Frequently Asked Questions

A: Our study team takes care of parking for study visits and will compensate you for mileage and your time in the study. Payment is typically received at the end of the study in the form of a check mailed to you ~1 month after you complete it. If you would prefer, we are happy to pay you throughout the study.

There are no direct costs to you participating in the study, though childcare and taking time off of work to travel to the study site and partake in study visits are all things you should consider when deciding to participate.

A: Completing the study will require ~13 hours of your time over the course of the 6-week study period (~14 hours over the course of 11 weeks if you opt to take part in follow-up testing). This includes a screening visit to ensure you meet the eligibility criteria, baseline testing, safety check-in visits, and post-intervention testing.

A: Yes, we can potentially adjust the timing of your sessions to allow for you to still participate. As long as you are able to travel with and consume the pills, we can work around any trips you are taking.

A: Fisetin is safe to consume at the dose we give (8mg/kg body weight over two, 3-day dosing periods). We screen potential participants for medical conditions that may make it unsafe to participate–this information is reviewed by 2 physicians.

A: Unless instructed by your provider, you should continue taking all medications as prescribed. We may ask you to refrain from consuming over-the-counter supplements before your visits, but this is only for non-prescribed supplements. We ask that you inform us of any lifestyle changes during the course of the study, including changes in medications/supplements (doses included!), exercise routine, and diet, as these could potentially impact our measurements.
