Test how grape-based drinks affect blood flow response
Part of Heart & circulation clinical trials.
This study tests whether a grape product (“Chardonnay Marc”) can change how your blood vessels respond to stress, measured with a finger sensor. It may help researchers understand how diet influences circulation in people with a low baseline blood-flow response.
Summary written for real people, not researchers, by Clin2.

This study tests if consuming a powder made from chardonnay grape pomace (the leftover skins and seeds from winemaking) can improve gut and heart health in postmenopausal women. You may be a good fit if you are between 45-70, have gone through menopause, and have higher levels of blood fats called triglycerides.
This study tests whether taking a daily cocoa flavanol supplement (a natural compound from cocoa beans) affects your body's health, like blood flow and inflammation. You would take either the supplement or a low-flavanol control for the study period and give blood samples at the start and end.
This study tests whether early-life stress affects blood vessel function in young adults by looking at a type of cell stress called oxidative stress. It involves measuring how well your blood vessels work and may help understand why some people have higher heart risks.
This study tests whether a ginger-based drink can reduce inflammation and oxidative stress (a type of cell damage) and improve blood vessel health. It may help adults who are overweight but otherwise healthy.
This study looks at whether following a Mediterranean diet and eating foods rich in polyphenols (natural compounds found in fruits, vegetables, and chocolate) can help reduce oxidative stress during pregnancy. You may be able to join if you are in early pregnancy and willing to make some dietary changes.
This study tests whether eating California grapes can improve gut health and heart health in overweight or obese women who have been through menopause and may have type 2 diabetes or metabolic syndrome. You would need to eat grapes daily and provide blood and stool samples.
