New Trial Will Test Whether Taurine Improves Blood Sugar and Slows Aging

Key Insight

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


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.
