Studies evaluating the effects of β‐glucans on immune and inflammatory biomarkers and infection in older adults
| Reference | Population | Intervention | Outcome vs placebo (*p < 0.05) |
|---|---|---|---|
| Fuller et al. 2017 [ 108 ] | 49 participants, mean age 56 years | 250 mg Wellmune or placebo per day (13 weeks) |
*Significant increase in LPS‐stimulated IFN‐γ production Reduction in symptomatic days (p = 0.067); Non‐significant changes in symptom severity, plasma cytokine, chemokine, and salivary IgA concentrations |
| Gaullier et al. 2016 [ 109 ] | 42 participants aged 65 years and over | 2.5 mg Lentinex or placebo per day (6 weeks) |
*Increased number of circulating B cells and prevention of decline in T cells (CD3+) Non‐significant changes in other immunological and inflammatory markers such as immunoglobulins, complement proteins, and cytokines |
