If you’ve ever joined a fitness community or researched ways to make your workout more productive, you’ve likely heard about pre-workout supplements. And when so many athletes and gymgoers swear by them, you may wonder how they work. 

These supplements are made to improve your workout performance by giving you the energy, focus, and endurance needed to optimize training sessions. If you’re lifting weights, doing cardio, or training for a competition, the right pre-workout supplement for your lifestyle can make a difference. To help you decide whether to take a pre-workout, our guide will discuss what they are, how they work, and how to choose one. 

Why People Take Pre-Workout Supplements 

A pre-workout supplement, whether it’s creatine, caffeine, or a proprietary blend, is something you take before a workout to boost your energy and performance. Because the ingredients in them support physical and mental performance, people take them about 30 to 45 minutes before a workout. 

Besides the benefit of added energy, people take pre-workouts to push through fatigue, help them focus, and get better results. Whether your fitness goals include gaining muscle, burning fat, or both, pre-workout supplements can be a useful addition to your stack. 

How Do Pre-Workout Supplements Work?

Though there are several different compounds across various pre-workout blends, most of them have one of three functions. Firstly, they stimulate your central nervous system, making you feel alert and focused. Secondly, they increase blood flow to deliver more oxygen and nutrients to your muscles while exercising. Lastly, they help your body generate more energy during intense workouts. 

Altogether, these three effects make you feel energized, help you work out for long periods, and reduce fatigue during exercise. Now that we’ve gone over some of these benefits, here are the main ingredients in the best pre-workout supplements: 

Caffeine 

This is one of the most commonly-found ingredients in pre-workout supplements, with plenty of research supporting its benefits. Caffeine works by stimulating the central nervous system, triggering the release of adrenaline, and promoting dopamine and norepinephrine production for better mood and focus. This boost of stimulation makes you feel alert and ready to power through the workout.  

Research shows that caffeine improves exercise performance when consumed in doses of 3 to 6 milligrams per kilogram of body mass. That’s why it’s an ingredient in some of the most potent pre-workout supplements like LGXNDS Decipher. 

Creatine 

Creatine is an amino acid naturally found in the body that plays a role in producing ATP, the main energy source used during short intervals of intense exercise. So when you take creatine as a pre-workout supplement, it helps your muscles regenerate ATP faster, improving performance during strength training or HIIT. 

Consistently taking creatine will increase your strength during workouts by replenishing energy stored in your muscles. Pre-workout supplements with creatine, like LGXNDS Creatine Monohydrate Gummies, also help with muscle recovery after workouts, making them a great option for short-term strength and long-term muscle growth. 

Beta-Alanine

When you exercise, lactic acid builds up in the muscles, causing fatigue and soreness. Beta-alanine is an amino acid that buffers lactic acid buildup in your muscles during high-intensity workouts. It works by increasing carnosine levels in the muscles, which can delay lactic acid accumulation, helping you exercise for longer periods before feeling tired. 

Pre-workout supplements containing beta-alanine, like LGXNDS Decipher, increase your endurance, letting you push through high-intensity training without getting tired quickly. This makes it a good choice for activities that need sustained effort, like weightlifting, running, or cycling.  

L-Citrulline 

This is an amino acid that increases the production of nitric acid, a vasodilator, in the body. This means it helps expand blood vessels to improve blood flow, increasing oxygen and nutrient delivery to muscle cells during workouts. This results in effective performance and quicker muscle recovery after your training session. 

L-citrulline helps you achieve a muscle pump during resistance training, which gives your muscles a fuller, more vascular look. That’s why the best pre-workout supplements formulated for strength and endurance, like LGXNDS Creaflow, contain vasodilator compounds for muscle pump.    

Branched-Chain Amino Acids (BCAAs) 

BCAAs like leucine, isoleucine, and valine, are essential amino acids that play a role in your body’s ability to build muscle. During exercise, BCAAs prevent muscle breakdown, giving your muscles the necessary building blocks for recovery and growth. Supplementing your body with BCAAs using the right pre-workout can reduce muscle soreness and accelerate recovery after an intense workout. They’re especially useful during long workouts where you’ll lift heavy weights or do repetitive movements. 

Types of Pre-Workout Supplements   

You can divide the best pre-workout supplements for females and males into two categories: stimulant and non-stimulant. Stimulant pre-workout supplements are great if you need a significant boost of energy because they contain caffeine to enhance focus and performance. 

On the other hand, non-stimulant pre-workout supplements are formulated for people who are sensitive to caffeine or work out in the evening. Instead of containing caffeine, they focus on improving endurance, increasing blood flow, and supporting recovery without any jittery effects. 

Get The Best Pre-Workout Supplement For Your Needs

There’s no one-size-fits-all pre-workout supplement, so the best results will come from consistent use tailored to your needs. Once you’ve determined whether you want a stimulant or non-stimulant pre-workout, take it consistently to see how it’s affecting your workout. Keep in mind that not everyone will react the same way to a pre-workout, so you’ll need to use one formula for a few weeks to see if it aligns with your fitness goals. This allows your body to adapt, so you can determine whether to change the timing, dosage, or supplement altogether.
