White tea accelerates re-entrainment to 6-hour phase advances in mice
In a mouse model of circadian disruption, white tea markedly accelerated re-entrainment to a 6-hour phase advance. Dark and black tea improved adaptation to 6-hour phase delays. Dark tea exerted the most prominent modulation of core clock genes across tissues.

Frequently Asked Questions
Which type of tea was most effective for phase advance re-entrainment?▼
White tea markedly accelerated re-entrainment to 6-hour phase advances in mice.
Did any tea components affect circadian period in cells?▼
Yes, tea polyphenols, theophylline, and EGCG prolonged circadian periods in cells and enhanced adaptation to long cycles.
What was the study population?▼
The study used mice (animal models) and cellular models of circadian disruption.
Could these findings apply to human jet lag?▼
The authors suggest potential for mitigating jet lag, but direct human studies are needed to confirm efficacy and safety.
