Abstract:
Individuals who take medications may benefit from using vitamin and/or mineral supplements (VMS) yet excess supplementation can lead to overuse (daily intake exceeding the tolerable upper intake level (UL)). This study assessed VMS use of medically complex, community-living, older adults. A chart review of 229 patients ≥50 years with new medication assessments between 2014 and 2017 indicated that 76.9% of patients used ≥1 VMS daily. The UL for one or more nutrients was exceeded by 39.8% of supplement users.
