Betaine hydrochloride is a chemical substance created in a laboratory with an interesting history. It's an acidic form of betaine, a vitamin-like substance present in grains and other foods. This article delves into the uses, effectiveness, side effects, and precautions associated with betaine hydrochloride.
What is Betaine?
Betaine, also known as trimethylglycine, is a derivative of the nutrient choline. It's naturally produced in the body through the metabolism of choline and can be found in foods like beets, spinach, shellfish, wheat bran, and wheat germ. Betaine is also used to treat homocystinuria (an inherited condition in which the body cannot break down a certain protein, causing build-up of homocysteine in the blood). Increased amounts of homocysteine in the body can cause symptoms such as extreme tiredness, seizures, dislocation of the lens of the eye, abnormal bone structure, osteoporosis (weak bones), blood clots, or decreased weight or rate of weight gain and slowed development in children. It works by decreasing the amount of homocysteine in the blood.
Betaine Hydrochloride vs. Betaine Anhydrous
It's crucial not to confuse betaine hydrochloride with betaine anhydrous. The FDA-approved betaine anhydrous product should be used exclusively for treating high levels of homocysteine in the urine (homocystinuria).
How Betaine Hydrochloride Works
In the stomach, betaine hydrochloride separates into betaine and hydrochloric acid. Hydrochloric acid (HCl) is naturally produced by the stomach's parietal cells and is vital for protein digestion and nutrient absorption.
Uses of Betaine Hydrochloride
Betaine hydrochloride has been used for various conditions, including:

- Abnormally low levels of potassium (hypokalemia)
- High levels of homocysteine in the blood
- Hay fever
- "Tired blood" (anemia)
- Asthma
- "Hardening of the arteries" (atherosclerosis)
- Yeast infections
- Diarrhea
- Food allergies
- Gallstones
- Inner ear infections
- Rheumatoid arthritis (RA)
- Thyroid disorders
- Improving digestion in people with low stomach acid (hypochlorhydria)
However, it is important to note that there is no good scientific evidence to support any use of betaine hydrochloride.
Effectiveness of Betaine Hydrochloride
Currently, there is insufficient reliable information to determine the effectiveness of betaine hydrochloride for any of the conditions mentioned above. The FDA banned its use in over-the-counter (OTC) medicines due to a lack of information about whether it is safe and effective.
Betaine Hydrochloride for Digestive Issues
Hypochlorhydria
Betaine hydrochloride has been historically prescribed for people with low stomach acid (hypochlorhydria). Supplementing with betaine HCl increases the amount of hydrochloric acid in the stomach, which may improve protein digestion and the absorption of nutrients like iron, calcium, magnesium, and vitamin B12. It is important to note, however, that supplementation with betaine HCl should be limited to people who have a proven deficit in stomach acid production. This condition can be diagnosed by a doctor.
Other GI Conditions
Betaine HCl may also be an effective treatment for gastrointestinal conditions like chronic indigestion and gastroesophageal reflux disease (GERD). It may also be able to offset some of the side effects caused by proton pump inhibitors (PPIs) used for acid reflux or GERD.
Candida Overgrowth
Hydrochloric-acid secretion from the stomach, pancreatic enzymes, and bile all inhibit the overgrowth of Candida and prevent its penetration into the absorptive surfaces of the small intestine. Decreased secretion of any of these important digestive components can lead to overgrowth of Candida in the gastrointestinal tract.

Betaine Hydrochloride and Allergies
According to one theory, allergies are triggered by partially undigested protein. Proteolytic enzymes may reduce allergy symptoms by further breaking down undigested protein to sizes that are too small to cause allergic reactions. Preliminary human evidence supports this theory. Hydrochloric acid secreted by the stomach also helps the digestion of protein, and preliminary research suggests that some people with allergies may not produce adequate amounts of stomach acid.
Betaine Hydrochloride and Cardiovascular Health
Betaine is best known for helping reduce plasma homocysteine levels, which is directly related to lowering the risk for heart disease. Some researchers think this may mean that betaine supplementation can lower your risk of cardiovascular diseases (CVD), but the research isn’t quite there yet. However, it’s important to note that some studies have found that betaine supplements have a negative effect on blood lipid levels.
Betaine Hydrochloride and Body Composition
Currently, one of the most popular uses of OTC supplementation with betaine HCl is to improve body composition and overall exercise performance. Some experts say it helps, and others say there’s not enough evidence to support its use. Some studies looking at the effects of betaine supplementation on both male and female athletes found that it helped reduce body fat after a six- or eight-week period. Still, no difference in muscle strength was reported in either study. While a 2019 study suggests that betaine may reduce body fat mass and percentage, a 2017 study found no evidence that betaine supplementation could improve muscle strength or performance.
Betaine Hydrochloride and Liver Health
Animal studies have found that betaine can prevent fatty deposits from accumulating in the liver and possibly reverse fatty liver disease. Fat deposits in the liver can occur from alcohol overuse, obesity, and other health conditions. They can cause inflammation, liver damage, and even liver failure. Betaine is used to treat alcoholic liver damage that results in the accumulation of fat in the liver.
Betaine Hydrochloride and Skin Health
Betaine can also keep skin moisturized by acting as a natural hydrator due to the way it keeps moisture locked into the skin.

Dosage and Administration of Betaine
Betaine comes as a powder to be mixed with food or drink and taken by mouth. It is usually taken twice a day. Take betaine at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take betaine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Your doctor will probably start you on a low dose of betaine and gradually increase your dose based on your body's response to the medication.
For oral dosage form (powder for solution):
- To prevent buildup of homocysteine:
- Adults, teenagers, and children 3 years of age and older-The starting dose is usually 3 grams taken two times a day with meals. Your doctor may adjust your dose as needed.
- Children younger than 3 years of age-The dose is based on body weight and must be determined by your doctor. Betaine should be taken with meals.
Supplementing betaine hydrochloride with meals may improve digestion in people who have been diagnosed with low stomach acid (hypochlorhydria). The amount of betaine HCl used varies with the size of the meal and with the amount of protein ingested. Typical amounts recommended by doctors range from 600 to 2,400 mg per meal.
It is important to note that the appropriate dose of betaine hydrochloride depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for betaine hydrochloride. Keep in mind that natural products are not always necessarily safe and dosages can be important.
Side Effects of Betaine Hydrochloride
Betaine hydrochloride is POSSIBLY SAFE when taken as a single dose. There isn't enough information to know if betaine hydrochloride is safe when taken in multiple doses. Common side effects of betaine HCl include gastrointestinal discomfort in the form of nausea, upset stomach, heartburn, and burning sensation.
Some side effects can be serious:
- confusion
- drowsiness
- behavior changes
- headache
- vomiting
- seizures
- loss of consciousness
Large amounts of betaine HCl can burn the lining of the stomach. If a burning sensation is experienced, betaine HCl should be immediately discontinued.
Precautions and Warnings
- Pregnancy and breast-feeding: Not enough is known about the use of betaine hydrochloride during pregnancy and breast-feeding. Stay on the safe side and avoid use.
- Peptic ulcer disease: Betaine hydrochloride can increase stomach acid. There is a concern that the hydrochloric acid produced from betaine hydrochloride might irritate stomach ulcers or keep them from healing.
- All people with a history of peptic ulcers, gastritis, or gastrointestinal symptoms-particularly heartburn-should see a doctor before taking betaine HCl.
- People should not take more than 10 grains (650 mg) of betaine HCl without the recommendation of a physician.

Be cautious with this combination. Talk with your health provider.
Drug-Nutrient Interactions
Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table.
Betaine Deficiency
A betaine deficiency is not thought to be common in Western nations, mostly because dietary intake is adequate. The biggest threat to consuming low betaine levels is experiencing symptoms related to high homocysteine in the blood.
Food Sources of Betaine
According to reports, wheat bran/wheat germ is the single highest source of naturally occurring betaine. Alcoholic beverages, such as wine and beer, also contain low to moderate levels, so their high consumption rates make them another key contributor in the American diet.
Conclusion
Betaine hydrochloride is a substance with potential benefits and risks. While it has been used for various conditions, scientific evidence supporting its effectiveness is limited. It's crucial to consult with a healthcare professional before using betaine hydrochloride, especially if you have any underlying health conditions or are taking medications. They can help you determine if it's appropriate for you and monitor you for any potential side effects.
