## Summary

This is a protocol, not results, for a trial giving healthcare workers 3 grams of taurine daily for six months. Researchers want to see if it lowers HbA1c (a long-term blood sugar marker) and improves PhenoAge, a biological age estimate. The study uses a smart adaptive design that can stop early if taurine clearly works or clearly fails.

## Practical Takeaway

No findings yet, but this trial will help clarify whether taurine actually moves the needle on metabolic aging.
