BCAAs or EAAs: A Beginners Guide to Which is Right for You

Much like with fashion, supplements tend to trend, too. Every fitness expert is raving about a supplement, and you start to wonder: should I be taking this supplement? In recent years, the hot supplement was BCAAs, but now you’re probably starting to hear more and more people talk about EAAs. What’s the deal?

EAAs and BCAAs are both amino acid supplements that people use to energize, hydrate, grow, and recover their muscles. There are differences in the products, and under certain conditions, one might be a better option than the other.

What are Amino Acids?

Amino acids are naturally occurring, organic compounds that come together in our bodies to form proteins. We often refer to amino acids as the building blocks of proteins, and proteins are the building blocks of life.

When we consume protein, our body digests and breaks down the food until amino acids are left. Our body then uses amino acids for energy, to digest food, grow, heal tissue, and more.

There are three kinds of amino acids:

  1. Essential amino acids

The body cannot make essential amino acids on its own. We must get them from our food. The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

  1. Nonessential amino acids

Our bodies can use other sources to produce nonessential amino acids, even if we don’t consume them. The nonessential amino acids are alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.

  1. Conditional amino acids

These amino acids are typically nonessential, except for in times of illness or increased stress. Conditional amino acids are arginine, cysteine, glutamine, tyrosine, glycine, ornithine, proline, and serine.

The term complete proteins refers to foods containing all nine essential amino acids. While consuming all amino acids through a day of eating is important, we no longer worry that each meal must contain all amino acids because supplements exist.

What do Amino Acid Supplements Do?

Amino acid supplements refer to dietary supplements that contain essential amino acids. Branched-chain amino acids are essential amino acids, but not all essential amino acids are branched-chain in their molecular structure.

Athletic people use amino acid supplements to boost their performance and maintain or grow their muscles.

Amino acid supplements may help to:

  • Temporarily raise pain tolerance during exercise
  • Reduce the perception of fatigue during exercise
  • Improve recovery time
  • Improve immunity
  • Improve aerobic or cardio performance
  • Improve circulation aiding in increased endurance
  • Increase strength and grow lean muscles
  • Increase antioxidant production
  • Provide relief from inflammation and oxidative stress
  • Prevent excess muscle catabolism
  • Change how your body metabolizes fats while exercising

Do Amino Acid Supplements Work?

You’re not alone if you wonder if supplements are as good as the “real thing.” Assuming you choose a quality supplement brand, many scientific studies show amino acid supplements are effective.

While the supplements are effective, it’s important to note that you get amino acids from your food, and if you’re getting enough, additional amino acids won’t make a difference. Foods that contain amino acids are foods that have protein.

Complete protein sources or foods that contain all nine essential amino acids are:

  • Fish
  • Poultry
  • Beef
  • Eggs
  • Dairy
  • Whole sources of tofu, and more 

Remember, though, that our bodies can combine amino acids to create complete proteins, so if you’re vegan or don’t eat meat and dairy, you could potentially still get enough amino acids. Most likely, if you hit your daily protein goals, you’re getting enough protein. However, if you fail to meet your protein goals every day, you might also fall short on amino acids and benefit from an amino acid supplement. So, which one is right for you?

What are EAAs?

EAAs stands for essential amino acids. EAA supplements contain all nine essential amino acids, including the three branched-chain amino acids. You can use EAAs at any time during the day; however, evidence suggests that taking your EAAs before or during your workout is ideal.

EAAs are beneficial because we know that all essential amino acids are required to create and maintain muscle mass. EAAs offer assurance that your diet always contains the essential amino acids and can always create new muscle after you exercise and lift weights. 

What are BCAAs?

BCAAs refers to branched-chain amino acids. Branched-chain amino acids are three essential amino acids with a branched molecular structure.

The BCAAs are: 

  • Leucine
  • Isoleucine
  • Valine

These three essential amino acids play a crucial role in muscle preservation and growth, which is why BCAAs were the first amino acids supplement to get a lot of attention. BCAAs are also unique in that they are the only essential amino acids that can bypass the liver and move directly to the muscles via the bloodstream, where they serve as a source of energy.

BCAA supplements ensure you have adequate amounts of the amino acids required to synthesize new muscle growth; however, they can’t do the work independently. BCAAs still need the other amino acids to begin their work.

What is the Difference Between BCAAs and EAAs?

BCAAs are three of nine amino acids. EAAs contain BCAAs and all the other essential amino acids. BCAAs need the other amino acids to do their job, but they can pull from other food sources to get them. Check out this visual representation of the differences.

Better taste




Note that BCAAs tend to taste better than EAAs. Due to the nature of combining various amino acids, companies tend to have an easier time flavouring BCAA products.

When Should I Use EAAs?

Choose an EAA supplement if you struggle to meet protein requirements. If you don’t eat enough protein to support your goals, you’re likely falling short on amino acids as well. Adding all nine EAAs to your diet ensures your muscles are getting what they need so you can reach your goals.

You can take EAA supplements before, during, or after a workout and on rest days. Experiment and find what works best for your body.

When Should I Use BCAAs?

If you consistently meet your protein goals, go with BCAAs. If you’re getting the other essential amino acids from your diet, including your other protein supplements, BCAAs are the only amino acids you need to supplement your food.

Additionally, if you have tried EAA supplements and don’t enjoy the taste and flavours, taking a BCAA supplement is better than nothing if you know you would benefit from a daily dose of amino acids.

Should I Take Both BCAAs and EAAs?

Because EAAs contain BCAAs, it would be unnecessary to consume both. If your goal is to ingest all nine essential amino acids from a protein supplement, choose EAAs.

The bottom line is that both EAAs and BCAAs are great protein supplements. Each supplement supports muscle maintenance, growth, and recovery. In general, EAAs are best for people who fail to eat enough protein regularly, and BCAAs are ideal for those who eat enough protein but would like assurance that they’re consuming enough of the branched-chain amino acids required for building muscles.

You can get all EAAs from your diet and protein supplements. If you choose to get your EAAs and BCAAs from protein supplements, just ensure they have adequate BCAA ratios and are complete protein sources.
