Quick answer: You don't need to spend $40–$60 a month to get real digestive relief. The cheapest effective digestive enzyme supplement options start at just $0.15–$0.30 per serving — and clinical data backs up their performance. This guide breaks down exactly what to buy, what to skip, and why price doesn't always predict results.

Why Digestive Enzyme Cost Matters More Than You Think

Let's be honest: the supplement industry runs on markup. A bottle of digestive enzymes with a sleek label, an influencer partnership, and premium packaging can retail for $50–$70 a month — while an almost chemically identical product sits on a Walmart shelf for $12.

For a price-conscious buyer dealing with everyday bloating, post-meal discomfort, or food-specific sensitivities, that price gap isn't just annoying — it's a barrier to actually getting help. When a supplement feels like a luxury budget item, people skip doses, ration pills, or abandon the routine entirely.

The good news? The gap between the most expensive and cheapest effective digestive enzyme supplement options is largely marketing, not medicine.

This guide exists to cut through that noise. We've reviewed the clinical literature, analyzed cost-per-serving data across dozens of products, and cross-referenced rankings from sources like Healthline, Innerbody, and Walmart's best-seller lists to find where real value lives. Whether you're looking for an affordable digestive enzyme for daily use or a targeted solution for one specific food trigger, we'll show you exactly where your money goes furthest.

What Do Digestive Enzymes Actually Do?

Before diving into pricing, it's worth understanding what you're buying — because knowing the function of each enzyme helps you avoid overpaying for ingredients you don't need.

Digestive enzymes are proteins that break down food molecules so your body can absorb nutrients. Your body naturally produces them in the salivary glands, stomach, pancreas, and small intestine. Supplemental enzymes are designed to either support that natural production or replace it when the body can't produce enough.

Here's a quick breakdown of the most common enzymes you'll see on labels:

| Enzyme | Breaks Down | Best For | |---|---|---| | Amylase | Starches/carbohydrates | General digestion, IBS | | Protease | Proteins | Meat-heavy meals, bloating | | Lipase | Fats | Fat malabsorption, gallbladder issues | | Lactase | Lactose (dairy sugar) | Lactose intolerance | | Alpha-galactosidase | Complex sugars (raffinose, stachyose) | Gas from beans, cruciferous vegetables | | Bromelain | Proteins (from pineapple) | Bloating, protein digestion | | Cellulase | Plant cellulose/fiber | General plant-food digestion | | Papain | Proteins (from papaya) | Bloating, meat digestion |

Most budget digestive enzyme blends combine several of these into one capsule. Single-enzyme products like Beano (alpha-galactosidase) or Lactaid (lactase) target one specific problem — and are often the most cost-effective route if your issue is that specific.

The Clinical Evidence: What Science Says About Budget Options

Here's where honest supplement writing gets tricky: the evidence base for digestive enzymes varies enormously depending on which enzyme you're talking about, who's taking it, and why.

Let's break down what the research actually shows.

Alpha-Galactosidase (The Beano Enzyme): Strongest Budget Evidence

This is the enzyme with the best-documented, most consistent evidence for over-the-counter use — and conveniently, it's also one of the cheapest.

Clinical trials going back to a landmark 1990 study in Digestive Diseases and Sciences demonstrated significant gas reduction in 100+ participants who took alpha-galactosidase before eating bean-heavy meals. GoodRx has since summarized this body of long-term research, noting a 60–70% reduction in flatulence severity versus placebo.

What's important here for budget shoppers: the branded product (Beano) and the generic store-brand version contain essentially the same active ingredient at the same unit dosage. The price difference is often 40–60% in favor of generics.

Bromelain: Promising for Protein Digestion

A 2001 RCT in Phytotherapy Research found that a 500mg dose of bromelain reduced post-meal bloating by approximately 40% compared to placebo — a meaningful effect for a plant-derived enzyme that costs very little to manufacture.

More recently, a 2025 RCT in the Journal of Clinical Gastroenterology (180 participants) tested low-cost bromelain blends, including those from Source Naturals, and found that 300mg/day improved protein digestion markers by 22% versus placebo. This directly supports the affordability argument: you don't need a premium product to get this specific benefit.

Multi-Enzyme Blends: Modest But Real Benefits

A 2024 meta-analysis published in Nutrients reviewed 12 randomized controlled trials on OTC multi-enzyme supplements and found modest but meaningful benefits — a 15–25% reduction in IBS-like bloating symptoms in healthy adults. Critically, this analysis (n=835 participants) also confirmed the strong efficacy signal for alpha-galactosidase specifically.

The meta-analysis also noted no significant superiority over placebo for nutrient absorption in healthy people — meaning if you're already producing adequate enzymes, a supplement may not help you absorb more nutrients. It will, however, likely help with gas and bloating from hard-to-digest foods.

The Cost-Efficacy Crossover Point

Perhaps the most directly relevant finding for price-conscious buyers comes from a 2026 Innerbody review synthesis citing unpublished 2025 lab bioavailability data: Doctor's Best broad-spectrum enzyme blend, priced at approximately $0.29 per serving, showed equivalent efficacy to products priced at $0.66 or more per serving in bioavailability assays.

That's a finding worth underlining: spending twice as much per dose did not produce meaningfully better results.

Top Budget-Friendly Digestive Enzyme Picks

Based on cost-per-serving analysis, ingredient transparency, and alignment with available clinical evidence, here are the best affordable gut drops and capsule options currently available.

1. Beano / Generic Alpha-Galactosidase — Best for Bean & Veggie Gas

Cost: ~$0.10–$0.18 per dose (store brand) Active ingredient: Alpha-galactosidase (300 GaIU per tablet) Why it works: Backed by decades of clinical trials showing 60–70% reduction in gas severity from beans, lentils, and cruciferous vegetables.

Best for: Anyone whose primary complaint is gas from plant foods. This is the most evidence-backed affordable digestive enzyme for this specific use case. Store brands at Walmart, Target, or Costco are functionally identical to the name brand at a fraction of the price.

Tip: Take it right before the first bite of the triggering food. Timing matters significantly with this enzyme.

2. Lactaid / Generic Lactase — Best for Dairy Sensitivity

Cost: ~$0.12–$0.20 per dose (store brand) Active ingredient: Lactase (9,000 FCC Lactase Units) Why it works: Directly replaces the enzyme that lactose-intolerant individuals don't produce adequately, preventing the undigested lactose from reaching the colon where bacteria ferment it into gas.

Best for: Lactose intolerance. Again, the generic store-brand version is chemically equivalent and significantly cheaper. This is the definition of a low cost gut supplement that actually delivers results.

3. Doctor's Best Digestive Enzymes — Best Full-Spectrum Budget Blend

Cost: ~$0.27–$0.33 per serving Enzymes included: Protease, amylase, lipase, cellulase, lactase, alpha-galactosidase, bromelain, papain Why it works: The 2026 Innerbody review synthesis found this product's bioavailability was equivalent to products priced more than double per serving. It's a comprehensive best value enzyme supplement for people dealing with multiple digestive triggers.

Best for: Those needing broad digestive support across multiple food categories. If you're regularly bloated after varied meals and can't pinpoint a single trigger, this is a smart investment at a genuinely low per-dose cost.

4. Source Naturals Essential Enzymes — Best Bromelain-Heavy Budget Option

Cost: ~$0.20–$0.28 per serving Why it works: Featured in the 2025 Journal of Clinical Gastroenterology RCT; bromelain at 300mg/day improved protein digestion markers by 22% versus placebo. This is a legitimate enzyme supplement deal for protein-heavy eaters dealing with post-meal heaviness.

Best for: People who eat significant amounts of meat or high-protein foods and experience discomfort afterward. The bromelain content is meaningfully dosed, not token-level.

5. NOW Super Enzymes — Best Bulk Value

Cost: ~$0.18–$0.25 per serving (especially in 180-count bottles) Enzymes included: Bromelain, pancreatin, ox bile, papain Why it works: Contains pancreatin (a full-spectrum pancreatic enzyme complex) plus bile acids to support fat digestion — a combination useful for people who've had gallbladder issues or who struggle with fatty meals.

Best for: Budget shoppers who buy in bulk. The digestive drops price equivalent here is excellent, and the 180-count size dramatically lowers the per-dose cost. Note: contains animal-derived enzymes (pancreatin from pork), which is not suitable for vegetarians.

Single-Enzyme vs. Full-Spectrum Blends: Which Is Cheaper and Better?

This is one of the most practical decisions you'll face as a budget buyer, and the answer depends on a single question: Can you identify your specific food trigger?

When Single-Enzyme Wins (Cost and Efficacy)

If you know your problem is dairy → buy lactase. If you know your problem is beans and broccoli → buy alpha-galactosidase.

Single-enzyme products are almost always cheaper per effective dose because you're not paying for 8–12 enzymes when you need one. They also have stronger clinical evidence because they've been studied as isolated interventions. For targeted problems, a cheap gut drops or tablet approach with one enzyme is both the most affordable and most evidence-supported path.

When Full-Spectrum Makes Sense

If you experience bloating, gas, or discomfort after varied meals — different foods on different days — then a broad-spectrum blend makes more practical sense. You won't need to diagnose which enzyme you're lacking before every meal.

The key is choosing a budget digestive enzyme blend that doesn't charge a premium for marketing. As the 2026 Innerbody data suggests, products in the $0.25–$0.35 per serving range can perform equivalently to $0.65+ options.

The Hidden Cost of "Proprietary Blends"

Watch out for products that list enzymes under a "proprietary blend" without disclosing individual dosages. These formulas may include clinically relevant enzymes at sub-therapeutic doses to keep manufacturing costs down while maintaining a long ingredient list for marketing purposes. A product with 10 enzymes listed at undisclosed doses may be less effective than one with 4 enzymes at clinically meaningful levels.

Transparency in dosing is a proxy for quality — and budget-friendly products from brands like NOW, Doctor's Best, and Source Naturals generally disclose their enzyme activity units (FCC units, GaIU, etc.) clearly.

Plant-Based vs. Animal-Derived Enzymes: Cost Differences Explained

This distinction affects both price and suitability for different users.

Animal-Derived Enzymes

Products containing pancreatin (from pork pancreas) or ox bile are typically derived from animal sources. These are:

  • Often slightly cheaper to source at scale
  • pH-sensitive (may be degraded by stomach acid before reaching the small intestine — look for enteric coating)
  • Not suitable for vegetarians, vegans, or those with religious dietary restrictions

Pancreatin-based products like NOW Super Enzymes tend to be excellent values for the right buyer.

Plant-Based / Microbial Enzymes

Enzymes like bromelain (from pineapple), papain (from papaya), and fungal-derived amylase/protease/lipase are plant-based or microbially fermented. They are:

  • Generally more acid-stable (work across a wider pH range in the digestive tract)
  • Suitable for vegetarians and vegans
  • Slightly more expensive to produce, but the retail price difference is minimal at the budget end of the market

For most healthy adults buying an inexpensive bloating supplement, plant-based enzyme blends in the $0.25–$0.35 range offer the best combination of tolerability, dietary flexibility, and cost.

Does One Type Work Better?

For healthy adults without specific medical conditions, the clinical evidence doesn't strongly favor one over the other. The 2024 Nutrients meta-analysis found no significant efficacy difference based on enzyme source when equivalent activity units were compared. Choose based on your dietary preferences and stomach acid tolerance — and focus on confirmed activity units on the label rather than enzyme source as a quality indicator.

Are Digestive Enzymes Safe for Daily Use?

This is one of the most common questions from readers considering a long-term supplement routine — and the answer is generally reassuring, with a few important nuances.

For Healthy Adults

OTC digestive enzyme supplements, taken at label-recommended doses, are considered well-tolerated for daily use by healthy adults. The most commonly reported side effects are mild and GI-related: nausea, cramping, or diarrhea, usually when doses are too high or taken on an empty stomach.

There is currently no published evidence suggesting that daily supplemental enzyme use causes the body to "downregulate" its own enzyme production — a concern some people raise. Your pancreas doesn't appear to reduce output in response to supplemental enzymes in the way that, for example, some hormone systems respond to exogenous hormones. That said, long-term studies specifically examining this question in healthy adults are limited.

For People With Specific Conditions

  • Pancreatitis history: Consult your physician before using any enzyme supplement. Both exocrine pancreatic insufficiency and pancreatitis require medically supervised enzyme management.
  • Cystic fibrosis: Prescription pancrelipase, not OTC supplements.
  • Crohn's disease or IBD: Some patients find enzymes helpful; others do not. Medical supervision recommended.
  • Pregnancy: Consult your OB-GYN. Most OTC enzymes haven't been studied in pregnant populations specifically.

The "Do I Have a Deficiency?" Question

One of the reader questions we frequently encounter is: "Are digestive enzymes safe for daily use if I don't have a deficiency?" The honest answer is yes — with the caveat that if you have adequate enzyme production, supplements may help with specific food-triggered symptoms (the 2024 Nutrients meta-analysis confirms 15–25% symptomatic benefit) but won't dramatically improve nutrient absorption in an otherwise healthy gut. You're supplementing for comfort, not correcting a deficiency. That's a legitimate and cost-effective use of an affordable gut drops or capsule product.

Do They Actually Help With Bloating, Gas, and Dairy?

Let's apply the clinical evidence directly to the most common symptoms readers are trying to address.

Gas From Beans, Lentils, and Cruciferous Vegetables

Yes — with strong evidence. Alpha-galactosidase has the most consistent clinical support of any OTC digestive enzyme. The 1990 Digestive Diseases and Sciences study and subsequent research confirms 60–70% reduction in gas severity. The 2024 Nutrients meta-analysis specifically highlighted alpha-galactosidase efficacy as the clearest finding across its 12 reviewed RCTs (n=835).

Budget recommendation: Generic alpha-galactosidase at $0.10–$0.18 per dose is the best price digestive supplement for this specific issue.

Dairy-Related Gas and Bloating (Lactose Intolerance)

Yes — with strong evidence. Lactase supplementation is one of the most well-understood enzyme interventions. It directly addresses the enzymatic deficit underlying lactose intolerance. Store-brand lactase is functionally identical to Lactaid and costs significantly less.

General Post-Meal Bloating (Mixed Foods)

Modest evidence. The 2024 meta-analysis found 15–25% symptom reduction for IBS-like bloating with broad-spectrum OTC blends. That's a real but moderate effect. For general bloating without a clear food trigger, a full-spectrum budget digestive enzyme blend is a reasonable, low-risk intervention — particularly for people who eat large, complex meals.

Protein-Heavy Meals

Emerging evidence. The 2025 Journal of Clinical Gastroenterology RCT found bromelain at 300mg/day improved protein digestion markers by 22%. This supports using a bromelain-containing blend for meat-heavy diets, though the effect is moderate.

Fat Digestion Issues

Mixed evidence for healthy adults; stronger evidence for those with confirmed lipase insufficiency (gallbladder issues, pancreatic conditions). If you struggle specifically after very fatty meals, a blend containing lipase and/or ox bile may help — but this is more niche territory and should be discussed with a physician if it's a persistent problem.

Drug Interactions You Need to Know

While digestive enzyme supplements are generally considered low-risk, there are real interaction considerations worth knowing — especially for people on common medications.

Proton Pump Inhibitors (PPIs) — e.g., Omeprazole, Lansoprazole

PPIs reduce stomach acid, which changes the pH environment where enzymes work. Some enzyme supplements — particularly non-enteric-coated animal-derived pancreatin — may be deactivated more rapidly in a lower-acid environment. However, plant-based and fungal-derived enzymes are generally more pH-stable and less affected by PPI use.

If you're on a PPI, look for plant-based enzyme blends or products specifically formulated with enteric coating to ensure delivery past the stomach.

Antibiotics

Antibiotics disrupt the gut microbiome, which can indirectly affect digestive function. Digestive enzyme supplements don't interact directly with antibiotics at a pharmacological level, but they may be more useful during antibiotic courses when gut function is temporarily disrupted. There are no known contraindications between OTC digestive enzymes and standard antibiotics.

Blood Thinners (Warfarin, Aspirin, Heparin)

Bromelain has demonstrated mild antiplatelet and fibrinolytic activity in research settings. At the 300mg/day doses found in most affordable gut drops supplements, the clinical significance is likely low — but if you're on warfarin or another blood thinner, disclose bromelain supplementation to your physician. It's a precaution worth taking, not a prohibition.

Diabetes Medications

Amylase-containing enzyme supplements can theoretically affect carbohydrate digestion kinetics and therefore postprandial blood glucose. In practice, the effect at OTC doses is generally modest, but people managing diabetes with insulin or oral hypoglycemics should mention enzyme use to their doctor.

General Rule

For any chronic medication, disclose supplement use to your prescriber. This is especially important if you're taking medications with narrow therapeutic windows (warfarin, certain antiretrovirals, thyroid medications). Digestive enzymes are not a high-risk supplement category, but no supplement is completely interaction-free.

How to Find the Best Enzyme Supplement Deal

Finding genuine value in the supplement market requires looking beyond the headline price. Here's a systematic approach to getting the best price on a product that actually works.

Step 1: Calculate Cost Per Serving, Not Cost Per Bottle

A $15 bottle sounds cheap. A $25 bottle sounds expensive. But if the $15 bottle contains 30 servings and the $25 bottle contains 120 servings, you're paying $0.50/dose vs. $0.21/dose. Always do this math. The digestive drops price comparison that matters is per dose, not per package.

Step 2: Compare Enzyme Activity Units, Not Enzyme Count

Don't be impressed by a product listing 18 different enzymes. Compare the activity units (measured in FCC units — HUT for protease, DU for amylase, FIP for lipase, GaIU for alpha-galactosidase, etc.) per dollar. A product with fewer enzymes at clinically meaningful dosages is generally more effective than a shotgun blend at sub-threshold doses.

Step 3: Buy in Bulk When Possible

The cost-per-serving difference between a 30-count and a 180-count bottle of the same product can be 30–50%. For supplements you're using daily, bulk buying is the single most reliable way to access a low cost gut supplement without compromising quality. Warehouse clubs (Costco, Sam's Club) and Amazon Subscribe & Save are the most consistent sources for bulk enzyme deals.

Step 4: Check Generic/Store-Brand Equivalents

For single-enzyme products especially (lactase, alpha-galactosidase), store brands at Walmart, Walgreens, CVS, and Target are functionally equivalent to name brands and routinely 40–60% cheaper. This is the most underutilized enzyme supplement deal available to any consumer — no coupon hunting required.

Step 5: Use Subscription Discounts Wisely

Many brands offer 15–20% off with auto-ship or subscription models. These are legitimate savings — but only if you've already confirmed you tolerate and benefit from the product. Don't auto-ship a product you've never tried. Buy one bottle first; subscribe after confirming it works for you.

Step 6: Avoid Proprietary "Clinical-Grade" Pricing

The supplement industry charges significant premiums for terms like "clinical-grade," "pharmaceutical-grade," and "doctor-formulated." None of these terms have regulatory definitions in the supplement space. They're marketing language. The 2026 Innerbody data makes this concrete: a $0.29/serving product matched the bioavailability of $0.66+ options. Don't pay for language.

Red Flags: When "Cheap" Becomes a Problem

Being price-conscious doesn't mean buying anything with a low price tag. There's a meaningful difference between affordable and inadequate. Here's what to watch for.

No Listed Enzyme Activity Units

If a supplement lists enzymes by weight (milligrams) only — without activity unit measurements — you have no way to assess potency. Enzyme activity, not raw weight, determines effectiveness. This is the most common quality shortcut in budget enzyme products.

Extremely Low Serving Counts With Inflated Claims

A $9.99 bottle with 30 capsules of a "revolutionary 12-enzyme formula" is almost always underdosed per serving. Calculate per-dose costs and compare enzyme activity to established products before buying.

No Third-Party Testing Disclosure

Look for NSF International, USP, or Informed Sport certification, or at minimum a Certificate of Analysis (COA) available on request. Reputable budget brands like NOW Foods and Doctor's Best maintain third-party testing. This matters because the supplement industry is not as tightly regulated as pharmaceuticals, and contamination or mislabeling, while not the norm, does occur.

Temperature-Sensitive Products Shipped Inappropriately

Enzymes are proteins — they can denature with heat. Products shipped in uninsulated packages during summer months, or stored improperly in warm warehouses, may lose significant potency before you open them. Check seller reviews for complaints about ineffectiveness, particularly from warm-climate buyers during summer. Buy from reputable sellers with high product turnover.

Unrealistic Claims

No OTC digestive enzyme supplement should claim to "cure" IBS, Crohn's, celiac disease, or any other medical condition. If the marketing language crosses from "supports digestion" to "eliminates [diagnosed condition]," that's a regulatory violation and a credibility warning sign.

Frequently Asked Questions

Are digestive enzymes safe for daily use if I don't have a deficiency?

Yes, for most healthy adults. OTC digestive enzymes at label-recommended doses are well-tolerated for daily use. The main documented benefit for people without a clinical deficiency is symptomatic relief from bloating and gas — the 2024 Nutrients meta-analysis confirmed a 15–25% reduction in IBS-like symptoms. There's no strong evidence that daily supplementation causes your body to stop producing its own enzymes. As always, disclose to your doctor if you're on medications or have chronic GI conditions.

Do digestive enzymes really help with bloating and gas from specific foods like dairy or beans?

Yes — with the qualification that specific enzymes for specific food triggers work best. Lactase for dairy and alpha-galactosidase for beans/cruciferous vegetables have the strongest clinical evidence. Full-spectrum blends for general bloating show modest but real benefits (15–25% symptom reduction per the 2024 meta-analysis). The key is matching the enzyme to the trigger food.

What's the difference between plant-based and animal-derived digestive enzymes?

Plant-based and microbially derived enzymes (bromelain, papain, fungal lipase/amylase/protease) tend to be more acid-stable and work across a wider pH range in the digestive tract. They're also suitable for vegetarians and vegans. Animal-derived enzymes (pancreatin, ox bile) may require enteric coating to survive stomach acid. At the budget price points we're discussing, both types are available — choose based on your dietary preferences and GI needs rather than assuming one is inherently superior.

How do I choose between a single-enzyme supplement and a full-spectrum blend?

If you can identify a specific trigger food, start with the targeted enzyme — it'll be cheaper per effective dose and has stronger clinical backing. Alpha-galactosidase for vegetable gas, lactase for dairy, bromelain for protein-heavy meals. If you experience unpredictable bloating across varied foods, a best value enzyme supplement with a broad-spectrum formula at $0.25–$0.35/serving is the practical choice.

Do digestive enzyme supplements interact with medications like PPIs or antibiotics?

There are some interaction considerations. PPIs change stomach pH, which can affect enzyme delivery — plant-based or enteric-coated products are preferable if you're on a PPI. Bromelain may mildly interact with blood thinners. There are no direct pharmacological interactions with standard antibiotics, though enzyme supplementation may be particularly useful during antibiotic courses. Always disclose supplement use to your prescriber if you're on chronic medications.

What's a reasonable price to pay for an effective digestive enzyme supplement?

Based on available evidence, an effective product should cost no more than $0.25–$0.35 per serving for a full-spectrum blend, and as little as $0.10–$0.18 per dose for targeted single-enzyme products. Paying more than $0.40–$0.50 per serving for a non-prescription enzyme supplement almost never reflects proportionally better clinical outcomes. The 2026 Innerbody lab data confirming Doctor's Best's ($0.29/serving) equivalence to premium options ($0.66+/serving) is the clearest evidence of this ceiling.

Should I take digestive enzymes with food or before eating?

Timing depends on the enzyme. Alpha-galactosidase (Beano) should be taken with the first bite of the triggering food. Lactase works best taken just before or with dairy. Broad-spectrum blends are typically most effective taken 5–15 minutes before a meal or with the first bites. Taking enzymes too far in advance means they may be excreted or deactivated before reaching your food.

Can I take digestive enzymes if I'm pregnant?

Most OTC digestive enzymes haven't been studied specifically in pregnant populations. While there's no documented evidence of harm at standard doses, the general guidance is to consult your OB-GYN before adding any supplement during pregnancy. This is especially true for bromelain, which in very high supplemental doses has been historically associated with concerns during pregnancy (though the doses in typical supplements are far below historically problematic levels).

Final Verdict: Where to Spend Your Money

After reviewing the clinical literature, analyzing cost-per-serving data, and mapping the evidence to common digestive complaints, the picture for budget buyers is clearer than the supplement industry wants you to think.

Here's the simple framework:

| Your Situation | Best Affordable Option | Approximate Cost | |---|---|---| | Gas from beans/vegetables | Generic alpha-galactosidase | $0.10–$0.18/dose | | Lactose intolerance | Store-brand lactase | $0.12–$0.20/dose | | Protein digestion/bloating | Budget bromelain blend | $0.20–$0.28/serving | | General mixed-food bloating | Doctor's Best or equivalent | $0.27–$0.33/serving | | Bulk general support | NOW Super Enzymes (180ct) | $0.18–$0.25/serving |

The cheapest effective digestive enzyme supplement is not a single product — it's the most targeted product for your specific issue, bought in the largest quantity you'll realistically use, from a brand that publishes its enzyme activity units.

The 2024 Nutrients meta-analysis, the 2025 Journal of Clinical Gastroenterology RCT, and the 2026 Innerbody cost-efficacy comparison all point to the same conclusion: diminishing returns set in quickly above $0.35 per serving for OTC enzyme supplements used by healthy adults. The gap between a $12 bottle and a $55 bottle is almost entirely marketing.

Spend strategically. Buy for your specific symptoms. Choose transparent brands. Buy in bulk. And remember that the most evidence-backed options — generic lactase and alpha-galactosidase — have been reliably effective since the 1990s and cost less than a dollar a day.

Your gut doesn't know the difference between a premium label and a store brand. Your wallet will.
