Baking Soda for Kidney Health

Research suggests that sodium bicarbonate, commonly known as baking soda, has been explored in at least one small randomized trial in the context of nasal irrigation rather than direct kidney health applications, and the available linked evidence does not address kidney health outcomes. The single study identified enrolled 79 adults with COVID-19 and examined nasal rinsing with a sodium bicarbonate solution, finding lower hospitalization and death rates compared to a national dataset, though the study's small size, lack of blinding, and use of a population-level comparison rather than a true control group substantially limit the conclusions that can be drawn. It is worth noting that while baking soda has been studied separately in the scientific literature for its potential role in slowing chronic kidney disease progression through its alkalizing properties, none of the provided studies address this topic. Readers interested in sodium bicarbonate and kidney health specifically should seek out research focused directly on that question, as the evidence summarized here does not support conclusions in that area.
