Kombucha Tea Blend
Also known as: Kombucha Tea Blend, Kefir Tea, Fermented Tea, Kombucha
Overview
Kombucha is a fermented tea beverage made from sweetened black or green tea and a symbiotic culture of bacteria and yeast (SCOBY). The fermentation typically lasts 7 to 10 days, producing a carbonated drink rich in organic acids, vitamins, and phenolic compounds. Known for its potential health benefits, kombucha is often marketed for its antioxidant, antimicrobial, and various metabolic advantages; however, research is primarily based on animal models rather than substantial human clinical trials.
Benefits
Evidence primarily from animal studies indicates that kombucha can lower blood glucose levels and improve lipid profiles by increasing high-density lipoprotein cholesterol (HDL-c) while decreasing low-density lipoprotein cholesterol (LDL-c) and triglycerides. However, the strength of this evidence is moderate, being based largely on animal studies, with an urgent call for more comprehensive human trials to support these claims. The lack of robust data limits the definitive conclusions regarding its efficacy in the human population.
How it works
Kombucha may exert its effects through the modulation of glucose and lipid metabolism, possibly involving the action of bioactive compounds produced during fermentation. These compounds include organic acids like acetic acid, which may enhance insulin sensitivity, while antioxidant properties could help reduce oxidative stress in the body.
Side effects
Kombucha is generally safe for most adults but may pose risks for specific populations, including infants, pregnant women, children under four, those with kidney failure, and individuals living with HIV. Adverse effects may include gastrointestinal upset, allergic reactions, and the potential for contamination if improperly brewed. Consuming excessive amounts can lead to acidosis due to high levels of organic acids. Those on medication or with liver problems should consult a healthcare provider before consumption.
Dosage
Recommended dosages of kombucha vary; however, starting with 4 to 8 ounces, one to three times daily is common. It's advisable to gradually increase intake, observing how the body reacts. Kombucha should be consumed after meals for optimal digestion and absorption. Users should take care to ensure that the product is properly fermented to reduce risks of contamination, and it is advisable not to exceed 16 ounces per day without medical advice.
