What are BCAAs?

Branched-chain amino acids (BCAAs) are a group of 3 essential amino acids: leucine, isoleucine, and valine. BCAA supplements are commonly used to boost muscle growth and enhance exercise performance, according to Healthline [1]. They may also help with weight loss and reduce fatigue after exercise.

What’s the Problem?

Despite their purported benefits, a recent class action lawsuit alleges that BCAA supplements actually decrease protein synthesis and are “wholly incapable of building muscle on their own.”

Studies have found that BCAAs contain only 3 of the 9 essential amino acids the body needs to build muscle, and may increase the risk of severe, potentially life-threatening side effects.

BCAA Side Effects

Excessive use of BCAA supplements has been linked to:

  • Liver injury
  • Non-alcoholic fatty liver disease
  • Unhealthy drop in blood pressure (hypotension)
  • Buildup of uric acid in the blood
  • Joint inflammation
  • Gout
  • Increased insulin resistance
  • Gastrointestinal distress
  • Fatigue
  • Loss of coordination
  • Nausea
  • Headache
  • And more

Class Action Alleges Nutrabolt Xtend BCAAs Do Not Support Muscle Growth

A class action lawsuit recently filed in New York alleges that Xtend BCAA dietary supplements do not support muscle growth or recovery, and can harm muscle protein synthesis. The suit further claims that Woodbolt Distribution, doing business as Nutrabolt, markets its Xtend BCAA supplement as able to support muscle growth and recovery;

However, independent research has found that BCAA supplements actually decrease muscle protein synthesis and are wholly incapable of building muscle on their own. Products named in the complaint include:

  • Xtend Original BCAAs
  • Xtend Elite BCAAs
  • Xtend Hydrasport BCAAs
  • Xtend Ripped BCAAs
  • Xtend Energy BCAAs
  • Xtend Free BCAAs
  • Xtend Hydration + BCAAs in ready-to-drink bottles

BCAA Supplements May Have ‘Detrimental Effects’ on Health, Lifespan: Study

A 2019 study from the University of Sydney determined that although BCAAs are highly effective at growing muscle, excessive intake of supplements in the form of pre-mixed protein powders, shakes, and supplements may do more harm to the health of the user than good.

“While diets high in protein and low in carbohydrates were shown to be beneficial for reproductive function, they had detrimental effects for health in mid-late life, and also led to a shortened lifespan,” Solon-Biet said. “What this new research has shown is that amino acid balance is important—it’s best to vary sources of protein to ensure you’re getting the best amino acid balance.”

As reported in the journal Nature Metabolism [2.], lead researcher Samantha Solon-Biet and colleagues found that although BCAAs exert muscle-building benefits, excessive intake may reduce lifespan, increase appetite, lead to weight gain, and hurt mood.

Excessive consumption of any protein is not ideal and excessive intake of protein powders or shakes could even be dangerous, the researchers found.
