L-taurine, a sulfur-containing amino acid, has been investigated in scientific studies for its potential benefits in diabetes management. Several animal studies and a limited number of small human trials suggest that taurine may help improve insulin sensitivity, reduce blood glucose levels, and mitigate some diabetes-related complications such as oxidative stress, inflammation, and neuropathy. Proposed mechanisms include taurine’s antioxidant properties, its role in regulating calcium signaling, and its effects on lipid metabolism and vascular function.

In rodent models of diabetes, taurine supplementation has been shown to decrease blood glucose and improve insulin action. Some small-scale human studies have reported mild improvements in lipid profiles and markers of oxidative stress in people with type 2 diabetes, though results are inconsistent and often not statistically significant. The doses and duration of supplementation vary widely, and larger, well-controlled clinical trials are lacking.

There is little evidence of a traditional use of taurine for diabetes; its application is rooted primarily in modern biomedical research. While the available evidence is promising, it remains preliminary. Therefore, taurine should not be considered a primary or sole therapy for diabetes, but may have adjunctive potential pending further research. As always, patients should consult healthcare professionals before starting any new supplement regimen.
