RecruitingDietary supplementMyVitalC: Sleep and Everyday Headache ManagementSleep disturbance and recurring headaches can negatively affect daily functioning, mood, and productivity. MyVitalC (ESS60 in extra virgin olive oil) is a commercially available dietary supplement that has generated anecdotal claims related to sleep quality and headache relief; however, human data remain limited. This real-world observational study is designed to help participants evaluate whether use of MyVitalC is associated with changes in sleep disturbance and headache frequency or severity in their own daily lives. Participants will complete a four-week baseline observation period without the intervention, followed by six weeks of daily MyVitalC use, with weekly self-reported assessments. Participants serve as their own control, allowing for within-person comparison of outcomes before and during product use.
