Leucine for Dogs: Muscle Support, Metabolic Signalling & Healthy Ageing
Leucine is the most potent dietary activator of the mTOR signalling pathway — the master cellular switch that initiates muscle protein synthesis in every mammalian species studied, including dogs. As dogs age, their ability to maintain lean muscle mass declines, leading to sarcopenia — the progressive loss of muscle that visibly thins the hindquarters and reduces mobility. This evidence-based guide explains how L-leucine at 30 mg per chewy in Bonza Boost Bioactive Bites supports muscle maintenance, metabolic health, cognitive function and intestinal integrity through the gut–metabolic axis.
