BCAAs vs. EAAs: Which Amino Acids Should You Choose?

  • 4 min read

When it comes to optimising your fitness and health, understanding the differences between Branched-Chain Amino Acids (BCAAs) and Essential Amino Acids (EAAs) is crucial. Both play vital roles in muscle recovery, energy production, and overall health. This article will delve into the specifics of BCAAs and EAAs, helping you decide which amino acid supplements might be best for you.

What Are Amino Acids?

Amino acids are the building blocks of proteins, which are essential for nearly every bodily function, including muscle repair, enzyme production, and hormone synthesis. There are 20 amino acids, nine of which are considered essential because the body cannot produce them; they must be obtained through diet or supplements.

Understanding BCAAs

What Are BCAAs?

BCAAs, or Branched-Chain Amino Acids, consist of three essential amino acids: leucine, isoleucine, and valine. They are termed "branched-chain" due to their unique chemical structure. BCAAs are particularly well-known for their role in muscle metabolism and energy production during exercise.

Benefits of BCAA Supplements

  1. Muscle Protein Synthesis: Leucine, one of the BCAAs, is especially potent in stimulating muscle protein synthesis, which is crucial for muscle growth and repair.
  2. Reduced Muscle Soreness: BCAA supplements can help decrease muscle soreness after intense exercise, aiding faster recovery.
  3. Enhanced Exercise Performance: By reducing fatigue during workouts, BCAAs can help improve exercise performance and endurance.

How to Take BCAA Supplements

BCAA supplements are typically taken before, during, or after workouts to maximise their benefits. They are available in various forms, including powders, capsules, and carbonated drinks.

Exploring EAAs

What Are EAAs?

Essential Amino Acids (EAAs) include all nine amino acids that the body cannot produce on its own: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. EAAs must be obtained through diet or supplements.

Benefits of Essential Amino Acids

  1. Comprehensive Protein Synthesis: EAAs provide a complete profile necessary for full protein synthesis, supporting overall muscle growth and repair.
  2. Better Muscle Preservation: EAAs help in preserving muscle mass, especially during periods of caloric deficit or intense training.
  3. Improved Nutrient Absorption: EAAs play a role in improving the absorption of nutrients, contributing to overall health and wellness.

How to Take EAA Supplements

EAA supplements can be taken at any time of the day, though many athletes prefer to consume them around their workouts to enhance muscle recovery and growth.

Which Is Better, EAAs or BCAAs?

The debate over whether EAAs or BCAAs are better largely depends on individual goals and dietary habits.

Advantages of BCAAs

  • Targeted Muscle Support: BCAAs are particularly effective at stimulating muscle protein synthesis due to the presence of leucine.
  • Immediate Energy Source: During intense workouts, BCAAs can be used directly by the muscles for energy.

Advantages of EAAs

  • Complete Amino Profile: EAAs provide all nine essential amino acids, ensuring comprehensive support for muscle growth and repair.
  • Versatility: EAAs support not only muscle protein synthesis but also overall bodily functions, including immune response and nutrient absorption.


If your primary goal is to enhance muscle growth and recovery, especially around your workouts, BCAAs might be more beneficial. However, if you're looking for a supplement that provides overall amino acid support for various bodily functions, EAAs are the superior choice.

Should You Take BCAA and EAA Together?

Combining BCAA and EAA supplements can provide a synergistic effect, offering both the targeted benefits of BCAAs and the comprehensive support of EAAs.

Benefits of Combining BCAAs and EAAs

  1. Enhanced Muscle Protein Synthesis: The presence of leucine in BCAAs boosts muscle protein synthesis, while EAAs provide the full spectrum of amino acids necessary for complete protein formation.
  2. Improved Recovery and Performance: This combination can help in faster recovery, reduced muscle soreness, and improved exercise performance.
  3. Balanced Amino Acid Intake: Ensuring a balanced intake of all essential amino acids can support overall health and wellness.

How to Combine BCAA and EAA Supplements

To combine BCAAs and EAAs effectively, you can take BCAAs around your workouts for immediate muscle support and EAAs at other times of the day to ensure a balanced intake of all essential amino acids.

The Role of Amino Acids in Diet

While supplements can provide convenient support, obtaining amino acids from a well-rounded diet is also important. Foods rich in essential amino acids include:

  • Meat and Poultry: Chicken, beef, and turkey
  • Fish and Seafood: Salmon, tuna, and shrimp
  • Dairy Products: Milk, cheese, and yoghurt
  • Plant-Based Sources: Quinoa, soy, and legumes

Incorporating these foods into your diet can help ensure you get a sufficient amount of all essential amino acids.

Choosing the Right Supplement

When selecting amino acid supplements, consider the following factors:

  1. Quality: Choose high-quality supplements from reputable brands to ensure purity and efficacy.
  2. Form: Decide whether you prefer powders, capsules, or ready-to-drink options based on your convenience.
  3. Goals: Align your supplement choice with your specific fitness and health goals.

Common Questions About Amino Acid Supplements

Are Amino Acid Supplements Safe?

Amino acid supplements are generally safe when taken as directed. However, it's important to consult with a healthcare professional before starting any new supplement regimen, especially if you have underlying health conditions.

How Much Amino Acid Supplement Should I Take?

The recommended dosage can vary depending on the specific supplement and your individual needs. Typically, BCAA supplements are taken in doses of 5-10 grams before or after workouts, while EAA supplements are taken in doses of 10-20 grams daily.

Can You Get Enough Amino Acids from Diet Alone?

While it's possible to get sufficient amino acids from a well-balanced diet, supplements can provide additional support, especially for athletes and those with higher protein needs.


Understanding the differences between BCAAs and EAAs can help you make informed decisions about your supplement choices. Both types of amino acids offer unique benefits, and your choice should align with your specific goals and dietary habits. Whether you opt for the targeted support of BCAAs or the comprehensive benefits of EAAs, incorporating amino acids into your fitness routine can enhance muscle growth, recovery, and overall health.
