Is There a Supplement to Lower Blood Sugar Safely? The Honest Answer
No supplement to lower blood sugar replaces diabetes care. The ADA finds no supplement helps glucose management without a deficiency, and some can cause lows next to diabetes drugs. A low is under 70 mg/dL for many people. Glyco Defender is a dietary supplement, makes no health claim on its label, and does not treat diabetes.

Is there a supplement to lower blood sugar that replaces treatment?
No. No supplement replaces insulin, metformin or any other prescribed treatment.
The NCCIH says it is very important not to swap medical treatment for an unproven health product (NCCIH, Diabetes and Dietary Supplements). The ADA adds that without an underlying deficiency, supplements show no proven benefit for glucose (ADA, Vitamins & Supplements).
Can a supplement to lower blood sugar cause a low?
Yes, it can, mostly when combined with diabetes medicine. A low is under 70 mg/dL for many people.
On their own, insulin, sulfonylureas and meglitinides can cause lows (NIDDK, Low Blood Glucose). Chromium may add to their effect (NIH ODS, Chromium). Signs include shaking, sweat, hunger and confusion.

FAQ01
Glyco Defender questions people ask
Can I take a supplement to lower blood sugar with metformin?
Ask your doctor or pharmacist first. Some supplements may add to the effect of diabetes drugs, which raises the risk of a low. Keep taking metformin as prescribed and share the full label with your care team before you start.
What blood sugar is too low?
For many people with diabetes, a reading under 70 mg/dL counts as a low. Signs include shaking, sweating, hunger, dizziness and confusion. Treat it with 15-20 g of fast carbs and recheck in 15 minutes. Call 911 for a faint or a seizure.
Does the FDA approve a supplement to lower blood sugar?
No. The FDA does not approve dietary supplements for safety or effectiveness before they are sold. It has also warned companies that illegally market supplements as diabetes treatments. Talk to a doctor or pharmacist before you use one.
