In the quest to build muscle, people seem to be unable to get enough protein. We eat copious amounts of chicken, steak, eggs, and fish to get it. In order to take advantage of different digestion rates, we isolate protein types like whey and casein and make them into powders. In addition, we isolate the individual amino acids from protein and consume them separately.

Even the most serious of lifters are left wondering why they need to take additional amino acids when they are already getting so many amino acids from the protein they are consuming. Branched-chain amino acids have been shown to have the greatest impact on muscle growth of all amino acids, and none have been shown to be more important.

Branched-chain amino acid supplements (BCAAs) have been around for longer than other supplements such as creatine and beta-alanine, but very few people are aware of their full potential for muscle growth. Researchers have recently turned their attention to branch-chain amino acids, which have been making waves within the bodybuilding community. We now know that BCAAs go far beyond simply being building blocks for muscle tissue and can affect muscle growth through pathways.

What is BCAAs?

The BCAAs, leucine, isoleucine, and valine, get their name from the branched structure they possess. All three of these BCAAs are essential; meaning that our bodies cannot synthesize them on its own, so we must get the necessary amounts through diet. Even though there are around 20 amino acids that aid in muscle growth and recovery, it is estimated that about a third of those found in muscle tissue come from this group of essential BCAAs. Therefore for ultimate muscle growth including them in your diet is essential.

Types BCAA

Powdered BCAAs

The most common way BCAAs are consumed is in powder form. BCAA powders originated as straight unflavored powders that could be mixed with protein, post-workout, or other supplements. They tasted horrible and could ruin even the best-tasting protein powders. BCAA powders are now manufactured by almost every major brand and come in a wide variety of delicious flavors.

Capsules/pills containing BCAAs

The capsule and pill form of BCAA supplements is another popular way to buy them. Due to the fact that it takes quite a few pills to get the required dosage of BCAAs and digestion is generally slower than powder, these products are generally not as common as BCAA powders. Furthermore, BCAA pills are usually larger than other supplements in pill form.

Metabolism and BCAAs

The metabolism of BCAAs is unique and significant. Most other amino acids are metabolized in the liver, but BCAAs are primarily metabolized by muscle tissue. This difference in metabolic pathways brings about varying requirements for each of the three BCAAs—leucine is broken down solely through fat pathways, valine mainly through carbohydrate pathways, and isoleucine through both. So although it may seem as though all amino acid metabolism leads to the same place—building muscle—the manner in which they are processed has an impact on their various functions within the body.

Unlike most other amino acids, BCAAs are metabolized within muscle tissue, allowing them to be oxidized (used as energy) by muscle cells to produce energy for the cells. Muscle contraction and weight lifting are powered by ATP, the primary source of energy.

It is possible for leucine, isoleucine, and valine to act as a quick energy source when they are metabolized within muscle tissue. During periods of prolonged exercise, BCAA metabolism increases significantly because the body requires more energy during these times. BCAAs are therefore extremely effective when taken at the same time as your workout.

Almost every aspect of training can be impacted by BCAAs due to their unique metabolic processes, requirements, and versatility.

Performance Enhancing BCAAs

No matter what your goals are, improving performance during training is of utmost importance. If you are an athlete, improved performance will allow you to perform better in competition. Bodybuilders also value improved performance because it leads to lifting more weight for more reps, which in turn leads to bigger muscles.

Studies have demonstrated that BCAAs possess a powerful ability to enhance performance, providing muscles with an excellent energy source and making fat oxidation more efficient in glycogen-depleted people. This enables them to sustain greater intensity and duration of training, regardless of the type of exercise.

BCAAs can enhance performance by preserving glycogen during exercise. Glycogen is a carbohydrate stored in the liver and muscles and it is the preferred fuel source for intense workouts. Research suggests that ingesting BCAAs before and while exercising can spare up to 25% of its availability. This is because they increase alanine levels which are then transformed into glucose in the liver and sent back to working muscle cells as energy. Not only does this mean you can train harder for longer, but you will also have faster recovery time for your next workout.

Hormonal effects of BCAAs

Hormones are the driving force behind muscle development, making the difference between bodybuilders, elite athletes and the average person. Anabolic hormones are particularly essential to consider for serious lifters, as they promote the synthesis of protein (muscle growth). Testosterone, insulin and growth hormone (GH) are some of the main anabolic hormones that could determine how much muscle you build. Fortunately, it has been found that BCAA intake can positively influence the release of anabolic hormones.

Testosterone is known to be one of the anabolic hormones, and it appears that BCAAs can be beneficial in helping to increase levels during pre-training. During intense training, testosterone naturally increases. Afterward, however, these levels tend to fall back to normal. Studies have uncovered that when athletes took BCAAs before their training session, they experienced elevated testosterone levels even after they were done working out; this was not seen in the control groups where levels decreased once they stopped exercising. Ultimately, this may lead to greater muscle gains from each workout.

BCAAs consumption positively impacts the body's testosterone-to-cortisol ratio, which has an impact on muscle growth. While testosterone boosts anabolism, helping to construct muscle fibers, cortisol encourages catabolism, dismantling them. BCAAs supplementation prior to resistance training is linked with increased testosterone amounts and decreased creatine kinase and cortisol levels - resulting in more tissue being built rather than breaking down.

Finally, leucine has also shown promise as a way to increase insulin sensitivity. Insulin sensitivity ensures that your body utilizes insulin effectively, which results in easier fat loss, increased muscle growth, and a lower risk of diabetes.

BCAAs are a safe and effective way to naturally manipulate hormone levels and produce greater results as natural lifters.

BCAAs & Fat loss 

The effects of BCAA consumption on fat loss are something that has been recently examined. Research has revealed that BCAAs can be beneficial for those trying to shed excess pounds. However, simply popping a few pills will not suffice; BCAAs seem to help optimize fat loss when combined with a healthful diet. Since weight loss diets typically involve reducing carbohydrates, it appears that the BCAAs ability to preserve glycogen and boost insulin sensitivity could help accelerate results.

Because BCAAs preserve muscle tissue, they are also an excellent supplement for fat loss plans. Muscle tissue loss is a serious concern when you are on a calorie-restricted diet. All of the positive effects BCAAs have on muscle growth will also serve to protect muscle during times of calorie restriction. Anything that builds muscle will also preserve muscle.

BCAAs Molecules 

The ability of BCAAs to act as signaling molecules within the body is one of their many functions. Over the past few years, this has led to some of the most exciting new research within the bodybuilding community. To understand how important this is, you must first understand how protein functions.

Amino acids have long been known to be used as the substrate for muscle tissue. This means that when people consume protein, their body takes the necessary amino acids from it in order to create muscle proteins, thus garnering its reputation as a 'building' block. However, recent research has shown BCAAs, especially leucine, can also spur the body into creating muscle by sending signals

Leucine has been revealed to play an indispensable role in stimulating muscle growth, particularly through its interactions with mTOR - short for mammalian target of rapamycin. This complex within the cells also monitors amino acid levels and is integral in moderating hypertrophy (muscle development). Though we still need to learn more about this process, evidence has demonstrated that when leucine is taken orally it triggers the mTOR pathway, initiating protein synthesis and augmenting cells' capacity to generate fresh proteins (muscle tissue). This means that, beside resistance training, we are now armed with a powerful tool to regulate growth at cellular level. An exciting discovery indeed!

People may ask: “Why not take leucine by itself without isoleucine and valine if leucine has the greatest effect on muscle growth?” It has been consistently shown that the greatest results in protein synthesis are seen when leucine, isoleucine, and valine are taken in a 2:1:1 ratio. The concentrations of the other two amino acids can be lowered when leucine is taken alone.

It is also important to note, although BCAAs can act to signal muscle growth, to act as a substrate for muscle growth, a full spectrum of amino acids must be present. In other words, you can signal your body to build muscle all you want, but if you don't have anything to build with, you won't get anywhere. So make sure you get enough whole protein every day.

BCAAs Dosage 

Before, during, and after training are the best times to ingest BCAAs. Here are effective doses.

BCAAs and bodyweight

• Before, during, and after training, 150 lbs. or less - 3 grams.
• Weight exceeding 151 lbs. - 5 grams before, during, and after training.

It is important to take in BCAAs before, during, and after training, but they are also beneficial at other times during the day. It will further increase protein synthesis and reduce muscle tissue breakdown if BCAAs are taken throughout the day in addition to those taken around training time.

Conclusion

BCAAs are a special kind of supplement - not only for their ability to build muscle, but also for the way they can impact fat loss and performance in multiple ways. The science behind them is just starting to be explored, yet already it's clear that BCAAs may turn out to be one of the most useful supplements out there. So next time someone thinks you're just another fitness enthusiast obsessed with protein intake, you can show that there's a lot more to it!
