The details

Blood sugar: Fermented tea with a gut-health upside, but there's residual sugar (and some brands add more) — a small glass of a low-sugar brand is fine, a big sweet bottle isn't. Check the label for sugar per serving.

How to choose: Low-sugar (<5 g/serving), live cultures.

How to use it: Sip small; it's a probiotic, not a soda replacement by volume.

How to store: Fridge.

Sensible portion: ½ small bottle, few×/week
