Yes, stomach acid (aka hydrochloric acid) is acidic. However, it is secreted only when food is ingested and, hence, our stomach does not produce this acid all the time.
Each time the stomach acid (at pH 2.0) is produced, the pancreas secretes bicarbonate alkaline substance to neutralize the stomach acid so that pancreatic enzymes can work properly. Normally, after eating, there are transient changes in the blood pH, known as the acid and alkaline tides, that correspond to the stomach and pancreatic secretions. Usually the pH of the blood quickly returns to normal. However, more and more people are suffering from digestive problems where digestive secretions are out of balance due to the insufficient secretion of pancreatic bicarbonates, which is a major cause of over-acidity in the body.
Hence, many of our customers have noted that drinking alkaline water does help in digestion and those who suffer from digestive problems have seen a remarkable improvement in their condition too. Finally, drink at the recommended level of pH between 8.5~9 whether during or outside meal times.
