Past packing a probiotic punch, just how much (and how) kombucha can keep you well is a bit murky. While some studies—like one from 2014 in The Journal of Medicinal Food—have suggested kombucha tea can protect against toxic molecules called free radical and promote immunity, most of the (incredibly limited) research on the topic is done in animals.
And many of the purported health benefits stem from proponents of the beverage—not science itself.
The bottom line: Probiotics are a key part of a healthy diet, says Neola. And if you want to get them from kombucha, that's fine. Just know: If you're going to drink the raw (unpasteurised) version, make sure to buy your kombucha from a reputable company, says Gans.
She also suggests pregnant woman and kids steer clear from sipping beverage (there's a risk of bacteria, and kombucha can have trace amounts of alcohol, thanks to the fermentation process).
Remember, too: "Not all kombuchas are created equal," says Neola. "Some are loaded with added sugars." So make sure to read your label (and the serving size amount!). And if you're making your own drink, consider taking a good class beforehand, she suggests.
Not into the drink anyway? Many other foods and drinks are loaded with probiotics and antioxidants, will hydrate you, fend off disease, and keep your immune system strong. Andrews suggests trying these:
For probiotics: Sauerkraut, kimchi, kefir, and yogurt
For hydration: Water
For health benefits related to tea: Green tea
For improved immunity, skin, nails, and hair: A minimally-processed, plant-based, nutrient-dense diet
