1. Detoxification Kombucha contains substantial amounts of glucuronic acid (GA). GA is well known as a detoxicant. In the body it combines with toxins like pharmaceuticals and environmental pollutants. It then converts them into compounds that are soluble and the body can excrete. Drinking kombucha may also help prevent tissues from absorbing industrial toxins in the environment. 2. Antioxidants Kombucha contains abundant antioxidants including vitamins E, C, beta-carotene, and other carotenoids. Like black tea, kombucha also contains polyphenols and other compounds with antioxidant powers. But because it is fermented, kombucha is much more powerful than plain tea. Its antioxidant activity has been found to be 100 times higher than vitamin C and 25 times higher than vitamin E. For that reason drinking traditional kombucha may help cure chronic illnesses caused by oxidative stress. 3. Energy Kombucha sets iron free from black tea. That helps increase levels of blood hemoglobin, and improves oxygen flow to tissues. It also improves the body's absorption of other non-heme (plant-derived) iron. 4. Immunity Oxidative stress suppresses the immune system but kombucha's high levels of vitamin C support immunity. Its antioxidant power also protects against cell damage, inflammatory diseases, suppressed immunity, and tumors. 5. Gastric Illnesses Nonsteroidal anti-inflammatory drugs (NSAIDs) are toxic to the gut. They can lead to gastric ulcers. NSAID can disrupt blood circulation to the stomach's mucous membrane. Kombucha has been shown to effectively heal gastric ulceration. The researchers believe the fermented tea protects the mucin content of the stomach. Its antioxidant activity also protects the lining of the gut. Kombucha also reduces gastric acid secretion that can damage the mucous membrane. In fact, kombucha has been found as effective in healing ulcers as prescription omeprazole (brand name Prilosec). 6. Obesity Kombucha helps balance the metabolism. Animal studies show the tea may cause weight loss by encouraging calorie restriction.
