Study Description: Research has suggested that sodium bicarbonate (the active ingredient in baking soda) can slow the rate of decline in kidney function in patients with chronic kidney disease. The way in which sodium bicarbonate works to have this positive effect is not very well understood but it is thought to be acting through the cardiovascular system (parasympathetic activity), lowering inflammation. this potential mechanism of action is yet to be confirmed or investigated in humans. Therefore, the purpose of this pilot study is to explore the mechanism of action of sodium bicarbonate ingestion through parasympathetic activity and markers of inflammation in humans.
