What’s The Difference Between Probiotics and Digestive Enzymes?

Your digestive system performs an incredible amount of work every day. It breaks food into nutrients, absorbs what your body needs, and helps move waste through the digestive tract. When digestion is not working comfortably, symptoms such as bloating, gas, diarrhea, constipation, or stomach discomfort can quickly affect your day.

Probiotics and digestive enzymes are often discussed together because both are connected to digestion. However, they are not the same thing, and they perform very different jobs inside the body.

Probiotics are living microorganisms that may support the community of microorganisms in your digestive tract. Digestive enzymes are proteins that help break food into smaller components that your body can absorb. Understanding the difference can help you make more informed decisions about your digestive health.

What Are Probiotics?

Probiotics are live microorganisms that may provide a health benefit when consumed in appropriate amounts. They are often described as beneficial bacteria, although some probiotics are yeasts.

Your digestive tract naturally contains a large and diverse community of microorganisms. This community is commonly known as the gut microbiome. These microorganisms interact with your digestive system and may influence digestion, immune function, and other processes throughout the body.

According to the National Center for Complementary and Integrative Health, probiotics can be found in certain fermented foods and dietary supplements. However, not every fermented food automatically contains probiotics that have been shown to provide a specific health benefit.

Different probiotic products may contain different strains and amounts of microorganisms. This matters because the effects of one probiotic strain cannot always be applied to another strain.

What Do Probiotics Do?

Researchers are continuing to study how probiotics affect the digestive system. Certain probiotic strains may help support the balance of microorganisms in the gut, especially after that balance has been disrupted.

Some probiotics have been studied for concerns such as antibiotic associated diarrhea, symptoms of irritable bowel syndrome, and certain other digestive conditions. However, the results vary by strain, health condition, dosage, and the individual taking the product.

Probiotics should not be treated as a guaranteed cure for bloating, constipation, diarrhea, or other digestive symptoms. A product that helps one person may not provide the same benefit to someone else.

What Are Digestive Enzymes?

Digestive enzymes are proteins that help your body break food into nutrients small enough to be absorbed. Your body naturally produces several types of digestive enzymes in the mouth, stomach, pancreas, and small intestine.

The National Institute of Diabetes and Digestive and Kidney Diseases explains that the digestive system breaks nutrients into parts that are small enough for the body to absorb and use for energy, growth, and cell repair.

Some of the major digestive enzymes include:

• Amylase: Helps break carbohydrates and starches into simpler sugars.
• Protease: Helps break proteins into amino acids.
• Lipase: Helps break fats into fatty acids and glycerol.
• Lactase: Helps digest lactose, the natural sugar found in milk and dairy products.
• Sucrase: Helps break sucrose into simpler sugars.

Most healthy people naturally produce the digestive enzymes they need. Digestive enzyme supplements are not routinely necessary for everyone.

The Main Difference Between Probiotics and Digestive Enzymes

The easiest way to understand the difference is to look at what each one is and what it does.

Probiotics	Digestive Enzymes
Living microorganisms	Proteins produced by the body
May support the gut microbiome	Break food into absorbable nutrients
Found in certain fermented foods and supplements	Produced in the mouth, stomach, pancreas, and small intestine
Benefits depend on the specific strain	Each enzyme breaks down a particular type of nutrient
Not required to digest every meal	Essential to the normal digestive process

Probiotics do not directly break your meal into nutrients. Digestive enzymes do not add beneficial bacteria to your intestinal microbiome.

They may both be associated with digestive health, but they do not perform the same function and should not be used interchangeably.

Do Probiotics and Digestive Enzymes Work Together?

Probiotics and digestive enzymes can exist in the digestive system at the same time, but it is misleading to say that one cannot work without the other.

Your digestive enzymes break food into nutrients. Meanwhile, the microorganisms living in your digestive tract interact with substances that reach the intestines. Each plays a role within the broader digestive environment, but their jobs are different.

A healthy person does not usually need to take both probiotic and digestive enzyme supplements. Whether either type of supplement is appropriate depends on the person’s health, symptoms, diet, medications, and medical history.

Where Can You Find Probiotics?

Some foods are produced through fermentation and may contain live microorganisms. Possible food sources include:

• Yogurt containing live and active cultures
• Kefir
• Refrigerated sauerkraut containing live cultures
• Kimchi
• Miso
• Tempeh
• Some fermented pickles
• Some traditional fermented beverages

Heating, pasteurization, and food processing may destroy live microorganisms. For that reason, not every yogurt, pickle, or fermented product contains live probiotic cultures by the time it is eaten.

Read the product label and look for language such as “live and active cultures.” Probiotic supplements may be available in capsules, powders, liquids, gummies, and other forms.

Do You Need a Probiotic Supplement?

Probiotic supplements are widely available, but more is not always better. Different products contain different organisms, and the number listed on the package does not guarantee that the product will help with a particular health concern.

The NCCIH probiotic guidance notes that strong scientific evidence is lacking for many conditions. Researchers are still learning which probiotics may be helpful, how much should be used, and who is most likely to benefit.

Probiotics are generally well tolerated by many healthy people, but they may cause temporary gas or digestive discomfort. People who are seriously ill, have weakened immune systems, have recently undergone surgery, or are caring for a premature infant should speak with a physician before using probiotics.

Do You Need Digestive Enzyme Supplements?

Most people do not need a general digestive enzyme supplement to digest an ordinary meal. However, specific enzymes can be helpful when a person does not produce enough of a particular enzyme or has a diagnosed medical condition.

For example, people with lactose intolerance may use lactase products to help digest dairy foods. People with exocrine pancreatic insufficiency may require prescription pancreatic enzyme replacement therapy.

The NIDDK explains pancreatic enzyme replacement therapy as a prescribed treatment that helps people with pancreatic insufficiency digest food and absorb nutrients.

Prescription pancreatic enzymes are different from general digestive enzyme supplements sold online or in stores. Prescription treatment is carefully selected and monitored by a physician.

Do not assume that recurring bloating, pain, greasy stools, unexplained weight loss, chronic diarrhea, or other persistent symptoms simply mean that you need an enzyme supplement. These symptoms may have several possible causes and should be discussed with a qualified health care provider.

Can You Take Probiotics and Digestive Enzymes Together?

Some commercial supplements combine probiotics and digestive enzymes in one product. However, combining them does not automatically make a supplement more effective.

Taking both may be appropriate in certain situations, but it depends on why you are taking them. A person using lactase for lactose intolerance has a very different need from someone considering a probiotic after taking antibiotics.

Before combining supplements, speak with your doctor, pharmacist, or registered dietitian, particularly if you:

• Take prescription medications
• Are pregnant or breastfeeding
• Have a weakened immune system
• Have a pancreatic or digestive condition
• Are preparing for surgery
• Experience chronic or severe digestive symptoms
• Are considering giving supplements to a child

Probiotics Are Not the Same as Prebiotics

Probiotics and prebiotics are also commonly confused.

Probiotics are live microorganisms. Prebiotics are substances, often certain types of dietary fiber, that are used by microorganisms in the digestive tract.

Foods that may provide prebiotic fiber include onions, garlic, asparagus, bananas, oats, beans, and certain whole grains. Eating a varied diet that contains fruits, vegetables, legumes, and whole grains can help provide fiber that supports digestive health.

How to Support Healthy Digestion Naturally

Supplements are only one small part of the digestive health conversation. Everyday habits may have a much larger effect on how you feel.

• Eat a varied diet that includes fruits, vegetables, whole grains, and other fiber rich foods.
• Drink enough water throughout the day.
• Increase dietary fiber gradually to reduce discomfort.
• Exercise regularly according to your ability.
• Chew food thoroughly and avoid rushing through meals.
• Pay attention to foods that repeatedly trigger symptoms.
• Get adequate sleep.
• Discuss persistent digestive problems with your physician.

The digestive system includes the gastrointestinal tract, liver, pancreas, and gallbladder. These organs work together to digest food and absorb nutrients. You can learn more by visiting the NIDDK digestive diseases resource center.

How to Choose a Supplement Carefully

Dietary supplements are regulated differently from prescription medications. A product being sold in a store or online does not automatically mean it has been proven effective for every claim printed on the packaging.

The U.S. Food and Drug Administration advises consumers to talk with a health care professional before using dietary supplements, especially when combining them with medications.

When considering a probiotic, look for a label that clearly identifies the genus, species, and strain. The label should also provide storage instructions and an expiration or use by date.

When considering a digestive enzyme product, look for the specific enzyme it contains and the reason it is being used. Avoid products that promise to cure numerous unrelated conditions or claim to work for everyone.

When to Contact Your Doctor

Occasional gas or bloating may occur for many reasons. However, ongoing digestive symptoms deserve attention, especially when they interfere with eating, sleeping, working, or normal daily activities.

Contact a health care professional if you experience:

• Severe or persistent abdominal pain
• Blood in the stool
• Black or tarry stool
• Frequent vomiting
• Ongoing diarrhea or constipation
• Unexplained weight loss
• Difficulty swallowing
• Greasy or unusually pale stools
• Signs of dehydration
• Digestive symptoms accompanied by fever

These symptoms should not be managed by experimenting with supplements alone.

Understanding Which One You May Need

Probiotics and digestive enzymes both have connections to digestion, but they are not interchangeable. Probiotics are live microorganisms that may support the gut microbiome. Digestive enzymes are proteins that break food into nutrients your body can absorb.

Many people can support their digestive health through a balanced diet, adequate fiber, hydration, regular movement, and appropriate medical care. Supplements may be helpful in specific situations, but they should be selected based on a clear need rather than advertising claims.

Before starting a probiotic or digestive enzyme supplement, consider discussing your symptoms and goals with a physician, pharmacist, or registered dietitian. That conversation can help you choose an option that is appropriate for your health rather than simply purchasing the most popular product.
