A normal stomach acid level creates a pH of 1.5 to 2.5. But as we age, the parietal cells in the stomach lining produce less Hydrochloric Acid (HCl). In fact, half of people over the age of 60 have hypochlorhydria (low stomach acid), and by age 85, 80% of relatively healthy people have low stomach acid.

Additionally, certain medications will lower stomach acid. Acid-blocking medications increases stomach pH to 3.5 or higher. This inhibits pepsin, which is essential for the digestion of protein.

Stomach acid is also necessary for absorption of many minerals. In addition, stomach acid provides our first defense against food poisoning, H. pylori, parasites, and other infections. Without adequate acid, we leave ourselves open to decreased immune resistance and a variety of other health problems.

Overgrowth of bacteria in the small intestine occurs in 20% of people aged 60 – 80 and in 40% of people over age 80.

Adequate HCI is necessary for the absorption of vitamin B12 from food; B12 deficiency causes weakness, fatigue, and nervous system problems. Vitamin C levels are also low in people with poor stomach acid. Several minerals require an acidic environment for absorption, including iron, calcium, magnesium, zinc, and copper. Acid is critical for the breakdown of protein bonds in the stomach, and poor acid content in the stomach causes indigestion. The symptoms of hypoacidity often mimic those of hyperacidity.

Hypochlorhydria may be caused by the following: Pernicious anemia, chronic Helicobacter pylori infection, long-term treatment with proton pump inhibitors (like Nexium), autoimmune gastritis, or simple nutritional deficiencies such as zinc.

COMMON SYMPTOMS OF HYPOCHLORHYDRIA

  • Chronic intestinal parasites or
    abnormal flora
  • Undigested food in stool

SELF-TESTING AND TREATMENT FOR LOW HCL (hypochlorhydria)

1. Begin by taking one 350-750 mg capsule of betaine HCl with a protein-containing meal. A normal response in a healthy person would be discomfort—basically heartburn. If you do not feel a burning sensation, begin taking two capsules with each protein-containing meal.

2. If there are no reactions after 2 days, increase the number of capsules with each meal to three.

3. Continue increasing the number of capsules every 2 days, using up to five capsules (or as your healthcare professional suggests) with each meal if necessary.

  • These dosages may seem large, but a normal functioning stomach manufactures considerably more.
  • You’ll know you’ve taken too much if you experience tingling, heartburn, diarrhea, or any type of discomfort including a feeling of unease, digestive discomfort, neck ache, backache, headache, or any
    new odd symptom.
  • If you experience tingling, burning, or any symptom that is uncomfortable, you can neutralize the acid with 1 tsp baking soda in water or milk.

4. When you reach a state of tingling, burning, or any other type of discomfort, cut back by one capsule per meal. If the discomfort continues, discontinue the HCl and consult with your healthcare professional.

5. Once you have established a dose (up to 5 capsules) that causes no symptoms, continue until your next appointment.

6. With smaller meals, you may require less HCl so you may reduce the amount of capsules taken.

Individuals with a mild HCl deficiency may regain some normal HCL secretion and thus may over time have some symptoms of heartburn from taking the HCL. Simply decrease the number of capsules you are taking until the symptoms disappear. Individuals with moderate to severely low HCl/pepsin typically do not experience such
quick improvement, so to maximize the absorption and benefits of the nutrients you take, it is important to be consistent with your HCl supplementation.

Precaution: Administration of HCl/pepsin is contraindicated in peptic ulcer disease. HCl can irritate sensitive tissue and can be corrosive to teeth; therefore, capsules should not be emptied into food or dissolved in beverages. Always follow up with your health care provider if you have any questions.
