Changes of serum trace elements level in patients with alopecia areata: A meta-analysis
Jin W, Zheng H, Shan B
Published in The Journal of Dermatology
Methodology
Meta-analysis of 10 observational studies comparing serum zinc, copper, iron/ferritin, selenium and magnesium between alopecia areata patients and controls
Key Findings
Pooled analysis indicated patients with alopecia areata had significantly lower serum zinc levels than controls, while other trace elements showed no consistent difference.
Conclusions
Low serum zinc is associated with alopecia areata, supporting testing rather than blanket supplementation.
Limitations
Observational, cross-sectional data cannot establish causation or show that supplementation regrows hair; heterogeneous assays and populations.
Supplements Studied

Outcomes Measured
