Betaine HCl - Should YOU take it?

The last blog on Betaine HCl created quite a stir so this one is to clarify my position.

The issue with Betaine HCl is NOT the HCl (stomach acid) but the Betaine part of the complex. Those who should NOT take Betaine HCl are those with more severe gut issues including"

• Reflux and related symptoms - like throat tightening

• Know pathogen burden in your gut - stool testing can elucidate this

• Bloating / SIBO (small intestine bacterial overload).

For those WITHOUT symptoms, Betaine HCl is OK to take. For example, I take Betaine HCl and will continue to take this to help with digestion. However, when my supply is exhausted, I will discontinue its use and use apple cider vinegar and vitamin C in its place per the protocol from the last blog (provided below)

Betaine HCl is widely suggested and used, and very few people experience worsening of their gut symptoms. In fact, most see improvement. My own daughter is a case in point. She has had historic gut issues and taking this acid complex improved her symptoms dramatically to the point where she told me she is living "my best life!"

A way to make sure Betaine HCl is OK for you is to do a gut pathogen eradication. I usually recommend this protocol in concert with suggesting the Betaine HCl. The specific protocol is personal to you, but this general approach applies well to most people.

1. Cook your food - including your vegetables. This reduces the number of organisms on the food.

2. Consume some fermented foods. These probiotic foods help reduce pathogen burdens.

3. Take a variety of probiotics. I suggest rotating several types. If you have worked with me, you know the protocol. Probiotics are antibiotics.

4. Do a 1-month course (1 bottle) of Biocidin. This is a natural antibiotic against gut pathogens.

5. If you have bloating or SIBO, take Atrantil. This is known to reduce the "archaebacteria" that is thought to be the major cause of bloating and SIBO.

THE BOTTOM LINE: Many of you do NOT have to discard your Betaine HCl. If you have seen improvement on this supplement, it is working for you. You can most likely safely use your existing supply.

I prefer the apple cider vinegar and vitamin C going forward because it is just the "stomach acid support" without the added betaine ingredient.

ABOUT BETAINE....

This is not a harmful substance in general. It is present in many foods, and functional/integrative practitioners will recommend Betaine and similar supplements if you have high homocysteine or you otherwise are poor at the methylation pathway. To that point, many foods contain betaine. Here are some examples.

Betaine (trimethylglycine) is primarily found in wheat products, leafy greens, root vegetables, and certain shellfish. Wheat bran and wheat germ contain the highest concentrations, while beets, spinach, quinoa, and shrimp are also excellent sources.

So you see, Betaine is NOT dangerous, but may just get in the way when we are trying to improve your gut health. There is no free lunch, and we are always looking at the risk-to-benefit considerations. If you are taking a multivitamin with the methylated forms of the "B" vitamins, you are getting some Betaine, or equivalent, at a low dose (unless your vitamin has very high levels of B vitamins).

SUMMARY: When you need to augment stomach acid, apple cider vinegar and vitamin C just supply acid, whereas Betaine HCl provides acid and the trimethylglycine. This is not a problem for most people. And, in those where it may create a problem, this is NOT deadly or severely harmful.

**** Get your gut fixed by reducing pathogen burden, as one step and then taking your remaining supply of Betaine HCl will NOT BE A PROBLEM.*****

PREVIOUS BLOG - BETAINE HCL

Betaine HCl is a widely used supplement, particularly within the integrative and functional medicine communities, though it is not supported by extensive formal clinical trials. It is commonly recommended for hypochlorhydria (low stomach acid) to improve digestion, enhance nutrient absorption (such as protein, vitamin B12, and minerals), and alleviate symptoms like bloating and indigestion.

Despite its popularity among health practitioners and consumers, the scientific evidence for its broad efficacy remains limited. While some studies confirm it can effectively re-acidify the stomach in individuals taking acid-reducing medications, many claims regarding its benefits for conditions like allergies or reflux lack rigorous controlled trial data. Consequently, its use is often guided by anecdotal reports and empirical testing protocols rather than comprehensive scientific consensus.

I recently had a client who was exposed to E. coli through a water source. I started recommending Betaine HCl (which the client was already taking based on a previous recommendation). I decided to use OpenEvidence AI to confirm that betaine HCl was effective against E. coli. I did not anticipate the answer.

I'm including the OpenEvidence discussion as a downloadable file.

This is a long but important discussion. However, based on that discussion, here is my current recommendation for supporting stomach acid in a way that:

1. helps with digestion

2. reduces gut pathogen burden.

What follows is the first couple of pages of the downloadable file titled, "Betaine HCl - New Information, New Recommendations."

Many who are taking Betaine HCl for stomach acid enhancement should reconsider this choice and move to apple cider vinegar and vitamin C instead.

Betaine hydrochloride is a salt compound where betaine (trimethylglycine) is ionically bound to a chloride counterion via a hydrochloric acid molecule. It is not covalently bonded in a way that requires chemical breakdown to separate the components; rather, it exists as a stable ionic lattice. 

When the supplement capsule reaches the stomach, it dissolves in gastric fluids, causing the salt to dissociate. This process releases free hydrogen ions and free chloride ions directly into the gastric lumen, along with free betaine. This dissociation is rapid, typically occurring within minutes, which allows the free acid to temporarily lower gastric pH and support digestion without releasing corrosive acid in the mouth or esophagus.

During a recent consultation, the person reported testing positive for E. coli. I recommended taking Betaine HCl with meals to potentially eradicate the bug. Before finalizing the suggestion, the issue of E. coli and betaine HCl was run through OpenEvidence AI. The answer was quite surprising. 

Before getting into the science of Betaine HCl, here is the modified gut-acidifying protocol that replaces it.

The following protocol is synthesized from the available pharmacokinetic and clinical data:

Apple Cider Vinegar:

• Dose: 1–2 tablespoons (15–30 mL) of raw, unfiltered ACV diluted in 200–240 mL of water [24][30]

• Timing: 10–15 minutes before meals — this provides immediate luminal acidification to prime the antimicrobial environment before food arrives

• Frequency: Before each main meal (2–3 times daily)

• Important: Always dilute — undiluted ACV (pH ~2.5–3.0) can cause esophageal mucosal injury and dental enamel erosion. Drinking through a straw and rinsing the mouth with plain water afterward further protects dental enamel. [24]

• For reflux-specific concerns: Start with 1 tablespoon in a full glass of water and titrate up. If reflux symptoms transiently worsen in the first 1–2 days, this may indicate esophageal mucosal sensitivity rather than excess acid — consider adding an alginate (see below) for the first week

Ascorbic Acid:

• Dose: 500–1,000 mg chewable tablet or powder [20][26]

• Timing: With meals — taken alongside food, the slower dissolution and sustained pH reduction covers the 60–120 minute postprandial digestive window when acid is most needed for protein digestion and pathogen killing

• Frequency: With each main meal (2–3 times daily), not exceeding 2,000 mg total daily [27]

• Form: Chewable tablets were used in the clinical study demonstrating pH reduction; capsules or powder dissolved in water are alternatives. Avoid buffered or esterified vitamin C (e.g., calcium ascorbate, sodium ascorbate) — these have higher pH and will not provide the acidification benefit [20]

• Caution: At doses >1,000 mg/day, plasma levels plateau and excess is renally excreted; doses >2,000 mg/day increase risk of osmotic diarrhea and, in susceptible individuals, oxalate kidney stones [26-27]

  
  

Combined Protocol Summary:

1. 15 minutes before meal: 1–2 tbsp ACV in 240 mL water (rapid acidification) (Note: ACV pills are an acceptable alternative to taking the liquid)

2. With meal: 500–1,000 mg chewable ascorbic acid (sustained acidification + antimicrobial + iron absorption enhancement)

3. If breakthrough reflux occurs postprandially: An alginate-based formulation (e.g., Gaviscon Advance) can be taken after meals — alginates form a physical raft that displaces the postprandial acid pocket without suppressing acid, and have been shown to be non-inferior to omeprazole for symptom relief in non-erosive reflux disease

Sodium alginate is a natural, water-soluble polysaccharide extracted from the cell walls of brown algae (seaweed). In the gastrointestinal tract, sodium alginate reacts with stomach acid to form a viscous gel barrier that floats on stomach contents, making it an effective treatment for acid reflux (GERD). It is generally recognized as safe, with potential side effects being mild and transient, such as bloating or nausea.

Previous blog on supplements.

Why are you taking supplements, and how did you end up taking too many?

I get the complaint about taking TOO MANY supplements daily!

Is there a solution? YES!

I use and suggest supplements for specific treatments based on client health complaints and lab values. There is a major difference between:

• taking supplements, and

• using supplements as part of a treatment.

  
  

IMHO, we do need a few supplements, in general, because of deficiencies in our diets. That's what supplementation is for.

HOWEVER, MORE IMPORTANTLY, high(er) doses of specific supplements or combinations are useful to treat health problems or conditions.

WHAT IS THE DIFFERENCE BETWEEN SUPPLEMENTATION AND SUPPLEMENTS AS PART OF A TREATMENT? There are 3 major differences.

1. Dose: Treatments with supplements usually involve MUCH HIGHER DOSES.

2. Duration: In some instances, the high treatment dose is done for short periods. This is referred to as "pulsing" the dose. In other cases, the duration is long-term and is based on bona fide clinical studies.

3. Combinations of supplements with consideration of dose and duration. For example, a significant study on vessel health showed that the RIGHT dose and Right duration of nattokinase significantly improved key markers of vascular health. However, nattokinase is not the only "proteolytic enzyme" that can improve vascular health. Unfortunately, good studies seldom use combination therapies because they are most always trying to isolate the effectiveness of 1 type of treatment. Augmenting the treatment with other proteolytic enzymes that are not "contraindicated" is probably a better approach than using just one type, as they may function through different mechanisms or have different "pharmacokinetics," which simply means they can distribute through your body differently.

At the bottom of this blog, I list key supplements to address common deficiencies, but first, let's cover areas where "supplements as treatments" provide MUCH MORE VALUE.

Your data - you - provide insights into treatments that may solve hidden or obvious health problems. My order, by which I suggest "treatment" is as follows.

Optimize pathways of health. I'm not giving specific recommendations because treatments will vary by individual.

1. Immunity: This is the most critical pathway as it declines substantially as we age.

2. Detox: Make sure your liver and kidneys are functioning optimally. Consider doing a detox for both organs annually.

3. Metabolic/energy: Optimize your "sugar" levels with nutrient-dense foods and healthy fats.

4. Repair: Chronic disease, simply put, is when your repair pathway is less robust compared to deterioration (wear and tear).

5. Regulatory: How are your hormone/peptide levels (insulin is a peptide!). Most people are quite low, especially with sex hormones.

Treat based on 5 simple mechanisms of disease. This concept of mechanisms simplifies supplement and treatment approaches.

1. You are what you absorb: Proper micronutrient status is critical to essentially every pathway. Thus, almost anything you do to enhance gut function is in play here. However, it is not simply about "throwing" probiotics at your system. That's why I have developed a comprehensive gut optimization program called "8R."

2. Thrive vs. Survive: Stress is a major underlying driver of chronic diseases. And, there are supplement/treatment strategies that can make your body more resilient to stress. Some stress is good - for example, exercising a muscle. But too much is harmful. Make that muscle stronger, and it can withstand more stress. This is true beyond the "muscle" analogy.

3. Stealth Infections: This concept is highly under-appreciated even in Functional Medicine. Dental infections are well understood but seldom linked to arthritis, dementia, chronic pain, chronic fatigue, and vascular disease. These are "sleeper cell" organisms, well described by the founder of the Mayo Clinic, Charles Mayo, MD, over 100 years ago. He popularized the term "focal infection," aka a highly localized, stealth infection.

4. Inflammation: This may be due to food sensitivities, diet, gut dysbiosis, heavy metals, or other non-infectious toxins. The source(s) need to be identified. Also, anti-inflammatory supplements, foods, and treatments often resolve this type of problem.

5. Lack of Autophagy: Constant eating, lack of exercise, both aerobic and weight-bearing, and lack of sunshine and exposure to nature are key reversible causal factors.

Seldom do any of these mechanisms occur in isolation from the others. However, 1 or more may be the major contributor to your distress. A systematic approach to improving all of these is your best path to symptom or disease relief.

Here are some questions to ask yourself about the supplements you are taking.

1. Who recommended the supplement(s)?

2. What are they supposed to do?

3. What was the recommended dose and duration - and why?

4. Are there good studies on the supplements related to the problem you are trying to resolve?

5. Did the person recommending them understand how they work?

6. Have you seen an OBJECTIVE improvement by taking them?

7. Have you taken them as recommended? Are you consistent?

8. Are you getting a supplement from a reliable source (and how would you know?!)

9. This one is a bit more complicated, but I tried to cover it in this blog, and that is... What mechanism(s) or pathway(s) are the supplements supposed to improve?

What supplements or supplementation (from foods) should anyone consider?

This list is based on known deficiencies in our modern diets.

1. Magnesium: either the glycinate or chloride.

2. Multivitamin/mineral - preferably without iron but with boron, selenium, and iodine.

3. Fulvic/humic liquid (liquid is "pre-digested", so absorption will be optimized.

4. Iodine and selenium for thyroid health

5. Potassium (be careful!). Foods high in potassium are: beans, squash, mushrooms, avocado, and dark leafy greens.

6. Fat-soluble nutrients with emphasis on Vitamins A and D. The best source is cod liver oil.

7. Healthy fats, in general, including castor oil, beef tallow, butter, olive oil, walnuts, and pecans as examples.

8. Probiotics: Vary based on species and sources. Going outside and getting dirty is a better option!
