Oyster mushroom (Pleurotus ostreatus) helped bacteria grow compounds that dropped blood sugar from over 300 to 129.6 in 28 days, matching prescription diabetes drugs in rats, while also protecting the liver and cutting dangerous cell damage by half. The extract contained high levels of antioxidants (68.42 mg/g phenolics and 41.76 mg/g flavonoids) with 81% free radical fighting power, delivering both blood sugar control and cellular protection. The compounds work by targeting the enzyme that breaks down carbs, validating this mushroom-bacteria partnership as a natural food strategy for managing blood sugar and liver health.
