  • Mucin
  • Intrinsic factor
  • Peptides
  • Nucleic acids and
  • Electrolytes

Furthermore, they may contain saliva from swallowing, bile from gastroduodenal reflux, inflammatory mediators, or even blood from damaged stomach walls.

The amount of gastric juice produced per day is likely to be between 3 and 4 liters. The hydrochloric acid in the gastric juice breaks down the food. At the same time, digestive enzymes break down the proteins.

Acidic gastric juice also kills bacteria. Mucus covers the stomach wall with a protective layer. This, along with bicarbonate, ensures that the stomach wall itself isn’t damaged by hydrochloric acid.

Stomach acid is highly acidic. It has to be must be highly acidic for it to break down everything from meat to tough, fibrous plants.

Acid levels in fluids are stronger at lower pH levels and weak at higher PH levels. I am sure now can guess what is the pH level of water. The pH level of water is 7 the midpoint of 0 to 14.

Stomach Acid pH Level

Here are few examples for you to understand easily:

  • Battery acid – It has a pH of 0. Battery acids are extremely potent.
  • Water – pH level of water is 7. It is a natural liquid.
  • Alkaline – Seawater, Baking soda, bleaches pH levels from 8 to 13.

A stomach acid’s pH reading is between 1-2 – Highly Acidic

A stomach acid’s pH is between 1-2. It is quite acidic. In fact, battery acid is capable of dissolving materials such as metals and bones. In the case of stomach acid, with its pH level, just one or two spots higher can be deadly. It is good enough to damage the strongest materials, like bones and teeth.

  • High-stress levels
  • Aging and mostly over 65
