Berberine has the strongest evidence in this category and the worst tolerability. Chromium and cinnamon show smaller effects. Bitter melon's most recent meta-analysis found none at all.

These have a dose the research settled on, which means you can check a label against something. 11 of the 11 products below are built on two or more of them.
These turn up across the category without a settled effective dose behind them. That does not make them useless; it means a product should not cost more because it contains them.
Supplements are not diabetes treatment. NCCIH says it is "very important not to replace medical treatment for diabetes with an unproven health product". The American Diabetes Association says supplements are not proven to lower blood glucose, and it finds no benefit from them without an underlying deficiency. If you have diabetes or prediabetes, talk to your care team before adding anything, because some ingredients can change how your medicines work.
Choose single-ingredient or fully disclosed products at doses used in trials. Keep monitoring your blood sugar as your doctor advises, and review any supplement at your next check-up.
Sources:
Blood sugar supplements are scored on ingredient tier (berberine and ALA have strongest evidence), dose adequacy, cinnamon type (ceylon over cassia for long-term safety), and drug-interaction disclosure. We require clear labeling that the product is adjunctive to, not replacement for, medical diabetes management.
