DIGESTION AND METABOLISM

In a 10‑week trial with energy restriction plus 200 mL/day kombucha, both groups lost weight/fat, but the kombucha group had extra benefits like decreased lipid accumulation product (LAP), better inflammatory cytokine profile (some markers) and improved stool / gut symptoms. (Reference)

ANTI-CANCER

Kombucha shows anti‑cancer effects via: inhibition of cancer cell proliferation; cytotoxicity toward cancer cell lines (lung, kidney, breast, colon); reduction of invasion/metastasis markers like MMP‑2 / MMP‑9; activation of antioxidant enzyme systems (e.g. via Nrf2) which help reduce oxidative stress. (Reference)

IMMUNITY

Increase in Bifidobacterium (beneficial for immunity), decrease in bacteria associated with gut inflammation; improved biochemical markers. (Reference)

ANTI-DIABETES

12 participants drank kombucha for 4 weeks; significant lowering of fasting blood glucose (from ~164 → 116 mg/dL). Placebo group showed non‑significant drop. (Reference)

SKIN

Kombucha group had a significant reduction in one pro‑oxidant marker (H₂O₂) versus control. Other oxidative and endothelial markers did not change significantly. This suggests some antioxidant activity that could translate to skin protection, since oxidative stress is a driver of skin aging. (Reference)
