The digestive enzymes benefits market continues to boom, and experts predict sales will hit £1.6 billion by 2025. More people now understand these vital proteins’ role in nutrient absorption and digestive health.
Your body might not absorb nutrients well even from healthy food without proper digestive enzymes. Your pancreas makes significant enzymes like amylase, lipase, and protease that break down carbohydrates, fats, and proteins. Some health conditions can reduce enzyme production and cause bloating, gas, and unexpected weight loss.
This piece explains digestive enzymes, their types, and ways to pick the right supplement that matches your digestive needs. You’ll discover the right doses, potential risks, and natural food options to boost your digestion.
What Are Digestive Enzymes and How Do They Work?
Digestive enzymes act as biological catalysts that speed up chemical reactions in your body by a lot. These specialised proteins turn food into nutrients your body can absorb through an amazing process that happens every time you eat.
The science behind food breakdown
Your body uses two different processes that work together to digest food: mechanical and chemical digestion. The mechanical process breaks food into smaller pieces physically, while chemical digestion uses enzymes that turn complex molecules into simpler forms your body absorbs [1]. This amazing transformation starts right when food enters your mouth.
The moment you take that first bite, your salivary glands release amylase to break down starches. This enzyme starts carbohydrate digestion before the food reaches your stomach [2]. Your stomach’s protease enzymes, like pepsin, then start breaking down proteins [1].
Your pancreas makes most of these enzymes, which makes it the “powerhouse” of digestion [2]. These enzymes flow into the small intestine where less acidic conditions—a pH of 6 to 7—create the perfect environment for them to work [2].
These digestive powerhouses use a “lock and key” model to do their job. Each enzyme’s active site has a unique shape that matches its target food molecule (substrate) perfectly, just like a key fits its lock [1]. This perfect match helps break down different nutrients efficiently.
Key types of digestive enzymes in your body
Your body uses several major enzyme categories to handle different parts of your diet:
Carbohydrate-digesting enzymes:
- Amylase (mouth, pancreas): Breaks down starches into sugars [1]
- Maltase (small intestine): Converts maltose to glucose [2]
- Lactase (small intestine): Breaks down lactose in dairy products [3]
- Sucrase (small intestine): Converts sucrose to glucose and fructose [2]
Protein-digesting enzymes:
- Proteases (stomach, pancreas): Include pepsin, trypsin, chymotrypsin, and elastase [2]
- These enzymes turn proteins into amino acids by targeting different peptide bonds [2]
Fat-digesting enzymes:
- Lipase (pancreas, small intestine): Breaks down fats into fatty acids and glycerol [1]
- Works with your liver’s bile to emulsify fats for better digestion [2]
Your digestive system makes many more specialised enzymes to handle specific food components. Alpha-galactosidase, to cite an instance, helps break down complex sugars in beans and legumes, which prevents digestive discomfort.
How enzyme deficiency affects digestion
Your digestive health and overall wellbeing can suffer a lot if your body doesn’t make enough enzymes. These deficiencies stop foods from breaking down properly, which leads to poor absorption of vital nutrients [4].
Lactose intolerance shows what happens in one of the most common enzyme deficiencies. People who lack enough lactase enzyme can’t digest dairy’s lactose properly. The undigested lactose moves to the colon, mixes with bacteria, and creates uncomfortable symptoms [5]. Most people notice bloating, gas, and diarrhoea after eating dairy products.
Exocrine pancreatic insufficiency (EPI) happens when your pancreas doesn’t produce enough digestive enzymes. This condition disrupts the digestion of multiple nutrients at once, and you might become malnourished even with a healthy diet [4].
You might notice these common symptoms with enzyme deficiencies:
- Bloating and excessive gas that won’t go away
- Stomach pain or cramping after meals
- Diarrhoea or oily-looking stools (steatorrhoea)
- Food that hasn’t digested in your stool
- Weight loss you can’t explain despite eating enough [4]
Your enzyme production might drop due to health conditions like chronic pancreatitis, cystic fibrosis, pancreatic cancer, and diabetes [4]. Some people also see reduced enzyme levels after gut surgeries.
Common Signs You Might Need Digestive Enzyme Support
Your body sends clear signals when it lacks digestive enzymes. Early detection of these signs helps identify enzyme deficiencies so you can take action quickly. These common indicators suggest you might need digestive enzyme support.
Persistent bloating and gas
Bloating makes your stomach feel full, tight or swollen and ranks among the most frequent digestive complaints. Everyone deals with occasional bloating, but ongoing bloating points to digestive problems.
Digestive enzymes are vital components that break down food particles properly. Food moves to the large intestine partially digested when enzymes are insufficient. Bacteria then ferment this food and produce excess gas. This process guides many people to feel uncomfortable after meals.
Different enzyme deficiencies create distinct bloating patterns. People who lack lactase feel bloated right after having dairy products. Insufficient amylase causes bloating after starchy meals, while lipase deficiency brings discomfort after fatty foods [7].
Your bloating needs medical attention if it lasts more than three weeks or happens often (over 12 times monthly) [8]. This might indicate you need enzyme supplements.
Undigested food in stool
Food particles in your stool might show that your system doesn’t break down food properly. Some undigested food—especially high-fibre vegetables—is normal, but regular sightings of substantial undigested matter point to enzyme insufficiency [9].
Food passes through your digestive system without proper breakdown when enzyme levels are low. Specific deficiencies show distinct patterns:
- Lipase deficiency results in greasy, foul-smelling stools [7]
- Amylase insufficiency leaves carbohydrates undigested [7]
- Protease inadequacy means proteins don’t break down well [7]
Several conditions like pancreatic insufficiency, celiac disease, or inflammatory bowel disease often cause undigested food in stool [9]. Weight loss, ongoing diarrhoea, or changes in bowel habits alongside this symptom might mean malabsorption that needs medical care.
Food intolerances and sensitivities
Enzyme deficiencies directly cause many food intolerances. Unlike allergies that trigger immune responses, intolerances happen when your body can’t digest certain food components due to missing enzymes [10].
Common enzyme-related intolerances include:
- Fructose intolerance affects fruit sugar digestion
- Alpha-galactosidase deficiency impacts bean and legume processing
- Sucrase-isomaltase deficiency prevents proper digestion of table sugar and some starches [7]
Research shows that 20% of people have some type of food intolerance [6]. An enzyme deficiency might be the root cause if specific foods consistently upset your digestion.
Fatigue after meals
Unusual tiredness after eating protein or carb-rich meals might indicate enzyme insufficiency. Mild post-meal sleepiness is normal, but extreme fatigue suggests digestive problems [11].
Your body works overtime to break down food when enzyme levels are low. This extra effort depletes energy substantially as your system struggles to extract nutrients from food.
Poor digestion from enzyme insufficiency often prevents proper nutrient absorption. Vitamin and mineral deficiencies can develop even with healthy eating habits if your body can’t process nutrients properly [11]. This often shows up as constant tiredness, weakness, or low energy after meals.
Digestive enzyme supplements might help if meals regularly leave you tired—especially when bloating, stomach discomfort, or other digestive symptoms occur too. These supplements support your body’s natural digestive processes effectively.
Different Types of Digestive Enzyme Supplements
The market offers countless digestive enzyme supplements, which makes choosing the right one quite challenging. Let’s explore the different types to help you find a supplement that matches your digestive needs.
Plant-based vs. animal-derived enzymes
The source of digestive enzymes plays a crucial role in how they work and suit different people. Animal-derived enzymes come from cow and pig pancreas and stomach lining [12]. These enzymes match human digestive enzymes closely, which makes them helpful if you have enzyme deficiencies [12]. Notwithstanding that, they work best at higher pH levels and don’t work very well in the stomach’s acidic environment [12].
Plant-based enzymes bring their own set of benefits. These enzymes, which come from papaya and pineapple, stay active in different pH levels [12]. This exceptional quality lets them work throughout your digestive system. They start working right in your stomach instead of waiting to reach your small intestine [2].
Plant-based options give vegans and vegetarians an ethical choice instead of animal-derived supplements. Pineapple’s bromelain and papaya’s papain are popular plant-derived enzymes [2]. Your digestive system handles these enzymes better, and they help break down plant-based foods effectively [12].
Fungal enzymes make up another important group. These enzymes come from fermenting Aspergillus [2]. Much like plant enzymes, they work well at different pH levels throughout your digestive system [2]. These vegan-friendly options pack proteases, amylases, lipases and cellulases [2].
Broad-spectrum formulas
Broad-spectrum enzyme supplements combine multiple enzymes to tackle various digestive issues at once. These detailed formulations usually contain:
- Protease to break down proteins
- Amylase to digest carbohydrates and starches
- Lipase to digest fats
- Cellulase to break down fibre
- Lactase to digest dairy
Enzalase by master supplements shows this integrated approach with six key enzymes: protease, amylase, alpha-galactosidase, lipase, hemicellulase and lactase [5]. Plant enzyme digestive formula by designs for health® also offers various plant-sourced enzymes that help digest protein, fat and carbohydrate [13].
These detailed formulas help people who have multiple food sensitivities or general digestive problems. Each enzyme in these blends works with others to improve your overall digestion [5]. These broad-spectrum supplements serve as a great starting point when you begin taking enzyme supplements.
Targeted single-enzyme products
Targeted single-enzyme supplements offer specific solutions for particular digestive issues. Lacto by Enzymedica contains lactase to help with lactose intolerance, which affects much of the world’s population (up to 75%) [14]. Taking these supplements before dairy helps break down lactose and prevents gas and bloating.
Complete Enzymes by Amy Myers MD contains alpha-galactosidase that breaks down tough fibres in beans, root vegetables and some dairy products [14]. This helps about 20% of people who get stomach pain from gas because they can’t digest complex carbohydrates well [14].
The market has seen new specialised enzyme products for specific dietary challenges. Your specific digestive challenges determine whether broad-spectrum or targeted enzyme supplements work better for you. Knowing your food sensitivities helps you pick the right enzymatic support.
Matching Specific Enzymes to Your Digestive Complaints
Matching the right enzyme to your digestive problems helps you find targeted relief through supplements. This targeted approach works better than just taking random digestive aids.
Lactase for dairy intolerance
People worldwide struggle with lactose intolerance. Your body might not make enough lactase to digest the lactose in milk and dairy products [15].
Taking lactase supplements fills in for the missing enzyme. These supplements help break down lactose properly and stop those uncomfortable symptoms like bloating, gas, and diarrhoea. You can find them as tablets, capsules, or drops to add straight to milk [16].
The best results come from taking lactase supplements right before eating dairy foods. Most people need between 6,000 to 9,000 international units (IU). Start with less and work your way up based on what your body needs [17].
Studies back up how well lactase supplements work. A test showed that taking them 15 minutes before meals helped people digest lactose just as well as probiotics
[17]. Notwithstanding that, everyone responds differently – some people feel completely better while others see only some improvement.
Amylase for carbohydrate digestion
Amylase is a vital player in breaking down complex carbs and starches into simpler sugars. Your body makes this enzyme in two places: your salivary glands and pancreas [18].
Food digestion starts the moment you take a bite. Salivary amylase breaks down starches while you chew and as food moves down your oesophagus. Your pancreatic amylase then finishes the job in your small intestine, turning complex carbs into dextrin and maltose [19].
Amylase supplements might help if starchy foods like potatoes, rice, or bread leave you bloated or uncomfortable. Without enough amylase, partially digested carbs reach your large intestine where they create gas and discomfort.
Lipase for fat digestion issues
Lipase enzymes turn fats into glycerol and fatty acids that your gut can absorb. These enzymes come from your pancreas, mouth, and stomach [4].
Your pancreas usually makes enough lipase naturally. Some conditions can lower lipase production, such as cystic fibrosis, Crohn’s disease, and celiac disease [4]. Watch for signs like greasy, smelly stools, bloating after fatty meals, and unexplained weight loss despite eating normally.
Research supports using lipase supplements for specific digestive complaints. A small study with 18 people showed that supplements with lipase and other pancreatic enzymes substantially reduced bloating, gas, and fullness after high-fat meals [4]. Another study found acid-resistant lipase supplements substantially decreased stomach fullness 20 and 30 minutes after fatty meals [20].
Proteases for protein breakdown problems
Proteases make up about 2% of all proteins your genes code for, showing how important they are [21]. These special enzymes break proteins into smaller peptides and amino acids.
Proteases do more than help digestion – they help cells grow, support immune responses, and heal wounds [22]. Your digestive system’s main protein-breaking enzymes include pepsin from your stomach and trypsin and chymotrypsin from your pancreas [23].
Not having enough protease can mean protein doesn’t digest well, leading to bloating, gas, and stomach discomfort after protein-rich meals. These supplements help especially when you have a high-protein diet or trouble digesting foods like meat, eggs, and fish.
Alpha-galactosidase for bean and legume digestion
Alpha-galactosidase breaks down complex carbs found in beans, legumes, cruciferous vegetables, and certain grains [24]. These foods contain oligosaccharides – complex sugars that humans don’t deal very well with, often causing gas and bloating.
Digest Spectrum supplement with alpha-galactosidase, helps prevent gas and gut symptoms from high-fibre diets [25]. Taking these supplements before eating problem foods helps break down oligosaccharides into simple sugars before they hit your colon, stopping uncomfortable gas and bloating [24].
The best carbohydrate digestion support often comes from supplements with multiple enzymes. Studies suggest combining alpha-galactosidase with amylase, cellulase, and sucrase works better than using alpha-galactosidase alone [24].
How to Read and Understand Enzyme Supplement Labels
You need to understand how to read supplement labels to pick the right digestive enzyme supplement. The technical terms and measurements on these labels often leave consumers feeling lost. Getting the full picture of labelling standards helps you find a supplement that works for your digestive needs.
Identifying quality markers
Third-party certifications are vital quality indicators. Organisations like the Clean Label Project test supplements independently for contaminants such as heavy metals, pesticides, and plasticizers [1]. These certifications give you more than just the manufacturer’s word.
The best supplements list each enzyme with its activity units clearly instead of hiding behind proprietary blends [26]. On top of that, it helps to check storage instructions and expiry dates because enzymes lose strength over time, especially in bad conditions [7].
Enteric coating stands out as another quality feature. This special coating shields enzymes from stomach acid so they reach the small intestine where they do most of their digestive work [29]. Many enzymes break down before reaching their target without this protection.
Checking allergen information becomes essential if you have sensitivities. Quality enzyme supplements tell you clearly if they contain common allergens like egg, dairy, nuts or gluten [27]. Vegetarians and vegans should also look at capsule ingredients since some use animal-derived gelatin instead of plant-based options like cellulose [27].
Red flags to watch for
Stay away from supplements that make bold promises. Some products claim they’ll help you lose weight substantially or give you a flat stomach – claims that science doesn’t support [30]. Note that healthy people with normal digestion usually don’t need enzyme supplements [30].
Look closely at the “other ingredients” section. Some products contain additives that might cause problems, like maltodextrin, fructose, glucose or artificial sweeteners [27]. Too many fillers not only weaken active ingredients but can upset your digestion [26].
Don’t trust products that claim to fix conditions without proper medical diagnosis. While occasional digestive discomfort might improve with over-the-counter enzymes, you should see a doctor about ongoing symptoms before trying to treat them yourself [32].
Timing and Dosage: Maximising the Benefits of Digestive Enzymes
The right timing and correct dosage make digestive enzyme supplements work better. Quality enzymes might not give you their full benefits without these key factors.
Before, during or after meals?
You should take digestive enzymes 15 to 30 minutes before a meal [8]. This timing lets enzymes mix with stomach juices before food arrives, which helps them work better. When you take enzymes at this exact time, they’re ready to break down nutrients as soon as you start eating.
Your timing might need adjustment based on specific food intolerances. Here’s what works best:
- Take lactase right before dairy products
- Use alpha-galactosidase right before eating beans or legumes
- Add protease supplements with protein-rich foods [6]
Long meals or multiple courses might need a different approach. You’ll get better results if you split your enzyme dose – half at the start and half midway through the meal [33]. This method works especially well for meals that last more than 30 minutes.
Did you forget to take your enzymes before eating? Taking them shortly after might still help, especially if you feel bloated or have indigestion [8].
Starting doses for beginners
New users should start with lower doses to let their body adjust. Most people do well with 10,000-20,000 lipase units for snacks and 20,000-40,000 lipase units for meals [34]. You can adjust these amounts based on how your body responds.
Safety matters – experts say not to take more than 2,500 lipase units per kilogramme of body weight per meal [34]. A person weighing 68kg (150 pounds) could safely take up to 170,000 lipase units in one meal.
Most over-the-counter supplements suggest 1-2 capsules before each meal [35]. This gives you a good starting point that you can increase if needed.
Adjusting based on your response
Finding the right enzyme dose depends on your meals and how your body reacts. These factors affect your ideal dose:
Meal size – bigger meals need more enzymes
- Fat content – fatty foods require extra lipase
- Individual digestive capacity – varies with health status
- Specific food sensitivities – might need targeted enzymes
Your symptoms tell you if your dose needs changing. Ongoing issues like steatorrhoea (oily stools), bloating or unexplained weight loss might mean you need more enzymes [33]. Try adding 25,000 units with each meal or snack if this happens [33].
Too many enzymes can cause constipation or bowel blockage [9]. Finding your perfect balance takes time and patience, but sticking to a routine helps you get the best results [6].
Potential Side Effects and Safety Considerations
Digestive enzyme supplements are safe for most people, but you should know about their side effects and safety aspects[30].
Common mild reactions
Constipation tops the list of side effects from digestive enzyme supplements [36]. The digestive system shows other common reactions that include:
- Abdominal pain or cramping
- Nausea
- Diarrhoea (happens less often than constipation)
Manufacturer-recommended doses usually cause mild side effects [37]. These reactions might signal that you need a different dosage or that your digestive system doesn’t respond well to this specific enzyme formula.
When to consult your doctor
You should get medical help right away if you notice any serious symptoms such as:
- Severe abdominal discomfort [10]
- Joint pain [10]
- Frequent or painful urination [10]
- Signs of allergic reaction: rash, itching/swelling (especially of face/tongue/throat), severe dizziness, or breathing problems [10]
Your doctor needs to evaluate ongoing digestive issues. Reach out to them if you notice these warning signs: abdominal pain, bloating, diarrhoea, fatigue, nausea, vomiting, unexplained weight loss, low red blood counts, or gastrointestinal bleeding [38].
Medication interactions to be aware of
Several medications can interact with digestive enzymes. Bromelain might affect blood-thinning medicines like aspirin, heparin, and warfarin [37]. Pancreatic enzymes could reduce how well your body absorbs certain iron salts [34].
Watch out for interactions with:
- Acarbose and miglitol [10]
- Antibiotics like amoxycillin and tetracycline [37]
- Blood pressure medications/ACE inhibitors [37]
- Chemotherapy drugs [37]
Some groups need extra caution. Pregnant or breastfeeding women should talk to their healthcare providers before taking digestive enzymes since research hasn’t proven their safety for these groups [37]. People allergic to enzyme sources (like pork products or fruit latex) should read supplement ingredients carefully [37].
Let your doctor and pharmacist know about all your medications and supplements to avoid harmful interactions [10].
Natural Sources of Digestive Enzymes in Food
Your gut health can benefit from digestive enzymes found naturally in many foods, not just supplements. Adding these whole foods to your daily meals provides a natural way to support your digestive wellness.
Enzyme-rich fruits and vegetables
Tropical fruits excel as natural sources of digestive enzymes. Pineapple’s bromelain breaks down proteins and helps tenderise tough meats [11]. Papaya contains papain that works like bromelain to digest proteins [11]. Mango’s amylases turn complex carbs into easily digestible sugars [11].
You’ll find helpful enzymes in these foods too:
- Avocados: Rich in lipase that helps digest fats [11]
- Bananas: Pack amylases and glucosidases to break down starches [11]
- Kiwifruit: Contains actinidin, a protein-digesting enzyme [11]
- Ginger: Produces zingibain that aids protein digestion [11]
Fermented foods with enzymatic activity
The fermentation process enriches foods with beneficial enzymes and introduces helpful probiotics. Kefir comes packed with lipases, proteases and lactases [11]. The fermentation process creates various digestive enzymes in sauerkraut [11].
Korean kimchi contains Bacillus bacteria that produce proteases, lipases and amylases [11]. Miso’s koji fungi create lactases, lipases, proteases and amylases to support digestion [11].
Raw honey stands out with its mix of diastase, amylase, invertase and protease enzymes [11].
Incorporating enzyme-boosting foods into meals
Heat destroys enzymes, so eating these foods raw or lightly cooked gives you maximum digestive benefits [39]. Fresh pineapple or papaya at the start of your meal helps kickstart protein digestion.
Fermented foods make great side dishes and follow traditional wisdom. Europeans served sauerkraut with meals, while Koreans pair kimchi with most dishes [12].
Smoothies with enzyme-rich fruits or raw honey as a sweetener make easy additions to your diet [2]. You can also add avocados to salads or fresh ginger to your cooking for extra enzyme support [2].
Conclusion
Digestive enzymes play a vital role in nutrient absorption and gut health. Supplements can help with specific digestive problems, but you need to choose and use them carefully.
Several factors determine if enzyme supplements will work for you. The right enzymes must match your digestive issues. You should take the correct dose at the right time to get the best results. Broad-spectrum formulas help many people, but some might need single-enzyme products that target specific food sensitivities.
Safety should be your top priority with digestive enzyme supplements. Keep track of your symptoms to adjust dosages properly. You also need to watch out for side effects and how these supplements might mix with medications. Raw or minimally processed whole foods are a great way to get natural enzymes.
Research on digestive enzymes keeps revealing new ways they support overall health. Anyone with ongoing digestive problems should talk to their healthcare provider before taking enzyme supplements. This ensures proper evaluation and treatment of symptoms. The right enzyme supplements, used correctly, can boost your nutrient absorption and digestive health.
