Need some energy before the gym? Here are the 6 best pre-workouts

Top 6 pre-workout supplements: What you need to know and which one to buy

While you don’t need pre-workout to build muscle, it can be helpful if you require an extra ‘push’ to get through your workout if you’re a bit more fatigued one day or if you’re in a calorie deficit. Pre-workout supplements include ingredients that supply energy, help you push harder, improve focus, and can help your body more easily build muscle and recover from your workouts.

We examined products for effective formulas, caffeine, testing, user experience, and overall safety to find the best pre-workout supplements to help support your workouts and fitness goals. You’ll also find a guide to the products that can give you a natural pre-workout boost.

What to Consider

Caffeine

Caffeine is the primary stimulant in most pre-workouts. Doses typically range between 150mg and 300mg per serving, but more isn’t always going to give you the better workout experience – especially if you’re sensitive to caffeine jitters or fond of a late-night workout. While caffeine is not needed for a workout, the compound might improve your performance and focus. Research has found that consuming caffeine within 60 minutes of your workout can improve aerobic and anaerobic running capacity, strength, and power.

Research published in Food and Chemical Toxicology cited that 400mg of caffeine a day is the upper limit for adults. What does this mean to you? One cup of instant coffee contains 60-80mg of caffeine, but high street flat whites typically contain between 120mg and 160mg. Some pre-workout brands spill over the recommended daily dose, so pay close attention to the packaging.

Considering a stim-free or caffeine-free pre-workout? We did a little investigation into this product category ourselves, and found them to not be as effective. You would likely be better off taking the supplements found in stim-free versions like beta-alanine and creatine in individual doses.

Other Ingredients

Pre-workout supplements also like to advertise all the other stuff they include on top of the caffeine. Citrulline for blood flow. Beta-alanine for muscle fatigue. Creatine for creatine’s sake. A lot of the products making these claims often don’t have enough of the stuff to matter. For example, some products claiming to contain creatine only have a single gram of it, which is not even a quarter of your recommended dosage. It hardly seems worth it. Optimum Nutrition’s Gold Standard Pre-Workout at least has 3.3 grams, a much more reasonable offering. For the more esoteric ingredients, there isn’t a whole lot of science behind how they combine in a pre-workout.

As sports nutritionist Matt Lovell points out, there are definitely some ingredients included in pre-workouts that you should actively avoid, too. ‘I would say any speed cousins, amphetamine cousins. Some pre-workouts basically contain ecstasy. Or close to it,’ he says.

Safety

For most men, pre-workout is a safe supplement to take, but even at the safe end of the spectrum, its side effects can still cause jitters, itching and interrupted sleep, which are harmless but still uncomfortable. Our advice: if you’re new to pre-workout, go for half doses to begin with and see how your body reacts.

To err on the side of caution, it’s also a good idea to choose a supplement that has been third-party tested, which will ensure that each batch has been tested to ensure it contains exactly what it the packaging claims, and that it is free from banned substances or other contaminants.

How We Selected

To help you find the best pre-workout for energy, endurance, and strength, we enlisted a panel of sports nutritionists to put a range of market-leading products to the test as part of our 2024 Sports Nutrition Awards and 2025 Sports Nutrition Awards.

They assessed each pre-workout supplement based on the quality of ingredients, nutritional make-up and formulation. Judging was extremely stringent and only the top-rated pre-workouts that really impressed were put forward for further testing back at Men’s Health HQ.

Our panel of testers, including editors, then rated each best pre-workout on flavour, texture, aroma and ease of use. We also tested them over a period of a few weeks to see how they impacted athletic performance. After all that, feedback was analysed, and final scores were awarded. The products above with the esteemed Sports Nutrition Awards logo are our winners and have passed our rigorous assessments.
