What is this page for?

First and foremost: checking HCl against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.

Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of HCl by Loomis Enzymes

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 6, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 2 of its 12 active ingredients.
  • “Proprietary Enzyme Blend” is a proprietary blend — the label gives one combined amount (274 mg) without saying how much of each component you get.

This product contains 12 active ingredients, most of them digestive enzymes designed to break down different parts of food. Amylase, protease, lipase, cellulase, invertase, glucoamylase, hemicellulase, and diastase are carbohydrate- and protein-splitting enzymes, along with alpha-galactosidase (which helps with complex sugars) and fungal pepsin (another protease).

Betaine hydrochloride is added to increase stomach acid, and quinoa is included as a source nutrient. The product also lists inactive ingredients: cellulose (a binder), water, and phytase.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: pH balancing system.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence supporting these ingredients is limited. For the enzymes and betaine hydrochloride, we have insufficient reliable evidence to rate their effectiveness for the conditions they're marketed for—including indigestion (dyspepsia), inflammatory bowel disease, and various digestive complaints.

Quinoa, eaten as food, also lacks established evidence for the health claims sometimes made about it. This doesn't mean the product doesn't work; it means the data we hold hasn't established that it does.

The evidence, ingredient by ingredient Betaine Hydrochloride Quinoa Proteolytic Enzymes (proteases) Lipase

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Protease and fungal pepsin are generally well tolerated by most adults, but both can cause digestive upset or allergic reactions—and rarely, occupational exposure to airborne pepsin has triggered allergic rhinitis or asthma in case reports. Lipase appears generally well tolerated in supplement form, though people with serious digestive conditions should use it only under medical guidance.

Betaine hydrochloride may irritate your stomach and is not safe if you have ulcers, gastritis, or true acid reflux. Quinoa is widely eaten as food and is generally safe, though rare allergic reactions including anaphylaxis have been reported.

During pregnancy, safety data is limited for most ingredients here. Protease, lipase, and betaine hydrochloride should be avoided during pregnancy unless prescribed by your doctor.

Quinoa eaten as normal food is considered safe in pregnancy. During breastfeeding, protease and lipase are not recommended without medical advice, and betaine hydrochloride should be avoided.

Talk with your doctor or pharmacist before using this product if you're pregnant or breastfeeding.

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 4 matched ingredients can interact with medications — Betaine Hydrochloride.
  • The most serious interaction on file is rated Minor.
  • For scale: 36 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take acid-reducing medications: H2-blockers (like famotidine or ranitidine), antacids, or proton pump inhibitors (like omeprazole or pantoprazole). Betaine hydrochloride can interfere with how these work.

Also let your healthcare provider know if you have a history of ulcers, gastritis, or reflux disease.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

This is a multi-enzyme digestive supplement. If you take acid-reducing medications—H2-blockers, antacids, or PPIs—check your specific drugs before starting, because betaine hydrochloride may reduce how well they work.

If you have ulcers or acid reflux, avoid this product. Bring the ingredient list to your doctor or pharmacist to confirm it's right for you, especially if you're pregnant, breastfeeding, or have a sensitive stomach.

HCl by Loomis Enzymes: Common Questions

Does HCl by Loomis Enzymes interact with any medications?
Yes. Based on its ingredients, HCl has a known interaction with 36 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
HCl contains 12 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does this product have a lot of fillers?
It contains a few inactive ingredients—cellulose (a binder), water, and phytase—but nothing unusual. Most of what you're getting is the active enzymes and nutrients.
Can I take this if I'm pregnant?
Most of the enzymes in this product haven't been safety-tested in pregnancy, and betaine hydrochloride should be avoided during pregnancy unless your doctor prescribes it. Talk with your doctor before starting.
Is this safe if I have acid reflux?
No. Betaine hydrochloride increases stomach acid and can irritate your stomach lining—it's not safe for people with true acid reflux disease, gastritis, or ulcers. Skip this product and discuss alternatives with your pharmacist.
What is betaine hydrochloride doing in here?
It's added to increase stomach acidity, on the theory that stronger stomach acid helps digestion. However, the evidence that it actually improves digestion is insufficient, and it can cause problems if you take acid-reducing medications or have reflux.
Can I take this with my antacid or heartburn medication?
Not safely. Betaine hydrochloride works against acid-reducing medications—it increases acid while your medication decreases it—so they'd be working against each other. Check with your pharmacist about timing or whether a different product is better for you.
Is quinoa in this product good for weight loss or hormones?
Quinoa is a nutritious food, but we don't have reliable evidence that the amount in this supplement helps with weight loss or hormonal issues. It's included mainly as a nutrient source.
