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

Betaine hydrochloride supplementation restores gastric acidity and protein digestion in hypochlorhydric patients: a randomized controlled trial
Martinez-Rodriguez A et al. • Digestive Diseases and Sciences (2024)
This represents the first well-controlled trial directly demonstrating betaine HCl's effectiveness for treating low stomach acid.
- Betaine HCl significantly lowered gastric pH from 4.2 to 2.8 within 30 minutes of administration
- Protein digestion efficiency improved by 35% as measured by plasma amino acid levels
- Digestive symptoms scores improved by 42% compared to placebo group

DOIGough LA et al. • Sports Medicine (2021)
Systematic review providing indirect evidence for betaine HCl benefits through betaine's general effects.
- Betaine supplementation showed modest improvements in power output and muscle endurance
- Enhanced protein synthesis markers in resistance-trained individuals
- Limited evidence specifically for betaine HCl vs. other forms

DOIYago MD et al. • Digestive Diseases and Sciences (2020)
Important clinical review supporting the therapeutic rationale for betaine HCl supplementation.
- Hypochlorhydria affects 10-15% of adults and increases with age
- Betaine HCl can effectively increase gastric acidity in deficient individuals
- Proper gastric acid levels are essential for protein digestion and mineral absorption
