What actually helps blood sugar?
The foundation is diet, movement, sleep and — for many people — medication prescribed by a doctor. On the supplement side, a few ingredients do have real research for supporting healthy glucose: Gymnema sylvestre, chromium, berberine and ginseng are the most studied.
A serious word of caution: because these ingredients can lower blood sugar, combining them with diabetes medication can risk dangerous lows (hypoglycemia). Never start a blood-sugar supplement, and never stop or change medication, without talking to your doctor and monitoring your levels.
