Start with a conversation about your needs

Ask your doctor or pharmacist whether you need a supplement and which dose is appropriate. These products are listed as examples for people whose care team has recommended supplementation. Continue your prescribed diabetes treatment.

Evidence does not support routine vitamin, mineral, or herbal supplementation for blood sugar control. If your care team identifies a nutrient deficiency, they can explain how to address it. Bring your medication and supplement list so they can check for interactions.
