Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults over 30 years old with a clinical diagnosis of Type 2 diabetes for at least 6 months and specific HbA1c levels.
✕Probably not a fit
Patients with chronic renal failure, recent myocardial infarction, or those currently using certain medications or supplements may not benefit from this study.

What this trial studies
This clinical trial investigates the impact of taurine, a semi-essential amino acid, on glycemic control, lipid levels, and inflammation in individuals diagnosed with Type 2 diabetes mellitus (DM2). A total of 94 participants will be randomly assigned to receive either taurine or a placebo for 12 weeks, with various blood and urine tests conducted to assess changes in key health markers. The study aims to determine if taurine can improve health outcomes for those who struggle to meet glycemic targets with conventional treatments. Participants will also be monitored for adverse effects throughout the trial.
Why it matters
Potential benefit: If successful, this study could provide a new adjunctive treatment option for individuals with Type 2 diabetes who have difficulty achieving glycemic control.
How similar studies have gone: While pre-clinical studies suggest taurine may be beneficial, there are currently no well-conducted clinical studies evaluating its effects on glycated hemoglobin in humans, making this approach novel.
