of your training sessions. When it is consumed, it turns L-arginine into nitric oxide. This compound helps to increase blood flow by dilating the blood vessels.

Increased blood flow means that oxygen and important nutrients can get to the muscles easier. As a result, your muscles will be less fatigued and your body will have more stamina, helping you perform better in the gym. 

As you exercise, your muscles will have a build-up of lactic acid and ammonia. As these substances increase, your muscles will start feeling worn out. This can stop you from getting through your workouts, which can be detrimental to your weight loss goals.

Citrulline malate relieves muscle soreness, helping you reach your maximum potential in the process. 

N-Acetyl L-Tyrosine

Also known as NALT, this substance works on the neurotransmitters in your brain, helping to reduce stress and improve concentration. 

Exercising hard increases stress levels and puts the body in a fatigued state. Pre-workout supplements with NALT help activate the thyroid, norepinephrine, dopamine, and epinephrine hormones. As a result, you feel calmer, less stressed, and in control of your actions. 

NALT also reduces brain fog, so you perform your workouts more efficiently and with purpose. This all helps you to lose weight and burn more fat. 

Pre-Workout Ingredients To Avoid

Pre-workout supplements are safe to consume, but that doesn’t mean that they don’t come without risk. If you want to add them to your fitness regimen, it’s important to look out for these potentially harmful ingredients. 

Too Much Caffeine

As stated previously, caffeine is one of the best pre-workout ingredients, especially when it comes to weight loss. However, an excessive amount of this stimulant can be harmful to the body. 

Too much caffeine can cause several side effects, including irritability, stress, and poor sleep. More seriously, caffeine can have adverse effects on the heart. Increased heart rate, high blood pressure, and heart attacks are all possibilities that come with consuming excess caffeine. 

In most cases, pre-workout supplements contain between 150mg to 300mg of caffeine in each serving. This is similar to the amount that’s within 1-2 cups of coffee. If you drink coffee on top of your pre-workout supplements, it’s important to check how much caffeine you’re consuming.

Most healthy adults shouldn’t exceed 400mg of caffeine each day. If you go over this amount, try to cut back gradually until you’re within safe limits.

Sugar Alcohols and Artificial Sweeteners 

Pre-workouts are often full of sugar alcohols and artificial sweeteners. These ingredients are popular as they provide appealing flavors, like tropical fruit and cola, without extra calories. 

This may sound great, but sugar alcohols can cause intestinal issues, like bloating, gas, and diarrhea. These side effects may also be possible after consuming sweeteners. For instance, sucralose is known to cause intestinal discomfort if consumed in excess. 

We’re focusing on weight loss here, so you may still want to go for brands that include these flavor-enhancing ingredients. Other brands that don’t use these will often use traditional sugar instead.

These products are less common, but the sugar adds lots of calories which can sabotage your fitness goals. 

It’s best to check the label and see how many sweeteners are in your product. Try to avoid formulas that have large amounts of artificial flavorings in them. If it’s too difficult to find these, test your product out first by taking a small amount of the supplement.

Take note of how your body reacts. If you don’t notice any side effects, increase your intake and work up to the recommended dosage. 

Proprietary Supplement Blends

The FDA states that ingredients in any product need to be listed in weight order. The ingredient with the greatest amount should be listed first, then they should be labeled in descending order. 

Proprietary blends are a product that contains several substances in various quantities. It’s a way for companies to hide any cheap ingredients and low doses within their product. This helps them to cut costs and increase their profits while selling ineffective items.

It also hides any unsafe or risky substances that are in their supplement.

It’s important to know what dosage of each ingredient you are taking. If you see ‘proprietary blend’ listed on the label, your supplement probably lacks a sufficient dosage or contains hazardous ingredients.

Always check the label thoroughly and find out what ingredients are in your pre-workout before you buy them. 

Frequently Asked Questions

How Much Pre-Workout Should I Take For My Weight?

Pre-workout supplements all have different amounts of ingredients, so there isn’t one suitable amount that covers them all. Always follow the directions given by the supplement that you take. One of the most common ingredients in pre-workout is caffeine.

Most healthy adults can consume 400 milligrams of caffeine each day. It’s best to ensure that your supplement doesn’t make you go over this recommendation. 

Does Pre-Workout Have Calories?

Pre-workout supplements generally don’t have a lot of calories, but they often use sweeteners and sugar alcohols to lower the calorie count. Some brands don’t use these artificial ingredients, but they may have a higher calorie count as a result. 

Is It Bad To Take Pre-Workout Every Day?

If you take pre-workout every day, your body may start becoming used to its effects. Over time, you may need to take more pre-workout to get the desired result. To avoid this, some gym enthusiasts recommend taking these supplements in cycles. They take 6-8 weeks off so that the body can readjust again. 

Can I Take Pre-Workout On An Empty Stomach? 

The majority of pre-workouts are safe to take on an empty stomach. However, consuming these supplements without any food prior means that the substance enters your bloodstream quicker.

If you have low blood sugar issues, like hypoglycemia, you may find that training on an empty stomach will make you feel weak. Taking pre-workout on top of this may exacerbate these symptoms. If you suffer from low blood sugar or digestive issues, it’s always best to have a snack a few hours before your workout. 


There you have it! These are the top 10 pre-workout supplements that can help promote weight loss. Do remember that it doesn’t matter what pills and potions you take, you won’t lose weight unless you’re in a calorie deficit.

That being said, as long as you’re following a controlled diet plan, pre-workouts can be an amazing tool when it comes to fat loss. The majority of these energy enhancers have a lot of caffeine in them, so if you have a low tolerance, work up to a full dose slowly.

Otherwise, have fun training!
