Branched Chain Amino Acids

Branched Chain Amino Acids are a supplement consisting primarily of three amino acids: leucine, isoleucine, and valine. BCAA supplements can help to increase muscle mass during intense exercise or weight-loss diets.


Branched chain amino acids (BCAAs) have recently gained much attention as a super-sports supplement that may help you develop muscle and recover faster between sessions. However, recent research suggests that supplementing with these necessary amino acids may boost liver function and keep you looking trim outside of the gym. These aren’t the only advantages of BCAAs.

Are you interested in learning more about how increasing your consumption might benefit your health? Let’s look at some of the BCAA advantages and disadvantages, as well as how to acquire more of these vital amino acids in your diet.

What Are BCAAs?

Branched chain amino acids (BCAAs) are a popular supplement that is often promoted as a rapid solution to improve athletic performance. So, what exactly are BCAA supplements, and how do they work?

Any form of amino acid with a chain that branches off to one side is included in the official BCAA definition. This group has three amino acids: leucine, isoleucine, and valine. All three are considered essential amino acids, which means your body cannot generate them independently and must rely on dietary sources to receive them.

BCAAs, unlike most other amino acids, are broken down in the muscle rather than the liver and play an important role in energy generation during exercise. They are also essential for various other elements of health, including maintaining proper blood sugar levels and muscular growth.

BCAA supplementation has been extensively explored in recent years, with a flurry of new studies uncovering a lengthy list of advantages. For example, BCAA powder may help stimulate muscle development, ease post-workout recovery, improve liver health, reduce muscle loss, improve athletic performance, and even help you lose weight, according to studies.


Branched chain amino acids (BCAAs) and essential amino acids (EAAs) are two of the most popular buzzwords in nutrition these days, with a continual stream of new research revealing how important these nutrients are to one’s health. But what exactly are amino acids, and how do branched chain amino acids vary from essential amino acids?

Glycine, tyrosine, cysteine, and other amino acids are among the 20 essential for the body to grow, develop, and operate effectively. Eleven of these amino acids are classified as non-essential amino acids, which means your body may manufacture them. On the other hand, essential amino acids are unable to be produced by the body and must be obtained from the diet.

Branched chain amino acids have a distinct chemical structure that distinguishes them from other amino acids due to their side chain. All three BCAAs, including leucine, isoleucine, and valine, are considered essential amino acids, which means they must be obtained through meals or supplements to ensure that you receive enough.

Health Advantages

1. It promotes muscle growth

BCAA’s capacity to boost muscle development is one of its most amazing features for both women and men. If you read any of the BCAA reviews online, you’ll almost certainly find that they help bodybuilders, athletes, and even ordinary gym-goers grow muscle.

For example, according to a research published in Frontiers Physiology, persons who took a BCAA supplement after resistance exercise had 22% greater muscle protein synthesis than a control group. However, keep in mind that having a healthy combination of all nine necessary amino acids, rather than simply branched chain amino acids, is crucial for muscle building.

2. Reduces the amount of time it takes to recover

BCAAs may be able to aid if you’re continuously hurting after working out. BCAAs have been shown in studies to minimize protein breakdown and muscle damage during exercise, reducing discomfort and speeding up muscle recovery. Furthermore, one Japanese research discovered that using a BCAA pre-workout supplement decreased muscular soreness and tiredness. As a result, it’s no surprise that a review of eight research published in Nutrition found that BCAA supplementation is a more effective technique for speeding up recovery than rest after periods of severe exercise.

3. Improves the health of the liver

According to some studies, branched chain amino acids may help persons with liver diseases such as cirrhosis, hepatic encephalopathy, and liver cancer. For example, one evaluation of 11 research revealed that consuming BCAAs improved liver function in patients following liver surgery, reduced the likelihood of complications, the length of hospital stays, and the patient’s possible financial burden. In addition, according to several studies, branched chain amino acids may also protect against liver cancer and help with hepatic encephalopathy.

4. Helps to prevent muscle loss

Sarcopenia, or the loss of muscle mass, is common as we grow older and is a typical component of the aging process. Unfortunately, muscle loss is also a typical side effect of long-term illnesses such as cancer. Fortunately, including a high-BCAA diet in your diet is a simple and effective method to begin slowing muscle loss and improving your body composition.

According to a research published in the journal Clinical Science, the infusion of branched chain amino acids was beneficial in reducing muscle breakdown in humans. Other animal investigations have supported similar findings, with BCAAs being able to prevent skeletal muscle degeneration in rats.

5. Helps athletes perform better

BCAA supplements might help you boost your athletic performance on the field or in the gym. It can improve muscle development and minimize discomfort while also improving strength and performance. Supplementing with leucine daily for 12 weeks during a resistance training program, for example, resulted in considerable gains in strength performance, according to a research done by Leeds Metropolitan University in the United Kingdom.

6. Helps you lose weight

More and more recent studies have shown a direct correlation between BCAA supplementation and weight reduction. When paired with resistance exercise, a branched chain amino acid supplement improved lean body mass and reduced body fat more efficiently than whey protein in 36 men. Similarly, in rats, long-term treatment with leucine reduced body fat without changing protein status, according to a research.

Supplements divided into many categories

So, what’s the finest BCAA powder to use if you want to increase muscle mass and push your training to the next level? For a fast and handy intake of additional protein, several BCAA capsules, powders, and tablets are on the market. However, a protein powder may be a better alternative since it provides all nine necessary amino acids and all three branched chain amino acids that your body needs.

Whey protein and protein powder derived from bone broth are two of the finest amino acid supplements since they provide a greater spectrum of essential amino acids and BCAAs. Another alternative is a brown rice protein powder, which is a vegan BCAA source with a full complement of all 20 amino acids. Make a great BCAA drink or smoothie with any of these alternatives with your favorite fruits, vegetables, and superfood mix-ins.

BCAAs may also be obtained from dietary sources. BCAAs are found in the largest amounts in meat, poultry, and fish, followed by other protein sources such as legumes, dairy products, tempeh, and eggs.

Women’s and Men’s BCAA Supplements

BCAAs may be found in various forms, including pills, powders, tablets, and capsules. Other protein powders that include BCAAs include bone broth protein powder, whey protein powder, and brown rice protein powder.

Branched chain amino acids have been shown in studies to be advantageous for both men and women since they may aid muscle building, weight reduction, and athletic performance. As a result, the ideal BCAA for women and men may differ depending on individual tastes rather than gender.

Regardless of whose form you choose, the best BCAA for men and women should always be bought from a trustworthy supplier to ensure that you receive the greatest value for your money. In addition, fillers and additives, such as artificial sweeteners, thickeners, milk solids, and dextrins should be avoided in the finest BCAA supplement products.

Recommendations for Dosage

You may be wondering whether BCAA should be taken before or after a workout. When is the ideal time to take BCAA if you don’t work out every day?

When it comes to using BCAA supplements, most experts advocate taking them before and after exercises to get the most out of your workout. Another alternative is to take them immediately before bedtime, which can aid muscle healing and lessen pain. BCAAs should be taken over a longer period for optimal outcomes, which means you should take them both on days when you work out and when you don’t.

The suggested BCAA dose varies, but it’s usually about 91 milligrams per pound of body weight. For example, if you weigh 150 pounds, you’ll need roughly 13,650 milligrams (13.7 grams) of BCAAs each day. This amount should ideally be divided into many smaller doses throughout the day, such as before and after exercising.


You can add BCAA powder to your favorite dishes for a sweet treat or combine it into a BCAA drink before hitting the gym by choosing a BCAA powder over pills or tablets.

Side Effects and Risks

BCAAs are usually deemed safe and may be eaten in dosages up to 35 grams per day with no chance of BCAA adverse effects. However, there are certain disadvantages to BCAA supplementation, and supplementation may not be appropriate for everyone.

BCAA supplementation is not recommended for people with amyotrophic lateral sclerosis (ALS) since it may affect nerve cells. Furthermore, patients with maple syrup urine disease (MSUD) cannot break down branched chain amino acids adequately and should consume them in moderation to prevent any possible BCAA adverse effects. As a consequence of this hereditary disorder, weight loss, exhaustion, diarrhea, vomiting, seizures, coma, and even death are all possible symptoms.


The history of branched chain amino acids may be traced back to the 1800s, beginning with scientist Joseph L. Proust’s discovery of leucine in 1818. Nearly a century later, in 1901, valine was found, and isoleucine was identified just a few years after, in 1903.

The Institute of Medicine of the United States developed the first official daily allowances for all three branched chain amino acids in 2002 to calculate the approximate quantity required by the body. A slew of research followed, confirming the relationship between BCAAs and athletic performance.

BCAAs are now often utilized to treat a range of medical disorders, including burns, trauma, and sepsis, which is an infection-related consequence. In addition, BCAA supplementation may also be useful for other illnesses such as diabetes and liver disease.
