Description of intervention(s) / exposure
The clinical study will be conducted as a randomized, double-blind, placebo-controlled trial. Sixty adult male participants (18-65 years old) will be recruited at the Clinic of Endocrinology, Diabetes and Metabolic Disease, University Clinical Center of Serbia, Belgrade. The study inclusion criteria will be as follows: confirmed diabetes type 1 (T1D) for less than 15 years, intensive insulin substitution or subcutaneous insulin infusion therapy, body mass index less than 35 kg/m² and informed consent signed. The participants from the intervention group will take orally 36 mg (83 µM) of activated sulforaphane precursor, glucoraphanin (sulforaphane glucosinolate) daily for three months. Intervention capsules contain 18 mg glucoraphanin from broccoli seeds and 2.8 µM myrosinase (activating enzyme). The placebo group will take capsules with microcrystalline cellulose (placebo). All participants will be asked to take 2 capsules after breakfast, Taking capsules will be monitored once per week through phone interviews. Participants will be asked to bring back non-used capsules, and study compliance will be assessed by capsules accountability,

Summary
Brief summary
Project is exploring a new approach in the prevention and treatment of type 1 diabetes by suppressing a newly discovered type of iron-dependent cell death called ferroptosis, through the use of specific natural compound sulforaphane, present in cruciferous vegetables, such as broccoli. We aimed to examine whether such an approach will preserving the functional population of pancreatic ß-cells, the key cells for insulin production, as well as the function of cells in tissues affected by diabetes.
