Betaine HCl
Betaine Hydrochloride
Supplemental stomach acid for those with low acid production, supporting protein digestion and nutrient absorption.
Betaine HCl provides supplemental hydrochloric acid for people who don't produce enough stomach acid (hypochlorhydria). Low stomach acid is common with aging, PPI use, and certain conditions, leading to poor protein digestion and nutrient malabsorption. Betaine HCl restores optimal stomach pH for digestion.
Mechanisms of Action
Acid Restoration
Restores stomach pH for digestion
Nutrient Absorption
Improves mineral and B12 absorption
Recommended Dose
325-650mg with protein meals (titrate to find optimal dose)
Loading: Start with 325mg with meals. Increase by one capsule per meal until feeling warmth, then reduce by one.
Optimal Timing
- During or immediately after first few bites of protein-containing meal
Take with food
Best Form
Capsules (often combined with pepsin)
Alternatives: Tablets
Combining with pepsin enhances protein digestion. Capsules allow easy dose adjustment.
Duration
Minimum: as needed
Optimal: as needed
Cycling: Not required
Note: MUST be taken with food containing protein. Never on empty stomach. Take at start of meal.

Better Digestion
Improved protein digestion and comfort
Reduced Bloating
Less post-meal bloating and gas
Consult doctor
Often beneficial due to age-related acid decline
Who Should NOT Take This
- Active ulcers or gastritis
- H. pylori infection
- Taking NSAIDs or corticosteroids
Drug Interactions
Counteracts their effect — usually one or the other
May increase ulcer risk
Possible Side Effects
Tip: Sign of adequate dose — reduce by 1 capsule
Tip: May indicate you don't need it or dose too high
Warnings
- NEVER take on empty stomach
- Do NOT use if you have ulcers or gastritis
- Warmth in stomach = adequate dose reached
- If heartburn worsens, you may have excess acid, not low acid

Key Findings:
- The cytotoxicity of core/shells done on L929 and HeLa cell lines using 3-(4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide and trypan blue dye exclusion assays showed >89% and >80% cell viability for 24 and 48h respectively.
- About 95% cell death was occurred in 90min after hyperthermia treatment.
- The mechanism of cell death was found to be elevated ROS generation in cells after exposure to core/shells in external magnetic field.
- This study showed that these core/shells have a great potential to be used in in vivo MFH.Copyright © 2015 Elsevier B.V.

“The success with BHClP for this patient case suggests that more research is needed to fully realize the mechanisms and clinical usage.”
Key Findings:
- After a few months, the patient discontinued BHClP, and GI symptoms and dumping syndrome returned, leading to a loss of 7.5% of his body weight.
- The patient reinitiated the supplement and GI symptoms dissipated, and weight was restored.
- BHClP provided metabolic therapeutic benefit to optimize the patient's oral intake, preventing further complications and malnutrition.
- The success with BHClP for this patient case suggests that more research is needed to fully realize the mechanisms and clinical usage.

“The co-administration of rabeprazole with atazanavir resulted in significant decreases in atazanavir exposure.”
Key Findings:
- Pretreatment with rabeprazole resulted in significant reductions in atazanavir Cmax (p < 0.01) and AUC0-last (p < 0.001) (71 and 70%, respectively), and modest decreases in ritonavir Cmax and AUClast (p < 0.01) (40% and 41%, respectively).
- The addition of betaine HCl restored 13% of ATV Cmax and 12% of AUClast lost due to rabeprazole.
- The co-administration of rabeprazole with atazanavir resulted in significant decreases in atazanavir exposure.
- The addition of betaine HCl did not sufficiently mitigate the loss of ATV exposure observed during RAB-induced hypochlorhydria.

“Therefore, BHCl reversed the impact of hypochlorhydria on dasatinib drug exposure and may be an effective strategy to mitigate potential drug-drug interactions for drugs that exhibit pH-dependent solubility and are administered orally under hypochlorhydric conditions.”
Key Findings:
- Rabeprazole (20 mg b.i.d.) significantly reduced dasatinib Cmax and AUC0-∞ by 92 and 78%, respectively.
- However, coadministration of BHCl significantly increased dasatinib Cmax and AUC0-∞ by 15- and 6.7-fold, restoring them to 105 and 121%, respectively, of the control (dasatinib alone).
- In this randomized, single-dose, three-way crossover study, healthy volunteers received dasatinib (100 mg) alone, after pretreatment with rabeprazole, and with 1500 mg BHCl after rabeprazole pretreatment, to determine if BHCl can enhance dasatinib absorption in hypochlorhydric conditions.
- Therefore, BHCl reversed the impact of hypochlorhydria on dasatinib drug exposure and may be an effective strategy to mitigate potential drug-drug interactions for drugs that exhibit pH-dependent solubility and are administered orally under hypochlorhydric conditions.

“The rapid onset and relatively short duration of gastric pH reduction gives betaine HCl the potential to aid the absorption of orally administered weakly basic drugs that exhibit pH-dependent solubility when administered under hypochlorhydric conditions.”
Key Findings:
- The reacidification period was temporary with a gastric pH < 3 and < 4 lasting 73 (± 33) and 77 (± 30) min, respectively.
- Betaine HCl was well tolerated by all subjects.
- In healthy volunteers with pharmacologically induced hypochlorhydria, betaine HCl was effective at temporarily lowering gastric pH.
- The rapid onset and relatively short duration of gastric pH reduction gives betaine HCl the potential to aid the absorption of orally administered weakly basic drugs that exhibit pH-dependent solubility when administered under hypochlorhydric conditions.
