Cellulase Enzyme Supplement For Gas And Bloating Clean Label

---

Quick answer: Cellulase is a plant-fiber-digesting enzyme that may reduce gas and bloating caused by undigested cellulose from vegetables, beans, and whole grains. Clinical evidence for cellulase alone is limited, but it appears in many well-regarded digestive enzyme blends. If you're buying, prioritize a clean label cellulase supplement — no fillers, non-GMO, vegan capsules or drops — and look for formulas that pair cellulase with alpha-galactosidase, amylase, and protease for broader relief.

What Is Cellulase and Why Does It Matter for Gas?

If you've ever eaten a big salad, a bowl of roasted vegetables, or a plate of beans and spent the next two hours feeling like a slowly inflating balloon, the culprit is almost always undigested plant fiber — specifically cellulose, hemicellulose, and related polysaccharides that form the structural walls of every plant cell you eat.

Humans do not naturally produce cellulase. That single fact explains a massive amount of digestive discomfort.

Cellulase is an enzyme that breaks the beta-1,4-glycosidic bonds in cellulose — essentially cutting long, rigid chains of glucose into smaller, manageable fragments that your small intestine can either absorb or pass to the large intestine in a form that doesn't feed explosive gas-producing bacteria nearly as aggressively.

When you take cellulase for gas, you're supplementing an enzymatic gap that is hard-wired into human physiology. Cows, horses, and termites carry gut microbes that produce cellulase constantly. Humans largely don't — and the modern high-fiber, plant-forward diet is making that gap more uncomfortable than ever.

The Fiber Fermentation Chain

Here's the chain of events that leads to gas and bloating after a high-fiber meal:

1. You eat vegetables, legumes, or whole grains. Every cell wall contains cellulose.
2. Cellulose reaches the large intestine mostly intact because human digestive enzymes don't break it down.
3. Gut bacteria ferment it. The byproducts are hydrogen, methane, carbon dioxide — gas.
4. Gas accumulates faster than it can be expelled, creating pressure, distension, and that familiar tight, uncomfortable feeling.

Supplemental cellulase for bloating intervenes at step 2, reducing how much intact cellulose arrives in the colon in the first place.

How Cellulase Targets Fiber-Related Bloating

Understanding where cellulase works helps you set realistic expectations — and helps you decide whether cellulase alone is what you need or whether you need a broader formula.

Cellulase Plant Fiber Digestion: The Mechanism

Cellulase plant fiber digestion begins in the small intestine, where supplemental enzymes work alongside your pancreatic enzymes. When you swallow a cellulase supplement with your first bite of food, the enzyme travels into the stomach (relatively acid-stable, depending on the source organism), passes into the duodenum, and begins cleaving cellulose chains throughout the small intestine's transit time.

The result: smaller oligosaccharide fragments rather than long-chain cellulose polymers arriving at the colon. Less fermentation substrate means less gas production.

Cellulase for vegetable digestion is particularly relevant for:

• Cruciferous vegetables (broccoli, cauliflower, Brussels sprouts, cabbage) — notoriously high in both cellulose and glucosinolates
• Root vegetables (carrots, parsnips, sweet potato) — dense cell-wall content
• Leafy greens (kale, spinach, chard) — high oxalate + cellulose combination
• Legumes (beans, lentils, chickpeas) — cellulose plus oligosaccharides like raffinose

Important nuance: Legume gas is driven primarily by alpha-galactosides (raffinose, stachyose), which require alpha-galactosidase (the enzyme in Beano) to break down — not cellulase. Cellulase handles the cell-wall component of legume digestion, not the oligosaccharide component. For legume-specific gas, you need both.

Cellulase for Fiber Intolerance

Some individuals experience what amounts to a fiber intolerance — not a formal medical diagnosis, but a real functional pattern where high-fiber foods consistently produce disproportionate gas, bloating, or loose stools. These people tend to respond most noticeably to cellulase supplementation because their colonic fermentation load is chronically high.

Cellulase for fiber intolerance is not a cure — it's an ongoing enzymatic support tool. Think of it the way lactase works for lactose intolerance: you don't "fix" the problem, you manage it meal by meal.

What the Clinical Evidence Actually Says

Let's be direct here, because too many supplement blogs aren't.

The Honest Evidence Summary (2024–2026)

Direct human clinical evidence for cellulase alone is very limited. Current evidence summaries published through 2026 state that randomized controlled trial (RCT) evidence for cellulase as a standalone intervention is essentially absent. The studies that do show positive outcomes — symptom-score reductions of approximately 20–40% in limited samples — come from open-label trials, small product studies, or multi-enzyme blend formulations where cellulase is one of several active ingredients. Isolating cellulase's specific contribution in those blends is methodologically difficult.

This is not a reason to dismiss cellulase. It is a reason to:

1. Understand that marketing claims often outpace the science for any single digestive enzyme
2. Look at mechanistic plausibility — the enzyme does what it's supposed to do biochemically; the clinical gap is an evidence problem, not a mechanism problem
3. Choose products that don't oversell the evidence — which, incidentally, is a core marker of a genuinely transparent cellulase supplement

What the Research Does Support

• Cellulase is biochemically active in the human GI tract under appropriate pH conditions
• Multi-enzyme blends containing cellulase alongside amylase, protease, lipase, and alpha-galactosidase show consistent subjective improvement in gas and bloating symptoms in available studies — with the caveat that the relative contribution of each enzyme is unclear
• Products like Enzymedica Digest Gold, SFI Health/Klaire Labs Digestive Enzymes, and similar blends have been studied or documented for symptom reduction in digestive comfort outcomes
• The 2024–2026 product landscape shows strong continued market validation — not clinical proof, but meaningful real-world signal — with cellulase-containing blends remaining among the top-selling digestive enzyme categories

What to Tell Your Doctor

If you're managing a diagnosed GI condition (IBS, SIBO, IBD, celiac disease), discuss digestive enzyme use with your healthcare provider before starting. Cellulase supplementation is generally considered low-risk, but it's not a substitute for medical diagnosis or treatment.

Clean Label: Why It Matters More Than the Brand Name

"Clean label" isn't just a marketing buzzword — for digestive enzyme supplements specifically, it's a functional quality signal. Here's why.

The Filler Problem in Enzyme Supplements

Many digestive enzyme capsules are filled with excipients that can actively worsen bloating in sensitive individuals:

• Magnesium stearate — a flow agent used in tablet and capsule manufacturing; generally regarded as safe but unnecessary
• Silicon dioxide — an anti-caking agent; similarly benign but avoidable
• Maltodextrin — a cheap filler with a high glycemic index; can feed dysbiotic bacteria in the gut
• Titanium dioxide — a whitening agent with emerging safety concerns in EU regulations
• Artificial colors and coatings — no digestive function, potential reactivity in sensitive individuals
• Microcrystalline cellulose (MCC) — ironic in a cellulase supplement: you're taking an enzyme to break down cellulose while swallowing indigestible cellulose as a filler

A no filler cellulase supplement contains the active enzyme, a clean capsule (typically HPMC or pullulan for vegan formulations), and nothing else — or minimal, clearly disclosed additions like organic rice flour or ascorbic acid as a natural preservative.

What "Clean Ingredient Cellulase" Actually Means on a Label

When evaluating a clean ingredient cellulase product, look for:

| ✅ Acceptable "Other Ingredients" | ❌ Red Flag Ingredients | |---|---| | HPMC (vegetarian capsule) | Magnesium stearate | | Pullulan (vegan capsule) | Titanium dioxide | | Organic rice flour | Maltodextrin | | Ascorbic acid (as preservative) | Artificial colors (FD&C) | | Microcrystalline cellulose (minimal, disclosed) | Sodium benzoate | | Nothing (enzyme only) | Hydrogenated oils |

Non-GMO Cellulase: Does It Matter?

Non-GMO cellulase supplement labeling reflects both production and sourcing standards. Most commercial cellulase is produced by fermentation using Trichoderma reesei or Aspergillus niger — fungal organisms that may be genetically modified in industrial settings to improve yield.

A non-GMO cellulase supplement uses fungal strains that have not been genetically engineered, verified through third-party non-GMO project certification or equivalent auditing. For consumers who prioritize non-GMO sourcing, this distinction matters — and it's often linked to other quality commitments (organic, allergen-free, third-party tested).

The Transparency Dimension

A transparent cellulase supplement brand does several things that separate it from average supplement companies:

1. Discloses enzyme activity units (CU — Cellulase Units — on the label), not just milligrams
2. Names the fungal source of the cellulase
3. Publishes third-party testing certificates (COA — Certificate of Analysis) on their website
4. Clearly lists every "other ingredient" rather than hiding excipients in a footnote
5. Doesn't make unsupported disease claims — a company that tells you cellulase "cures" IBS or "eliminates" bloating permanently is not a trustworthy source

A cellulase supplement no additives approach — where the only thing in the bottle is the enzyme and a clean capsule — is the gold standard for this category.

Cellulase Enzyme Drops vs. Capsules: Which Format Wins?

Cellulase enzyme drops are a growing segment of the market, and they have genuine advantages over capsules in specific situations.

The Case for Cellulase Enzyme Drops

Liquid drops offer:

• Faster onset — no capsule dissolution time; enzyme is bioavailable immediately on contact with food
• Dosing flexibility — you can add drops directly to a meal, smoothie, or soup, or adjust drops per serving based on the fiber content of a specific dish
• No capsule materials — eliminates even clean capsule components; suitable for individuals with sensitivities to all capsule materials
• Pediatric/elderly use — swallowing difficulties make drops preferable for some populations
• Compatibility with cooking — some drops can be added to warm (not hot) foods, though enzyme activity degrades above approximately 60°C/140°F

The best clean cellulase drops products use:

• Vegetable glycerin as a base (vs. propylene glycol — avoid)
• Purified water
• Natural preservation (citric acid, rosemary extract)
• No artificial sweeteners or flavors

The Case for Capsules

Capsules remain the dominant format because:

• Delayed release options (enteric coating or acid-resistant capsules) protect enzymes through stomach acid, potentially improving delivery to the small intestine
• Combination formulas are easier to standardize in capsule form — you can pack cellulase alongside 8–10 other enzymes in precise ratios
• Shelf stability is generally better in dry powder capsules vs. liquid drops
• Portability — easier to travel with; no spill risk

For most buyers, a clean capsule formula in a full-spectrum enzyme blend is the practical choice. Cellulase enzyme drops are the better pick for individuals who prefer liquid supplements, have difficulty swallowing, want to add enzymes directly to specific high-fiber meals, or are buying for a child or elderly family member.

How to Read a Cellulase Supplement Label

Most people look at the front of a supplement bottle and buy based on the marketing copy. Here's how to flip it over and actually evaluate what you're getting.

Enzyme Activity Units vs. Milligrams

This is the most important concept on a cellulase supplement label.

Milligrams (mg) tell you nothing about enzyme activity. A milligram of highly active cellulase is worth far more than a milligram of poorly concentrated material. The relevant measurement is CU (Cellulase Units) — a standardized activity measurement defined by the Food Chemical Codex (FCC).

Typical cellulase doses in commercial digestive enzyme blends range from 500 CU to 4,000 CU per serving. Standalone or higher-potency formulas may reach 10,000 CU or more.

A label that only shows milligrams and not CU is either:

1. Using a non-standard measurement system (some brands use their own unit names)
2. Obscuring the actual activity level of the enzyme

Ask for or look for CU on the label. If it's not there, contact the manufacturer before buying.

Sample Label Anatomy

` Supplement Facts Serving Size: 1 Capsule

Amount Per Serving % DV Cellulase (from Aspergillus niger) 2,000 CU * Amylase (from Aspergillus oryzae) 5,000 DU * Alpha-Galactosidase (from A. niger) 150 GalU *

Other Ingredients: Hydroxypropyl methylcellulose (capsule)

• Daily Value not established.

`

This is what a clean, transparent label looks like. Compare it to a label that says:

` Proprietary Digestive Enzyme Blend 250 mg [cellulase, amylase, protease, lipase, lactase...]

Other Ingredients: Gelatin, magnesium stearate, silicon dioxide, maltodextrin, FD&C Blue No. 1 `

The second label hides enzyme amounts in a proprietary blend and loads the formula with unnecessary additives. Pass.

Certifications to Look For

• Non-GMO Project Verified — third-party non-GMO verification
• NSF Certified or USP Verified — independent quality testing
• Certified Vegan — confirms no animal-derived ingredients including capsule material
• Gluten-Free Certified — important for celiac or gluten-sensitive buyers
• USDA Organic — covers the fungal fermentation substrate and other ingredients
• Kosher/Halal — relevant for specific dietary requirements

Cellulase Alone or in a Blend? The Honest Answer

This is the question most buyers are wrestling with when they research cellulase for gas and don't know whether to buy a standalone product or a full-spectrum digestive enzyme formula.

The Short Answer

For most people with gas and bloating from a mixed diet, a multi-enzyme blend that prominently features cellulase will outperform cellulase alone.

Why Blends Work Better for General Bloating

Gas and bloating after meals typically have multiple simultaneous causes:

| Source | Enzyme Needed | |---|---| | Cellulose from vegetable cell walls | Cellulase | | Starch from grains, potatoes | Amylase | | Proteins from meat, legumes, dairy | Protease | | Fats (delayed gastric emptying) | Lipase | | Lactose from dairy | Lactase | | Raffinose/stachyose from beans | Alpha-galactosidase | | Hemicellulose from plant fiber | Hemicellulase | | Phytic acid from grains/seeds | Phytase |

If you eat a varied diet — as most people do — a single enzyme only addresses one of these fermentation pathways. A well-formulated blend addresses all of them simultaneously.

When Cellulase Alone Makes Sense

A standalone cellulase product makes sense if:

• You've identified through an elimination diet that your gas is specifically triggered by cellulose-rich vegetables and high-fiber plant foods, not dairy, starch, or legumes
• You're already taking separate enzymes for other triggers and want to add cellulase specifically
• Your healthcare provider or registered dietitian has specifically recommended isolated cellulase
• You're using cellulase enzyme drops in cooking applications where you need a single-enzyme product

The Best of Both Worlds

Look for a clean-label multi-enzyme formula that leads with cellulase in meaningful activity units (not just a token 100 CU in a long proprietary blend), includes alpha-galactosidase for legumes, lactase if you eat dairy, amylase for starches, and protease for protein digestion — all in disclosed, non-proprietary amounts, in a clean capsule with no unnecessary fillers.

That's the profile of the best clean cellulase drops or capsule formula for most buyers.

Dosage, Timing, and How Fast It Works

Recommended Dosage Ranges

| Product Type | Typical Cellulase Dose | Context | |---|---|---| | Standalone cellulase capsule | 2,000–10,000 CU | High-fiber meal support | | Multi-enzyme blend capsule | 500–4,000 CU | Everyday digestive support | | Cellulase enzyme drops | 1–3 drops per meal | Flexible dosing | | High-potency therapeutic blend | 5,000–20,000 CU | Practitioner-directed |

These are general ranges. Always follow the specific product label.

Timing: Before, With, or After Meals?

Take cellulase with your first bite of food. This is the optimal timing for all digestive enzymes.

Here's why: Enzymes need to be in the digestive tract simultaneously with the food substrate they're meant to act on. If you take cellulase 30 minutes before eating, it may pass through the stomach before your meal arrives. If you take it at the end of a meal, you've missed the early small intestine window where enzyme activity is most productive.

Practical rule: Keep your cellulase supplement at the table, next to the salt and pepper. Take it when you sit down to eat.

How Fast Does Cellulase Work?

Digestive enzyme effects are typically felt — or not felt — within 1–3 hours after a meal, which is the timeframe when post-meal gas and bloating typically peak. Many users report noticeably less bloating and distension in the 2–4 hours following high-fiber meals when taking cellulase-containing enzyme formulas.

Cellulase does not provide immediate relief for gas that's already trapped in the colon — that's a job for simethicone or activated charcoal products. Cellulase is preventive, not rescue.

For best results:

• Take consistently with every high-fiber meal, not sporadically
• Allow 2–4 weeks of consistent use to notice baseline changes in typical bloating patterns
• Track symptom patterns — a simple bloating diary (1–10 scale after each meal) is surprisingly revealing

---

Who Benefits Most From Cellulase Supplementation?

Strong Candidates for Cellulase Supplementation

1. Plant-based and vegan eaters Every meal is high in plant fiber. Cellulase is essentially a standard supplement for this population.

2. People transitioning to higher-fiber diets When people increase vegetable, whole grain, or legume intake — whether for health goals, dietary change, or weight management — their gut microbiome hasn't yet adapted to the fermentation load. Cellulase can bridge that transition period.

3. Individuals with cellulase for fiber intolerance patterns People who consistently react to vegetables, salads, or whole grains with disproportionate gas and bloating — even when dairy and gluten have been ruled out — are good candidates.

4. Older adults Pancreatic enzyme output naturally declines with age, and digestive enzyme supplementation broadly becomes more beneficial after age 50.

5. People with low stomach acid (hypochlorhydria) Low gastric acid reduces the activation of digestive enzymes throughout the GI tract, making supplementation more impactful.

Cellulase Is Likely Less Relevant For:

• Gas and bloating primarily triggered by dairy → lactase is the priority
• Gas from beans and legumes specifically → alpha-galactosidase is the priority
• Gas from carbonated beverages → no enzyme solution; simethicone if needed
• SIBO (Small Intestinal Bacterial Overgrowth) → requires medical treatment; enzyme supplements alone won't resolve SIBO

Red Flags: What to Avoid When You Buy

When you're ready to buy clean cellulase supplement products, these are the warning signs that should send you to a different brand.

🚩 Red Flag #1: Proprietary Blend Hiding Cellulase

If the label says "Digestive Enzyme Blend — 300 mg" followed by a list of 12 enzymes including cellulase, you have no idea how much cellulase is actually in there. It could be 5 CU. Transparency means disclosed amounts.

🚩 Red Flag #2: No Activity Units Listed

If the label shows milligrams but no CU (Cellulase Units), the company is either uninformed about enzyme labeling standards or deliberately obscuring potency. Either reason is disqualifying.

🚩 Red Flag #3: Long "Other Ingredients" List

A cellulase supplement no additives product should have a very short "Other Ingredients" section. If you see 6+ fillers, flows agents, coatings, or colors, the manufacturer prioritized production cost over product quality.

🚩 Red Flag #4: Overclaiming

Phrases like "eliminates bloating permanently," "cures digestive issues," or "clinically proven to resolve IBS" are either regulatory violations (for supplement claims) or misleading exaggeration. Trustworthy brands use language like "supports healthy digestion" and "may help reduce occasional gas and bloating."

🚩 Red Flag #5: No Third-Party Testing

Any supplement brand that cannot point you to a Certificate of Analysis (COA) from an independent testing laboratory is asking you to trust them on their word alone. Third-party testing verifies potency, purity, and absence of contaminants.

🚩 Red Flag #6: Suspiciously Low Price

High-quality, clean-label, non-GMO, third-party tested cellulase enzyme products have real production costs. A 60-capsule bottle priced at $6.99 is almost certainly not using quality-certified enzymes, clean excipients, or paying for independent testing.

Frequently Asked Questions

Does cellulase actually help with gas and bloating, or is it mainly marketing?

Both, depending on the brand. Mechanistically, cellulase is a real enzyme that genuinely breaks down cellulose — the primary structural component of plant cell walls — and reducing intact cellulose arriving in the colon does meaningfully reduce fermentation substrate and subsequent gas production. The biochemistry is sound. Clinically, isolated cellulase has very little RCT evidence, and most of the positive outcome data comes from multi-enzyme blends. So: the mechanism is real, the clinical proof is weak, and the marketing often oversells the evidence. Honest answer: it's worth trying for fiber-related bloating specifically, especially in a quality multi-enzyme formula, with realistic expectations.

Is cellulase better for bean/legume gas, fiber-related bloating, or general indigestion?

Fiber-related bloating from vegetables is where cellulase is most directly relevant. For bean and legume gas, alpha-galactosidase (Beano's active ingredient) is more targeted because legume gas is primarily driven by oligosaccharides (raffinose, stachyose), not cellulose. For general indigestion across protein, fat, starch, and dairy, you need a full-spectrum enzyme blend.

What dose of cellulase is used in digestive enzyme blends?

Typical doses range from 500–4,000 CU in multi-enzyme blends and up to 10,000 CU or more in high-potency standalone products. Look for CU (Cellulase Units) on the label, not milligrams.

Are clean label, vegan, gluten-free, or GMO-free cellulase supplements more effective?

Not inherently more effective at the enzyme level — a non-GMO cellulase molecule doesn't break down cellulose faster than a conventional one. However, clean label and non-GMO cellulase supplement products are less likely to contain fillers that cause their own digestive irritation in sensitive individuals. For buyers with reactive digestive systems, the absence of unnecessary additives can make a real difference in tolerability and attributable outcomes.

Is cellulase alone enough, or should it be combined with alpha-galactosidase, lactase, protease, and lipase?

For most people eating a varied diet, a multi-enzyme blend is more effective than cellulase alone. Cellulase alone is appropriate only if you've specifically identified cellulose-rich vegetables as your sole trigger. For comprehensive meal-time digestive support, look for a formula pairing cellulase with alpha-galactosidase, amylase, protease, lipase, and lactase at minimum.

How fast does cellulase work, and should it be taken before meals or with the first bite?

Take it with the first bite of food — this is optimal timing for all digestive enzymes. Effects are noticed in the 1–3 hour post-meal window when gas and bloating typically peak. Cellulase is preventive, not rescue — it reduces fermentation substrate before it reaches the colon, not gas that's already formed.

Can I take too much cellulase?

Cellulase is generally considered very safe, with no established upper limit for supplemental use. However, excessively high doses are unnecessary and wasteful — the enzyme has a saturation point relative to the substrate available in your meal. Follow product label directions and work with a practitioner if you're considering high-dose protocols.

Is cellulase safe during pregnancy or breastfeeding?

There is insufficient clinical data to confirm safety during pregnancy or breastfeeding. Consult your OB/GYN or midwife before starting any new supplement during pregnancy.

Final Verdict: How to Buy Clean Cellulase Supplement

Here's the complete framework for making a confident, well-informed decision when you're ready to buy clean cellulase supplement products.

Your Clean Cellulase Buying Checklist

✅ Cellulase activity listed in CU (Cellulase Units), not just mg This is non-negotiable. If CU isn't on the label, the product fails the transparency test before you've even read the other ingredients.

✅ Short, clean "Other Ingredients" list Ideal: HPMC or pullulan capsule, nothing else. Acceptable: one or two minor clean additions (organic rice flour, ascorbic acid). Unacceptable: more than three fillers, any artificial colors or flavors.

✅ Non-GMO verified by a third party Look for Non-GMO Project Verified or equivalent certification, not just a "non-GMO" claim printed on the front panel.

✅ Third-party tested with available COA The brand should be able to provide a current Certificate of Analysis from an independent laboratory confirming potency and purity.

✅ Clearly stated enzyme source (fungal species named) Quality brands disclose that their cellulase is from Aspergillus niger or Trichoderma reesei — not a generic "plant source" claim.

✅ Multi-enzyme formula with cellulase as a leading ingredient Unless you have a specific reason for standalone cellulase, a well-formulated blend covering cellulose, starch, protein, fat, lactose, and oligosaccharides will serve most people better.

✅ Vegan capsule if relevant to your diet HPMC (hydroxypropyl methylcellulose) or pullulan are the standard vegan capsule materials. Standard gelatin capsules are animal-derived.

✅ Reasonable price point for the quality tier Quality certified multi-enzyme blends typically retail for $25–$55 for a 60–90 count supply. Below $15 for a certified clean-label product is a red flag. Above $80 for a standard formula without exceptional certification is potentially overpriced.

Format Decision Summary

| Your Situation | Best Format | |---|---| | Everyday digestive support, mixed diet | Clean multi-enzyme capsule with cellulase | | Strong preference for liquid supplements | Best clean cellulase drops formula | | Swallowing difficulty (elderly, pediatric) | Cellulase enzyme drops | | Adding to smoothies or soft foods | Cellulase enzyme drops | | Maximum enzyme variety + convenience | Multi-enzyme capsule formula | | Traveling frequently | Capsule (more stable, spill-proof) |

The Bottom Line

Cellulase for gas and bloating works through a biologically plausible and mechanistically sound pathway — breaking down plant cell wall cellulose before it reaches colonic bacteria and becomes fermentation fuel. The clinical evidence base for isolated cellulase is genuinely weak, but the evidence for multi-enzyme blends containing cellulase is more encouraging, and real-world use data is substantial.

What you choose in terms of product quality should match what you're putting into your body. A clean label cellulase supplement — no fillers, disclosed enzyme activity in CU, non-GMO, third-party tested, with a transparent ingredient panel — is not a luxury tier choice. It's the baseline standard you should hold all digestive enzyme supplements to.

If you're eating a plant-forward diet, increasing your fiber intake, or consistently bloated after vegetable-heavy meals, cellulase for vegetable digestion as part of a quality multi-enzyme formula is a logical, low-risk, and potentially meaningful addition to your digestive health routine.
