This descriptive review had the following limitations: Zn as the primary nutrient under consideration, smaller sample sizes, and studies short in duration. Further research is needed to investigate variations in trace elements supplementation including the combination of minerals versus the addition of single minerals as supplements. Dosing regimens should also be considered when gauging efficacy. To further strengthen conclusions regarding trace element mixture administration, careful consideration of methodology and study design should be undertaken. This review has raised the question of whether or not the RDA for older adults should be re-evaluated in order to adjust for impaired absorption in Zn. Optimal Zn nutriture would improve the quality of life in older adults with wounds.

Monitoring patient risk and implementing appropriate nutritional interventions based on individual needs is vital for maintaining nutritional status, thereby optimizing patient outcomes. In conclusion, for older adults, the clinical application of supplementation of Zn along with calories, protein, and other nutrients in PIs improves outcomes, shortens healing time, and decreases comorbidities.
