Managing blood sugar isn’t just about numbers on a glucose monitor.
It’s about having steady energy throughout the day, fewer cravings, better sleep, and peace of mind.
For millions of people dealing with prediabetes or diabetes, small daily habits can make a real difference — and choosing the right tea is one of the simplest places to start.
Certain teas contain powerful plant compounds that help support healthy glucose levels, improve insulin sensitivity, and reduce post-meal blood sugar spikes. Below are five of the best teas for blood sugar, backed by research and widely used as part of daily wellness routines in the U.S.
