Zinc Supplementation Enhances Immune Function and Reduces Inflammation in Adults: A Six-Month Study

Abstract Summary Objective: This study investigates the impact of zinc supplementation on immune function and inflammation markers in adults.

Context: Zinc is an essential mineral known for its role in immune function and anti-inflammatory properties. This study aims to evaluate the effects of zinc supplementation on immune response and inflammation in healthy adults.

Methods Used Approach: The study employs a randomized, double-blind, placebo-controlled trial. Participants were divided into two groups, receiving either zinc supplements or a placebo for six months. Immune function and inflammation markers were assessed.

Data Collection: Immune function was measured using lymphocyte count, NK cell activity, and antibody response at baseline, three months, and six months. Inflammation markers were evaluated through blood tests for CRP, IL-6, and TNF-α. The differences between the zinc and placebo groups were analyzed.

Researchers' Summary of Findings Impact on Health: The research indicates that zinc supplementation is associated with enhanced immune function, including higher lymphocyte counts and improved NK cell activity. Participants in the zinc group also showed reduced inflammation markers.

Health Implications: Regular zinc supplementation may support immune health by enhancing immune response and reducing inflammation, potentially lowering the risk of infections and inflammatory diseases in healthy adults.
