Assessing and Improving Stomach Acid Levels for Digestive Health
TL;DR
- Low stomach acid impairs protein digestion and mineral absorption, leading to nutrient deficiencies, gut infections, and systemic inflammation that affects energy and immune function.
- Insufficient stomach acid can cause food to ferment, producing gas that increases esophageal pressure and leads to acid reflux, while also hindering bile release and causing constipation.
- The baking soda test measures stomach acid by timing burp production after ingestion; a burp within three minutes indicates sufficient acid, while longer delays suggest deficiency.
- Betaine HCl supplements can be used to determine optimal stomach acid levels by gradually increasing dosage until digestive symptoms improve, then reducing it to find the maintenance level.
- Activating the vagus nerve through deep breathing, smelling food, or eating in a relaxed state enhances stomach acid production, crucial for effective digestion and nutrient uptake.
- The steak test evaluates stomach acid by observing post-meal symptoms like energy levels, burping, or bloating, with positive outcomes indicating adequate acid production.
- Apple cider vinegar can be used to assess mild stomach acid deficiency, where improved symptoms after consumption suggest a need for mild support, but pain indicates potential ulcers.
Deep Dive
Low stomach acid is a significant, often overlooked, contributor to digestive distress, nutrient deficiencies, and gut infections. Understanding and addressing stomach acid levels at home is crucial because insufficient acid impairs protein digestion, mineral absorption, and the natural regulation of gut bacteria, leading to symptoms like gas, bloating, reflux, and fatigue.
The primary consequence of low stomach acid is poor digestion, which cascades into multiple health issues. Without adequate hydrochloric acid (HCl), the stomach cannot effectively break down proteins into absorbable amino acids, nor can it kill pathogens ingested with food. This microbial imbalance can lead to conditions like SIBO (Small Intestinal Bacterial Overgrowth) and parasitic infections, contributing to chronic inflammation, leaky gut syndrome, and even autoimmune responses. Furthermore, stomach acid is essential for absorbing critical minerals such as magnesium, zinc, and iron, and for activating intrinsic factor, which is necessary for vitamin B12 absorption. Deficiencies in these nutrients directly impact energy levels, immune function, and overall cellular health. Low stomach acid also disrupts the digestive signaling pathway; it fails to properly close the esophageal sphincter, leading to acid reflux, and does not trigger the necessary release of bile and pancreatic enzymes in the small intestine, further exacerbating dysbiosis and nutrient malabsorption.
Fortunately, individuals can assess their stomach acid levels through simple at-home tests. The "steak test" involves consuming a well-done six-ounce steak and monitoring for symptoms like burping, bloating, gas, pain, or fatigue within two to three hours; a positive reaction suggests low acid. The apple cider vinegar test, where one tablespoon diluted in four ounces of water is consumed before a meal, can indicate mild deficiency if it improves symptoms, but pain suggests potential ulcers. The baking soda test involves drinking a mixture of baking soda and water and timing the resulting burp; a burp within three minutes indicates sufficient acid, while longer waits suggest a deficiency. If these tests reveal low stomach acid, supplemental Betaine HCl can be used to determine the optimal dosage needed for digestive support, gradually reducing the dose as the body's natural production improves over time. These interventions, alongside lifestyle strategies like mindful eating, deep breathing, and vagal nerve stimulation, can restore proper digestive function and nutrient absorption, thereby enhancing overall health and well-being.
Action Items
- Audit stomach acid production: Perform baking soda test first thing in morning to establish baseline burp time within 3 minutes.
- Evaluate steak digestion: Consume 6oz well-done steak and monitor for 2-3 hours for energy, gas, or bloating.
- Test apple cider vinegar efficacy: Drink 1 tbsp diluted ACV with 4oz water, then repeat steak test to gauge symptom improvement.
- Determine Betaine HCl dosage: If steak test is poor, take 1 capsule Betaine HCl with a meal and adjust dosage until symptoms resolve.

"Low stomach acid is one of the biggest hidden drivers behind gas, bloating, and microbial overgrowth."
Dr. Jockers identifies low stomach acid as a primary cause for common digestive issues. This statement highlights the critical role stomach acid plays in preventing gas, bloating, and the proliferation of microbes in the gut.
"stomach acid's job number one is to sterilize the food that's coming in anything we eat even if it was just cooked has potential pathogens bacteria and different microbes that are on it and we don't want those microbes getting deep into our system or at least we want to help balance or regulate them the microbes we want to reduce the overall microbial load that's coming into our system stomach acid does that it helps kill off bacteria and different microbes that are not able to live in a low in a very strong acid environment so that's really important if not we're at a higher risk for uh food borne illness for developing bacterial and microbial overgrowths in our gut developing leaky gut syndrome gut inflammation autoimmunity and the like"
Dr. Jockers explains that stomach acid acts as a primary defense mechanism by sterilizing ingested food. This process is crucial for preventing pathogens from entering the system, thereby reducing the risk of foodborne illnesses, gut overgrowths, leaky gut, and inflammation.
"also stomach acid is key for the absorption of key minerals it helps to chelate magnesium and calcium and zinc and iron and all of these key minerals that come in our system if we have low stomach acid or hypochlorhydria we're not going to be able to absorb those effectively"
Dr. Jockers emphasizes the role of stomach acid in mineral absorption, specifically mentioning magnesium, calcium, zinc, and iron. He explains that insufficient stomach acid, or hypochlorhydria, directly impairs the body's ability to effectively absorb these essential minerals.
"good stomach acid helps close the esophageal sphincter and open up the pyloric sphincter so when we don't produce enough stomach acid food just sits in our stomach and as it sits there it starts to ferment and rot and produce gas and that gas will put pressure on the esophageal sphincter and if there's enough pressure that opens up that sphincter and now we end up with acid jumping up into our esophagus causing acid reflux gastroesophageal reflux disease causing more burping and belching coming out of that area"
Dr. Jockers details how adequate stomach acid regulates the digestive sphincters, preventing reflux. He explains that when stomach acid is low, food ferments in the stomach, producing gas that can force open the esophageal sphincter, leading to acid reflux and related symptoms.
"the baking soda is sodium bicarbonate the sodium bicarbonate will meet with the hydrochloric acid so it's a base and an acid and when the base and the acid mix it should produce carbon dioxide as a byproduct and so when people do this you consume that you should really burp in about roughly three minutes within three minutes ideally within a minute after you drink this and you do this first thing in the morning"
Dr. Jockers describes the baking soda test as a method to assess stomach acid levels. He explains that the reaction between baking soda (a base) and hydrochloric acid in the stomach produces carbon dioxide, which should result in a burp within approximately three minutes.
"you get a supplement called betaine hcl okay and you can get this with enzymes if you want you know there's a lot of different types of betaine hcl you just get it alone stand alone or you can get it with bile with um digestive enzymes ideally just you know for the test you can just get it alone betaine hcl and what you do is you repeat the steak test you take one capsule of the betaine hcl with the meal okay so right in the beginning or right in the middle somewhere in that that frame don't take it at the end and then see how you feel over the next few hours if you notice that your symptoms have improved that's a good sign"
Dr. Jockers introduces betaine HCl as a supplement to aid digestion and suggests a method for determining the correct dosage. He advises taking one capsule with a meal and observing symptom improvement, indicating that this supplement can help if stomach acid is insufficient.
