I’m sure you are wondering what do bcaas do? BCAA or Branched Chain Amino Acid injections contain amino acids that have an aliphatic side-chain with a branch (a central carbon atom bound to three or more carbon atoms). There are only three BCAA’s among the proteinogenic amino acids, these are leucine, isoleucine, and valine.

Branched-chain amino acids supplements are normally considered a pre-workout supplement to boost endurance, reduce muscle soreness, and improve athletic performance. Also, one of its uses that is increasingly becoming popular is taking them to accelerate fat loss in men and women.

Leucine: It is helpful with maintaining the various muscle systems in the body. It is suspected to be the only amino acid that can enhance the production of muscle proteins for muscle growth. L-leucine has also been shown to temporarily increase the production of growth hormone and helps delay the deterioration of muscle tissue with age. 1

Isoleucine: It is an α-amino acid that is used in the biosynthesis of proteins. This BCAA has been shown to provide potential benefits for athletes because of its primary role in increasing endurance and recovery from strenuous physical activity. The body breaks down isoleucine within the muscle tissue to produce energy. Moreover, this amino acid helps to regulate blood sugar levels to stabilize energy levels.2

Valine: an amino acid that is a constituent of most proteins. It functions synergistically with the other two BCAA’s to encourage normal growth, repair bodily tissues, regulate blood sugar levels, and supply the body with energy. Valine also stimulates the central nervous system and is required to maintain mental vigor and emotional calm.3

What Do BCAAs Do and How Do Injections Work?

BCAAs form a major part of our body’s amino acid pool. They make up 35 to 40 percent of all essential amino acids in our body. While all other amino acids are broken down in the liver, BCAA’s are metabolized primarily in lean body mass tissue. They are anti-catabolic and comprise roughly 14 to 18 percent of that in the muscle cells. 

BCAAs have several functions in our body:

  • These branched-chain amino acids are used as building blocks of protein in the body, including the synthesis of new muscle cells
  • Isoleucine and valine are more beneficial in energy production and for regulating blood glucose levels 
  • This is believed to offer an energy boost during your workout because BCAAs are broken down in the muscles. 
  • BCAAs regulate blood glucose levels by stimulating cells to absorb glucose in the blood, thus preserving your muscle and liver glucose stores.5 
  • BCAAs may reduce fatigue during exercise by reducing the production of serotonin hormone.6 


BCAA Injections and Their Athletic Benefits 

BCAA’s are essential amino acids, meaning they can’t be made by your body and must be obtained from food. However, not all foods contain high-quantities of BCAAs so people usually supplement with BCAAs to get enough into their systems. 

 Thus BCAA injection is beneficial for the following purposes:

bcaa injections

  1. It is most commonly used for building muscle.     
  2.  Improves running performance by increasing stamina and delaying the sense of exhaustion that occurs during long-distance runs 
  3. Decreases exercise-induced fatigue 
  4. Alleviates muscle soreness and recovery time
  5. Reduces the rate of muscle wasting

Solid evidence supports the use of branched-chain amino acids for reducing fatigue and exertion after prolonged or intense exercise 

In a study of 30 healthy adults, squat exercises caused muscle fatigue and soreness. Those that received BCAA supplementation had less soreness in the following days, while those that did not receive supplementation showed prolonged periods of soreness.7 

Muscle fatigue after exercise also decreased with BCAA supplementation. A decline in serum BCAA levels typically causes the influx of tryptophan into the brain, which is followed by increased serotonin production and may result in fatigue.

What Do BCAAs Do For Weight Loss? 

BCAAs are not just for athletes or bodybuilders. Men and women who are struggling to lose weight can all benefit from taking BCAA supplements, Here is a quick sum-up of how you can use BCAA for weight loss:

1.BCAA Injections Energy Booster.

It offers you a quick energy boost along with all its other benefits without causing a spike in your insulin levels and breaking your fast.

2. BCAA InjectionsSuppress Food Cravings.

Food cravings are often triggered by an imbalance in your blood sugar levels. BCAA helps regulate blood glucose levels in your body and can significantly increase the uptake of glucose into muscles. Maintaining blood sugar at healthy levels prevents the dips that may cause you to binge on high sugar or high carb foods.

3. BCAA Injections Prevent Muscle Loss During Weight Loss

Muscle loss is a common problem during a weight loss problem. BCAA increases testosterone production which helps with muscle building. It also reduces the build-up of the stress hormone cortisol which otherwise causes more muscle breakdown.

4. BCAA Injections Muscle Building and Weight Loss

BCAA boosts muscle protein synthesis. Having more muscle is beneficial for weight loss as they boost your metabolism. More importantly, they also continue to burn calories even after your workout as muscle repair and recovery continues to take place.

Studies have proven that BCAAs can help women and men to lose weight rapidly. 8 If you take BCAAs, train hard, and stick to a healthy diet, you can lose more than ten pounds in a few short weeks!
