A daily dose of sodium bicarbonate (baking soda), already used for baking, cleaning, acid indigestion, sunburn, and more — slows the decline of kidney function in some patients with advanced chronic kidney disease (CKD), reports an upcoming study in the Journal of the American Society of Nephrology (JASN).
Slows decline of kidney function
The study included 134 patients with advanced CKD and low bicarbonate levels, also called metabolic acidosis. One group received a small daily dose of sodium bicarbonate in tablet form in addition to their usual care. For this group, the rate of decline in kidney function was greatly reduced — about two-thirds slower than in patients. "In fact, in patients taking sodium bicarbonate, the rate of decline in kidney function was similar to the normal age-related decline," says Yaqoob.
