The stomach produces acid to break down food, but too much or too little can lead to digestive problems like bloating, acid reflux, or indigestion. Bicarbonates act as natural regulators, keeping the acid at the right level. When acidity rises too high, bicarbonates neutralize it, preventing discomfort. If acidity is too low, they help stimulate proper digestion. This balance ensures that food is broken down efficiently and nutrients are absorbed properly without unnecessary strain on the stomach.
