In this study, we describe the changes associated with the consumption of an extremely biodiverse probiotic yogurt in a 55-year-old female from South Vietnam. In August 2019, the subject voluntarily embarked on a three-month nutritional experience and decided to share her experience with the goal of advancing scientific knowledge in the field of nutritional health. Consumption of this biodiverse probiotic yogurt was associated with a decrease in serum alpha-N-acetylgalactosaminidase (nagalase) activity, increased elimination of toxic metals and non-metal toxicants, a trend toward normalization of the lipid profile, and a trend toward a rebalance of the gut microbiota.
