Difference Between BCAA and EAA

Difference Between BCAA and EAA

There are 20 different types of amino acids that can be used to build proteins. These molecules come from foods such as meats, vegetables, or grains but even your own body has some! The body can’t make important amino acids by itself, so people need to consume supplements. The nine essential or important amino acids are known as the EAAS. BCAAs make up three of these, making them an important contribution to our body’s needs for this element.


Branched Chain Amino Acids (BCAAs) are essential to our well-being because they make up 3 out 9 amino acids which we need for life. The human body cannot produce the nine essential amino acids (EAAs) on its own, so people must consume protein-rich food or supplement with these ingredients in order for their bodies to function properly.

The branched molecule structure of BCAAs makes them a highly effective source of protein. The 3 kinds of BCAAs are Valine, Isoleucine, and Leucine. They can be found in many supplements for sports enthusiasts to help them recover from their workouts quickly with increased energy levels that last all day long!

The human body is made up of many different parts, and each one has its own job to do. Amino acids are no exception! The 9 essential amino acids make sure that all these systems work together in perfect harmony for our health as well- being able not just survive but thrive too with this amazing protein we call “life.” There are nine different Amino acids, with lysine as its most common type and isoleucine at number 9 in terms of frequency among all other amino acid varieties!

Comparison Table Between BCAA and EAA

Parameters of Comparison The BCAA The EAA
Number of amino acids BCAAs are three essential amino acids. Valine, Leucine, and Isoleucine makeup BCAAS or Branched Chain Amino Acids 9 essential amino acids are present in EAAs.
Molecular structure The side chains of Branched Chain Amino Acids contain a central carbon atom bound to 3 or more amino acids. The molecular structure that makes up EAAs, or Essential Amino Acids as they’re also known can be found to form a major part alongside branched-chain of amino acids
Energy level The benefits of taking BCAAs before a workout are numerous, including increasing strength and endurance during training periods. While EAAs are not that effective in fighting muscle fatigue and for the increase of endurance, they do provide a boost during training periods.
Protein synthetic response The benefits of BCAAs are limited to those who exercise, but they have a low response of protein synthetic and should not be used outside the context of working out. The EAA’s in food are great for building muscle and increasing protein synthesis.
Immunity support The absence of histamine in BCAAs makes it difficult to support immunity as effectively. The EAAs found in raw ingredients like histidine can help with improving immunity and supporting a healthy body.

What is BCAA?

The three most essential amino acids are Leucine, Isoleucine, and Valine, or BCAAs for short. These particular molecules make up what’s known as the “branch-chain” which helps promote protein synthesis in our bodies leading to greater muscle mass over time! The benefits of branched-chain amino acids (BCAAs) for after-workout soreness of muscle and enhancing speedy recovery have been widely recognized by athletes.

We can obtain the following benefits from using the BCAA supplements:

  • The body gets a boost of energy and can push through those last few reps with ease. The use of BCAAs during your pre-workout helps give you that extra bit to make it into the gym, not just for today but every day!
  • The good sides of BCAA include enhanced recovery, reduced soreness in muscles.

Prime drawbacks of using BCAA supplements are:

  • BCAA can have a downside in that it may affect blood sugar levels and lead to an increase in insulin demand.
  • These are not suitable for lactating and pregnant women.
  • It can hamper your sleep cycle by lowering your level of serotonin.
  • It can also hamper other metabolisms of protein.

BCAAs are the ultimate way to get a quick pick-me-up, but a person may not be able to use them if they don’t have all nine essential amino acids.

What is EAA?

The EAAs are 9 essential amino acids that help our body function. It contains leucine, valine, lysine, isoleucine, methionines histidine, threonine, tryptophan, phenylalanine with an increase in strength endurance.

We can obtain the following benefits from using the EAA supplements:

  • When you take EAA, it has been shown to enhance protein synthesis of muscle because of its high concentration in essential amino acids.
  • The presence of a histidine-rich protein in this formula produces an increased level of activity for your immune system.
  • The benefits of taking this supplement are not just limited to weight loss. It also helps to provide a balance of hormones and can help keep your endocrine system functioning properly!

Major worries of using EAA supplements are:

  • The use of these supplements is not recommended for children. It may cause harm to their digestive system and bring about other negative effects too, so you should seek advice from a doctor before trying it in this case!

The EAA supplement is also known to be beneficial for weight management and detoxifying one’s blood. It might have mood-boosting properties that make people happy, too!

Difference Between EAA and BCAA

  • The branched-chain amino acids (BCAAs) have a single atom of carbon bound to the middle to 3 or more carbons, whereas essential Amino Acids (EAAs) constitute each of them.
  • BCAA is a group of three amino acids while EAAs contain all nine.
  • A great deal of research has proven that BCAA doesn’t have a convenient response when it comes to protein synthesis, while EAAs do respond very amazingly.
  • The lack of histidine in BCAA supplements means that they don’t provide as good an immunity boost if compared to the EAA.
  • BCAA is a great way to fight against muscle fatigue, while the EAAs we consume just don’t have enough effect.


The decision to choose between BCAA or EAA should be based on what the individual wants from their supplement. One must consider not only the price but also the use of each product before making an educated choice about which one is better suited towards meeting those needs/wants.

The use of EAA is important while on a vegan diet. One must seek advice from their trainer to ensure they select BCAA in sufficient amounts for proper intake and effectiveness if needed at all!
