Effect of regular green tea () kombucha consumption on oxidative stress and endothelial health in individuals with excess body weight: a randomized controlled trial.
RCT evaluating the effect of daily consumption of 200 ml green tea kombucha on oxidative stress and endothelial health in individuals with excess body weight over 10 weeks. Kombucha consumption significantly reduced hydrogen peroxide levels, suggesting antioxidant properties, but did not alter other markers of oxidative stress and endothelial health.
Kombucha: a systematic review of the empirical evidence of human health benefit.
Systematic review of empirical evidence on the health benefits of kombucha. Only one study was found reporting results on human subjects, highlighting the need for more human clinical trials.
Kombucha: a systematic review of the clinical evidence.
Systematic review evaluating the efficacy and safety of kombucha. No clinical studies were found on its efficacy, but several case reports and series suggest potential safety concerns, including liver damage, metabolic acidosis, and cutaneous anthrax infections. One fatality was reported.
Modulating the human gut microbiome and health markers through kombucha consumption: a controlled clinical study.
An eight-week clinical trial investigated the effects of a four-week kombucha supplement in healthy individuals on a Western diet. The study found no significant changes in biochemical parameters or inflammation markers, but noted increases in fasting insulin and HOMA-IR in the kombucha group and reductions in HDL cholesterol in the control group. Kombucha consumption modestly impacted gut microbiome composition.
Sensory Assessment, Nutritional and Antibacterial Effect of Kombucha Incorporated with Citrus grandis (L.) Extract
The study developed a kombucha beverage incorporating Citrus grandis extracts to enhance its nutritional profile. The formulations exhibited significant antioxidant properties, high vitamin C content, and essential minerals, suggesting potential health benefits and commercial viability.
Regular black tea kombucha consumption is associated with improved insulin resistance and increased ADIPOQ expression in adults with obesity: a pre-post clinical trial.
Pre-post clinical trial evaluating the effects of 200 mL black tea kombucha consumption over 8 weeks in individuals with and without obesity. Significant changes were observed in inflammatory and oxidative stress markers, with differences in metabolic responses based on obesity status. Upregulation of ADIPOQ gene expression was noted, suggesting potential metabolic benefits.
