Prevalence of Zinc Deficiency in Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis
Nutrients (2022) · Meta analysis · n=806
Pooled analyses by the IBD subgroup showed a total population of 1677 with CD, for an overall mean zinc deficiency prevalence of 54% and 95% confidence intervals (CI) ranging from 0.51 to 0.56, versus 41% (95%CI 0.38-0.45) in the UC population (n = 806).
Based on multiple meta-analyses showing 0.24-0.32 mmol/L LDL reduction. Effect specific to oat beta-glucan, not yeast forms. FDA-approved health claim at 3g dose. GI side effects more common with oat forms.
Based on meta-analyses showing reduced respiratory tract infections and improved immune markers (CD3/CD4). Effects primarily in deficient individuals. Take with food to reduce nausea risk.
