NATURE’S OWN –
Oct. 8, 2025 – Compounds in green tea can reprogram muscle metabolism to boost insulin sensitivity and glucose tolerance, according to new findings that further our understanding of why this ancient drink has long been linked to protection against obesity. Green tea has long been linked with improved blood sugar control and reduced risk of metabolic diseases, but much of that evidence stems from animal studies undertaken in cool laboratory environments. Those conditions can artificially trigger calorie burn and mask the true physiological effects being tested. Researchers from Cruzeiro do Sul University wanted to remove that bias to see if green tea still delivered metabolic benefits in obesity models.
While the mice dose of green tea equated to around three cups a day, the scientists warn that there’s more nuance involved. Not all commercial green tea products meet the same quality standards that were used in the laboratory-grade extract, and dosage, bioavailability and polyphenol content can vary widely between preparations.
