Participants were randomized to either an oral dose of a Libifem at a dose of 600 mg/day or placebo over two menstrual cycles. Sex hormones, including total and free testosterone, estradiol and sex hormone binding globulin were measured at baseline and 8 weeks. The individual aspects of sexual function were measured using the Derogatis Interview for Sexual Functioning (DISF) and Female Sexual Function Index (FSFI) clinically validated questionnaires. Stress, fatigue and quality of the relationship with partner were measured along with safety and tolerability.
The results showed a significant increase in Estradiol (E2) and free testosterone, as well as an increase in sexual desire and arousal in the active group compared with the placebo group. There was also a significant increase in sexual activity for the group taking Libifem.
Libifem contains saponins that have been shown to promote a woman’s healthy sexual vitality, desire and arousal. Loss of sexual desire affects approximately one in every four women, but despite its prevalence, there are few supplement options. Libifemoffers a natural way to support female hormone estradiol that can help to boost sexual desire.
