You ate a steak dinner at 7, but now It's 10, and it still feels like it's sitting right under your ribs.

That heavy, gassy, "why did I eat that?" feeling is what Standard Process Zypan® was made for. Here's what it is, how it works, how to take it, and who should pick something else.

Quick answer: Zypan is a digestive enzyme supplement from Standard Process. Each dose combines betaine hydrochloride (HCl), pepsin, and pancreatin to support protein digestion and a healthy stomach pH.* The label says to take 2 tablets with each meal and swallow them whole.

Shop Zypan: 90 tablets or 330 tablets.

What is Standard Process Zypan®?

Zypan is a digestive support supplement made by Standard Process. It's built to help your body break down the protein and fat in a meal.*

It does that with 3 main ingredients. Each one works in a different spot along your gut.

Ingredient	Where it works	What it does
Betaine HCl	Stomach	Supplies acid to support a healthy stomach pH, which your digestive enzymes need to work*
Pepsin	Stomach	Starts breaking protein into smaller pieces*
Pancreatin	Small intestine	A blend of amylase, protease, and lipase for starches, protein, and fat*

The tablets have an enteric coating. That coating helps the enzymes reach the right part of your gut instead of breaking down too early. It's also why you shouldn't chew them.

Full ingredient list (2 tablets): betaine hydrochloride, bovine pancreas Cytosol™ extract, pepsin (1:10,000), pancreatin (3x), stearic acid (vegetable source), ammonium chloride, bovine spleen, and ovine spleen. Other ingredients: cellulose and calcium stearate.

What is Zypan® used for?

People reach for Zypan when meals sit heavy. Think fullness that lingers, burping, or gas after a protein-heavy or fatty meal.*

The logic is simple. Protein digestion starts in your stomach, and it needs acid. Some people make less stomach acid as they get older, and when that happens, food can sit longer than it should.

Zypan adds the acid (betaine HCl) and the enzymes (pepsin and pancreatin) in 1 tablet. So it supports both steps at once.*

How to take Zypan

It's best to follow the directions on the label:

• Dose: 2 tablets with each meal, or as your practitioner directs.
• Timing: With your meal(s). The enzymes need food to work on.
• Don't chew it. Swallow the tablets whole so the coating can do its job.

How long does a bottle last? At the full label dose (2 tablets, 3 meals a day), you'll use 6 tablets a day.

If you only take it with your biggest meal, a bottle lasts 3 times as long. Ask your practitioner which approach fits you.

Zypan side effects: is there a downside?

Most people take Zypan without any trouble, but betaine HCl is an acid, and that matters for some stomachs.

Possible side effects include heartburn, a warm or burning feeling in the stomach, nausea, or loose stools. If you notice any of these, stop taking it and check with your practitioner.

Skip Zypan (or ask first) if you:

• Have a history of ulcers, gastritis, or frequent heartburn. Extra acid can make these worse.
• Take NSAIDs (like ibuprofen) or steroids daily. These can already irritate the stomach lining.
• Are pregnant or nursing.
• Avoid animal products. Zypan contains bovine (cow) and ovine (sheep) ingredients, so it isn't vegetarian or vegan.
• Have a serious food allergy. It's made in a facility that also processes soy, milk, egg, wheat, peanut, tree nuts, fish, and shellfish.

Is Zypan good for GERD or heartburn?

If you deal with GERD or regular heartburn, talk with your provider before taking Zypan. It adds acid to your stomach, and that's the opposite of what most heartburn sufferers want.

The better fit is usually Zymex® II. It has plant enzymes and no betaine HCl or pancreatin, which is why Standard Process calls it appropriate for acid-sensitive people.

Zypan vs. plain betaine HCl

Standard Process also sells Betaine Hydrochloride on its own. It gives you the acid without the pepsin or pancreatin.

Zypan is the all-in-one option. Plain betaine HCl is for people whose practitioner wants to adjust the acid dose alone. Our guide to betaine HCl supplements covers how that works.

Where to buy Standard Process Zypan®

Standard Process sells through health care practitioners. Snow Holistic Health is a practitioner-run clinic in Lake Charles, Louisiana, and we stock Zypan in 2 sizes:

Zypan Frequently Asked Questions

What are the side effects of Zypan?

Possible side effects include heartburn or a burning feeling, nausea, cramping, loose stools, constipation, and gas. They come mostly from the betaine HCl (acid) and the digestive enzymes. Stop taking it and check with your practitioner if you notice any.

Is Zypan safe?

For most healthy adults at the label dose, yes. Skip it or ask your provider first if you have ulcers, gastritis, or frequent heartburn, take NSAIDs or steroids daily, or are pregnant or nursing.

What does Zypan do?

Zypan supports protein digestion and a healthy stomach pH.* It combines betaine HCl, pepsin, and pancreatin, so it works in both the stomach and the small intestine.

Is Zypan a digestive enzyme?

Yes. Zypan contains the digestive enzymes pepsin and pancreatin (amylase, protease, and lipase). It also contains betaine HCl, which supplies the acid those enzymes need.
