Buyers’ Guide

When you are buying an EAA supplement, you should be looking for one with a flavor you enjoy as well as several benefits that should enhance your aerobic performance.

The 10 Best EAA Supplements To Buy

These essential amino acids are ones that your body fails to synthesize as they are produced through ingestion.

The nine to look out for are leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, tryptophan, and threonine. 

Their benefits include improving your muscle strength and supporting muscle growth. They should also support your metabolic health, prevent any muscle loss, reduce any muscle soreness and the occurrence of DOMS. Finally, EAA supplements should support your immune system.


The BCAA ratio in an EAA supplement is something to look out for as there are certain ingredients that you should hope to find. You may favor these ingredients over others so the ratios do come into play. 

For instance, you could have a 3:1:1 ratio of three grams of leucine for every gram of valine and isoleucine. That can be compared to other supplements so you can pick and choose. 

Amino Acid Profile

The amino acid profile is important yet there is typically less difference across most supplements. The three dominant amino acids should be leucine, isoleucine, and valine. 

Further down the profile, you should find lysine, threonine, and phenylalanine in diminishing amounts. Finally, tryptophan, histidine, and methionine should be included but to a lesser extent. 


The number of servings in each container is a good indication of how much value for money you can achieve.

Instead of comparing the weight of each container across the range of supplements, you should divide the cost by the number of servings to find out the individual cost of each serving. 

It may be preferable to find a container with as many as 30 servings that can last you over a month.

That should be a general average yet you can find some containers that hold as many as 100 servings yet may cost more per serving. There is also the amount of space you will have free to hold the container.


If the EAA supplement tastes good, there is more chance you will enjoy consuming it. There will be some manufacturers who decide that unflavored is the way to go.

However, many have provided a range of fruity flavors, some supplements can come with up to nine, even eleven flavors. 

While that may be too much choice, you should be able to find one you like though lookout for one that boasts that it does not contain any artificial flavorings.

Electrolytes/Hydration Mix

The electrolytes are essential for ensuring that the EAA supplement can keep you hydrated. They tend to include taurine, Albion minerals, and coconut water powder.

Not only can these ingredients aid your hydration but they will also go some way to helping your muscle recovery and muscle performance.

This is essential if you perform a gym workout in a hot environment as you can quickly find yourself dehydrated unless you keep on top of your fluid intake.


The amount of caffeine in each serving can sway you between supplements. Some supplements boast that their formula is caffeine-free which may be ideal if you prefer to workout at night and do not want to be kept awake. 

However, you may prefer the caffeine for that initial boost alongside your daily caffeine intake from coffee and tea.

Try to search out organic caffeine simply so it provides you with a more natural reaction as opposed to anything synthetic.

If you do opt for an EAA supplement with caffeine then you may discover that you can take it in the morning simply for that boost. Aside from that, it can simply be taken as a pre-workout so you enjoy the benefit during your gym session. 

A good amount of caffeine to look out for maybe as much as 100mg. However, try the EAA supplement at various times of the day as it could mean that you only enjoy a small-term energy boost and not the long-lasting effect you desire.

Ingredient Profile

Sometimes it is not just the ingredient profile itself that matters but how transparent the manufacturers are in displaying it.

Each ingredient should be listed alongside its specific quantity and even ratios. Alongside the nine amino acids, you can also expect caffeine to be included too in the form of green tea and green coffee bean extract. 

If the ingredient profile includes proprietary blends then the exact quantities of certain ingredients may be unknown which can be a concern.

The use of filler ingredients can also be an issue as you do not want your supplement to have any artificial ingredients and flavorings. The list of ingredients should be extensive, transparent, high-quality, clean, and active.
