Effects of β-Hydroxy β-Methylbutyrate Supplementation on Working Memory and Hippocampal Long-Term Potentiation in Rodents
TLDR: Middle-aged rats who were given varying doses of β-hydroxy β-methylbutyrate (HMB), a metabolite of the essential amino acid leucine showed improvements in memory.
However the doses are ridiculously high IMO: 225 (low), 450 (medium), and 900 (high) mg/kg body weight/day.
