Recently, there was an article published in New Scientist about a study conducted at the University of Pennsylvania. The researchers found that brain-injured mice developed lower levels of certain amino acids known as BCAAs within a few days of being injured. The low-BCAA mice were divided into 2 groups, with one group getting plain water and the other group getting BCAA-enriched water. The mice in the 2nd group were reported to have normalized BCAA levels and performed better on a learning task. The research dovetails with similar findings from scientists at the University of Pavia in Italy.
