Effects and Benefits Explained
Branched-chain amino acids (BCAAs) are three of the nine essentialamino acidsneeded for survival.
They includeleucine, isoleucine, andvaline.
Since your body does not produce BCAAs, you must get them through foods or supplements.

Most people consume enough BCAAs if they eat a balanced diet.
While BCAA supplements are safe for most people, they should be taken cautiously.
This article explains how BCAAs affect your body, how to increase them, and how they can help.
It also includes side effects, warnings, and pros and cons of adding to normal BCAA levels.
Amino acids also impact metabolism.
Branched-chain amino acids are so named because of their chemical structure.
Branched-chain amino acids also convert toglucoseduring exercise more easily than other types of amino acids.
Your body uses glucose for energy.
These responses may help improve exercise performance, build muscle mass, and improve exercise recovery.
Essential vs. You must get them from foods or supplements.
BCAA Foods
you could increase BCAA intake by consuming a protein-rich diet.
Formulations vary by manufacturer and specific product.
A typical formulation is leucine, isoleucine, and valine in a 2-to-1-to-1 ratio.
There is no set value for the intake of BCAAs.
They are typically safe for most healthy individuals to take daily.
For optimal benefits, taking BCAAs before or after your workout is advised.
Supplementing with BCAAs before exercise may reduce postexercise muscle soreness and accelerate recovery time.
The findings were based on the results of participants who consumed a drink of BCAAs after their resistance workouts.
Improving Exercise Endurance
Taking BCAA supplements may improve exercise endurance and reduce exercise fatigue.
Serotonin contributes to central fatigue.
Central fatigue is the mental fatigue that occurs during extended aerobic workouts.
Those who took BCAAs also had improved energy metabolism.
There are no known interactions between BCAAs and other supplements, foods, or compounds.
This disease interferes with the proper breakdown of BCAAs.
Consuming too many BCAAs could lead to an accumulation of toxic BCAA products linked to nerve and brain symptoms.
People with a history of depression should consult their healthcare provider before using BCAA supplements.
Your healthcare provider can help you decide whether you’re able to benefit from BCAA supplements.
Consider the following pros and cons of adding BCAA supplements to your routine.
While your body needs these three amino acids for normal function, it cannot produce them.
You have to consume them through food or supplements.
There is also evidence that they can improve the signs and symptoms of people with advanced liver disease.
Consult your healthcare provider before adding BCAA supplements to your diet.
