Methodology
Double-blind randomised controlled trial of 40 mg zinc sulfate versus placebo over three menstrual cycles in high school students with dysmenorrhoea.
Key Findings
Pain scores did not differ in the first cycle but were significantly better with zinc in the second and third cycles.
Conclusions
Zinc may reduce menstrual pain after sustained use, with no benefit in the first cycle.
Limitations
Single-centre adolescent sample, modest size, and self-reported pain outcomes.
Supplements Studied
Following the intervention, the mean pain scores for the treatment (2.80 ± 2.28) and placebo (3.48 ± 2.85) groups were not significantly different in the first cycle; however, scores in the treatment group were significantly better in the second and third cycles.
