Digestive Enzymes

Digestive enzymes are proteins that help break down food into absorbable nutrients. Over-the-counter blends may help with occasional gas, bloating, or fullness after meals when these sensations are related to incomplete digestion. Prescription pancreatic enzyme products (PERT) are different and are used for diagnosed pancreatic insufficiency under medical supervision. If symptoms persist or are severe, talk with your healthcare provider.

What Are Digestive Enzymes?

Digestive enzymes are proteins that break large food molecules, such as fats, proteins, and carbohydrates, into smaller molecules so the body can absorb them. This process is essential for nutrient absorption. Otherwise, the body cannot properly digest food particles, and food intolerance may occur. The main types of digestive enzymes include proteases (break down proteins), lipases (break down fats), and amylases (break down carbohydrates).

What Do Digestive Enzymes Do?

All enzymes are catalysts that can change molecules from one form to another. “Digestive enzymes” are enzymes used in the digestive system. These enzymes help reduce the size of the large macromolecules in foods so the intestine can absorb them.

Breaking down large molecules: These enzymes play a key role in breaking complex food molecules into smaller building blocks (amino acids, fatty acids, simple sugars) that are necessary for absorption through the small intestine.
Preventing digestive issues: Without enough digestive enzymes, food is not properly digested, and symptoms of indigestion and food intolerance may occur.

Where do digestive-enzyme supplements come from?

The digestive enzymes in supplements come from different sources. They may be sourced from the pancreas of animals such as pigs, cows, or lambs. Other enzyme supplements are plant-derived. For example, bromelain comes from pineapple. Papain comes from papaya. Lactase is obtained from purified yeasts or fungi. Supplements may contain a mixture of enzymes, such as:

Proteolytic enzymes like bromelain and papain, which are needed to digest protein
Lipase, which is needed to digest fat
Amylase, which is needed to digest carbohydrates

How do these enzymes work?

Digestion is a complex process that begins when chewing food releases enzymes in saliva. Most of the work is due to digestive tract fluids that contain digestive enzymes and act on certain nutrients such as fats, carbohydrates, and proteins. We make specific digestive enzymes to help absorb the different kinds of foods we eat. In other words, we produce specific enzymes for carbohydrates, proteins, and fats. Digestive enzymes are not only helpful, they are essential. They convert foods with complex structures into smaller components, including amino acids, fatty acids, cholesterol, simple sugars, and nucleic acids, which also help build DNA. Enzymes are produced and secreted in different parts of the digestive system, including the mouth, stomach, and pancreas.

Benefits of digestive enzymes

The simple answer is that without them, we cannot process food. However, there are several major reasons to have digestive enzymes:

By taking pressure off the digestive tract, they help with acid secretion issues
Match the enzyme to the food: lactase for dairy/lactose; lipase (often with bile salts) for higher-fat meals; proteases (e.g., bromelain, papain) for high-protein meals; and broad-spectrum blends for mixed meals. For gluten, only specific enzymes (e.g., AN-PEP) may help with small amounts and are not a substitute for a gluten-free diet in celiac disease.
May help with occasional meal-related discomfort (gas, bloating, fullness); individual response varies.
Increase nutrient absorption and help prevent nutritional deficiencies

Digestive enzyme supplements may also reduce your desire to eat and help treat constipation. If you do not have enough digestive enzymes to support digestion, you may develop constipation that improves with supplementation. However, enzymes are generally not associated with weight loss and are not intended for this purpose, although eating a healthy diet can support natural enzyme production, reduce inflammation, and help you reach a healthy weight. Digestive enzyme supplements may also reduce your desire to eat as much and help you consume an appropriate number of calories.

Who needs these enzymes?

How do you know if you should take digestive enzymes? If you need special enzymes to break down certain nutrients like some types of sugars, you may have symptoms such as bloating, gas, abdominal pain, and fatigue. Other signs that may result from not taking digestive-enzyme supplements include:

Acid reflux
Cravings for specific foods
Thyroid problems
Heartburn, indigestion, or belching
Thinning hair or hair loss
Dry or dull skin
Trouble concentrating
Morning fatigue
Sleep problems
Arthritis or joint pain
Muscle weakness or feeling tired after exercising
Mood swings, depression, or irritability
Headaches or migraines
Worsening PMS

Depending on how you view nutrients today, you can take a preventive or reactive approach to digestive-enzyme supplements. One viewpoint is “if it is not broken, do not fix it,” which suggests that if someone has no digestive concerns, enzymes are not needed. On the other hand, with nutrient deficiencies in diets and the surge of chronic diseases, a little extra help cannot hurt.

Frequently Asked Questions About Digestive Enzyme

What are digestive enzymes?

Proteolytic enzymes are taken away from meals for body-wide effects; they are not digestive aids.

When should I take digestive enzymes?

Usually with the first bite of food. Follow your product’s label. Some formulas are designed for snacks, others for larger meals.

What are systemic enzymes?

“Systemic” enzymes are proteolytic enzymes taken away from meals for body-wide effects. They are different from digestive enzymes taken with meals. Talk with your provider about whether that use is appropriate for you.

Do enzymes help with reflux or IBS?

Some people report improvement when meal-related symptoms are linked to poor digestion of certain foods. Results vary. Persistent heartburn, weight loss, anemia, or trouble swallowing needs medical evaluation.
