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.

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.
Take with food
| Form | Type |
|---|---|
| 💊Capsules (often combined with pepsin) | Recommended |
| 💊Tablets | Alternative |
Combining with pepsin enhances protein digestion. Capsules allow easy dose adjustment.
Minimum: 0 days
Optimal: 0 days
Cycling: Not required
Note: MUST be taken with food containing protein. Never on empty stomach. Take at start of meal.
Improved protein digestion and comfort
Less post-meal bloating and gas
Consult doctor
Often beneficial due to age-related acid decline
Counteracts their effect — usually one or the other
May increase ulcer risk
Tip: Sign of adequate dose — reduce by 1 capsule
Tip: May indicate you don't need it or dose too high

“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.”
