Individuals with type 2 diabetes who drank kombucha, the fermented tea drink, for four weeks had lower fasting blood glucose levels compared to when they consumed a similar-tasting placebo drink. We hope that a much bigger trial, using the lessons we found out in this trial, might be carried out to provide a more definitive response to the effectiveness of kombucha in reducing blood glucose levels, and for this reason assist or avoid treat type 2 diabetes.”

Scientists discovered that type 2 diabetes clients who consumed kombucha over four weeks had lower fasting blood glucose levels than those who drank a placebo. This pilot research study recommends a prospective dietary intervention to help lower blood glucose levels in diabetic individuals, laying the foundation for a larger, more detailed trial.
Small pilot research study suggests larger trials are required to verify the potential advantage of fermented tea.
People with type 2 diabetes who consumed kombucha, the fermented tea drink, for 4 weeks had lower fasting blood sugar levels compared to when they took in a similar-tasting placebo beverage. This is according to arise from a scientific trial performed by scientists at Georgetown Universitys School of Health, the University of Nebraska-Lincoln and MedStar Health. This finding, from a pilot 12-person expediency trial, points to the capacity for a dietary intervention that might assist lower blood glucose levels in individuals with diabetes and also establishes the basis for a bigger trial to broaden and confirm upon these outcomes.
This finding was reported in the journal Frontiers in Nutrition on August 1, 2023.
History of Kombucha
Kombucha is a tea fermented with yeasts and bacteria and was consumed as early as 200 B.C. in China, but it did not become popular in the U.S. till the 1990s. Its appeal has actually been boosted by anecdotal claims of enhanced resistance and energy and reductions in food yearnings and swelling, however evidence of these benefits has been limited.
” Some lab and rodent research studies of kombucha have revealed pledge and one little research study in people without diabetes showed kombucha lowered blood glucose, however to our knowledge this is the very first clinical trial taking a look at impacts of kombucha in people with diabetes,” states study author Dan Merenstein, M.D., professor of Human Sciences in Georgetowns School of Health and professor of household medicine at Georgetown University School of Medicine. “A lot more research study needs to be done but this is very promising.”
Research Study Design and Results
Merenstein continued, “A strength of our trial was that we didnt inform people what to eat due to the fact that we utilized a crossover style that limited the impacts of any variability in a persons diet.”
The crossover style had one group of individuals consuming about eight ounces of kombucha or placebo beverage daily for 4 weeks and after that after a two-month period to rinse the biological effects of the beverages, the kombucha and placebo were swapped in between groups with another four weeks of consuming the beverages. Neither group was told which drink they were getting at the time.
Kombucha appeared to lower average fasting blood sugar levels after 4 weeks from 164 to 116 milligrams per deciliter while the difference after four weeks with the placebo was not statistically substantial. Guidelines from the American Diabetes Association suggested blood sugar levels before meals ought to be between 70 to 130 milligrams per deciliter.
Composition and Brand of Kombucha
The researchers likewise took a look at the makeup of fermenting micro-organisms in kombucha to identify which components might be the most active. They found that the beverage was primarily comprised of lactic acid bacteria, acetic acid germs, and a type of yeast called Dekkera, with each microbe present in about equal step; the finding was verified with RNA gene sequencing.
The kombucha used in this study was produced by Craft Kombucha, an industrial maker in the Washington, DC, location. It has been re-branded as Brindle Boxer Kombucha.
” Different studies of different brands of kombucha by different producers reveal slightly different microbial mixtures and abundances,” says Robert Hutkins, Ph.D., University of Nebraska-Lincoln and the research studys senior author. “However, the significant germs and yeasts are likely and extremely reproducible to be functionally similar in between brands and batches, which was assuring for our trial.”
The Broader Context
” An approximated 96 million Americans have pre-diabetes– and diabetes itself is the eighth leading cause of death in the U.S. as well as being a major danger aspect for heart stroke, disease, and kidney failure,” says Chagai Mendelson, M.D., lead author who was working in Merensteins laboratory at Georgetown while completing his residency at MedStar Health. “We were able to supply preliminary proof that a typical beverage might have a result on diabetes. We hope that a much larger trial, using the lessons we discovered in this trial, could be undertaken to offer a more definitive answer to the efficiency of kombucha in reducing blood glucose levels, and for this reason avoid or help deal with type 2 diabetes.”
