EAA vs. BCAA: Which amino acids are better for your muscle building

If you have ever looked into nutritional supplements in sports, you have probably come across the terms BCAA and EAA . Both are often advertised as support for muscle building and regeneration, but what exactly are BCAAs and EAAs? How do they differ, and which of the two supplements is more useful for your training? In this article, you will learn the differences between EAA (essential amino acids) and BCAA (branched chain amino acids), their advantages and when using them might make sense for you.

What are amino acids?

Before we dive into the differences between EAA and BCAA, it's important to understand what amino acids actually are. Amino acids are the building blocks of proteins, which in turn are necessary for building and repairing muscle tissue. There are a total of 20 different amino acids, 9 of which are considered essential because the body cannot produce them on its own and they must be obtained through food.

The most important essential amino acids (EAA) are:

• Leucin

• isoleucine

• valine

• lysine

• methionine

• phenylalanine

• threonine

• tryptophan

• histidine

What are BCAAs?

BCAAs (Branched-Chain Amino Acids) are branched-chain amino acids and include three of the nine essential amino acids: leucine , isoleucine and valine . They get their name from their chemical structure, which has branched side chains. These three amino acids play a crucial role in muscle building and energy production during exercise.

Benefits of BCAAs

1st Muscle building and maintenance : Leucine in particular is a key amino acid that stimulates muscle protein synthesis and thus supports muscle building. BCAAs can also help prevent muscle breakdown during intense training sessions.

2nd Energy source during training : BCAAs can be used by the body as an additional energy source during training, especially during long endurance sessions or intense workouts.

3. Reducing muscle soreness : Some studies suggest that BCAAs may reduce muscle damage after exercise and thus reduce muscle soreness.

When BCAAs are useful:

• For intensive strength or endurance training , when you want to support your muscles during training.

• During longer training sessions to prevent muscle loss and promote energy production.

• If you are on a diet-induced calorie restriction and want to ensure that your muscle mass is maintained.

What are EAAs?

EAAs (Essential Amino Acids) are all nine essential amino acids, including the three BCAAs (leucine, isoleucine and valine). However, unlike BCAAs, EAAs also contain amino acids such as lysine , threonine and phenylalanine , which are also important for muscle building and other bodily functions.

Benefits of EAAs

1st Complete Amino Acid Profile : EAAs contain all the essential amino acids the body needs. This makes them a “complete” amino acid supplement that supports not only muscle building but also other important functions in the body.

2nd Muscle Protein Synthesis : Studies show that a complete supply of all essential amino acids (EAAs) stimulates muscle protein synthesis better than BCAAs alone. This means that EAAs may be more effective at supporting muscle growth.

3. Promotes recovery : By consuming EAAs, the body can regenerate faster because it has all the building blocks it needs to repair muscle damage.

4th Support for general health : In addition to building muscle, the EAAs not found in BCAAs support important functions such as the immune system, hormone production and tissue regeneration.

When EAAs make sense:

• For people who strive for maximum muscle growth , as EAAs provide all the building blocks the body needs.

• If you are looking for a more balanced supplement that not only targets energy production and muscle protein synthesis, but also supports other essential body functions.

• During intensive training sessions or during a diet phase when a more comprehensive supply of amino acids is required.

BCAA vs. EAA: Which is better?

The question of whether BCAAs or EAAs are better depends on your individual goals. BCAAs have their advantages, especially when it comes to supporting energy production during exercise and preventing muscle breakdown. Leucine , one of the BCAAs, is particularly effective in stimulating muscle protein synthesis.

EAAs, on the other hand, offer a more comprehensive solution as they contain all nine essential amino acids that are important for muscle building and overall health. Studies show that EAAs have a greater effect on muscle protein synthesis than BCAAs alone because the body needs more than just the three BCAAs for complete muscle building.

When are BCAAs useful?

• For short, intensive training sessions or if you want to specifically use leucine for muscle protein synthesis.

• If you already have a high protein diet and need additional energy for your muscles during training.

When are EAAs useful?

• For comprehensive support in muscle building as they contain all essential amino acids.

• If you want to ensure that your body receives all the necessary building blocks for muscle regeneration after training.

Conclusion

Both BCAAs and EAAs have their place in the world of sports supplements. While BCAAs can be particularly useful for energy production and quick delivery to muscles, EAAs provide a more comprehensive amino acid supply that better supports muscle building and overall health.

If you're just looking for a small addition to your workout or are on a high-protein diet, BCAAs may be sufficient. However, if your goal is maximum muscle growth, comprehensive recovery, and a full supply of essential amino acids, EAAs may be a better choice.

In the end, the decision depends on your personal training goals, your diet and your preferences. Both supplements can be a useful addition to your training routine - provided they are used specifically and in the right context.
