How to Support Healthy Blood Sugar: Evidence and Safe Next Steps

How to Support Healthy Blood Sugar: Evidence and Safe Next Steps: a careful evidence check

This page has been updated because earlier copy made claims that were stronger than the evidence available to us. Dietary supplements should not be presented as a way to diagnose, treat, cure, prevent, or manage diabetes.

The American Diabetes Association states that supplements are not proven to lower blood glucose or support diabetes management in people without an underlying deficiency. Treatment decisions should be made with a qualified healthcare professional.

What research can and cannot tell us

The National Center for Complementary and Integrative Health says that evidence for dietary supplements and diabetes is generally limited. Some small studies of individual ingredients have suggested possible effects, but differences in formulations, doses, participants, and study quality mean those findings do not establish that a specific commercial product works.

That distinction matters: evidence about an ingredient is not evidence that a finished product is effective, safe, or appropriate for an individual.

Safer next steps

If you have diabetes, prediabetes, symptoms of low or high blood glucose, or take medication that affects glucose, discuss changes with your clinician or pharmacist. Bring the full label of any supplement you are considering so they can assess possible interactions.

The FDA does not approve dietary supplements for safety or effectiveness before marketing. Supplements can interact with medicines and should not replace prescribed treatment or medical monitoring.
