Impact of Canadian Haskap Berry Powder 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.
