Branched-chain amino acids and the risk of amyotrophic lateral sclerosis

Takeaway

  • Branched-chain amino acids (BCAAs) are not associated with increased risk of amyotrophic lateral sclerosis (ALS).

Why this matters

  • There is limited and conflicting data on the role of BCAAs in ALS, but this study suggests that higher pre-diagnostic plasma BCAA levels are not a risk factor for ALS.
