Immunity
Supplements studied for immunity.
Overview
Six supplements are indexed for immunity (19 studies). Reishi has the strongest profile (medium effect size, medium evidence, medium trust, WA 60; 4 studies), though the available summary is brief. Glutamine (WA 40; very low effect size, high evidence, medium trust; 5 studies) may support gut barrier integrity during hard exercise but does not reliably improve overall immune function in most clinical studies.
Vitamin D, Quercetin, and Blueberry (WA 44; low effect size, low evidence, medium trust) have low or insufficient evidence ratings. Blueberry consumption around intense exercise may reduce post-exercise oxidative stress and support recovery markers in one study.
Overall, general "immunity" supplement evidence is mixed and outcome-specific. See the heatmap and evidence reviews below.
