Lactase Enzyme: How It Helps with Lactose Intolerance Symptoms

Summary of Key Points

The lactase enzyme is a supplement designed to help individuals who have difficulty digesting lactose, the sugar found in milk and dairy products. It is commonly used to relieve symptoms of lactose intolerance, such as bloating, gas, and diarrhea. The lactase enzyme works by breaking down lactose in the digestive system, making it easier for the body to process. Always consult a healthcare provider before starting or adjusting your dosage of lactase supplements.

Always follow the instructions provided by your healthcare provider or the product label.

Adverse Reactions and Side Effects of Lactase Enzyme

While the lactase enzyme is generally well-tolerated, some individuals may experience side effects, including:

1. Stomach Cramps: Rare, mild abdominal discomfort.
2. Nausea: Rare, mild sensation of nausea.
3. Diarrhea: Rare, may occur if taken in excessive amounts.
4. Allergic Reactions: Very rare, but may include rash, itching, or swelling. Seek medical attention if you experience any signs of an allergic reaction.

If you experience side effects, contact your healthcare provider. If symptoms persist or worsen, schedule a telemedicine appointment with one of our providers for further evaluation.

Contraindications for Lactase Enzyme Use

A contraindication is a specific condition where a medication should not be used because it may cause harm. Before taking the lactase enzyme, it’s important to understand if there are any reasons to avoid this medication.

Allergy to Lactase Enzyme: If you have a known allergy to lactase or any ingredients in the lactase enzyme supplement, you should not take this medication. Allergic reactions may include rash, itching, swelling, or difficulty breathing.

Galactosemia: This rare genetic disorder prevents the body from processing galactose, a sugar found in milk. Since the lactase enzyme breaks down lactose into galactose and glucose, people with galactosemia should avoid this medication as it could worsen their condition.

Drug-to-Drug Interactions with Lactase Enzyme

While the lactase enzyme is generally considered safe with few known drug interactions, it’s important to inform your healthcare provider about all medications you are taking, including prescription drugs, over-the-counter medications, and supplements. Currently, there are no widely recognized drug interactions with the lactase enzyme, but it’s always a good idea to double-check with your healthcare provider.

Lactase Enzyme in Pregnancy

Is it safe to take lactase enzyme when pregnant?

Lactase enzyme is generally considered safe during pregnancy. As a natural enzyme that helps break down lactose, it functions within the digestive system and is not absorbed into the bloodstream, making it unlikely to affect your baby. However, as with any supplement or medication, it’s important to consult your healthcare provider before starting lactase enzyme during pregnancy. If you experience symptoms of lactose intolerance while pregnant, one of our telemedicine providers can assist you in determining the best course of action.

Lactase Enzyme while Breastfeeding

Is it safe to take lactase enzyme while breastfeeding?

Yes, lactase enzyme is considered safe while breastfeeding. Since it works locally in the digestive system and does not enter the bloodstream, it will not pass into breast milk. If you experience lactose intolerance while breastfeeding, lactase enzyme can help manage your symptoms without affecting your baby. However, it’s always a good idea to discuss any new supplements or medications with your healthcare provider.

Estimated Cost of Lactase Enzyme Supplements

The cost of lactase enzyme supplements can vary depending on the brand and where you purchase them. With a GoodRx coupon, a 30-day supply typically ranges from $10 to $20 without insurance. For the most accurate pricing, check with your local pharmacy or online retailers.

Possible Alternatives to Lactase Enzyme

If you experience lactose intolerance or other digestive issues, there are several alternative treatments and lifestyle changes that may help. It’s important to discuss these options with your healthcare provider before making any changes to your treatment plan. You can also schedule a telemedicine appointment with one of our providers to explore these alternatives in more detail.

Lactose Intolerance

In addition to lactase enzyme supplements, reducing or eliminating lactose-containing foods from your diet may provide relief. Many people find success by switching to lactose-free milk or plant-based alternatives such as almond or soy milk.

Gastrointestinal Discomfort, Bloating, Gas

Making dietary adjustments, such as avoiding foods that commonly cause gas (e.g., beans, carbonated drinks, or high-fiber foods), may help alleviate symptoms. Probiotics and other digestive enzymes may also offer relief.

Diarrhea

If lactose intolerance leads to diarrhea, reducing lactose intake and using lactase enzyme supplements can help. Staying hydrated and following a bland diet may also ease symptoms.

Abdominal Pain

Lactase enzyme can reduce abdominal pain caused by lactose intolerance. For other causes, such as irritable bowel syndrome (IBS), dietary changes like following a low-FODMAP diet may be beneficial.

Malabsorption Syndrome

If you have a condition that affects nutrient absorption, such as celiac disease or Crohn’s disease, it’s important to work with a healthcare provider to manage your diet and consider supplements that support digestion.

Irritable Bowel Syndrome (IBS)

While lactase enzyme may help if lactose intolerance is a trigger, other IBS treatments include dietary modifications, stress management, and medications prescribed by your healthcare provider.

Crohn’s Disease

Lactase enzyme may be helpful if lactose intolerance is present, but managing Crohn’s disease typically requires a comprehensive treatment plan, which may include medications, dietary changes, and sometimes surgery.

Celiac Disease

If you have celiac disease, avoiding gluten is essential. Lactase enzyme may help if you also have lactose intolerance, but the primary treatment for celiac disease is adhering to a strict gluten-free diet.

Recent Updates on Lactase Enzyme Research

Recent research on lactase enzyme has focused on improving its effectiveness in various forms, such as chewable tablets, capsules, and liquid drops. Studies are also exploring the potential benefits of combining lactase enzyme with other digestive enzymes to provide more comprehensive relief for individuals with multiple food intolerances. Additionally, ongoing research is examining the role of gut microbiota in lactose intolerance, with some studies suggesting that probiotics may enhance lactose digestion in certain individuals. As new findings emerge, it’s important to stay informed and discuss any new treatment options with your healthcare provider. If you have questions about the latest research or how it may apply to your condition, our telemedicine providers are available to guide you through your options.
