Keep reading to learn more about how BCAAs work, what they can do, and why they’re so important to your weight-loss and muscle-building journey!

BCAA or Branched Chain Amino Acids refer to three essential amino acids – leucine, isoleucine and valine. 

Amino acids are crucial to metabolism, and our body uses them to make proteins. Our body needs twenty amino acids, out of which nine are essential. The body can not produce these nine amino acids; hence we need to furnish them through diet or supplements. 

BCAAs are essential amino acids found in dietary sources like eggs, meat, and milk. However, BCAA supplements are trendy among fitness lovers, athletes and bodybuilders because of their significant role in improving exercise performance and reducing fatigue. 

The main metabolic goal of consuming BCAA supplements is to maximise the anabolic state as it is widely stated that BCAAs induce an anabolic state by stimulating muscle protein synthesis. 

If you are a beginner or a sportsperson and plan to start with BCAA supplements, the next segment will help you with a detailed overview of BCAA benefits and how they work.

Whether you’re an athlete, a fitness enthusiast, or simply looking to support your health goals, read on to learn more about the potential benefits of BCAAs and how to use them.

BCAAs and muscle growth

One of the most notable reasons to go for BCAA is that it promotes lean muscle growth. Researchers say that the amino acid leucine is a precursor for muscle protein synthesis and regulates intracellular signalling pathways in building muscle mass. Therefore, BCAA supplements with higher leucine content than isoleucine and valine might be more effective for muscle growth.

BCAAs and muscle fatigue

Fatigue is a common issue faced by active people during and post-exercise. BCAAs help reduce both mental and physical fatigue. This effect was observed during a study in which the BCAA group experienced 17% less fatigue than the placebo group.

BCAAs and DOMS (Delayed Onset of Muscle Soreness)

Supplementing with BCAA pre, during or after the workout is beneficial to reduce and relieve muscle soreness. BCAAs have been shown to decrease muscle breakdown by lowering creatine kinase levels, which may help lessen the length and severity of DOMS.

BCAAs and blood sugar levels

Clinical trials suggest that amino acids leucine and isoleucine increase glucose uptake from the blood into the muscles, thereby lowering overall blood sugar levels. Hence, branched-chain amino acid supplements may assist in maintaining healthy blood glucose levels. However, diet plays an influential role in determining the same as high fat and carb diets might cause insulin resistance. 

BCAAs and liver health

Studies suggest that BCAA supplements may also reduce fatigue and improve weakness, sleep quality, and muscle cramps in individuals with liver diseases like hepatic encephalopathy. However, if you suffer from any liver or kidney disease, medical advice from an expert is suggestible.

BCAA supplements are a popular choice among fitness enthusiasts and athletes as they are believed to help with muscle recovery, reduce muscle soreness and improve endurance. But when it comes to determining the correct dosage, it can be a bit tricky.

It’s important to note that BCAA dosage can vary from person to person depending on several factors such as their diet, workout intensity, and overall health. However, the recommended dosage is typically listed on the label of the supplement bottle. It’s important to stick to the recommended dosage and not exceed it to avoid any potential negative side effects.

When it comes to taking BCAA supplements, there are different options. Some people prefer to take it before their workout to help with endurance and performance, while others prefer to take it during their workout to help reduce muscle soreness. You can also take BCAA supplements after your workout to help with muscle recovery.

To take BCAA supplements, simply mix it with water or juice according to the instructions on the label. Alternatively, you can mix unflavoured BCAA powder with your post-workout protein shake to make it more convenient to consume.

Are there any BCAA side effects?

Absolutely! BCAA supplements are generally considered safe to consume as they contain amino acids that are essential for the body. However, there are some precautions to keep in mind.

If you have any existing medical conditions, such as liver or kidney disorders, Maple Syrup Urine Disease (MSUD), diabetes, or heart disease, it’s important to consult with your doctor before taking any BCAA supplements. This is because BCAA supplements can affect the way your body processes certain nutrients and can interact with some medications.

In rare cases, some people may experience side effects from taking BCAA supplements, such as nausea, stomach discomfort, or diarrhoea. These side effects are generally mild and can be avoided by following the recommended dosage and staying properly hydrated.

Overall, BCAA supplements are generally safe to use, but it’s important to use them responsibly and consult with a healthcare professional if you have any concerns or pre-existing medical conditions.
