In 2011, researchers at the Shahid Beheshti Medical University in Iran conducted a clinical study that showed that broccoli sprouts enriched sulforaphane can reduce oxidative stress reaction, HbA1c levels and improve insulin resistance in patients with type 2 diabetes

In 2017, Professor Anders Rosengren of the diabetes research center of Lund University in Sweden led his team to find that sulforaphane could inhibit the production of glucose in liver cells. Taking a dose of 150 mmol sulforaphane once a day together with metformin for 12 weeks can effectively reduce fasting blood glucose and glycosylated hemoglobin (HbA1c) levels in obese patients with type 2 diabetes mellitus with poor glycemic control. The related research is published in the are published in the sub journal of Science
