Is the calcium HMB the same as HMB

Calcium HMB (calcium beta-hydroxy beta-methylbutyrate) is a form of HMB (beta-hydroxy beta-methylbutyrate). They are chemically similar, but calcium HMB is the calcium salt form of HMB. While both are used as dietary supplements for similar purposes such as supporting muscle health and exercise performance, the choice between them may depend on individual preferences and specific formulations.
