ClinConnect Summary

This clinical trial is looking at whether drinking a special kind of tea—English breakfast tea mixed with fermented seaweed—can help improve heart and blood vessel health in women who have gone through menopause. Because women’s risk for heart problems often increases after menopause, researchers want to see if the natural compounds in seaweed can lower this risk by improving things like blood pressure and blood vessel function. The tea has been specially made to taste like regular English breakfast tea but contains added seaweed that may offer these heart benefits.

To join the study, you need to be a woman who has not had a menstrual period for at least a year (meaning you are postmenopausal), regularly drinks tea at least once a week, and is willing to drink three cups of this special tea every day for eight weeks. The study is for women with a body weight in a healthy to moderately high range and without a history of serious heart disease, diabetes, cancer, or other specific health issues. Participants will be asked to drink the tea daily and have their heart and blood vessel health checked before and after the eight weeks to see if the tea makes a difference. This study could help find a simple, enjoyable way to support heart health in many women after menopause.
