The Roles of Micronutrition and Nutraceuticals in Enhancing Wound Healing and Tissue Regeneration: A Systematic Review
Abstract
Micronutrients and nutraceuticals play crucial roles in wound healing and tissue regeneration, supporting various physiological processes. This review aims to synthesize and evaluate the functions of various micronutrients and nutraceuticals, emphasizing the synergistic interactions among different nutrients that facilitate wound healing processes. A thorough literature review was performed using electronic databases, including PubMed, Scopus, Web of Science, Embase, Google Scholar, and Cochrane Library, to identify molecular studies, animal models, randomized controlled trials, and observational human studies published up to January 2000. Two independent reviewers screened the articles, extracted data, and evaluated the Risk of Bias using the Risk of Bias 2 (RoB 2) tool for the 190 studies that met the inclusion criteria. Evidence suggests that bioactive compounds found in functional foods and dietary supplements can help prevent chronic conditions and promote wellness beyond basic nutrition. Vitamins A, C, and E, as well as minerals such as zinc, selenium, and iron, are essential for cell proliferation and the formation of new tissues. Additionally, nutraceuticals, including omega-3 fatty acids, glutamine, arginine, and polyphenols, exhibit anti-inflammatory and antioxidant properties, which promote healing and reduce the risk of infection. Probiotics and other bioactive compounds in nutraceuticals contribute to maintaining the balance of microbiota, reducing inflammation,…
