If you want to know more about essential amino acid supplements, you're not alone. Not only are they flooding the marketplace, but many people are also replacing their BCAA supplements with them. Essential amino acids (EAAs) play a vital role to help build and grow muscle, and by taking an EAA supplement, you're ensuring a bountiful supply of muscle food. Stay tuned because we've made finding the best essential amino acid supplement a bit less complicated. But first, what are essential amino acids?

There are 20 amino acids that make up protein molecules. Of those 20, nine of them are considered essential amino acids (EAAs) because the human body cannot produce them on its own. That means we need to consume them through our diet. If you're curious about where branched-chain amino acids (BCAAs) enter the equation, they are leucine, isoleucine, and valine, and make up 3 of the 9 essential amino acids. So essential amino acid supplements include BCAAs because BCAAs are also essential amino acids.

How to Choose the Best Essential Amino Acid Supplement

If you're interested in stepping out to do your own research, below are some things that you'll want to think about when looking for the best essential amino acid supplement.

BCAAs vs. EAAs

We touched on this earlier, but let's go a bit deeper. In the science community, we want to know what works best to support and increase muscle protein synthesis, or muscle growth. More recent evidence suggests that BCAAs alone might actually decrease muscle protein synthesis, thus working against muscle growth. And a plentiful supply of EAAs (which include BCAAs) can work to turn this around and increase muscle growth. Therefore, the consensus seems to be headed in the direction of essential amino acid supplements for the win.

Ingredients

The ingredient list is crucial in any nutritional supplement. In the case of essential amino acids, we obviously want to be sure that all nine essential amino acids are included on the nutrition facts list. Many supplement companies like to add additional beneficial ingredients that help with endurance or muscle recovery. An example of this is Tart cherry extract, a popular added ingredient to help with muscle recovery. It's important to always understand what's in your supplement prior to consuming it in order to avoid reactions and overconsumption of certain nutrients.

In addition to knowing and understanding the nutrients included on the nutrition facts label, it's important to know the source of the ingredients whenever possible. For example, many essential amino acids come from the byproducts of animals processed through the food industry. Feathers might be the source of amino acids in your product. Other companies use vegan amino acids from fermented vegetation. These things may or may not be important to you, but at least you can make an informed decision.

Certifications

It's always good to remember that the Food and Drug Administration (FDA) does not approve vitamin and mineral supplements prior to them being sold to the public. Therefore it's critical that the consumer do their own research when purchasing nutritional supplements. Of course, it's not possible for us to peer through the window of manufacturing facilities to do our own investigation, therefore we rely on third-party certifications to hold companies accountable.

These companies test the supplements in batches at their own facilities. It varies but they mostly look for safety, composition, purity, banned substances, and heavy metals. Once the product passes the test, they give their seal of approval in the form of certification. The consumer can feel more confident buying the product. Some third-party certifications to look out for include NSF International certification, QAI International certification, GMP (Good Manufacturing Practices) certification, and Informed-Sport Certification.

How We Rate Supplements


Price/Affordability (scale of $-$$$)

Prices depend on a number of factors, and tend to fluctuate over time, so we've kept our affordability rating scale simple so you can easily see how products compare:

$ = under $1 per serving
$$ = $1-2 per serving
$$$ = over $2 per serving

Flavor Options (scale of 1-3)

When it comes to dietary supplements that you take frequently, or even daily, options are important. And while your protein powder or pre-workout doesn't have to taste good to be effective, having several flavors to choose from can make it easier to stick with your fitness and health goals.

N/A = Unflavored
1 = 1-2 flavor options
2 = 3-4 flavor options
3 = 5 or more flavor options

FAQs About Essential Amino Acid Supplements


Should I be taking BCAAs or EAAs?

Based on the latest review by the International Society of Sports Nutrition, an ample amount of all EAAs can increase muscle growth. Whereas BCAAs alone might actually slow or decrease muscle growth based on total protein consumed throughout the day. Bottom line, EAAs will not only give you more bang for your buck, but they'll get the job done.

How many EAAs should I take daily?

There is currently no consensus yet on the daily recommended amount of essential amino acids. As you've seen from our picks above, EAA supplements usually range from 3-10 grams per serving. It's always important to ensure you're meeting your protein needs first and taking an EAA supplement based on what works for you. When in doubt, you might want to choose a midrange product with about 6 grams per serving.

Do EAAs really work?

In short, yes, they do. It's important to remember that EAAs are simply amino acids, which are the building blocks of protein. As you likely know, a sufficient amount of protein will help build muscle, so in that sense, if your protein needs are met, EAAs definitely work. Research indicates that when all EAAs are present, muscle protein synthesis is stimulated. In other words, EAAs help improves muscle growth.

What are the benefits of EAAs?

Essential amino acids are broken-down elements of protein that help to grow muscles post-exercise. Taking an EAA supplement provides your body with easily absorbed muscle building blocks to improve muscle growth and repair.
