HelloPharmacist Scorecard of Zypan by SP Standard Process

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

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 0 of its 8 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (700 mg) without saying how much of each component you get.

Zypan contains 8 ingredients total, including pepsin (a digestive enzyme), betaine hydrochloride (which boosts stomach acidity), pancreatin, and extracts from bovine and ovine spleen and pancreas. These are meant to support digestive function.

The product also contains a proprietary blend, which means some ingredient amounts aren't listed individually. The remaining ingredients are cellulose, lactose, and calcium stearate — inactive fillers and binders.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Digestive enzyme supplement for protein digestion.
  • We looked for evidence on: Dyspepsia, Indigestion, Bloating, Low stomach acid.
  • The closest evidence on file: Betaine Hydrochloride is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia (Natural Medicines).

The evidence for betaine hydrochloride's use in the conditions it's marketed for — indigestion, low stomach acid, diarrhea, and food sensitivities — is insufficient to rate. We hold no effectiveness data for the other active ingredients in this product.

That doesn't mean it doesn't work, just that reliable human studies backing its use aren't in our data.

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

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pepsin is generally well tolerated, though it may occasionally cause digestive upset or allergic reactions. Betaine hydrochloride can irritate the stomach and isn't safe if you have ulcers, gastritis, or acid reflux.

During pregnancy, betaine hydrochloride should be avoided because there isn't enough safety information. For pepsin and other ingredients, there's either little safety data in pregnancy and breastfeeding (pepsin has some reports), or no data on file for us to check — talk with your pharmacist or doctor before using this product if you're pregnant or nursing.

Side effects, ingredient by ingredient Proteolytic Enzymes (proteases) Betaine Hydrochloride

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 2 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.

Double-check this product before you start if you take H2-blockers (acid reducers like famotidine), antacids, or proton pump inhibitors (PPIs like omeprazole) — betaine hydrochloride may weaken their effects. No interactions are documented for pepsin or the other ingredients we could check.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

Zypan is a digestive enzyme and acid-support supplement. If you take acid-reducing medication (H2-blockers, antacids, or PPIs), you'll need to check whether this product might interfere — its betaine hydrochloride works against those drugs.

If you have stomach ulcers, gastritis, or acid reflux, skip it without medical advice. Ask your pharmacist if it fits your situation.

Zypan by SP Standard Process: Common Questions

Does Zypan by SP Standard Process interact with any medications?
Yes. Based on its ingredients, Zypan 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?
Zypan contains 8 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 work for indigestion or digestive problems?
The evidence for betaine hydrochloride — the main active ingredient you'd look for — isn't strong enough to rate. We don't hold effectiveness data for the digestive enzymes and spleen extracts in Zypan either. That said, no data doesn't mean it doesn't help; it just means reliable studies backing its use aren't in our database.
Can I take this if I'm on omeprazole or another acid-reducing medication?
Not without checking first. Betaine hydrochloride in Zypan works by increasing stomach acid, which can reduce how well acid-reducing drugs (PPIs, H2-blockers, antacids) do their job. Use the interaction checker on this page to search your exact medication.
Is pepsin safe?
Pepsin is generally well tolerated, but it may cause digestive upset or allergic reactions in some people. In rare cases, occupational exposure to airborne pepsin has triggered allergic rhinitis or asthma. If you have known protease allergies, mention it to your pharmacist.
Can I take this while pregnant?
No — betaine hydrochloride should be avoided in pregnancy because there isn't enough safety data. For pepsin and other ingredients, there's little to no safety information during pregnancy either. Talk with your doctor or pharmacist before using this product if you're pregnant.
Is this safe while breastfeeding?
The safety data during breastfeeding is limited or absent for the ingredients in Zypan. Betaine hydrochloride should be avoided, and there's not enough information on pepsin to recommend it without medical advice. Check with your pharmacist or doctor before nursing.
What does the 3X mean on pancreatin?
The 3X indicates a potency level — it's a standard way supplement makers mark enzyme strength. We don't hold effectiveness data for the pancreatin in this product, so I can't say how much digestive support that level provides.
