The Effects of CBD Isolate on Menstrual-Related Symptoms

A Randomized, Open-Label Trial on the Effects of Cannabidiol Isolate on Menstrual-Related Symptoms

The goal of this open-label clinical trial is to compared two different doses for treating menstrual-related symptoms in individuals who experience regular menstrual cycles (occurring for 4-8 days every 21-28 days). The main question it aims to answer is:

(1) if there are changes in menstrual-related symptoms from baseline compared to all 3-months of cannabidiol (CBD) isolate consumption.

Participants will complete a monthly baseline measure after they stop menstruating followed by taking CBD twice daily (BID) for five days for three menstrual cycles and complete the same measures. Researchers will compare 160mg of daily CBD isolate to 320mg of CBD isolate to see if there are differential effects on menstrual-related symptoms (MRS).
