That feeling. The uncomfortable bloating that swells your stomach after a bowl of ice cream, or the embarrassing gas that seems to be an unavoidable side effect of a healthy bean burrito. It’s a familiar story for millions of people, turning enjoyable meals into sources of anxiety and discomfort. You might wonder if your digestive system is simply “sensitive,” or if there’s something more specific going on. Often, the answer lies with tiny, powerful proteins called digestive enzymes.
Our bodies are complex chemical factories, and digestion is one of the most critical processes. It relies on a specialized workforce of enzymes to break down the food we eat into nutrients our bodies can absorb and use for energy, growth, and cell repair. When this enzymatic workforce is understaffed for a specific task, it can lead to a cascade of digestive issues. But what if you could call in temporary help? That’s the role of digestive enzyme supplements like Lactaid and Beano, which offer targeted support to help your system handle specific foods that might otherwise cause trouble.

Understanding the Role of Digestive Enzymes
Think of your last meal. Whether it was a slice of pizza, a salad, or a piece of fruit, it was composed of large molecules—carbohydrates, proteins, and fats. Your body cannot absorb these molecules in their original form. The job of digestive enzymes is to act like molecular scissors, snipping these large molecules into smaller, absorbable units.
The process begins in your mouth, where amylase in your saliva starts breaking down carbohydrates. It continues in the stomach, where pepsin begins to tackle proteins. However, the pancreas is the true enzyme powerhouse, releasing a potent cocktail of amylase, protease, and lipase into the small intestine to handle the bulk of digestion.
- Amylase: Breaks down complex carbohydrates (starches) into simple sugars (like glucose).
- Protease: Breaks down proteins into amino acids.
- Lipase: Breaks down fats into fatty acids and glycerol.
Additionally, the lining of the small intestine produces other specific enzymes, such as lactase, which is designed to break down lactose, the sugar found in milk.
When your body doesn’t produce enough of a particular enzyme, it’s called an enzyme insufficiency. This means specific foods pass through your digestive tract without being properly broken down. When these undigested food particles reach the colon, the bacteria that live there begin to ferment them. This fermentation process is what produces the gas, bloating, abdominal pain, and sometimes diarrhea associated with food intolerances.
Lactose Intolerance: When Dairy Becomes a Problem
Lactose intolerance is one of the most common digestive issues worldwide, affecting a significant portion of the adult population. The condition arises from a deficiency of the lactase enzyme. While most infants produce ample lactase to digest breast milk, production can decrease significantly after weaning—a genetically programmed process known as lactase non-persistence.
Without enough lactase, the lactose from milk, cheese, yogurt, and other dairy products travels to the colon undigested, leading to the classic symptoms of:
- Bloating
- Gas
- Abdominal cramps
- Diarrhea
This is where a supplement like Lactaid becomes incredibly helpful. Lactaid products contain lactase, the very enzyme that is missing. By taking a Lactaid supplement with dairy-containing foods, you provide your body with the necessary tool to break down lactose before it can cause problems. The enzyme works directly on the food in your digestive system, effectively pre-digesting the lactose into glucose and galactose, two simple sugars that are easily absorbed.
The effectiveness of supplemental lactase is supported by scientific evidence. Clinical studies have consistently shown that taking lactase tablets can significantly reduce symptoms and decrease breath hydrogen levels (a key marker of malabsorption) in individuals with lactose intolerance after they consume dairy.
The Mystery of the Musical Fruit: Why Beans Cause Gas
Beans, along with other legumes, cruciferous vegetables (like broccoli and cabbage), and whole grains, are notorious for causing gas. This isn’t a sign that these foods are unhealthy—quite the opposite. They are packed with fiber, vitamins, and minerals. The issue lies in a specific type of complex carbohydrate they contain, known as oligosaccharides (specifically, raffinose and stachyose).
Humans lack the enzyme necessary to break down these particular oligosaccharides in the small intestine. As a result, they arrive in the colon intact, where they become a feast for gut bacteria. The resulting fermentation produces hydrogen, carbon dioxide, and methane gas, leading to flatulence and bloating.
Beano offers a direct solution to this problem. Its active ingredient is the enzyme alpha-galactosidase. This enzyme, derived from a food-grade mold, is capable of breaking down the problematic oligosaccharides into simpler, digestible sugars. By taking Beano right before or with the first bite of a meal containing these foods, the enzyme can get to work breaking down the complex carbs before they reach the colon. This prevents the fermentation process from ever starting, thereby preventing the gas and bloating.
Research has validated the efficacy of alpha-galactosidase. A landmark double-blind, crossover study published in the Journal of Family Practice found that Beano was effective in preventing gas and other gastrointestinal symptoms resulting from a high-fiber diet. Subsequent studies, including those in pediatric populations, have reinforced that alpha-galactosidase is a safe and effective way to manage gas-related symptoms.
Practical Solutions: How to Use Digestive Enzyme Supplements
If you suspect a specific food is causing your digestive distress, digestive enzyme supplements can be a game-changer. Here’s how to approach using them:
1. Identify Your Triggers: Keep a food diary for a week or two. Note what you eat and any symptoms you experience afterward. This can help you pinpoint whether your issues are linked to dairy, beans, or other foods.
2. Choose the Right Supplement:
- If dairy is the culprit, Lactaid or a generic lactase supplement is your best bet.
- If beans, legumes, or vegetables like broccoli and cauliflower are causing gas, try Beano or a supplement containing alpha-galactosidase.
3. Timing is Everything: These supplements must be taken with the food they are intended to digest. They are not effective if taken hours before or after a meal.
- Lactaid: Take it just before or with your first bite/sip of dairy.
- Beano: Take it with your first bite of the problematic food.
4. Start with the Recommended Dose: Follow the package instructions. You may need to adjust the dose based on the amount of trigger food you are eating.
5. Listen to Your Body: While these supplements are effective for many, they may not eliminate symptoms for everyone. The severity of enzyme deficiency varies, as does individual sensitivity.
It is also important to recognize that these over-the-counter supplements are not regulated by the FDA in the same way as prescription drugs. This means their potency and purity can vary between brands. Stick with reputable, well-known brands for better consistency.
A Balanced Approach to Digestive Wellness
As we’ve seen, digestive enzyme supplements like Lactaid and Beano are powerful tools for managing specific food intolerances. They offer a practical way to expand your diet and enjoy nutritious foods without the fear of uncomfortable digestive consequences. They work by directly addressing the root of the problem—an enzyme deficiency—providing a targeted and scientifically-backed solution.
However, they are not a cure-all for every digestive issue. Persistent or severe digestive problems, such as chronic pain, unexplained weight loss, or changes in bowel habits, warrant a conversation with a healthcare provider. These could be signs of an underlying medical condition that requires a different approach to diagnosis and treatment.
By understanding how your digestive system works and utilizing the right tools, you can take control of your digestive health and foster a better relationship with the food you eat. If you think a digestive enzyme supplement could be right for you, consider it a targeted intervention to help your body do its job more effectively, one meal at a time.

Frequently Asked Questions (FAQ)
Can I take Lactaid and Beano at the same time?
Yes, for some individuals, taking both supplements during the same meal can be beneficial. For example, if you are eating a food that contains both dairy and gas-producing vegetables, like a bean and cheese burrito, you could use both. Since they contain different enzymes (lactase and alpha-galactosidase) that target different types of carbohydrates, they do not interfere with each other. As always, it is wise to listen to your body and discuss any concerns with a healthcare provider.
Are there any side effects to using digestive enzyme supplements?
For most people, over-the-counter digestive enzyme supplements like Lactaid and Beano are considered safe with minimal side effects. However, some people might experience mild stomach upset. It is important to note that Beano contains an enzyme derived from a food-grade mold, so individuals with a known mold allergy should avoid it. Additionally, because these supplements are not strictly regulated by the FDA, the purity and concentration can vary. Starting with a low dose and choosing a reputable brand is a good practice.
When should I see a doctor for my digestive issues?
While supplements can manage common food intolerance symptoms, they are not a substitute for medical care. You should consult a physician or a qualified healthcare provider if you experience persistent or severe symptoms, such as chronic abdominal pain, unexplained weight loss, persistent diarrhea or constipation, or blood in your stool. These could be signs of a more serious underlying condition, like celiac disease, inflammatory bowel disease (IBD), or exocrine pancreatic insufficiency (EPI), which requires a proper medical diagnosis and treatment plan.
Can I get these digestive enzymes from food?
While some foods, like pineapple (bromelain) and papaya (papain), contain natural digestive enzymes, they are generally not a reliable source for managing specific deficiencies. For instance, there is no significant food source of lactase or alpha-galactosidase. The most effective way your body gets the enzymes it needs is by producing them itself. A balanced diet rich in whole foods supports your body’s natural enzyme production, but for specific intolerances, a targeted supplement like Lactaid or Beano is often the most practical and effective solution.
