Effects of HMB and 2-HOBA supplements on health markers in older adults: protocol for a Canadian clinical trial

Updated

Abstract

This trial aims to investigate the individual and synergistic effects of HMB and 2-HOBA supplementation on healthspan-related outcomes in healthy older adults.

  • Ageing is associated with declines in muscle mass, cognitive performance, cardiorespiratory fitness, and immune function.
  • Nutritional interventions like HMB may help mitigate muscle atrophy, while 2-HOBA could reduce neuroinflammation.
  • Chronic low-grade inflammation and oxidative stress are linked to anabolic resistance in ageing muscle.
  • Reducing inflammation may enhance the muscle-building effects of HMB.
