The pH scale in aqueous solution varies between 1 and 14:
-pH below 7: acidic solution
-pH greater than 7: basic solution
In the body, the pH varies according to the place considered. The pH of the stomach is acidic, to aid digestion, and it gradually increases in the intestine.
Some compounds have the property of stabilizing/buffering the pH: buffer solutions.
In case of too high acidity (too acidic pH), alkalizing minerals can help rebalance the pH.
Zinc contributes to normal acid-base metabolism.
Calcium contributes to the normal functioning of digestive enzymes .
