What is low stomach acid?
Stomach acid facilitates protein digestion and the absorption of iron, calcium and vitamin B1; and prevents bacterial overgrowth. Low levels of stomach acid (hypochlorhydria) can lead to vitamin and mineral deficiencies (e.g. vitamin B12, iron, calcium and magnesium)1, and increased risk of food allergies2 and small intestine bacterial overgrowth (SIBO)3.
How to test your stomach acid at home?
- Take one 500mg capsule of betaine HCl before a protein-containing meal (when you are most hungry and therefore when your stomach acid is highest)
- You have sufficient stomach acid if you experience a tingling, burning sensation similar to heartburn. Re-test this a few times to confirm. Any feeling of discomfort can be neutralized with one tsp baking soda with water or milk.
- If there is no tingling/burning sensation, take two capsules with each meal.
- Increase the number of capsules every two days up to a maximum of five capsules with each meal if necessary; and for a maximum of one week.
- When you experience the tingling/burning sensation, this indicates an excessive dose, and your level of HCl deficiency.
- If HCl deficiency is found, it may be useful to supplement with betaine HCl to maximize absorption of nutrients. Smaller meals may require less HCl, so the number of capsules should be reduced accordingly. Supplementation should be administered under the guidance of qualified nutritionist.
