ClinConnect Summary

This clinical trial is investigating how raspberry leaf tea might affect blood sugar levels after eating sugary foods. Researchers want to find out if the natural compounds in raspberry leaves can help lower the rise in blood sugar and insulin that happens after consuming sucrose, a type of sugar. The study will involve 20 healthy adults aged 18 to 65 who do not smoke, have no serious medical conditions, and are not taking certain medications or supplements that could affect their blood sugar levels.

Participants in this study will attend four visits over several months. After fasting overnight, they will drink a sugary solution mixed with either raspberry leaf tea or a control drink. Blood samples will be taken at different times to measure their blood sugar and insulin levels. To participate, individuals need to have normal blood sugar levels and meet other specific health criteria, such as not being pregnant or using herbal medicines in the past three months. This study is a great opportunity for eligible individuals to contribute to research that could help understand natural ways to manage blood sugar.
