Official title

The Effects of Oral Supplementation With Geranylgeraniol (GG) Sourced From Annatto on Sexual Health in Males and Females

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study will be to examine the effectiveness of Geranylgeraniol supplementation on sexual health function in males and females following an 8-week dose escalation intervention. The study will be carried out in a randomized, double-blind, placebo-controlled, parallel manner. Participants will be stratified into quartiles based on their scores on the Derogatis Interview for Sexual Functioning during screening and prior to baseline testing. Participants from each quartile will be randomly divided by into treatment or placebo conditions. Following randomization, participants will be baseline assessed on their sexual health function using a variety of questionnaires, body composition using a whole body Dual Energy X-Ray Absorptiometry scan, blood chemistry panel, and grip strength using a hand-held dynamometer. Following baseline testing, participants will undergo 8 weeks of supplementation of their respective supplement condition. Participants will be instructed to consume two servings a day (150mg total per day) from weeks 1-4. Subject will return to the study site after 4 weeks to reassess the above-mentioned parameters. Participants will then undergo a dose escalation and be instructed to consume two servings a day (300mg total per day) from week 5-8. Sexual health questionnaires and assessments of body composition, blood chemistry, and grip strength will be conducted following the week 8 to conclude the study.
