Age associated decline in the conversion of leucine to β-Hydroxy-β-Methylbutyrate in rats

The loss of muscle mass is considered to be a major factor contributing to strength decline during aging. β-Hydroxy-β-Methylbutyrate (HMB), a metabolite of leucine has been shown to enhance muscle protein synthesis and attenuate loss of muscle mass by multiple pathways. However, the production and regulation of endogenous levels of HMB over the... Read more

Beta-hydroxy-beta-methylbutyrate ameliorates aging effects in the dendritic tree of pyramidal neurons in the medial prefrontal cortex of both male and female rats

Beta-hydroxy-beta-methylbutyrate (HMB), a supplement commonly used to maintain muscle in elderly and clinical populations, has been unexplored in the aging brain. In both healthy aging humans and rat models, there are cognitive deficits associated with age-related dendritic shrinkage within the prefrontal cortex. The present study explores the... Read more
