Digestive Enzymes

Table of Contents

Digestive enzymes are proteins that help break down the foods we eat into smaller molecules that can be absorbed and utilised by the body. They play a critical role in the digestive process by catalysing the chemical reactions that break down fats, proteins, and carbohydrates from the foods we consume.

The main digestive enzymes include:

  • Proteases – Break down proteins into amino acids
  • Lipases – Break down fats into fatty acids and glycerol
  • Amylases – Break down carbohydrates into simple sugars

These enzymes are primarily produced in the pancreas, small intestine, and mouth. Without enough digestive enzymes, undigested food particles can cause gastrointestinal issues like bloating, gas, and diarrhoea. Malabsorption of nutrients can also occur, leading to vitamin and mineral deficiencies over time.

Those with certain medical conditions like celiac disease, cystic fibrosis, and chronic pancreatitis are at risk for having low levels of digestive enzymes. The use of medications, ageing, and surgery can also impair enzyme production.

When the body lacks sufficient digestive enzymes, doctors may recommend enzyme supplements like protease, lipase, and amylase to aid digestion. These supplements provide the enzymes needed to properly break down and absorb nutrients from food.

Brief explanation of digestive enzyme deficiencies and why some people need to take supplements.

A deficiency in digestive enzymes can occur when the pancreas and small intestine don’t produce enough enzymes for proper digestion. This is often seen in those with pancreatic disorders like acute pancreatitis or chronic pancreatitis.

Without adequate enzymes, undigested food particles can irritate the intestinal lining and cause diarrhoea, gas, bloating, and abdominal discomfort. Nutrient malabsorption also frequently occurs.

Those with cystic fibrosis are prone to pancreatic enzyme deficiency as thick mucus obstructs the pancreas ducts. Other causes include celiac disease, small intestine surgery, and ageing.

To prevent malnutrition and nutrient deficiencies, doctors often prescribe pancreatic enzyme supplements to improve digestion and absorption. The supplements provide lipases, proteases, and amylases to properly break down fats, proteins and carbs from food.

When taken correctly, these supplements can help reduce gastrointestinal symptoms and ensure the body is absorbing essential vitamins and minerals.

Unpacking the Science Behind Digestive Enzyme Supplements

Digestive enzymes play a crucial role in breaking down the foods we eat into smaller nutrients that can be absorbed by the body. There are several types of digestive enzymes, each with a specific function in aiding digestion. Three key enzymes are amylase, protease, and lipase which help digest carbohydrates, proteins and fats respectively.

Protease is especially important for cleansing the gut and promoting a healthy inflammatory response. This enzyme breaks down proteins into smaller peptides and amino acids. Some research indicates that protease supplements can help reduce gut inflammation and clear out undigested protein waste that may accumulate in the intestines.

Studies also show that protease helps improve the absorption of vitamins, minerals and other nutrients by enhancing their bioavailability. This means more of the nutrients from foods can be utilised by the body rather than passing through undigested.

In addition, protease may help eliminate toxins and debris in the gastrointestinal tract. By helping clear out this unhealthy buildup, protease assists in maintaining the integrity of the gut lining and intestinal health.

Furthermore, protease supplements have been found to reduce certain food intolerances. Since protease improves protein digestion, it can lessen gastrointestinal distress caused by undigested protein particles. This makes protease a useful supplement for those with sensitivities to foods like dairy, eggs or gluten.

Overall, scientific research indicates protease and other key digestive enzymes play a vital role in optimising nutrient absorption, gut health, and healthy digestion. Supplementing with digestive enzymes can help enhance these processes, especially for those with enzyme deficiencies.

Understanding the Role of Protease, a Key Enzyme, in Cleansing the Gut from Inflammation and Waste

As a proteolytic enzyme, protease breaks down proteins into smaller chains of amino acids and peptides in the gastrointestinal tract. This allows for easier absorption of protein-derived nutrients.

Protease supplementation has been shown to reduce intestinal inflammation, a key factor in many chronic digestive issues. By breaking down inflammatory triggers like undigested protein particles, protease helps calm inflammation and promote gut barrier integrity.

Research also indicates protease can help eliminate mucus buildup and debris in the gastrointestinal tract. This debris can accumulate from undigested foods, bacterial overgrowth and intestinal inflammation. By helping clear out this unhealthy buildup, protease supports overall gut cleanliness and function.

Additionally, studies show protease supplements increase the bioavailability and absorption of vitamins, minerals and amino acids by breaking down antinutrient compounds that can bind them. This effect further optimises nutrient digestion and gut health.

In summary, the unique mechanisms of protease offer multifaceted benefits for cleansing the gut from inflammatory triggers, waste accumulation and antinutrient compounds. Supplementing with protease can support optimal protein digestion and absorption while promoting a healthy gut environment.

Benefits of Digestive Enzyme Supplements Beyond Deficiencies

Early research is beginning to suggest that digestive enzyme supplements may offer benefits even for those without enzyme deficiencies. While more studies are still needed, there are some promising indications that these supplements could improve nutrition absorption and support gut health in the general population.

One small study found that providing supplemental enzymes to healthy individuals increased the absorption of protein, fat, and carbohydrates. The researchers theorised this was because the enzymes helped break down food particles to smaller sizes, allowing for more efficient absorption in the small intestine.

Additional research indicates digestive enzymes may help reduce inflammation in the gut. Inflammation is linked to several chronic diseases and can be caused by factors like stress, poor diet, or food sensitivities. The anti-inflammatory effects of enzymes are thought to come from protease, which helps clear out undigested protein fragments before they can provoke an immune response.

There is also some evidence that supplementing with enzymes could support a healthy gut microbiome. The microorganisms in our digestive tract play crucial roles in immunity and nutrient absorption. In one study, a digestive enzyme blend helped rebalance gut bacteria in favour of more beneficial species.

While the research is still in early stages, these findings suggest digestive enzymes may impart advantages beyond just improving digestion. More studies are needed to confirm effects in the general population. But for some individuals, enzyme supplements could promote gut health and nutrient absorption even without an overt deficiency.

Who Should Consider Taking Digestive Enzyme Supplements

Certain groups may benefit more from taking digestive enzyme supplements than others. Individuals with digestive disorders like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and acid reflux often have symptoms related to poor digestion and may find relief through enzyme supplementation. Those with food intolerances, allergies, or who follow restricted diets like gluten-free may also improve digestion of problematic foods with enzymes.

Older adults tend to produce less enzymes naturally, so they are candidates for enzyme supplements to improve nutrient absorption. People who eat large amounts of cooked and processed foods could supplement since cooking destroys natural enzymes in foods. Vegetarians and vegans may need more enzymes to properly break down the fibre, protein, and carbohydrates in their plant-based diets.

Addressing Common Concerns

Some worry digestive enzymes will aggravate reflux, but they help break down food properly to reduce acid reflux in many cases. Starting with small doses and taking enzymes during or after meals can minimise side effects. While there is little evidence of long-term risks for most healthy adults, consult a doctor before taking enzymes if you have a chronic health condition or take medication.

For many, digestive enzymes provide a safe and natural way to find relief from gastrointestinal issues. However, work with a healthcare provider to determine if they are appropriate for your individual needs.

Choosing the Right Digestive Enzyme Supplement

When selecting a digestive enzyme supplement, it’s important to consider a few key factors to ensure you choose a high-quality product. Here is some guidance on what to look for:


Pay attention to the potency listed on the supplement label, which indicates the amount of active enzymes per capsule or serving. Higher potency products with at least 25,000 FCC units per capsule are recommended for optimal digestive support.


Look for a supplement with a blend of different digestive enzymes like amylase, protease, and lipase to help break down fats, proteins and carbs. Plant-based enzymes are preferable as they remain stable throughout the digestive tract.

Third Party Testing

Reputable brands will have their products tested by independent third party laboratories to verify quality and potency. This provides transparency and assurance that what’s on the label matches what’s in the bottle.


While cost is a consideration, don’t sacrifice quality to save money. High quality digestive enzymes are worth the investment for your health. Compare costs per serving when evaluating different brands.

Special Considerations

If you have specific digestive issues, look for targeted enzymes or probiotics to address your individual needs. For example, lactase for dairy digestion or alpha-galactosidase for gas and bloating.

Safety & Reputation

Only purchase from reputable manufacturers. Check for FDA-registered facilities and follow safe dosage recommendations. Consult your doctor before taking any new supplements.

By keeping these key factors in mind, you’ll be equipped to select the right high-quality digestive enzyme supplement to meet your needs and support your digestive health.


After reviewing the potential benefits of digestive enzyme supplements, it’s clear there are advantages for certain groups to consider these supplements. Those diagnosed with enzyme deficiencies can greatly benefit from targeted enzyme replacement therapy. Pancreatic enzyme supplements have been shown to aid digestion and nutrient absorption in these cases.

For individuals without deficiencies, early research also indicates digestive enzymes may support gut health, decrease inflammation, and relieve IBS symptoms. However, more studies are still needed to confirm these benefits for the general population.

When considering digestive enzyme supplements, consult with your healthcare provider first. They can help determine if you have a true enzyme deficiency that requires treatment. If you are cleared to try supplements, choose a high-quality brand with proper potency and ingredients.

The bottom line is digestive enzymes play a crucial role in the body. Supplementing enzymes under medical guidance may help manage certain conditions. But always discuss supplements with your doctor before starting any new regimen.
