But there are few valid medical studies of kombucha tea's role in human health. And there are risks to think about. Kombucha tea has caused stomach upset, infections and allergic reactions in some people. Kombucha tea is often made (brewed) in homes under unclean conditions.
You can drink kombucha daily in moderation (around 4 oz), but daily overconsumption risks headaches, nausea, excess sugar/calories, or potential lactic acidosis, especially from homemade batches with contamination risks, while its caffeine, alcohol, and acidity make it unsuitable for pregnant/breastfeeding individuals, children, or those with compromised immunity or certain health conditions.
Fermented foods

Most kombucha side effects happen for one of two reasons: The amount of beverage consumed. Because this is a probiotic drink, drinking too much might lead to an upset digestive system. And because sugar is involved, overconsumption can also lead to too much sugar intake.
Fungal and bacterial contaminants are common, with more than 20 cases of cutaneous anthrax as well as liver damage and allergic reactions reported. Other harmful contaminants found in kombucha include such molds as Aspergillus. Excessive consumption has resulted in life-threatening metabolic acidosis.
One of the main benefits of kombucha is that it contains probiotics, which are healthy bacteria that support your gut health. If you drink it in moderation, kombucha can help make you poop if you're experiencing constipation and support the immune system.
Narrow stools that happen now and then probably are harmless. But in some cases, narrow stools — especially if pencil thin — may be a sign that the colon is narrowing or has a blockage.
