How to Test Your Stomach Acid Levels at Home
One of the simplest and most cost-effective ways to determine if you have sufficient stomach acid is by using the baking soda stomach acid test. This guide will show you how to conduct this test at home. Note that this is not a diagnostic test and should be used for guidance only.
Why Stomach Acid Matters
Good digestion is vital for overall health. It's the starting point for addressing many health issues, even those seemingly unrelated, like acne or hormonal imbalances. Contrary to popular belief, most people have too little stomach acid rather than too much. Some doctors estimate that about 90% of Americans produce insufficient stomach acid.
Stomach acid (hydrochloric acid or HCl) production can be hindered by stress, processed foods, nutrient deficiencies, allergies, some medications and excessive alcohol consumption.
Symptoms of Low Stomach Acid
Low stomach acid, known as hypochlorhydria, can lead to several health problems. Without enough HCl, the body can't effectively defend against harmful microorganisms, and food isn't properly digested, which can cause symptoms such as:
Heartburn or indigestion
Bloating, cramping, or gas
Constipation or diarrhea
Food sensitivities or allergies
Dry skin, brittle hair, or nails
Chronic fatigue
Autoimmunity
Gut issues like IBS or SIBO
The Baking Soda Stomach Acid Test
The baking soda test involves a simple chemical reaction between sodium bicarbonate (baking soda) and hydrochloric acid (stomach acid), producing carbon dioxide gas and causing burping.
How to Perform the Test:
First thing in the morning, before eating or drinking, mix 1/4 teaspoon of baking soda in 4 ounces (~115 ml) of cold water.
Drink the solution.
Set a timer and observe how long it takes for you to burp. If you don't burp within five minutes, stop timing.
Burping within three minutes may indicate adequate stomach acid levels, while burping after three minutes (or not at all) may suggest low stomach acid.
Is the Test Accurate?
While this test provides insight into your stomach acid levels, it's not highly scientific. To improve accuracy, perform the test over three to five consecutive mornings.
How Does One Get Diagnosed With Low Stomach Acid
The only way to get a diagnostic for Hypochlorhydria is to undergo an Heidelberg test. A clear diagnosis of low stomach acid can only be obtained by performing this gastric pH analysis test. However, this test is rather invasive and not commonly performed. In my practice I do not require it as we can simply experiment with supplementation to see if it helps improve digestion and relieve symptoms.
How The Heidelberg Test is Done
During this test, a patient swallows a small electronic device about the size of a vitamin capsule. This device tracks acid levels in the stomach (pH measurements) over a period of time (usually 1 or 2 hours).
Increasing Stomach Acid Naturally
If you suspect low stomach acid, there are natural ways to increase it:
Apple Cider Vinegar: Use a capful of raw, unfiltered apple cider vinegar diluted in a shot glass of water.
Digestive Bitters: Take 1/4 teaspoon of bitters before meals to stimulate HCl production. You can make your own or try a trusted brand like Urban Moonshine or Canadian Bitters.
Betaine HCl: This naturally occurring amino acid compound, often derived from beets, can significantly boost stomach acid levels. However, consult a practitioner before use, especially if you have a history of ulcers, gastric inflammation, or are currently taking certain medications.
Understanding and addressing your stomach acid levels is crucial for optimal digestion and overall health. By following this simple baking soda test, you can gain valuable insights and take steps to improve your digestive health naturally. If you need personalized guidance, consider consulting with a me or any gut health practitioner of your choice.
