What Is a Blood Sugar Supplement, and What Can It Do?

Quick answer

What is a blood sugar supplement? It is a dietary supplement, often with minerals, herbs or amino acids, sold for blood sugar support. It is not a medicine, and FDA does not approve supplements before sale. No supplement is proven to treat diabetes. Sugar Defender is one example: liquid drops with chromium and a 22-ingredient blend.

The basics01

What are blood sugar supplements, and how do they differ from medicine?

They are dietary supplements marketed for blood sugar support. They are not drugs, and they follow different rules.

Supplement and medicine compared
Blood sugar supplementDiabetes medicine
FDA approval before saleNot required (FDA, Using Dietary Supplements)Required
Proven for diabetesNo proven supplement (ADA, Vitamins & Supplements)Yes, such as metformin (MedlinePlus, Metformin)

What it can do02

What does blood sugar support do?

Less than the phrase suggests. NCCIH finds no reliable evidence that any herbal supplement helps control diabetes (NCCIH, Diabetes and Dietary Supplements).

Some ingredients show small effects in small studies, at doses larger than a dropper holds. Others may add to diabetes drugs and cause lows (ADA, Vitamins & Supplements).

Keep taking prescribed medicine

Never stop or change a diabetes drug because of a supplement, and tell your care team what you take.

FAQ05

Sugar Defender questions people ask

Are blood sugar supplements regulated by the FDA?

Only after sale. FDA is not authorized to approve supplements for safety and effectiveness before they are marketed (FDA, Using Dietary Supplements).

Do natural blood sugar supplements have side effects?

Yes. Natural does not always mean safe, and supplements can interact with medicines (NIH ODS, Dietary Supplements: What You Need to Know). Tell your providers about every supplement.

Who should avoid blood sugar supplements?

Anyone on diabetes medicine, pregnant or nursing, or under 18 should ask a doctor first, as the Sugar Defender label itself advises.
