Working out takes a lot of energy, focus, and muscle power. A good meal with some carbs before you exercise can be a good energy booster, but there is an entire industry based on getting yourself ready for an intense workout. Here we will explore the best pre-workout supplements for almost every situation and training style.

Pre-workout supplements have expanded from just a few options about a decade ago into a massive sprawling industry full of hundreds of different options, many of which are specialized for extremely specific needs. With all the diversity in the market. It can be difficult to decide which option is best for your set of circumstances.

Which supplement you need really depends heavily on the type of workout or exercise you are about to engage in. For some, a simple caffeine drink will do the trick if you are just going for a quick jog for a few miles around the neighborhood, while others will need a balanced intense supplement that sustains your body for hours. In this guide, we look at the best possible pre-workout supplements for many different situations.

Best for Weight Loss- RSP AminoLean – All-in-One Pre Workout, Amino Energy, Weight Management Supplement with Amino Acids, Complete Preworkout Energy for Men & Women, Fruit Punch, 30 (Packaging May Vary)

Our Rating: (4.5/5)

RSP AminoLean is designed to help you manage your weight and provide energy for your workout as well. Notably, this product has a massive number of positive reviews (over 15 thousand) and it is extremely popular. It is one of the few supplements of this type that specifically claims to help with body weight. It contains:

  • L-Taurine
  • Beta-Alanine
  • L-Leucine
  • L-Isoleucine
  • Calcium Silicate
  • Acesulfame
  • Malic Acid
  • Gum blend
  • Green tea extract
  • And many more

This pre-workout drink has the most ingredients of any on this list, probably due to the weight loss factor. The ingredients listed above are just some of them. It also contains artificial flavors and colors as well, so it is certainly not the most natural option here.

It is effective at what it aims to do. Each serving contains 125 Mg of Caffeine which is far less than some of the other options, but the caffeine is cleaner, sourced from green tea extract. It gives you a nice energy boost without the nasty crash at the end that some other caffeine sources can do.

RSP Aminolean also contains essential amino acids for helping you to recover faster after an intense workout. Notably, this supplement has no sugars no carbs, and no calories, which is unique in this space!

Pros

  • Good for energy and weight loss
  • No carbs or sugars
  • Contains essential amino acids
  • Good for post-workout recovery

Cons

  • Not the most intense stimulant
  • Has a lot more ingredients than most

Conclusion

If you need a pre-workout drink that will also help you lose and manage body weight, this is a good choice for you. It is designed especially for the management of weight and will also help you lose weight. It has no carbs, calories, or sugars and will help you recover after an intense workout or prepare you for a new one. It has more ingredients than I would like to see, but it is not just an energy supplement it is also for weight loss.

Best for Early Morning- Optimum Nutrition Amino Energy – Pre Workout with Green Tea, BCAA, Amino Acids, Keto Friendly, Green Coffee Extract, Energy Powder – Strawberry Lime, 30 Servings

Our Rating: (4.5/5)

With so many options out there in the pre-workout drink world, it is hard to know which one is going to be the best first thing in the morning. Not everyone is a morning person, and some supplements may be much too strong (or too weak) for that early in the day. Optimum Nutrition makes this Amino Energy supplement that seems exactly right for early morning workouts.

Optimum Nutrition is a well-known supplement brand that has been in business for years and has a good reputation. Amino Energy is popular and has over 11 thousand positive reviews already. It comes in a handful of flavors and contains:

  • Amino Blend
  • Citric Acid
  • Natural and Artificial Flavors
  • Malic Acid
  • Silicon Dioxide
  • Energy Blend
  • Calcium Silicate
  • Sucralose
  • Gum Blend

The label on the bottle will explain what is in the ‘amino blend’ and the ‘energy blend’ if you want to get all the specifics. There are only 5 to 10 calories per service and 100 mg of caffeine per serving as well. This supplement is designed to be used multiple times a day if needed, unlike some that are very intense and the effects last all day.

Amino Energy is best for the morning because it’s plenty of energy but it’s not so intense that it is going to be distracting.

Pros

  • Can be used multiple times a day safely
  • Pleasant taste
  • Not too intense
  • Low calorie
  • No sugar

Cons

  • Need to use multiple times a day (not all-day strength)
  • Small container

Conclusion

This supplement is the perfect solution for you if you are a morning workout person. It is not going to keep you jacked all day like many of the more intense options in this list, but it is plenty of caffeine to get you going. It is not awfully expensive, but the bottle is smaller than most in this category. If you like it, you may end up having to buy several bottles for a month due to the size and strength being mild.

Best for Vegans- RSP Vegan AminoLean – All Natural Preworkout with Vegan BCAAs, All-In-One Amino Energy, Weight Management, Recovery, and Focus, 25 Serv, Cucumber Lemon

  • Organic tapioca polymers
  • Stevia
  • Silica
  • Weight management blend
  • Natural energy and focus blend
  • Citric acid

For more information on the ‘blend’ ingredients, you can consult the bottle. It is created mainly from fermented tea leaves guarana and organic matcha. These are all good ingredients, matcha is one of the more popular styles of green tea in the world!

It has a comprehensive blend of vegan amino that will boost your performance and aid in muscle repair and growth as well. This is a versatile supplement that can be used as a coffee replacement or a pre-workout drink or both.

Pros

  • Tastes great
  • Vegan
  • Made from all-natural ingredients

Conclusion

RSP Vegan Aminolean is a great supplement if you are a person who is trying to get healthier and does some exercising daily. It is not designed for the hardcore muscle builder, but more for the normal person looking for a vegan supplement that will deliver clean healthy energy and muscle growth/repair assistance.

Types of Pre Workout Supplements

Pre-workout supplements are all remarkably similar in the way that they are meant to affect your body. However, they do come in a few different forms. Each different form is there to match your needs. The 3 forms you can currently find them in are:

  • Powders
  • Gummies
  • Pre Mixed

Powders

Powders are first because they are the most plentiful in the marketplace. There are hundreds of powdered pre-workout drinks. This is the most popular form because it is easy to make (just add water) and powder is not very heavy so it is easy to ship and store for the manufacturer.

With powders, many people like to purchase a special bottle just for mixing the drinks on the go. There is even a whole category of them designed just for pre-workout mixes. There are as many flavors as there are powders in this category. Some of the most common are blue raspberry, watermelon, and lemon/lime.

This type of supplement is loved by many, it is a familiar format in the fitness world. People are already used to their protein powders and nutritional supplements and weight loss shakes, so it makes sense for these to come in powders.

Gummies

Pre-workout gummies are getting more popular, but they are not nearly as popular as powders. They come in similar packaging mostly, though some do come in more of a traditional candy-style package. Some look like an ice cream container. They come in the form of gummy bears or worms or simple squares in some cases.

They are similarly priced to the powders, ranging from about ten bucks for a smaller bottle up to about 30 bucks for a large container. Some high-end gummies go for even more than 30 bucks. They have similar flavor schemes as well with the typical blue raspberry, bubble gum, lemon-lime, and all the usual candy flavors.

Gummies are great if you like candy and do not want to mess around with making a drink, just grab a few gummies and get going!

Pre Mixed

Surprisingly, the premixed supplements seem to be the least popular form. You would think that because they are so easy to use, they would be dominating, but that is not the case. There are only a handful of good pre-workouts that are made in the premade liquid form. They look like the popular vitamin water you may have seen before.

The pricing for the premixed is like the other 2 forms with no significant difference for the liquid form.

Of course, you may be familiar with Monster energy drinks and the avalanche of energy drinks out there. These are not the same as pre-workout supplements, but some people like to drink them before a workout just for the pure energy buzz. These ‘energy drinks’ could technically qualify as premade, but they are not quite official pre-workout supplements.

Whichever form of these you choose to use, they will all have similar ingredients and produce similar results. The different forms are just here to make it more convenient for you to consume them in the way that is easiest for you in your life. Personally, I think the powders are the winners for the simple fact that you get more bang for the buck and one scoop is all you need with most of them for a full day’s energy where it would take several gummies.

Features to Look For

There are a few key things to consider when you are choosing the best pre-workout supplement for your personal use. Obviously, the different forms of these supplements should be considered, choose the one which matches up with your lifestyle and personal preferences.

Beyond your personal preference in the form of the supplement, there are 3 things that I think are the most important factors to consider before making the purchase:

  • Safe and Natural Ingredients
  • Fits with Your Fitness Goals and Body Type
  • Does Not Contain Unhealthy Substances

Safe and Natural Ingredients

best pre-workout supplementsThere are so many supplements out there with hundreds of fancy-sounding ingredients that use long and scientific works to describe them. It is difficult to know what the heck you are putting in your body while reading the ingredient list!

This is not by any means a full accounting of all the natural ingredients you will find in these supplements, but it is a list of some of the most common.

L-Theanine

This sounds like a lab-created chemical, but it is actually a naturally occurring compound that is found in black or green tea and even in certain mushrooms. It is natural and does have some health benefits.

Beta-alanine

This is something that occurs naturally in the body, so it is quite natural. However, its use in pre-workout supplements is inconclusive by fact-based science. There have been some small tests showing it helped endurance, but nothing on a large scale with multiple third-party testing.

Maltodextrin

This is a white powder that is technically natural because it comes from wheat, rice, corn, or potato, which are all naturally occurring. However, maltodextrin is weird because it is heavily processed to get the form it comes in, a powdery white substance. It is typically used as a filler to make these supplements more substantial. It is a high-carb substance. It is safe but it is just very starchy and contains lots of carbs.

L-citrulline

It is an amino acid, but it is unique in the way that it is not used to create protein. L-citrulline is found in watermelon which is, of course, a natural source. It has many uses in the medical world and is beneficial for many things, including:

  • High blood pressure
  • Erectile dysfunction
  • Heart failure
  • Sickle cell disease

It is also made naturally in the body. The body will transform it into a different amino called L-arginine, as well as nitric oxide. The fact that it helps produce nitric oxide is why it is present in these supplements.

Fits with Your Fitness Goals and Body Type

When choosing the right one be sure to pay special attention to what it is designed to do and who it is designed for. If you are someone who does not tolerate caffeine very well, you want to make sure you get one that does not have a lot of caffeine.

Almost all of them do contain caffeine, but there can be a dramatic difference in how much caffeine each one has. Some have as little as 100 Mg, while others have over 300 Mg (that is a LOT).

If you are just starting and doing light workouts with some free weights in your home gym or some bodyweight exercises and jogging, you do not need a hardcore supplement that gives you insane amounts of energy that you will not burn off. You will end up wide awake in bed when you should be sleeping, and nobody wants that! You need to match up your activity level with the amount of caffeine and energy each one produces.

If you are a serious weightlifter, you know you will need a serious energy supplement with lots of muscle repair and building capabilities. This is a completely different kind of supplement from the type of supplements newbies will need. For serious athletes, the caffeine will be burned off faster and will be better tolerated.

There are some of these supplements that make it easy to know if it is right for you. For example, some are specifically made to help with weight loss, some are made just for runners, some are for early morning workouts.

Does not Contain Unhealthy Substances

Sugar

These are almost all sweet-tasting flavors, and to get sweet, you need something like sugar or sugar alcohols. While sugar products are not going to kill you, they are not good for you. There is no need to get excess sugar in your diet, so keep an eye out for sugar alcohols in these supplements.

Caffeine

Caffeine is present in almost all of them! This is something everyone is familiar with and it is found in coffee, tea, soda, and many other sources. Caffeine is not a harmful chemical by itself, but in excess, it can be dangerous causing anxiety, heart issues, and restlessness. Make sure you look at the labels and find out exactly how much caffeine is in your supplement. It is quite easy to overdo it when the thing tastes so good. Be careful with caffeine intake, it can sneak up on you and ruin your day.

Creatine

While creatine is naturally produced by the body, it is also present in many supplements. Creatine is not dangerous on its own, but it is on this list because it does have some effects many people do not want. It is known to help build muscle, so it is extremely popular with weightlifters. However, there is a downside with creatine, it is known to make you gain weight and can cause some water retention. You will come across some of these that point out that they contain no creatine, which many people are looking for since creatine is known to help you gain weight which many people do not want!

The best pre-workout supplements are the ones that match your needs and budget. Hopefully, you were able to find one that works best for you!
