Top 5 Digestive Enzymes to Include in Your Supplement Routine

The pancreas works as your body’s digestive powerhouse. It makes enzymes that break down carbohydrates, proteins, and fats. Many people face digestive problems like bloating, excess gas, and acid reflux. This leads them to look for the best digestive enzymes that support their gut health.

Digestive enzyme supplements have become the most important solution to treat common gut irritation and help absorb nutrients better. These supplements lack FDA regulation but they help if you have specific health conditions. Take cystic fibrosis as an example – 90% of patients need pancreatic enzyme replacement therapy. This piece explores the best digestive enzymes you can add to your daily supplement routine. You’ll learn about their unique functions and ways they support optimal digestion.

Understanding Digestive Enzymes and Their Role in Gut Health

Digestive enzymes are biological catalysts that break down food into smaller components. They help your body absorb and use nutrients properly. These specialised proteins turn the food you eat into usable nutrients that power your daily activities and keep you healthy.

What are digestive enzymes?

These specialised proteins speed up chemical reactions in your body. They break complex food molecules into simpler forms that your body can use and absorb. You need these vital enzymes to digest food properly, whatever diet you follow.

Your body makes several types of digestive enzymes. Each enzyme targets specific food components:

  • Amylase: Breaks down complex carbohydrates and starches into simple sugars [1][2]
  • Lipase: Processes fats into fatty acids and glycerol [1][2]
  • Proteases and peptidases: Transform proteins into smaller peptides and amino acids [3][2][4]
  • Lactase: Specifically breaks down lactose (milk sugar) found in dairy products [4]
  • Sucrase: Breaks down sucrose (table sugar) into fructose and glucose [3]
  • Maltase: Converts maltose (malt sugar) into glucose [3]

Your body produces these enzymes throughout the digestive tract. Your mouth’s salivary glands release amylase that starts breaking down carbohydrates while you chew [2]. Your stomach makes some digestive enzymes, but your small intestine and pancreas produce most of them [5]. The pancreas acts as the enzyme “powerhouse” of digestion by flooding the small intestine with enzymes when food arrives [4][4].

Your digestive enzyme system responds to eating naturally. Enzymes release when you think about food, smell it, taste it, and throughout digestion [3]. This coordinated response breaks down all food components efficiently.

How digestive enzymes support nutrient absorption

Digestive enzymes help nutrients get absorbed by converting food into forms that can enter your bloodstream through the intestinal wall. This sophisticated process happens in multiple stages.

Food needs mechanical breakdown through chewing and chemical breakdown through enzyme action. These enzymes transform large, complex molecules into smaller ones that pass through your intestinal wall [4].

After digestive enzymes process your food, nutrients move from the intestinal lumen into your body through two main pathways:

  1. Paracellular pathway: Molecules move between intestinal epithelial cells through tight junctions to enter the extracellular space – a passive process regulated by electrochemical concentration gradients [4].
  2. Transcellular pathway: Molecules cross directly through intestinal cells by first traversing the apical membrane, then moving through the cell before crossing the basolateral membrane to enter the extracellular space [4].

The transcellular pathway handles most nutrient absorption, while the paracellular pathway manages some transport [4]. These nutrients enter your bloodstream through villous capillaries that carry them to your liver for processing and distribution [4].

Fat absorption works differently. Lipase breaks down fats into fatty acids and monoglycerides that enter intestinal cells. Some fatty acids go straight to the bloodstream. Others form triglycerides and chylomicrons that enter the lymphatic system through specialised ducts called lacteals [4].

You might experience various digestive issues and nutritional deficiencies without enough digestive enzymes. Common symptoms include: Abdominal pain or cramps

  • Bloating and excessive gas Diarrhoea
  • Oily stools
  • Unexplained weight loss [6]

Natural vs. supplement sources

Your body makes digestive enzymes naturally, but you can also get them from foods and supplements. Understanding these sources helps you make better decisions about your digestive health.

Natural enzyme sources from the body: Your body’s own enzymes work best for digestion [2]. A healthy digestive system usually makes enough enzymes without needing supplements. Your salivary glands, stomach, small intestine, and pancreas all make these enzymes [2].

Food sources of digestive enzymes: Several foods contain natural enzymes that might help digestion:

  • Raw honey contains amylase, protease, invertase, and diastase [2][2]
  • Pineapple provides bromelain, a powerful protease [3][2] 
  • Papaya contains papain, another effective protease [1][1] Avocados contain lipase [1][2]
  • Mangoes and bananas contain amylase [1][2]
  • Fermented foods like kefir, sauerkraut, and kimchi offer various enzymes including lipase, protease, and lactase [2][2][2]
  • Ginger contains zingibain, which helps digest proteins [5]

Scientists haven’t found much evidence that eating enzyme-rich foods significantly improves your digestive enzyme activity [2].

Supplement sources: Digestive enzyme supplements come in two types:

  1. Prescription enzymes: FDA regulates these medications like Pancreatic Enzyme Replacement Therapy (PERT). Doctors prescribe them for conditions like chronic pancreatitis, cystic fibrosis, and pancreatic insufficiency [2][4]. They contain specific amounts of amylase, lipase, and protease.
  2. Over-the-counter (OTC) supplements: These unregulated products vary in quality and composition [2][4]. Common OTC supplements include: Lactase supplements for lactose intolerance [4]
  • Alpha-galactosidase supplements ( for digesting gas-producing sugars in beans and certain vegetables [4]
  • Broad-spectrum enzyme blends targeting multiple food components [7]

Prescription enzymes can help people with diagnosed enzyme deficiencies when taken before meals [7]. OTC supplements might help with specific issues like lactose intolerance or bean digestion[1][4].

You should talk to healthcare professionals before using digestive enzyme supplements, especially if you have ongoing digestive symptoms or diagnosed digestive disorders.

Amylase: The Carbohydrate-Breaking Powerhouse

Carbohydrates are essential to most diets, yet many people struggle to digest them well. Amylase is pioneering carbohydrate digestion as the main enzyme that breaks down complex starches into simpler, more absorbable sugars. Understanding amylase’s key role is essential if you have the best digestive enzymes with Amylase to support your gut health.

How amylase works in your digestive system

Your carbohydrate digestion starts right in your mouth. Salivary glands release salivary amylase (also called ptyalin). This enzyme starts breaking down complex carbohydrates. It changes larger starch molecules (polysaccharides) into smaller ones called maltose and dextrin [8]. So, you need to chew properly—about 20 to 30 times per bite—to let this original enzymatic action happen [8].

After swallowing, partially digested food moves to the stomach, where gastric acid neutralises salivary amylase [9]. Many people think digestion stops in the stomach’s acidic environment. Yet under the right conditions, salivary amylase can keep breaking down up to 30-40% of eaten starches before becoming inactive [9].

Food then enters the small intestine (duodenum). The pancreas releases pancreatic amylase—the strongest form of this enzyme [9]. Unlike its salivary counterpart, pancreatic amylase works best in the small intestine’s slightly alkaline environment. Here it finishes breaking down remaining starches [9].

Scientifically speaking, amylase is an endoglycosidase enzyme in the hydrolase class. It catalyses the hydrolysis of 1,4-α-glucosidic linkages between adjacent glucose units in complex carbohydrates [9]. The enzyme acts differently on various carbohydrate structures:

  • With straight-chain polyglucans like amylose, amylase cleaves alternate α-1,4-hemiacetal links, forming maltose and some glucose [9]
  • For branched polyglucans such as amylopectin and glycogen, amylase generates maltose, glucose, and residual limit dextrins [9]

Other enzymes (maltase and isomaltase) then convert these broken-down carbohydrates into individual glucose molecules. Your intestinal wall absorbs these molecules [9]. This glucose ends up in your bloodstream, giving essential energy to your brain, nervous system, and cells throughout your body [9].

Benefits for bloating and gas reduction

Bloating and excess gas rank among the most common digestive complaints. These issues often stem from incomplete carbohydrate digestion. Unbroken carbohydrates travel to the large intestine. Here, gut bacteria ferment them and produce gas [8]. This fermentation process often causes uncomfortable bloating, flatulence, and digestive discomfort.

Amylase helps people with these symptoms by breaking down carbohydrates thoroughly. It ensures starchy foods turn into simple sugars before reaching the large intestine. This process helps reduce undigested carbohydrates available for bacterial fermentation [8].

Good amylase levels matter beyond comfort. Even healthy carbohydrate-rich foods can upset digestion without enough of this enzyme. Nutritious complex carbohydrates in whole grains, legumes, and certain vegetables need plenty of amylase to break down properly.

Digestive enzyme supplements with amylase might help if you suspect low amylase production. These supplements work with your body’s natural enzyme production to improve carbohydrate digestion [9]. Digestive enzymes supplements featuring amylase work particularly well if you get bloated after eating starchy foods.

Timing matters with these supplements. Research shows taking digestive enzyme supplements right before meals works best. This lets enzymes mix with food during digestion [9]. The timing matches your body’s natural digestive sequence, where amylase starts working in your mouth and continues through your digestive system.

Amylase affects more than just digestion. It changes how starchy foods feel in your mouth by making them thinner and potentially more enjoyable [10]. These texture changes might influence digestion since food consistency affects nutrient absorption and meal satisfaction.

Food sources of amylase

Your body makes amylase naturally, but some foods contain this enzyme too. These natural digestive enzymes can support digestive health alongside your body’s own enzyme production.

Fresh fruits, especially as they ripen, offer excellent natural amylase sources:

  • Mangoes contain amylase enzymes that become more active as the fruit ripens. They help break down complex carbohydrates into glucose and maltose [9]
  • Bananas provide both amylase and glucosidase that work together to break down complex starches into simple sugars [9]
  • Bananas and mangoes’ amylase becomes more active as they ripen, explaining their sweeter taste [9]

Several other foods contain amylase and related digestive enzymes:

Raw honey contains various digestive enzymes including diastase, amylase, invertase, and protease [9]. These enzymes give honey its digestive benefits, though heat can deactivate these sensitive enzymes.

Fermented foods also provide beneficial digestive enzymes including amylase:

  • Kefir (fermented milk) contains lipases, proteases, and lactases [9]
  • Sauerkraut (fermented cabbage) has many digestive enzymes [9]
  • Kimchi contains Bacillus bacteria that produce proteases, lipases, and amylases [9]
  • Miso (fermented soybeans) has lactases, lipases, proteases, and amylases from koji fungi used in fermentation [9]

Sprouted seeds, nuts, legumes, and whole grains often contain activated amylase [9]. Plants activate enzymes during sprouting to break down stored nutrients, making these foods easier to digest.

Scientists still debate how food-derived enzymes help digestion. These foods clearly contain active enzymes, but questions remain about their survival through stomach acid and activity in the intestines [9].

You might get the best digestive support by combining amylase-rich foods with well-timed digestive enzyme supplements. This approach matches traditional dietary wisdom with modern digestive science. It may ease common digestive problems while helping your body absorb nutrients better.

Lipase: Essential for Fat Digestion and Absorption

Fat digestion creates unique challenges for our body. The process needs special enzymes that turn dietary fats into nutrients we can absorb. Lipase plays a vital role here – it breaks down complex fat molecules so our body can extract essential fatty acids and fat-soluble vitamins from food.

The science behind lipase function

Lipase is part of an enzyme family that breaks down triglycerides (fats) into free fatty acids and glycerol through hydrolysis [8]. This key enzyme catalyses the breakdown of ester bonds in triglycerides. The process turns complex fat molecules into simpler components that our body absorbs and uses [8].

Our digestive system uses several types of lipase, each with its own job throughout the body:

  • Pancreatic lipase operates in the small intestine and plays the primary role in processing dietary fats [8]
  • Gastric lipase works in the stomach, initiating fat digestion by hydrolysing 10-20% of dietary triglycerides during the stomach trituration phase [11]
  • Hepatic lipase functions in the liver to break down triglycerides remaining in intermediate-density lipoproteins [8]
  • Hormone-sensitive lipase operates within adipose tissue, breaking down stored triglycerides in fat cells [8]
  • Lipoprotein lipase works within vascular endothelial cells to process circulating triglycerides [8]

The most important lipase starts working in the stomach and reaches peak activity in the small intestine. The liver’s bile mixes with pancreatic lipase in the duodenum (first section of the small intestine). This creates the perfect environment for fat digestion [9]. Bile salts do a critical prep job – they reduce fat droplets’ surface tension. This lets lipase enzymes access and break down triglyceride molecules better [12].

Lipase turns dietary fats into components that can cross the intestinal wall and enter our bloodstream. These fat components take a unique path compared to other nutrients after absorption through intestinal cells. Many reform into triglycerides, create structures called chylomicrons, and enter the lymphatic system through special ducts called lacteals.

This fat digestion process does more than just provide nutrition. It helps absorb essential fat-soluble vitamins (A, D, E, and K) that our body needs for many functions [9]. Low lipase activity means these vitamins can’t be properly extracted from food. This can lead to deficiencies even with a good diet.

Signs you might need lipase supplements

Low lipase production can affect both digestive comfort and nutrition by a lot. Our pancreas usually makes enough lipase to process dietary fats. Some health conditions might affect this vital function.

These signs often show you need lipase supplements:

  • Steatorrhoea (fatty, oily stools that float and are hard to flush)—shows fat isn’t being absorbed due to low lipase [9]
  • Stomach fullness and bloating after fatty meals [11]
  • Diarrhoea from undigested fats passing through your digestive tract [9]
  • Unexplained weight loss despite eating enough [9]
  • Deficiencies in fat-soluble vitamins (A, D, E, and K) despite eating right [8]

These medical conditions often link to lipase deficiency:

  • Pancreatic exocrine insufficiency (PEI) where your pancreas can’t make enough digestive enzymes [9]
  • Cystic fibrosis, which affects pancreatic function in about 90% of patients [9]
  • Chronic pancreatitis, which shows ongoing pancreas inflammation and calcification [8]
  • Crohn’s disease and celiac disease, which can affect overall digestive enzyme production [9]

Over-the-counter digestive enzyme supplements might help specific digestive issues. A small clinical study with 18 people showed supplements with lipase and other pancreatic enzymes reduced bloating, gas, and fullness after high-fat meals. These symptoms often come with irritable bowel syndrome (IBS) [9].

People without gallbladders might find lipase supplements especially helpful. The gallbladder normally stores and concentrates bile that helps digest fat [13]. Without it, bile release timing and concentration might be off, making lipase supplements particularly useful.

Optimal dosage recommendations

Your right lipase dose depends on your weight, health conditions, and what you eat. Lipase doses use lipase units instead of typical weight measurements like milligrammes.

Adults without specific health issues who sometimes feel digestive discomfort after fatty meals should follow these guidelines: Start with 10,000-20,000 lipase units for snacks and 20,000-40,000 lipase units for meals [9]

  • Take 2-3 capsules (usually 24,000-36,000 lipase units per capsule) with regular meals [8]
  • Use 1-2 capsules with snacks and smaller meals [8]

Doctors might recommend more specific doses for diagnosed pancreatic insufficiency: Weight-based: 2,500 lipase units per kilogramme of body weight per meal [8]

  • Fat content-based: 500-5,000 lipase units per gramme of fat in a meal [8]

A 68 kg (150 pounds) person could safely take up to 170,000 lipase units at one regular meal based on weight calculations [9]. All the same, never take more than 2,500 lipase units per kilogramme of body weight per meal without doctor supervision. Very high lipase doses might cause side effects [9].

Timing matters for digestive enzymes supplements to work best. Here are some guidelines:

  1. Take lipase supplements with your first bite—not before or after eating [9]
  2. Split the dose for big meals lasting over 30 minutes – take some capsules at start and some mid-meal [9]
  3. Take more capsules with fatty meals [9]
  4. Drink enough water with lipase supplements since low fluid intake might worsen constipation [9]

The best digestive enzyme supplements with lipase come as capsules. You can swallow them whole or open them to mix granules with acidic fluids or soft foods if swallowing is hard [9]. Mix with food and eat right away if opening capsules. Don’t crush or chew the granules – this breaks their protective coating that shields enzymes from stomach acid [9].

Your lipase supplement dose should match your needs. Watching symptoms and slowly adjusting the dose works better than strict dosing rules [9]. Doctor supervision becomes more important with higher doses or when treating specific conditions like chronic pancreatitis or cystic fibrosis.

These dosage guidelines give you the best chance at getting optimal digestive enzymes benefits from lipase while avoiding side effects. The right dose helps your body process dietary fats efficiently. This leads to better nutrient absorption and fewer uncomfortable digestive symptoms from incomplete fat digestion.

Protease: Breaking Down Proteins for Better Digestion

Proteins are vital macronutrients with complex molecular structures that need specific enzymes to break down and absorb properly. Proteases, also called proteolytic enzymes, are a complex family of digestive catalysts. These enzymes emerged during the earliest stages of protein evolution and break down dietary proteins into building blocks the body can use.

How protease enzymes work

Proteases help break down proteins by splitting peptide bonds. This process turns long protein chains into shorter peptides and individual amino acids [12]. Unlike how we digest carbs and fats, protein breakdown starts in the stomach. The enzyme pepsin kicks off this process in a highly acidic environment [14].

The digestive process continues in the small intestine where your pancreas releases several key proteases: 

  • Trypsin: Targets specific peptide bonds
  • Chymotrypsin: Breaks down proteins at different sites than trypsin
  • Carboxypeptidase: Removes amino acids from the ends of protein fragments [14]

Multiple enzymes working together give you complete protein digestion. Each protease targets different parts of the protein structure. This teamwork helps break down complex proteins from meat, eggs, fish, and plants quickly [12].

After proteases do their work, your small intestine’s microvilli absorb the amino acids and small peptides. These tiny projections increase the surface area to absorb more nutrients [14]. The amino acids then enter your bloodstream and help with growth, tissue repair, and many other key functions [12].

You might want to look for best digestive enzymes that contain multiple proteases to support better protein digestion.

Benefits beyond digestion: inflammation and immunity

Proteases do more than just break down proteins. Research shows these enzymes handle many complex tasks throughout your body. They help with DNA replication, cell growth, tissue repair, blood vessel formation, blood clotting, inflammation control, immune response, and cell death regulation [15].

These enzymes play a vital role in managing inflammation. Studies show that digestive enzymes supplements with proteolytic enzymes help reduce inflammation and its symptoms [16]. Bromelain, a protease from pineapple, helps reduce pain, swelling, and joint stiffness in people with osteoarthritis [16]. Proteases boost immune function by acting as signalling molecules through protease-activated receptors (PARs) [17]. This signalling affects white blood cell movement, cytokine production, and adhesion molecule expression—key parts of your immune response [17]. These enzymes help make complex immune reactions to threats work smoothly.

The digestive enzymes benefits reach into muscle recovery too. Research suggests proteolytic enzymes create bioactive peptides that help muscles recover and reduce damage after intense exercise [12]. Athletes and active people might find protease supplements helpful.

When to take protease supplements for maximum effect

Timing matters with protease supplements. Take proteolytic enzymes about 15 to 20 minutes before meals to help with protein digestion [12]. This ensures the enzymes are ready in your digestive system when food arrives.

Taking digestive enzyme supplements on an empty stomach works better for system-wide effects like reducing inflammation or supporting immune function [18]. The enzymes can enter your bloodstream instead of focusing on digestion.

You might need protease supplements if you notice: Bloating or gas after protein-rich meals

  • Undigested food in stool
  • Protein malnutrition despite eating enough protein Body-wide inflammation issues [19]

The best digestive enzyme supplements usually combine bromelain, papain, pancreatin, trypsin, and chymotrypsin for complete digestive support [12].

You can find natural digestive enzymes in certain foods. Pineapple (with bromelain) and papaya (with papain) pack plenty of proteolytic enzymes that may help digestion [20].

Lactase and Alpha-Galactosidase: Targeting Specific Food Intolerances

Food intolerances make life difficult for millions of people worldwide. Your body might struggle to break down certain foods, which leads to uncomfortable digestive symptoms. The good news is that enzyme supplements can help you deal with these common dietary challenges.

Managing dairy sensitivity with lactase

Lactose intolerance happens when your body doesn’t make enough lactase. This enzyme breaks down lactose (milk sugar) in dairy products. About 75% of people worldwide have this condition [11]. They experience tummy pain, bloating, gas, and diarrhoea after eating dairy products [21].

Lactase supplements help people with lactose intolerance. You can take lactase tablets right before eating dairy to prevent symptoms. These tablets break down lactose into simpler sugars that your body can digest [22]. Most people need 6,000 to 9,000 international units (IU) before eating dairy-containing meals [23].

Research shows lactase supplements make a real difference. They improve lactose breath test results and reduce gut symptoms substantially in people who can’t handle lactose [23]. Products like Lacto  have become popular digestive enzyme supplements that help manage dairy sensitivity.

Alpha-galactosidase for bean and legume digestion

Healthy foods like beans, lentils, cruciferous vegetables, and some grains contain complex carbohydrates called galacto-oligosaccharides (GOS). Our bodies can’t digest these naturally [2]. Even healthy people don’t produce alpha-galactosidase, an enzyme that breaks down these tricky compounds [2].

Alpha-galactosidase breaks down molecules from glycolipids and glycoproteins found in complex sugars [24]. This stops undigested carbs from reaching your large intestine where they would create uncomfortable gas.

A study with IBS patients showed promising results. Full-dose alpha-galactosidase treatment (300 GALU) helped people sensitive to GOS feel better [25]. Supplements like Beano are now accessible to more people who want relief from gas after eating beans and certain vegetables [11].

Combining enzymes for comprehensive digestive support

Multi-enzyme supplements are a great option if you have several food sensitivities. These formulas usually contain lactase to digest dairy, alpha-galactosidase to break down GOS, and other enzymes that help process proteins, fats, and carbohydrates [9].

These complete formulations give you several benefits:

  • They help balance gut bacteria and break down food [9]
  • They make digestion easier by breaking complex food molecules into simpler forms [9]
  • You can enjoy troublesome foods with less discomfort [8]

The best digestive enzyme supplements should include multiple enzymes that target your specific sensitivities. Take these supplements just before or during meals to get the best digestive enzymes benefits.

Conclusion

Digestive enzymes are the foundations of breaking down food and helping nutrient absorption in your digestive system. Different types of enzymes handle specific jobs. Amylase tackles carbohydrates, while lipase works on fats. Proteases break down proteins, and specialised enzymes like lactase and alpha-galactosidase take care of particular foods.

Your body makes these enzymes naturally. However, some health conditions or diet choices might mean you need supplements. People who experience bloating, gas, or trouble digesting certain foods often get relief from targeted enzyme supplements. Research shows these supplements work, especially when you have conditions like pancreatic insufficiency, lactose intolerance, or trouble with complex carbohydrates.

The right timing and dose are significant to get the most from enzymes. Taking supplements right before meals helps them interact best with food. The right combination of enzymes can address your specific digestive needs. Foods naturally rich in enzymes like pineapple, papaya, and fermented products can boost your supplement routine.

Matching specific enzyme types to particular digestive issues determines how well they work. Healthcare professionals can help you choose the right enzyme combinations based on your symptoms and medical conditions. Regular enzyme supplements, when needed, help keep your digestion comfortable and support nutrient absorption. This approach leads to better overall health.
