As I have illustrated, BCAAs are essential for the bodybuilder and fitness enthusiast. However, trying to ensure that these important amino acids are delivered through food is extrem16ely difficult.

Firstly, it means a serious commitment to a diet heavin in BCAA foods.

Secondly, leucine, the most important of the BCAAs, is lacking in many foods, especially those that are plant based. This can make it difficult if you follow a vegetarian or vegan diet.

The best way to ensure you receive enough BCAAs for visible results is to supplement. Through intense research, I have found the best BCAA supplements available today.

What Are BCAAs and What Do They Do?

Firstly, I want to speak briefly about amino acids—it’s important to fully understand the BCAA definition.

The body is full of amino acids. These compounds are required to build proteins, gain muscle, power neurological activity and produce hormones. 1

Many of these amino acids can be synthesized by the body—it can produce them itself. However, there are some the body requires that cannot be synthesized.

These are termed “essential amino acids. The only way for them to enter the body is through ingestion, usually from food.

In total, there are nine of these important amino acids:

  1. Phenylalanine.
  2. Threonine.
  3. Tryptophan.
  4. Lysine.
  5. Methionine.
  6. Histidine.
  7. Leucine.
  8. Isoleucine.
  9. Valine.

Here’s the key.

It’s the final three that we are concerned about here. Leucine, valine and isoleucine—the essential amino acids that make up the branched-chain amino acids (BCAAs). This is what the best BCAA supplements contain. 2

These BCAAs constitute around 35 percent of all the amino acids found in muscle protein, making them of great importance to the bodybuilder. Without them, your resistance training is going to prove fruitless. 3

Each of these BCAAs has its own particular effect.

1. Valine

This BCAA has two important functions that are crucial if you’re looking to build muscle mass.

Firstly, studies have indicated it inhibits the power of another amino, tryptophan. This can stimulate feelings of hunger. By preventing its action, excess foods are not consumed, deterring unwanted fat. This leads to more defined muscles. 4 5

Secondly, during training, valine helps to supply muscles with additional glucose for energy. The excess ensures muscles are not used as energy stores, which helps to retain mass.

As an extra benefit, valine, together with the other two BCAAs, helps to boost the immune system. Therefore reducing the number of “off-days” from the gym. 6

2. Leucine

The most important BCAA for the serious bodybuilder.

As I’m sure you are aware, protein is essential for building muscle—just like a car requires gasoline to run. However, just filling your gas tank doesn’t make your car power down the road. You have to switch it on.

That’s exactly what leucine does.

It triggers the body into building muscle with proteins. The more of this amino acid you have, the faster and larger your muscles will build. If you were ever to take just one single BCAA, it should be leucine. 7

There’s more:

Leucine can boost levels of growth hormone, known to increase muscle mass. In addition, it can assist in weight loss by reducing cravings for starchy and sugary foods. 8 9 10

The best BCAA supplements will have leucine in a higher concentration than the other two BCAAs.

3. Isoleucine

This amino is perfect for bodybuilders who are looking to recover faster after intense and prolonged workout sessions.

Not only does it promote muscle repair post-workout, but it also increases endurance. Research has shown that isoleucine promotes the synthesis of hemoglobin, the carrier of oxygen in the blood. 11 12

The more oxygen transported to the muscles, the longer resistance training can be endured before fatigue sets in. 13

Many of these individual characteristics cross over between the three amino acids—to a greater or lesser extent. Combining them together provides the best results from one supplement.

What Are the Benefits of BCAA’s?

best bcaa supplements

It’s often a misnomer that BCAAs are for the sole use of the bodybuilder.

Let me tell you, this is incorrect.

BCAAs are, indeed, one of the most important supplements a bodybuilder can take.

However, they are also ideal for athletes, sportspersons and the general home-fitness enthusiast.

The benefits you receive from the best BCAA supplements depend on the work you put in. While they can help to build sizeable muscle mass, they still need to be combined with resistance exercise.

If you don’t lift weights, but instead compete in cycling, for example, they will help to retain lean muscle, assist with weight loss and improve aerobic capacity.

Remember this:

BCAAs respond to the work you put in, and give you the rewards you seek.

Here are the main BCAAs benefits.

  • Stimulates and boosts muscle protein synthesis. 14
  • Improves oxygen delivery to muscles.
  • Increases endurance and stamina.
  • Reduces recovery time, post exercise.
  • Assists in fat loss.
  • Helps to retain muscle.
  • Promotes energy from glucose as opposed to burning muscle.
  • Builds large muscle in combination with resistance exercise.
  • Boosts human growth hormone (HGH) levels.
  • Supports a healthy immune system.
  • Eliminates or reduces DOMS (delayed onset muscle soreness).
  • Prevents muscle wastage. 15

BCAA Dosage and Best Ratio

bcaa dosage

The ideal BCAA dosage depends on your requirements and what you are trying to achieve.

As a rule of thumb, the maximum dosage per day should be around 12 grams of BCAAs for women and 20 grams for men. Both of these limits are for people wanting to gain muscle mass through resistance training.

If however, you are looking to use BCAAs to help with weight loss or find the best BCAA for cutting—six grams per day is the ideal amount. That applies to both men and women.


BCAAs are one of the most natural, effective and scientifically proven ways to boost muscle growth, increase endurance, improve recovery and drop unwanted weight.

All the above supplements have their own particular benefits. But, which brand of BCAA is best?

The stand out product has to be transparent labs BCAA.


Do BCAAs Help You Lose Weight?

Yes. BCAAs can assist weight loss in two main ways.

Firstly, proteins stimulate the production of cholecystokinin—the hormone which “switches off” hunger.

Secondly, amino acids act to retain muscle mass while on a calorie controlled diet—you lose fat, not muscle. 30

What’s the Best Amino Acid in BCAA?

Theoretically, there is no “best” amino acid, as it depends on the results you are trying to achieve. However,if you are looking to gain muscle mass, leucine is the most important.

This is because this BCAA is responsible for “switching-on” the process of muscle protein synthesis which, in turn, promotes muscle growth.

What’s BCAA Good for?

BCAAs are essential for virtually every aspect of bodybuilding. They boost muscle growth, enhance performance, promote weight loss, improve recovery time and reduce fatigue.

Does BCAA Give You Energy?

Yes. The body uses energy from its stores of glycogen. Once depleted, you can utilize energy from BCAAs in the muscles. 31

Furthermore, BCAAs can block tryptophan, an amino acid which can create feelings of fatigue. 32

How Much BCAA Should a Man Take per Day?

If undergoing resistance training, 15 grams per day is ideal for gaining significant muscle mass. Six grams will suffice if looking to lose weight.

How Much BCAA Should a Woman Take per Day?

If looking to gain muscle,

10 grams per day taken alongside resistance training will yield impressive results. The best BCAA for weight loss dosage is around four to six grams per day.

When Should You Take BCAA’s?

BCAA levels are at their highest around 30 minutes after consumption. So look to take them about this time before your workout.

When to take BCAAs on non-gym days? Usually in the morning, as this can help recovery and boost muscle growth.

What is Better BCAA Capsules or BCAA Powder?

BCAA powder is definitely better than capsules because some people have a hard time swallowing capsules or might have allergy to gelatin which capsules are made of.

Is BCAA Better Before or After Workout?

Muscle building takes place post-workout, so there is some debate as to whether consuming BCAAs before a gym session has any more beneficial effects than taken after.

What is certain, is that BCAAs taken before workouts reduce fatigue and exercise-related soreness. 33

How Many Times Should You Take BCAA a Day?

Try to take BCAAs before your workout to reduce DOMS. However, if you wish to spread your daily dosage throughout the day, this may be more convenient and will not adversely affect muscle growth.

What BCAA Ratio Is Best?

As leucine is the most powerful of all the BCAAs, this should always have the largest content. The most potent ratio has been agreed as 4:1:1—four parts leucine together with one part each of valine and isoleucine.

Is BCAA a Protein?

Not exactly. Proteins contain amino acids, which may include the BCAAs of leucine, isoleucine, and valine. However, don’t automatically assume that the protein powder you are taking includes these, or in sufficient amounts to be effective.

Can BCAA Cause Hair Loss?

No. Because of the anabolic effect of BCAAs, this belief has gathered some momentum, based on the similar effects of testosterone.

However, BCAAs have been shown to improve the absorption of potassium, which in turn actually stimulates hair growth. 34
