Masters athletes (MA) are generally considered healthier than their sedentary peers. However, the prevalence of chronic conditions in any population increases with age. Treatments involve pharmacological and non-pharmacological interventions. A substantial proportion of the general population also use dietary supplements (DS). This raises questions about the potential for drug-nutrient interactions which may lead to adverse effects. We sought to determine the potential for drug-nutrient interactions MA may be exposed to by examining the prevalence of chronic conditions treated with medications and their DS use.

Common conditions in MA include hypertension, hyperlipidemia, asthma, osteoarthritis, depression and anxiety. Treatments may involve prescribed medications. Few recent studies were identified on DS use; however, indications are for around 60% prevalence of supplement usage.

The higher prevalence of DS use by MA may result in drug-nutrient interactions that impact the effectiveness and safety of prescribed medications for chronic conditions.
