Trial summary

Haskap berries are rich in cyanidin-3-O-glucoside (C3G), which has been shown in vitro to enhance endothelial function. Previous clinical studies suggest haskap berry supplementation may improve cognition, mood, blood pressure, and athletic performance, but research is limited. Read more about this study

About this study

Official title: Impact of Haskalife(TM) Canadian Haskap Berry Powder Formulation on Hypertension and Acuity in Women's Health

Haskap berries are rich in cyanidin-3-O-glucoside (C3G), which has been shown in vitro to enhance endothelial function. Previous clinical studies suggest haskap berry supplementation may improve cognition, mood, blood pressure, and athletic performance, but research is limited. This trial aims to contribute to the growing body of evidence on the effects of haskap berry supplementation.

The trial is a 2-period, randomized, double-blinded, cross-over design lasting 16 weeks. During the first period (weeks 0-6), participants will receive either haskap berry powder or a control powder. A 4-week washout period follows (weeks 7-10), where no powder is consumed. In the second period (weeks 11-16), participants will receive the powder they did not consume in the first period.

Questions about this trial

What is this clinical trial studying?

A study testing Haskap Berry Powder in people with Hypertension and Alertness, run by University of Manitoba at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
