10 Strongest Pre-Workout Supplements 

Strongest Pre workout Supplements - WLFH Featured Image

There are lots of different supplements you can use that will help make your workouts more productive. Popular products include protein powders, creatine, and amino acids. However, one of the most widely used is pre-workouts.

Pre-workouts boost your energy so you can train longer and harder than usual. Longer, harder workouts mean better results and faster progress. Formulations vary from manufacturer to manufacturer, and some pre-workouts are stronger than others.

Mild formulas are ideal for pre-workout newbies. They are weaker, but you’ll still feel some noticeable effects because you aren’t used to the product. But, if you use a pre-workout regularly, you’ll probably become accustomed to the ingredients and will need something more potent to boost your energy.

The good news is that there are plenty of extra-strong pre-workouts explicitly designed for more experienced users. So, if your pre-workout is no longer producing the results you want, these are the supplements for you.

Be warned, even if you are a regular pre-workout user, these supplements may cause mild side effects, such as tingling, reddening of the skin, and even jitteriness and tremors. However, such side effects are temporary. So, if you are looking for the most potent pre-workout supplements, try one of the products in this review!

FAQ’s 

Do you have questions about pre-workout supplements? We’ve got answers! Read on for the most common pre-workout FAQs…

What are the most common ingredients in pre-workout?

All pre-workouts are different, but most contain similar ingredients, albeit in differing amounts. The most common pre-workout ingredients and their basic functions are:

Caffeine – a potent and widely-used stimulant, caffeine has been shown to increase energy, ward off fatigue, and enhance fat burning. However, in large amounts, it can also cause unwanted side effects, including muscle tremors and insomnia. Not all pre-workouts contain caffeine, but most have at least a few cups of coffee worth.

Beta-alanine – this pre-workout ingredient helps increase workout capacity by reducing the fatiguing effects of lactic acid. It’s also responsible for most of the tingling and itchiness associated with pre-workout use.

Creatine – creatine is a widely used supplement that increases intramuscular stores of ATP, so you’ve got more energy for exercise. Creatine may also speed up recovery and enhance muscle growth. On the downside, it may cause water retention, which is why some users prefer creatine-free pre-workout supplements.

B-vitamins – the B vitamins play an essential role in the breakdown of carbs for energy. So, while they don’t have an energizing effect themselves, the B vitamins mean you can access your onboard energy stores more efficiently.

L-citrulline – this amino acid increases levels of nitric oxide in your blood. As a result, your blood vessels open up (vasodilation) to allow for easier and more plentiful blood flow.

This increases your energy while promoting a powerful pump effect that most bodybuilders and weightlifters welcome. On the downside, L-citrulline can cause skin flushing and redness.

BCAAs – short for branched-chain amino acids, BCAAs are a part of protein, and your body uses them for energy and muscle growth, and repair. Pre-workouts with BCAAs may help reduce muscle breakdown and speed up recovery.

However, if you eat a lot of protein, you probably have enough BCAAs in your diet already, and getting more will be of little benefit.

What are the benefits of pre-workout?

Recovery on sportsPre-workouts are formulated to help you:

  • Exercise harder than normal
  • Exercise longer than normal
  • Increase your focus and determination
  • Recover faster from your workouts
  • Burn more calories per workout

These factors combine to produce more effective workouts so that you get better results in less time.

What are the side effects of pre-workout?

While pre-workouts are mainly safe to use, they can cause side effects that may be less desirable. The main side-effects of pre-workouts include:

  • Muscle tremors and anxiety
  • Increased heart rate
  • Tingling and redness of the skin
  • Stomach upsets

These side-effects can often be avoided by using a smaller amount of pre-workout and only increasing the size of your dose as you get used to the effects of the ingredients.

Man Taking His Pre-workoutWhen should I take pre-workout?

Most pre-workouts are formulated to start working quite quickly and usually last 2-3 hours.

As such, you should take your supplement 15-30 minutes before your workout.

That said, pre-workouts usually have instructions for use, and these should be followed to ensure you get the most from your chosen product.

Bottom Line

Energy is a valuable commodity, and everyone has days when they don’t have enough. Maybe you didn’t sleep as well as usual, or perhaps have been working harder than normal or have been feeling stressed. But, regardless of the cause, a pre-workout will ensure you have the get-up and go you need to power through your next workout.

That said, if you use the same pre-workout for more than a few consecutive weeks, it will start to lose some of its potency. Your body becomes accustomed to the ingredients, and you won’t feel as energized. Yes, you could use a larger dose, but then your product won’t last as long.

One of the best ways to ensure your pre-workout always delivers the results you want is to upgrade your supplement and buy something a little more powerful. In most cases, that’s all you need to get crank your energy levels to the max.

But, with so many pre-workouts to choose from, knowing which product is best can be hard. After all, the ingredients are often very similar, and most pre-workouts have the same basic effects.

Cut through the marketing hype with our review of the 10 strongest pre-workout supplements. Each one has been formulated to boost your energy and improve workout performance. Whatever you are looking for, you’ll find it in these reviews.
