Low Stomach Acid
Description
This page has 14 references
"Low Stomach Acid" is a condition where the stomach doesn’t produce enough hydrochloric acid to support digestion. This leads to symptoms like bloating, indigestion, nutrient deficiencies, and increased risk of infections or microbial overgrowth. Common causes include aging, stress, low mineral intake, and overuse of acid-suppressing medications. Restoring stomach acid involves mindful eating, slowing down meals, increasing zinc and chloride intake, and reducing processed foods. Optimizing acid levels helps maximize absorption and guard against chronic gut imbalances.

Things To Do
To support proper stomach acid secretion and strengthen the defense systems against H. pylori, it is essential to:
consume a whole-foods-based diet consisting of fresh vegetables, fruits, lean meat, fish, legumes, whole grains, and healthy fats.
A high intake of vegetables and fruit can stimulate the defense systems against the Helicobacter infection. Vegetables and fruit contain antioxidants, such as vitamins C and E, polyphenols, and flavonoids, that strengthen the stomach acid, preventing bacteria from colonizing.
Make sure to wash your vegetables and fruits thoroughly.
To reduce the risk of contamination, cook your vegetables for at least 15 minutes before eating them.
Incorporate fermented foods, such as sauerkraut, kimchi, miso, kombucha, etc. They strengthen your gut microbiome and protect you from infection.
consume zinc-rich whole foods, such as fish, shellfish, whole grains, eggs, dairy, etc. Zinc aids in the production of stomach acid.
Eat whole foods containing B vitamins. They also aid in the production of stomach acid.
Eat slowly, and chew your food well.
stay hydrated. Drink fluids between meals, not just prior to, during, or straight after.
Furthermore, do the following:
reduce stress with mediation, mindfulness, or yoga practice. Stress has a negative impact on our gastrointestinal track.
Drink botteled water when traveling to a region where H. plyori infections are common.
low- to moderate-intensity, regular exercise.
In acid reflux, sleep on your left side.
maintain a healthy weight.
Things To Avoid
For hypochlorhydria, avoid the following:
processed, junk, and fast foods. They make digestion difficult and can contribute to acid reflux.
deep-fried, grilled, or greasy foods.
spicy foods.
eating undercooked or raw meat.
uncooked and unwashed oysters, clams, mussels, and other shellfish They can be contaminated with harmful bacteria.
contaminated water and drinking with meals.
foods you are allergic to or intolerant of.
a diet high in refined carbohydrates, sugar, and processed foods.
Too small an intake of protein and a high-carb diet can also reduce stomach acid levels.
alcohol, caffeine, soft drinks, and carbonated drinks. They can make the symptoms worse.
eating large meals, eating too close to bedtime, and eating in a hurry.
unsanitary conditions of food preparation.
irregular meal times.
eating out too often.
dehydration.
Furthermore, avoid the following:
smoking and binge drinking.
medications and antacids.
weight gain and a sedentary lifestyle.
chronic stress.
Supplements
Direct Support
(Most Helpful → Least Helpful)
These supplements directly affect low stomach acid by stimulating gastric acid production, improving protein digestion, or restoring proper pH levels in the stomach.
Betaine HCL: Betaine HCL, a source of hydrochloric acid (HCL), supports stomach acid production, essential for breaking down food, absorbing nutrients, and controlling harmful bacteria. It aids enzymatic protein digestion, improving overall digestive health in those with low stomach acid.
Indirect Support
(Most Helpful → Least Helpful)
These supplements do not target stomach acid directly but may support nutrient absorption, reduce inflammation, or enhance digestive enzyme activity.
Digestive Enzymes: Digestive enzyme supplements provide enzymes like proteases, lipases, and amylases to break down proteins, fats, and carbohydrates. While they don’t directly increase stomach acid, they enhance digestion efficiency, helping individuals with low stomach acid absorb nutrients more effectively.
Natural Compounds
These natural compounds may help manage low stomach acid by aiding digestion, promoting healthy gastric secretions, or improving nutrient breakdown.
Apple Cider Vinegar: Apple cider vinegar, with its acidic pH (2-4), helps raise stomach acidity, improving food breakdown and nutrient absorption. It’s particularly beneficial for individuals with low stomach acid, aiding digestion and enhancing enzyme activity.
Coffee: Coffee stimulates gastric acid production through its caffeine content, increasing hydrochloric acid (HCl) levels. It also enhances pepsin release, aiding protein digestion and improving digestive function in individuals with low stomach acid.
Plant Extracts
Direct Support
(Most Helpful → Least Helpful)
These plant extracts directly support stomach acid production by promoting digestive secretions, enhancing appetite, or stimulating gastric glands.
Digestive Bitters: Digestive bitters, such as gentian, dandelion root, and artichoke leaf, stimulate stomach acid and digestive enzyme production by activating taste receptors on the tongue. This enhances digestion and supports nutrient breakdown, particularly in individuals with low stomach acid.
Lemon Juice: Lemon and lime juice, with their low pH around 2, can support digestive processes by adding acidity that may aid in food breakdown and nutrient absorption. Despite their initial acidity, these citrus juices have an alkalizing effect on the body after metabolism, which supports overall digestive health.
Indirect Support
(Most Helpful → Least Helpful)
These extracts do not act directly on stomach acid levels but may support gut lining health, reduce bloating, or improve bile and enzyme flow.

Alternative Treatments
These alternative therapies support digestive activation, promote healthy stomach function, and improve nutrient assimilation in individuals with low stomach acid.
No replicated and convincing research studies are available, and there is no anecdotal evidence supporting the effectiveness of this method.

How Key Nutrients Support the Body
Enzymes and Coenzymes: Enzymes catalyze biochemical reactions, while coenzymes assist in these processes by binding temporarily to enzymes. Together, they regulate digestion, energy production, immune responses, and various metabolic pathways.
Fruit Extracts: Rich in antioxidants, vitamins, and fiber, fruit extracts offer numerous health benefits, including anti-inflammatory, anti-cancer, and immune-boosting properties. They also support digestive health and contribute to overall well-being.
Herbal Extracts: Herbal extracts contain bioactive compounds with various medicinal properties, including antioxidant, anti-inflammatory, and antimicrobial effects. They have been used traditionally to support digestion, immunity, and overall health.
Other Nutrients: Other nutrients encompass a wide array of essential compounds crucial for various physiological functions. This category includes neurotransmitters and their precursors, which facilitate nerve signaling and are vital for central nervous system function. Additionally, naturally occurring structural components and biological detergents, such as phospholipids and bile salts, play critical roles in tissue repair, fat digestion, and overall bodily function. Phospholipids contribute to cell membrane integrity and fat emulsification, while bile salts are key to digesting and absorbing dietary fats. Hormones and their precursors regulate numerous physiological processes, including metabolism, growth, and reproduction. Furthermore, naturally occurring chemicals and metals play pivotal roles in enzymatic reactions, immune function, and overall health maintenance.
