What Is A Pre-Workout Supplement?

A pre-workout supplement helps you achieve optimal results in training. It can also help push an athlete beyond his or her limits. The strongest pre-workout may contain one or more ingredients that will boost your energy, focus, and strength.

Pre-workouts can be described in two classes:

Top 8 Strongest Pre-Workout Supplements For High Energy 2018

1. Pre-workout Supplements With Creatine

Creatine is a popular ingredient in sports performance products. This ingredient can help increase your strength and power by synthesizing adenosine triphosphate (ATP) at a quicker rate. When you drink more water, you can achieve a more defined appearance with thicker muscles.

However, creatine may cause water retention and weight gain if you take too much. You also become more prone to dehydration since this ingredient prevents the absorption of water into your cells.

2. Creatine-free Supplements

This type of supplements is formulated without the creatine ingredient. This is also categorized into two types: natural pre-workouts and proprietary blends. Obviously, the natural variety uses natural ingredients, like vegetable sources, caffeine, and vitamin B12.

Proprietary blends, on the other hand, use different ingredients. Instead of using clinical doses of ingredients, they group the ingredients together hoping that consumers don’t notice. The lack of transparency gives a strong doubt to consumers and makes me feel iffy.

Ingredients That Power The Strongest Pre-Workout Supplements

Top 8 Strongest Pre-Workout Supplements For High Energy 2018

Amino Acids (Taurine And/Or Tyrosine)

Amino acids are the building blocks of proteins which help deliver oxygen to your muscles. This result to less muscle damage after a strenuous workout. When mixed with other ingredients in a pre-workout formula, they can boost your recovery time between workouts.

Taurine is necessary for muscle contractions and other physiological processes. When taken before a workout, every rep will become more effective and powerful. Tyrosine works almost similarly but it can also help you feel more focused and alert.

Nitric Oxide (NO2)

Nitric oxide might be one of the most famous ingredients found in the strongest pre-workout supplement. Its main function is to decrease the amount of lactic acid your muscles generate as you workout. Keep in mind that lactic acid can bring a quick end to your session when they’re produced by your muscles.

This ingredient increases the time in pushing yourself, which enables you to get the most of your workout. Best of all, it helps prevent fatigue and post-workout pain, enabling you to have a quick recovery.

Betaine Anhydrous

If you wish to increase your total load, then look for betaine anhydrous ingredient. This ingredient is necessary to deliver oxygen to your muscles at an improved rate. As a result, you’ll gain more strength and boast better protein synthesis.

Vitamin B12

This vitamin is essential for the production of new red blood cells, which are important for the delivery of oxygen and nutrients. According to the study of the University of Maryland Medical Center, taking a high amount of vitamin B12 may give you more energy and less fatigue. Just make sure that you don’t take it in its pill form because it will reduce its bioavailability.


Another potent ingredient that you should look for in a strong pre-workout formula is caffeine. This ingredient helps uplift your mood and makes you feel more alert during a workout session. Just make sure that you don’t take too much because it can increase cardiac activity.

What To Look For

Top 8 Strongest Pre-Workout Supplements For High Energy 2018

Trusted And Tested Ingredients

The best pre-workout supplement should only contain high quality and clinically proven ingredients. If you don’t like to have jitters or any side effects, opt for all natural ingredients.

Stay away from high amounts of creatine because it may cause potential risks such as kidney damage, dehydration, and weight gain.

It’s also important that the brand presents a full ingredient transparency. This is to make sure that you know the exact amount of ingredients you’re consuming. To spot any contaminants and ensure the integrity of ingredients, the best brands use credible facilities to conduct a third party testing.

Money Back Guarantee

A money back guarantee or satisfaction guarantee simply means that you’ll get a refund if you’re not satisfied with the quality of the product. This will give you peace of mind when trying a new pre-workout supplement. Just make sure that you read the terms well so you won’t have problems when returning it.

Amazing Flavor

You might think that this a trivial matter but the flavor can make a big difference. You’ll have more motivation to drink the pre-workout supplement if it tastes good. Many brands are made with different flavors, like strawberry lemonade, fruit punch, and mixed berry blast.


As shown above, the strongest pre-workout supplement is the Relentless Pre-Workout Supplement Powder. This creatine-free formula is made of high-quality ingredients to boost energy and mental focus such as caffeine, nitric oxide, and vitamin B12. It’s made of trusted and tested ingredients with full transparency.

Relentless also offers a money back guarantee in case you’re not satisfied with the quality. Aside from getting a high surge of energy, you’ll enjoy its amazing taste. I choose Relentless over its other competitors because it contains the most potent stimulants at a reasonable price and it’s tested with a third-party facility.
