What is the Lactase Enzyme and Why is it Important?
The lactase enzyme is a crucial digestive protein produced in the small intestine. Its primary role is to break down lactose, a sugar found in milk and dairy products, into two simpler sugars—glucose and galactose—that can be easily absorbed by the body. For those who are lactose intolerant, the body produces insufficient lactase, leading to symptoms such as bloating, diarrhea, and stomach cramps when consuming dairy.
Lactase supplements provide a convenient solution for managing lactose intolerance. These supplements contain the enzyme in a form that aids the digestion of lactose, allowing individuals to enjoy dairy products without discomfort.
Why Lactase Enzyme Supplements Matter
Living with lactose intolerance can be challenging, especially when dairy-based foods are a regular part of one’s diet. Lactase enzyme supplements not only improve digestive health but also support nutritional balance. Dairy products are rich in calcium, vitamin D, and other essential nutrients that may be missed when avoided. By using lactase supplements, individuals can enjoy dairy’s nutritional benefits without adverse effects.
How We Picked the Best Lactase Enzyme Supplements
Choosing the best lactase enzyme supplements requires careful consideration of several factors to ensure effectiveness, safety, and value. Here’s how we evaluated our top picks:
1. Enzyme Potency
The effectiveness of a lactase supplement largely depends on its enzyme activity level, typically measured in FCC (Food Chemical Codex) units. We prioritized supplements with higher FCC units to ensure they could break down larger amounts of lactose.
2. Formulation and Ingredients
Purity matters. We favored supplements free from unnecessary fillers, artificial colors, and allergens. Additionally, we assessed whether the formulations included other digestive enzymes or probiotics to provide added digestive support.
3. Ease of Use
Lactase supplements come in various forms, including tablets, capsules, chewables, and liquid drops. We selected options that were convenient to use and tailored to diverse lifestyles, such as on-the-go solutions and kid-friendly formulations.
4. Clinical Testing and Safety
Products with third-party testing for potency and purity received higher rankings. We also checked for certifications such as NSF, GMP (Good Manufacturing Practices), and FDA compliance to ensure the supplements met rigorous safety standards.
5. Customer Reviews and Ratings
User feedback provides valuable insights into a product’s real-world performance. We analyzed reviews to gauge customer satisfaction, focusing on consistency in effectiveness and minimal reports of side effects.
6. Cost-Effectiveness
While premium supplements often come at a higher price, we considered affordability and the value provided per dose, ensuring that our recommendations cater to various budgets.

Whether you’re chasing maximum strength, clean ingredients, or value for money, this list has something for every dairy-loving soul.
Let’s find out the best option for you.
1. LactoJoy Lactase Tablets
If simplicity is your thing, LactoJoy Lactase Tablets are a top contender. Made with 14,500 FCC units of lactase per tablet, this supplement is potent enough to tackle even the cheesiest pizza nights. The vegan-friendly formula is free of unnecessary fillers, making it ideal for those who prefer a clean-label option.
Why It’s Our Top Pick
The standout feature? Portability. These come in a cute, pocket-sized metal case perfect for those who are always on the go. Compared to other brands, LactoJoy’s minimalistic ingredient list is a major win for health-conscious users. Plus, it starts working quickly, so no waiting around while your ice cream melts!
Pros:

- Clean, vegan-friendly formula.
- Compact, travel-friendly case.
Cons:
- Premium price point.
- Tablets can be hard to split for smaller doses.
How It Compares
Unlike larger tablets like Lactaid Ultra (coming up), LactoJoy’s sleek design makes it incredibly convenient. It’s perfect for anyone who values both potency and style.
2. Lactaid Fast Act Chewables
With decades of brand recognition, Lactaid is practically synonymous with lactase supplements. Their Fast Act Chewables pack a punch with 9,000 FCC units per tablet and a pleasant vanilla flavor.
Why It Ranks High
These chewables dissolve quickly, which means they work fast—ideal for spontaneous dairy indulgences. While not as potent as LactoJoy, the chewable format makes it easier for kids and adults alike to take on the spot.
Pros:
- Quick-acting formula.
- Tasty vanilla flavor.
- Trusted brand with decades of expertise.
Cons:
- Contains artificial sweeteners.
- Lower potency compared to some other options.
How It Compares
Compared to LactoJoy, Lactaid Fast Act is more budget-friendly but slightly less potent. However, its chewable format makes it a favorite for those who dislike swallowing tablets.
3. Now Foods Dairy Digest Complete
Now Foods Dairy Digest Complete goes beyond just lactase. It combines three enzymes—lactase, protease, and lipase—to help digest not only lactose but also proteins and fats in dairy.
Why It Stands Out
This supplement is ideal for those who experience bloating or other discomfort beyond lactose intolerance. With a broader enzyme profile, it’s a multitasker for overall dairy digestion.
Pros:
- Comprehensive enzyme blend.
- Affordable price point.
- Free of GMOs and artificial ingredients.
Cons:
- Lower lactase potency (1,000 FCC units/capsule).
- Requires multiple capsules for larger meals.
How It Compares
While it lacks the single-focus punch of LactoJoy, Now Foods Dairy Digest Complete shines for people with general dairy sensitivity. It’s less potent but covers more bases.
4. Enzymedica Lacto
When you need industrial-strength support, Enzymedica Lacto delivers. Each capsule contains 9,000 FCC units of lactase and a blend of additional enzymes for tackling even the heaviest dairy meals.
Why It’s Worth a Look
The proprietary Thera-blend process ensures the enzymes stay active across various pH levels, making it effective throughout your digestive tract.
Pros:

- High potency.
- Backed by Thera-blend technology for better efficacy.
Cons:
- Higher price point.

5. Digestive Advantage Lactose Defense Formula
If you’re someone who values simplicity but wants an extra edge, Digestive Advantage Lactose Defense Formula combines lactase with BC30 probiotics. This dual-action formula doesn’t just break down lactose—it also promotes long-term gut health.
Why It’s a Smart Choice
Probiotics like BC30 are scientifically proven to support digestion and reduce bloating. According to a study published in the Journal of Clinical Gastroenterology, BC30 is highly resilient and survives stomach acid to reach the intestines, where it does its magic.
Pros:
- Includes probiotics for added gut health benefits.
- Easy-to-swallow capsules.
- Affordable and widely available.
Cons:
- Only 3,000 FCC units of lactase per capsule.
- Effects may take longer due to probiotic integration.
How It Compares
While less potent than LactoJoy or Enzymedica Lacto, Digestive Advantage offers long-term benefits through probiotics, which set it apart. This is a great choice for people who want a “two-in-one” solution.
6. Kirkland Signature Fast Acting Lactase
Costco fans, rejoice! Kirkland Signature Fast Acting Lactase delivers great value without skimping on effectiveness. Each caplet contains 9,000 FCC units of lactase, making it perfect for heavy dairy meals.
Why It Stands Out
This budget-friendly option proves you don’t have to break the bank for reliable results. Its simple formula gets straight to the point without any bells or whistles.
Pros:
- Affordable price for a large quantity.
- High potency (9,000 FCC units/caplet).
- Trusted brand with consistent quality.
Cons:
- Basic formula with no additional enzymes or probiotics.
- Caplets may be too large for some to swallow comfortably.
How It Compares
Kirkland Signature competes directly with Lactaid Fast Act but wins on price. However, it lacks the chewable option and portability of Lactaid.
7. Best Naturals Lactase Enzyme
For those who want a supplement that’s gentle yet effective, Best Naturals Lactase Enzyme is a worthy option. Each tablet provides 9,000 FCC units of lactase in a gluten-free, non-GMO formula.

This supplement is all about the essentials, with no artificial additives or unnecessary extras. It’s especially appealing to those with additional dietary restrictions.
Pros:
- Gluten-free and non-GMO.
- High potency per tablet.
- Affordable pricing.
Cons:
- No additional enzymes for broader digestion.
- Tablets are slightly chalky in texture.
How It Compares
