Abstract in brief

The position stand clarifies that HMB is a naturally occurring metabolite of the amino acid leucine, with two studied forms—calcium HMB and free acid HMB—that have varying effects on blood levels.
Research indicates that consuming HMB is generally safe for at least one year, with no negative impact on glucose tolerance or insulin sensitivity, and may even improve glucose metabolism in younger adults.
HMB primarily helps increase muscle protein synthesis and reduce muscle breakdown, which can aid muscle growth and recovery, especially when taken around exercise sessions, and may improve body composition by increasing lean mass and reducing fat.]
