Truth Behind BCAAs: Performance Boosters or Just Expensive Placebos?
What are branched-chain amino acids?
Nutrients that are typically obtained from the proteins found in food are known as branched-chain amino acids.
What are the applications of amino acids with branched chains?
When it comes to combating fatigue, improving concentration and athletic performance, and reducing the loss of muscle mass that occurs during exercise, branched-chain amino acids have been proposed as candidates. ALS, brain problems associated with liver disease, tardive dyskinesia, loss of appetite in the elderly with kidney failure or cancer patients, McArdle’s disease, and spinocerebellar degeneration are some of the other conditions that can be treated with these medications. Lastly, they are utilized to slow the loss of muscle mass in individuals who are bedridden.
The European Food Safety Authority (EFSA) has not given its approval to the claims that branched-chain amino acids are responsible for the following substances:
help repair and promote the recovery and maintenance of muscle tissue after exercise; help increase and develop muscles and their strength; help recovery from muscle fatigue; reduce muscle breakdown after exercise; exert an anabolic effect on protein metabolism after exercise; improve mental performance after exercise; increase protein synthesis as a vital process in muscle production; maintain optimal immune function during exercise and provide essential fuel for the immune system; reduce perceived fatigue during exercise and make physical activity easier; reduce the loss of muscle strength during exercise at high altitude and increase the maintenance of muscle strength after being at high altitude.
Indications of caution and potential contraindications for the use of branched-chain amino acids
The absorption of levodopa may be decreased by branched-chain amino acids, and the effects of antidiabetic medications may be enhanced by these amino acids. It is possible that the concurrent consumption of diazoxide, corticosteroids, or thyroid medications will reduce the effectiveness of these medications.
When it comes to taking branched-chain amino acids orally, it is generally not considered to be dangerous; however, it can cause side effects such as fatigue and loss of coordination. Because of this, it is best to take them with caution if you have to engage in activities that require good motor coordination, such as driving.
Cases of amyotrophic lateral sclerosis (ALS), branched-chain ketoaciduria, chronic alcoholism, hypoglycemia in children, and scheduled surgical procedures are all potential contraindications for the consumption of branched-chain amino acids.
