Materials and Methods: The present randomized clinical trial was conducted on 120 participants with clinical complaints or abnormal Pap smear test results. The intervention and control groups received supplemental and placebo treatments, respectively, for 3 months after a primarily Pap smear test. The Pap smear test was also performed after the treatment and patients with abnormal results were screened by colposcopy. Data were analyzed by SPSS software and P-value less than 0.05 was considered significant.

Results: The percentage of participants in the intervention and control groups were 40% and 28.3% in the age range of 20-29, 26.7% and 41.7% in the age range of 30–39, and finally 33.3% and 30% over 40 years of age, respectively (P = 0.19). The percentage of normalization in Pap smear test result was 83.3% and 53.3% in the intervention and control groups, respectively (P < 0.001).

Conclusions: It was found that short-term usage of multi-mineral and Q10 supplements may decrease the risk of cervical cancer in women with abnormal Pap smear. However, studies with larger population and longer trial period are needed for further investigation.
