Our “WOW Factor” Buyer’s Guide

You're probably wondering what are EAAs and why you should be taking them.

Most people have never even heard of EAAs, let alone know why they would want to take them.

EAA supplements are essential amino acids that your body needs in order to perform optimally. They are the building blocks of protein and help your muscles recover after a workout.

Here are the most frequently asked questions about EAA Supplements and our answers to them.

What should I look for in an EAA supplement?

There are many things to look for when choosing an EAA supplement.

The most important thing is to make sure that the supplement you choose provides all of the essential amino acids in adequate amounts. Not all EAAs are created equal, and some supplements may be lacking in one or more of the essential amino acids.

In addition to looking for a complete EAA supplement, it is also important to choose a supplement that contains EAAs in a ratio similar to that found in nature. Our bodies are designed to utilize proteins from food sources, which means that we are able to absorb and use EAAs from dietary sources more efficiently than from supplements.

Therefore, it is best to find a supplement with a natural ratio of EAAs.

What is the difference between EAA and BCAA?

Essential Amino Acids (EAAs) are those that the human body cannot produce on its own and must be consumed through diet.

Branched Chain Amino Acids (BCAAs) are a subset of EAAs that have a unique structure and perform specific functions in the body.

The main difference between EAAs and BCAAs is that EAAs are needed for basic bodily functions while BCAAs support exercise performance and recovery.

EAAs are used by the body for a variety of purposes such as rebuilding tissue and producing hormones, and enzymes, while BCAAs are primarily metabolized in muscle tissue and used during exercise to prevent protein breakdown.

While all BCAAs are EAAs, not all EAAs are BCAAs.

What are the best sources of EAAs?

There are two main sources of EAAs: food and supplements.

The best dietary sources of EAAs are animal-based proteins such as meat, poultry, fish, and eggs. However, it can be difficult to get enough EAAs from diet alone, especially if you are vegetarian or vegan.

This is where supplements come in. EAA supplements can provide the body with a complete and balanced blend of all the essential amino acids, making it easier to get the nutrients you need.

Is EAA better than creatine?

There is no definitive answer to this question as research on the topic is ongoing. Some studies have shown that taking EAA supplements may be more beneficial than taking creatine supplements, while other studies have found no difference between the two.

Ultimately, more research is needed to determine which supplement is better for increasing muscle mass and strength.

When should I drink EAA?

For best results, drink EAA before and after your workout. EAAs help to promote muscle growth and reduce muscle fatigue.

Does EAA cause hair loss?

No, EAA does not cause hair loss.

There are a number of factors that can contribute to hair loss, including genetics, age, hormones (e.g., testosterone), and lifestyle choices (e.g., smoking, drinking). While there is some evidence that suggests certain amino acids may play a role in hair loss, there is currently no scientific evidence to support the claim that EAAs cause hair loss.

Can you take too much EAA?

There is no such thing as "too much" EAA. Your body will only absorb and use what it needs, and the rest will be excreted. So if you're taking more than your body needs, you're just spending your money.

Can I take both EAA and BCAA?

Yes. Studies have shown that athletes who supplemented with both BCAA and EAA had increased muscle protein synthesis (MPS) compared to those who only supplemented with BCAA or EAA alone.

Branched-chain amino acids (BCAAs), which include leucine, isoleucine, and valine, are essential amino acids that play an important role in muscle protein synthesis. In addition, essential amino acids (EAAs) are the building blocks of proteins and are required for tissue growth and repair.

That said, it's important to note that not all EAAs are created equal. Some EAAs may be more effective than others at promoting MPS. For this reason, it might be a good idea to supplement with a complete EAA formula that contains all of the EAAs in the proper ratios.

The best way to get all the EAAs your body needs is through diet and supplementation. Food sources of EAAs include animal-based proteins such as meat, poultry, fish, and eggs. However, it can be difficult to get enough EAAs from diet alone, especially if you are vegetarian or vegan. This is where supplements come in. EAA supplements can provide the body with a complete and balanced blend of all the essential amino acids, making it easier to get the nutrients you need.

What amino acids should not be taken together?

There are a number of different amino acids that should not be taken together because they can compete for absorption.

For example, eating large amounts of histidine and methionine can interfere with the absorption of tryptophan. Similarly, consuming too much leucine can hinder the uptake of isoleucine and valine.

Of course, it's also important to make sure that you're getting a balanced diet that includes all the essential amino acids. So if you're not sure which amino acids to take together, it might be best to consult with a nutritionist or dietitian.

What are the side effects of EAA supplements?

Although there are no known major side effects of taking EAA supplements, it is always important to consult with your physician before starting any new supplement regimen, particularly if you have a medical condition or are taking any other medications.

Some of the potential minor side effects that have been reported with taking EAA supplements include nausea, headache, fatigue, and irritability.

If you experience any of these side effects while taking EAAs, it is recommended that you discontinue use and consult with your physician.

Can you take EAA without working out?

There are a lot of factors to consider when it comes to taking EAA without working out, and ultimately the decision comes down to your individual goals.

If you're looking to improve your overall health and performance, then working out is really the best way to go.

However, if you're just trying to build muscle mass or recover from an injury, then EAA can be helpful even without exercise. It all depends on what you're hoping to achieve.

Our Best Advice

Looking for the best EAA supplement? We’ve spent dozens of hours reading thousands of reviews on Amazon from verified customers to find the perfect EAA supplement for your needs.   Here are a few things to keep in mind.

The first thing to remember is that EAAs (Essential amino acids) are not exactly the same thing as BCAAs (Branched Chain amino acids).  BCAAs are more well-known in the workout space but they are a subset of the more general EAAs.  The thing is that your body needs all nine essential amino acids for muscle protein synthesis and for other health benefits.

In fact, there are a number of critical amino acids that fall outside of the typical BCAA group but that is part of the nine essential amino acids.  Therefore a good essential amino acid supplement is, well, essential for muscle growth, recovery, and protein synthesis.  Essential amino acid supplements, therefore, need to be part of your daily routine.

Secondly, there is an issue of ratios between EAAs and BCAAs which also needs to be respected.  Getting the ratio right between nonessential amino acids and essential amino acids required for lean muscle growth is one thing but even between different essential amino acids, it is important.  A good protein powder will promote optimal protein synthesis by providing both BCAA supplements and EAA supplementation in their proper ratio.

Protein supplements in general do a good job of putting together free-form amino acids with specially selected amino acids to increase muscle protein synthesis.  They may even create an electrolyte blend, or add citrulline malate or green coffee bean extract (or green tea extract) for a more natural source of caffeine.

Choosing the best essential amino acid formula (perhaps with citrulline malate) together with BCAAs in an optimal EAA ratio creates a great pre-workout protein powder as well.  Sometimes whey protein is used in pre-workout supplements to prevent muscle breakdown and increase blood flow (with the addition of L-Arginine and L-Glutamine) and promote the ability to lose weight and support protein synthesis in the body.

Supplement intake and protein intake (whether whey protein or something else) are important when building muscle mass since it is unlikely that you will get sufficient amounts of the nine amino acids without it.  Protein powders and BCAA supplements go hand in hand.  Now it is time to add a good amino acid supplement with all of the nine essential amino acids for clear muscle gains and maximize muscle protein synthesis.

So whether we are talking about an essential amino acid or nonessential amino acids, about protein powders or coconut water powder, muscle repair and amino synergy are the key issues.  Some will include citrulline malate and L-glutamine, while others will include green tea extract.  Most EAA supplements will include at least the basic three amino acids for amino synergy and enhanced muscle recovery.

Some people want to lose weight, while others want weight gain.  Some are focused on lean muscle repair and others on muscle anabolism.  Some are focused on pre-workouts, others on an intra-workout strategy, and still others on post-workout recovery.  Some want a daily dietary supplement to build muscle and others are concerned about artificial sweeteners and the pros and cons of whey protein.

Whatever it is that you are looking for in an essential amino acid supplement, whether results or recovery (or both), the key is to understand what it is that you are looking for in amino acid supplements (and protein supplements) on the one hand, and then understand the ingredients (from coconut water powder to artificial sweeteners to amino synergy) and what they can do for you on the other.

Some people have a favorite brand (such as Huge Supplements or Kaged Muscle Amino Synergy) while others have a favorite blend (such as EAA Surge).  But, regardless of which amino acid supplements you use, or whether you use them as pre-workouts or post-workouts, the issue is to use them.

Both EAA Surge and Kaged Muscle Amino Synergy are good essential amino acid supplements.  They will both provide a good essential amino acid blend and are considered strong candidates for the best in EAA Supplementation.

There are other amino acids than EAA Surge (with or without coconut water powder) that function just as well as pre-workout supplements, so there is a lot to choose from.  We, also, have our favorites.

So, without further delay, it is now time to reveal our top choice for the best of the best in EAA supplementation.  Drum roll, please...
