Aloe vera enhanced glycemic control in individuals with prediabetes and type 2 diabetes when utilized as a supplement– administered orally as crushed leaves, juice, a powder, or an extract. It reduced fasting plasma glucose in those with prediabetes, and it significantly enhanced A1C in the people managing type 2 diabetes.
