topicLactoferrin Supplementation Immune Randomized Trial
claim1 The innate immune system provides rapid, nonspecific defense through barriers, cytokines, and cells such as macrophages, dendritic cells, and NK cells, while the adaptive system generates antigen-specific and long-lasting protection via T and B lymphocytes, forming an integrated network essential for host defense [].
