BCAA (Branched-Chain Amino Acids)
What are BCAAs?
The branched-chain amino acids (BCAA) are three essential amino acids: leucine, isoleucine, and valine. BCAAs cannot be manufactured by the human body, and can be found in a variety of animal and plant source foods and dietary supplements.
Health Benefits
BCAAs act as a fuel source for skeletal muscle during times of trauma or stress, help prevent catabolism (the breakdown of muscle for energy), while encouraging protein synthesis. BCAAs are administered to victims of severe burns or serious trauma for this reason.
Branched-chain amino acids are popular with athletes and strength trainers for their anti-catabolic properties, and possible glycogen sparing activity. More research is needed, however.
Additionally, BCAAs are also used as part of treatment for hepatic encephalopathy, and may help symptoms of tardive dyskenesia and phenylketonuria. While BCAAs were once thought to help improve symptoms of amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease), it is now unclear as to whether there is any benefit. Recent studies have even shown that BCAAs may increase mortality rate in those with ALS, therefore it is not currently recommended that these individuals take BCAA supplements.
Usage Indications
Use as directed. Consult your physician before taking a BCAA supplement.
Branched-chain amino acid supplements are available in caplet, tablet, and powder form.
- Indications: BCAA supplements should not be taken by those who are pregnant/nursing, or by individuals with any serious conditions, including those of the kidney or liver. BCAAs should not be consumed in conjunction with alcohol, and care should be taken when taking in conjunction with anti-depressants (consult you physician).
