Betaine HCl with Pepsin

Description

Betaine HCl with pepsin in a single capsule, with the betaine hydrochloride weight in milligrams and the pepsin given in activity units rather than in milligrams. Betaine hcl is trimethylglycine paired with hydrochloric acid, and the acid half is the reason anyone buys it. Pepsin is a protease that only works in an acid environment, which is why the two are sold together. The label says to start at one capsule with a meal containing protein.

What is in the capsule

Why pepsin is measured in units and betaine hcl in milligrams

An enzyme is sold for what it does, not for what it weighs. Two pepsin preparations of identical mass can differ several fold in proteolytic activity, depending on how the material was graded and handled, so a milligram figure on an enzyme label carries almost no information. Activity units are the measure a laboratory can reproduce.

Betaine hydrochloride is a defined compound, so milligrams are meaningful for that half. Printing one in units and the other in milligrams looks inconsistent on a panel and is the only honest way to do it. The same rule applies across the gut health page, where protease, amylase and lipase all appear in their own activity units.

Betaine hcl and betaine anhydrous are different products

They share a molecule and nothing else. Betaine anhydrous is the neutral compound, sold in 2.5 gram servings as a training powder, and it appears on the performance page. The hydrochloride is sold in a few hundred milligrams per capsule and bought for the chloride. Shelving them together causes genuine confusion, so we keep them apart.

What the published work consists of

The human literature here is small. Most of it consists of pharmacological studies measuring intragastric pH after a betaine hydrochloride dose, including work in people whose stomach acid had been suppressed by medication, where the measured endpoint was how quickly pH fell and for how long. There are few outcome trials and no established dose.

That is a description of the evidence base rather than a claim about this bottle, and we would rather print the thin version than imply a research record that does not exist. Our note on what starting low actually means is the general version of the one capsule instruction.

How a betaine hcl capsule is usually titrated

The convention described in clinical nutrition writing is to begin with one capsule taken partway through a meal containing protein, hold there for several days, and only then consider a second. The stopping signal is warmth or burning rather than a target number of capsules. A betaine hcl label that recommends a fixed four with every meal has skipped the only step in the process that matters, and the bottle will empty faster for no stated reason.

Who should not take this

Anyone with a gastric or duodenal ulcer, anyone on a proton pump inhibitor or H2 blocker, and anyone taking non steroidal anti inflammatory drugs regularly. Adding acid to a stomach that is already irritated is a bad idea, and the fact that this is sold as a food does not change that. A pharmacist is the right person to ask.

Burning, and what it means

A warm or burning sensation after a capsule is the commonly reported effect and it tracks with dose. The convention in the clinical nutrition literature is to stop at the amount that produces it rather than push through, which is the opposite of how most supplements are discussed. Nobody prints that on a bottle, so it is printed here.

Testing

Every lot of betaine hcl with pepsin is assayed by an independent laboratory for both actives, with the enzyme activity measured rather than estimated, alongside heavy metals and microbial screening. Lots below their stated figures are withdrawn and the failing certificate stays published.
