Objective: To explore the current literature for effects of oral nutritional supplement on wound healing rates in humans. Methods: A systematic review of the literature was performed using the Medline and PubMed database following PRISMA guidelines. The PubMed database was searched using terms relating to oral nutritional supplement and wound healing from 1837 to March 2020. Study inclusion criteria were: (i) design: randomized controlled trials, clinical studies, observational studies, clinical trials; (ii) population: adults; and (iii) intervention: oral nutritional supplement. Results: The search yielded 2433 studies, 313 of which were clinical trials or clinical studies. After abstract review, 28 studies qualified to be included in the review evaluating the following supplementation categories on wound healing: protein and amino acids (10), mineral, vitamin and antioxidants (9), probiotics (1), and mixed nutrients (8). Arginine and omega-3 supplement were shown to improve wound healing in head and neck cancer patients with surgical wounds by decreasing incidence of postoperative complications and reducing length of hospital stay. Mineral, vitamins, and antioxidants enriched supplements were more beneficial in increasing wound healing than non-enriched protein supplement for diabetic foot and pressure ulcers. Conclusions: Supplementation of a variety of nutrients had variable effects on improving wound healing in different types of wounds. However, further research on the impact of nutritional supplements on surgical wound healing is necessary. The impact of multiple nutrient formulations may also need to be further evaluated for efficacy.
