    McFarlin BK, Carpenter KC, Davidson T, McFarlin MA

    Published in Journal of Dietary Supplements

    Methodology

    Randomized double-blind placebo-controlled trial of baker's yeast beta-glucan measuring monocyte and NK cell markers and upper respiratory symptoms.

    Key Findings

    Beta-glucan reduced upper respiratory symptom days and altered innate immune cell markers versus placebo.

    Conclusions

    Beta-glucan modestly supports innate immune surveillance including NK-associated activity.

    Limitations

    Small sample; symptom outcomes self-reported; industry funded.

    Outcomes Measured

    Natural Killer Cell Activity

    Beta-glucan reduced upper respiratory symptom days and altered innate immune cell markers versus placebo
