What Is a Digestive Enzyme Blend and Why Does It Matter for Leaky Gut?

If you have been searching for a digestive enzyme blend for leaky gut, you have probably already spent hours wading through conflicting advice, products with vague labels, and marketing claims that feel impossible to verify. You are not alone — and this guide is designed to cut through all of that noise and give you a clear, honest, research-informed answer.

Let's start at the beginning.

Digestive enzymes are proteins your body naturally produces to break down the food you eat. They are secreted primarily in your pancreas, small intestine, and saliva. The major categories include:

• Proteases — break down proteins into amino acids
• Lipases — break down fats into fatty acids and glycerol
• Amylases — break down carbohydrates into simple sugars
• Lactase — specifically breaks down lactose, the sugar in dairy
• Cellulases — help break down plant fiber (not produced by humans naturally)
• Nucleases — help break down nucleic acids from food

A digestive enzyme blend is a supplement that combines multiple enzyme types into a single formula. The goal is to support more complete digestion across all macronutrient categories — something a single-enzyme product cannot do.

So what does this have to do with leaky gut?

Leaky gut — formally called intestinal hyperpermeability — refers to a condition in which the tight junctions between the cells lining your intestinal wall become loose or compromised. When this happens, partially digested food particles, toxins, and bacteria can pass through the gut lining and enter the bloodstream, triggering immune responses and systemic inflammation.

Here is the connection: when you do not break down food properly, large, undigested food particles sit in your gut and can irritate the intestinal lining. Over time, this chronic irritation can contribute to increased intestinal permeability. By improving digestion upstream — before food particles ever reach the sensitive lower gut — a well-formulated digestive enzyme blend leaky gut supplement may help reduce this irritation and support a healthier gut environment.

This is why thousands of people with conditions like IBS, Crohn's disease, food intolerances, and general digestive discomfort have turned to enzyme blends as part of their gut healing protocol.

What the Science Actually Says

Let's be straightforward here: the science on digestive enzyme blends specifically for leaky gut is still developing. Here is what the current research landscape actually shows, without overstating the evidence.

The 2024 Review: A Landmark Overview

A 2024 review titled Leaky Gut and the Ingredients That Help Treat It examined the full ingredient landscape related to intestinal permeability and gut barrier function. Digestive enzymes — including proteases, lipases, amylases, and nucleases — were discussed as part of this broader conversation.

Importantly, the review does not position any single enzyme blend as a clinically proven treatment for leaky gut as a standalone diagnosis. Instead, it frames digestive enzymes as part of a multi-ingredient approach to gut health, where the combination of well-chosen compounds may produce meaningful results.

L-Glutamine and Tight Junction Proteins

The same 2024 review highlighted glutamine as one of the more compelling gut-lining ingredients, noting that it is considered capable of regulating tight junction proteins — the very proteins that become compromised in leaky gut. Preclinical studies have found improvements in fibrosis and intestinal inflammation following glutamine supplementation.

Earlier human research is also encouraging. A 2015 study found that L-glutamine can improve enterocyte growth and survival and regulate the intestinal barrier during periods of physiological stress. A more recent small-scale study showed that oral glutamine supplementation improved intestinal permeability markers after strenuous exercise — a meaningful finding given that physical stress is a known trigger for temporary gut barrier disruption.

Zinc and the Intestinal Lining

Research on zinc and the gut goes back further. A 2001 study in Crohn's disease patients examined zinc's role in gut integrity, and 2015 work suggested that zinc can modify tight junctions in the intestinal lining — supporting its inclusion in comprehensive gut-support formulas.

Polyphenols and Permeability

The 2024 review also highlighted several polyphenolic compounds — quercetin, curcumin, berberine, resveratrol, catechin, and epigallocatechin gallate (EGCG) — as having been studied for decreasing intestinal permeability, primarily through anti-inflammatory signaling pathways. These compounds are increasingly appearing in premium digestive health blends alongside enzyme complexes.

Glutamine + Probiotics: A Synergistic Combination

One of the more interesting findings from the 2024 review involves the pairing of glutamine and probiotics. The review suggests that glutamine plus probiotics may have synergistic effects in severe gut disorders by:

• Increasing beneficial Lactobacillus populations
• Reducing Gram-negative bacteria growth
• Improving overall gut flora structure
• Reducing intestinal permeability markers
• Lowering endotoxin levels in the bloodstream

This finding has significant implications for buyers: it suggests that a digestive enzyme blend leaky gut supplement that also includes probiotics or pairs well with a probiotic may deliver stronger results than enzymes alone.

Safety Profile

A review specifically examining digestive enzyme supplements reported that side-effect studies found little or no issues with digestive enzymes across the examined literature. This is reassuring for those who are concerned about taking enzyme supplements long-term, though individual responses can vary and you should always consult a healthcare provider if you have a diagnosed digestive condition.

Key Ingredients to Look For in a Digestive Enzyme Blend Leaky Gut Supplement

Not all enzyme blends are created equal. When you are shopping for a digestive enzyme blend leaky gut supplement, here is what the label should ideally show:

Core Enzymes (Non-Negotiable)

| Enzyme | Function | Why It Matters for Leaky Gut | |---|---|---| | Protease (I, II, III) | Breaks down proteins | Reduces undigested protein fragments that irritate the gut lining | | Lipase | Breaks down fats | Improves fat absorption; reduces fat malabsorption-related inflammation | | Amylase | Breaks down carbohydrates | Reduces fermentable carbohydrate load in the lower gut | | Lactase | Breaks down lactose | Critical for dairy-sensitive individuals | | Cellulase | Breaks down plant fiber | Helps process vegetables that can cause gas and bloating | | Bromelain | Protein-digesting enzyme from pineapple | Anti-inflammatory properties; well-studied | | Papain | Protein-digesting enzyme from papaya | Supports protein breakdown; gentle on the gut |

Gut-Lining Support Ingredients (Highly Beneficial)

• L-Glutamine — the most well-researched amino acid for tight junction support
• Zinc — shown to modify tight junction proteins in the intestinal lining
• Quercetin — polyphenol studied for reducing intestinal permeability
• DGL (Deglycyrrhizinated Licorice) — soothes the intestinal lining
• Slippery Elm Bark — mucilaginous herb that coats and calms the gut wall
• Marshmallow Root — similar mucilaginous action to slippery elm

Probiotic Additions (Synergistic)

Given the 2024 finding on glutamine plus probiotics, blends that include Lactobacillus and Bifidobacterium strains alongside their enzyme complex represent an evolved, science-aligned approach to leaky gut support.

Ingredients to Avoid

• Artificial fillers, dyes, and binders
• Titanium dioxide
• High doses of synthetic additives
• Formulas without disclosed enzyme activity units (measured in HUT, FIP, DU, etc.)

Digestive Enzyme Blend Benefits Leaky Gut Sufferers Care About Most

When people search for digestive enzyme blend benefits leaky gut, they are usually looking for answers to a very practical question: Will this actually make me feel better?

Here is a realistic breakdown of the benefits that are reported most commonly and have some degree of research backing:

1. Reduced Bloating and Gas After Meals

This is the most immediately noticeable benefit for most people. When enzymes are working properly, food is broken down more completely before it reaches the large intestine, where bacteria ferment undigested carbohydrates and proteins and produce gas. Many users report significantly reduced bloating within the first week of consistent use.

2. Improved Nutrient Absorption

Leaky gut is often accompanied by nutrient malabsorption — particularly of fat-soluble vitamins (A, D, E, K), B vitamins, magnesium, and zinc. A digestive enzyme blend supports more complete macronutrient breakdown, which creates more bioavailable nutrients for absorption in the small intestine.

3. Reduced Food Sensitivity Reactions

Undigested food proteins — particularly gluten and casein — are among the most commonly reported triggers of immune reactions in people with intestinal hyperpermeability. By improving protein breakdown with proteases, an enzyme blend may reduce the antigenic load reaching the gut wall.

4. Support for Intestinal Lining Integrity

When paired with L-glutamine, zinc, and polyphenols like quercetin, a comprehensive enzyme blend contributes to a multi-pronged approach that addresses both the upstream cause (poor digestion) and the downstream effect (gut lining damage).

5. Less Post-Meal Fatigue

Many people with leaky gut experience significant fatigue after eating — sometimes called "food coma" — which may be related to immune activation following the passage of food particles through a permeable gut wall. Better digestion before food reaches the sensitive lower gut may reduce this response over time.

6. More Comfortable Bowel Movements

Both constipation and diarrhea are commonly reported in people with intestinal permeability issues. Enzyme support can help normalize transit and reduce the urgency, cramping, and irregularity that many sufferers experience daily.

Digestive Enzyme Blend Dosage Leaky Gut Guidelines

One of the most searched questions in this space is around digestive enzyme blend dosage leaky gut — how much to take, when to take it, and for how long.

Here are evidence-informed guidelines:

General Dosage Principles

When to take: Digestive enzymes should generally be taken at the beginning of a meal or within the first few bites. This allows them to be present in the stomach as food arrives and mix with the contents as digestion begins. Some broad-spectrum formulas work well when taken just before a meal as well.

How much to take: Follow the product label's recommended serving size, which is typically 1–3 capsules per meal depending on the concentration of the formula. Higher-potency formulas may require only one capsule; broader, lower-potency blends may call for two or three.

Frequency: Take with every main meal, especially those that contain a mix of proteins, fats, and carbohydrates. For lighter snacks or fruit-only consumption, you may not need enzyme support.

Dosage by Condition Context

| Situation | Suggested Approach | |---|---| | General digestive discomfort | 1–2 capsules with main meals | | Known food intolerances | Include lactase or specific enzymes targeting the offending food | | Active leaky gut protocol | Combine with L-glutamine (5–10g/day) and probiotics | | Post-antibiotic gut recovery | Pair enzymes with a high-quality probiotic | | IBS or Crohn's (under medical supervision) | Higher-potency formula; discuss with gastroenterologist |

How Long Before You Notice Results?

Most people report noticeable improvement in bloating and post-meal comfort within 1–2 weeks of consistent use. Deeper gut-lining repair — reflected in reduced food sensitivity reactions and improved energy — typically takes 4–12 weeks depending on the severity of the underlying permeability issue.

Important Dosage Cautions

• Do not take digestive enzymes on an empty stomach as a first approach if you have a history of stomach ulcers or gastritis — the enzymes may irritate an already-sensitive stomach lining
• People with pancreatitis or pancreatic insufficiency should work with a gastroenterologist to determine appropriate enzyme dosing
• Pregnant or breastfeeding individuals should consult a healthcare provider before starting any new supplement

Digestive Enzyme Blend Tea Leaky Gut: Does It Work?

You may have come across products marketed as a digestive enzyme blend tea leaky gut solution — herbal teas or infused drinks that claim to deliver digestive enzyme support along with gut-soothing botanicals. Let's look at this category honestly.

What These Products Typically Contain

Digestive enzyme teas for leaky gut usually combine:

• Ginger root — well-studied for gastroparesis and nausea; stimulates gastric motility
• Peppermint — relaxes intestinal smooth muscle; reduces bloating and cramping
• Licorice root (DGL form) — soothes the intestinal lining
• Fennel seed — carminative; reduces gas and bloating
• Chamomile — anti-inflammatory and antispasmodic
• Papaya leaf — natural source of papain (a proteolytic enzyme)
• Pineapple pieces — natural source of bromelain

The Honest Assessment

Here is the important nuance: most teas cannot deliver clinically meaningful enzyme activity. The heat involved in steeping tea can denature (deactivate) enzyme proteins, particularly if the water temperature is above 140°F (60°C). This means the enzyme content in many teas may be minimal or nonexistent by the time you drink them.

That said, digestive enzyme blend tea leaky gut products still offer genuine value — just not primarily from the enzyme content. The botanical ingredients provide real anti-inflammatory, carminative, and gut-soothing benefits. Ginger, peppermint, and chamomile teas have legitimate evidence for easing digestive discomfort.

Bottom Line on Teas

Think of digestive enzyme teas as a complementary soothing ritual rather than a replacement for a high-potency supplement capsule. They can absolutely be part of your leaky gut protocol — particularly after meals or before bed — but pair them with a proper supplement-grade enzyme blend for meaningful therapeutic results.

Best teas to look for: Ginger-peppermint blends, chamomile-fennel formulas, and teas that include papaya leaf or pineapple extract for their natural enzyme precursors.

Digestive Enzyme Blend Extract Leaky Gut Formulas Explained

Another category worth understanding is the digestive enzyme blend extract leaky gut product space — these are formulas that use concentrated botanical or fermented extracts as the enzyme source rather than isolated enzyme proteins.

What "Extract" Means in This Context

In supplement labeling, "extract" can mean two different things:

1. Plant extracts with naturally occurring enzyme activity — such as papaya fruit extract (containing papain), pineapple extract (containing bromelain), kiwi extract (containing actinidin), or ginger extract (containing zingibain). These are standardized to a certain level of enzyme activity.

1. Fermentation-derived microbial extracts — enzymes produced through the fermentation of fungi like Aspergillus oryzae or Aspergillus niger. These are technically "extracts" in the manufacturing sense and are extremely common in plant-based enzyme supplements.

Why Extracts Can Be Beneficial for Leaky Gut

Digestive enzyme blend extract leaky gut formulas often carry additional phytonutrient benefits alongside the enzymes themselves:

• Papaya extract delivers not just papain but also antioxidants and carotenoids
• Ginger extract provides gingerols and shogaols with documented anti-inflammatory effects
• Turmeric extract (sometimes included for its curcumin content) addresses intestinal permeability through anti-inflammatory signaling pathways — which aligns with the 2024 review's findings on curcumin and gut barrier function

What to Look for on Labels

When evaluating a digestive enzyme blend extract product, look for:

• Standardization information — e.g., "papaya extract standardized to 10% papain activity" or "bromelain 2,400 GDU/g"
• Activity units disclosed — not just the weight of the extract in milligrams but the actual enzymatic activity it delivers
• No proprietary blends that hide individual extract doses — transparency matters when you are buying for a therapeutic purpose

Natural Digestive Enzyme Blend Leaky Gut Options

Many people looking for a natural digestive enzyme blend leaky gut solution prefer to avoid synthetic additives, animal-derived ingredients, and pharmaceutical manufacturing processes. The good news is that the natural enzyme category has matured significantly and now includes some genuinely excellent options.

Food-Based Natural Enzyme Sources

Before we get to supplements, it is worth noting the whole-food sources of digestive enzymes that you can incorporate into your diet:

| Food | Enzyme(s) | Best For | |---|---|---| | Pineapple | Bromelain (protease) | Protein digestion; anti-inflammatory | | Papaya | Papain (protease) | Protein breakdown; especially raw | | Mango | Amylases | Carbohydrate digestion | | Kiwi | Actinidin (protease) | Protein digestion; gut motility | | Avocado | Lipase | Fat digestion | | Raw honey | Amylase, diastase | Carbohydrate support | | Sauerkraut/kimchi | Microbial enzymes + probiotics | Broad digestive support | | Ginger (raw) | Zingibain (protease) | Protein digestion; gastroparesis support |

Natural Supplement Enzyme Sources

For supplement-form natural options, look for products that source their enzymes from:

• Fermentation of Aspergillus, Rhizopus, or Trichoderma species — these are considered natural, food-grade fermentation processes
• Papaya fruit standardized extracts
• Pineapple stem extract (where bromelain is most concentrated)
• Kiwi extract (actinidin-rich)

What "Natural" Should Mean on the Label

A genuinely natural digestive enzyme blend leaky gut supplement should be:

• Free of synthetic dyes, artificial flavors, and chemical preservatives
• In a vegetarian or vegan capsule (not gelatin, unless animal-sourced is acceptable to you)
• Manufactured without use of hexane or harsh solvents in extraction
• Third-party tested for purity
• Free of GMO-derived ingredients if that matters to you (look for Non-GMO Project Verified)

Can You Combine Digestive Enzymes With Glutamine, Probiotics, or Collagen?

This is one of the most practical questions buyers ask, and the answer is a clear yes — with some nuance.

Enzymes + L-Glutamine

This is arguably the most well-supported combination for leaky gut support. As the 2024 review noted, glutamine can regulate tight junction proteins, which are the structural proteins that keep the gut lining sealed. Digestive enzymes address the upstream cause (incomplete digestion); glutamine addresses the downstream effect (gut lining damage).

How to combine: Take your enzyme blend with meals; take L-glutamine either with meals or on an empty stomach first thing in the morning. A common therapeutic dose in research contexts is 5–10 grams of L-glutamine per day, though always confirm appropriate dosing with your healthcare provider.

Enzymes + Probiotics

The 2024 review's finding on glutamine plus probiotics extends naturally to enzyme plus probiotic combinations. Probiotics help reestablish a healthy gut microbiome, which in turn creates a better environment for the gut lining to heal. Enzymes improve the substrate that reaches the colon — better-digested food means more prebiotic fiber available for beneficial bacteria and less putrefactive byproducts from poorly digested protein.

How to combine: Take probiotics with a meal (some prefer morning; others prefer with dinner). Enzymes should be taken at the start of each main meal. These do not interfere with each other.

Enzymes + Collagen Peptides

Collagen contains high levels of glycine, proline, and hydroxyproline — amino acids that support the integrity of the gut lining connective tissue. Pairing a digestive enzyme blend (particularly one with proteases and peptidases) with collagen peptides may actually help ensure better absorption of the collagen's amino acids.

How to combine: Collagen powder can be mixed into a morning beverage. Take enzymes with your first main meal of the day.

Enzymes + Zinc

Given the evidence on zinc modifying tight junctions in the intestinal lining, choosing an enzyme blend that already includes zinc or adding a separate zinc supplement (zinc carnosine is particularly well-studied for gut lining support) is a smart strategy.

What NOT to Combine

• Avoid taking high-dose digestive enzymes with blood-thinning medications without medical supervision — bromelain in particular has mild antiplatelet activity
• Do not take enzymes as a substitute for prescribed pancreatic enzyme replacement therapy (PERT) if you have been diagnosed with exocrine pancreatic insufficiency — your prescribed dose is calculated specifically for your condition

How To Spot a High-Quality Product

With hundreds of enzyme blends on the market, here is your quick-reference checklist for evaluating whether a product is worth your money:

✅ Certification Checklist

• [ ] GMP certified (Good Manufacturing Practices) — this is the minimum standard; look for NSF GMP or USP GMP for higher verification
• [ ] Third-party tested — NSF International, USP, Informed Sport, or ConsumerLab tested
• [ ] Non-GMO Project Verified (if important to you)
• [ ] Allergen statement — clearly states free of gluten, dairy, soy, nuts if relevant to your needs

✅ Label Transparency Checklist

• [ ] Enzyme activity units are disclosed (HUT for protease, FIP for lipase, DU for amylase, ALU for lactase, etc.) — not just milligrams
• [ ] No proprietary blends that hide individual enzyme doses
• [ ] Full inactive ingredient list disclosed
• [ ] Clear serving size and servings per container

✅ Formulation Quality Checklist

• [ ] At least 6–8 different enzyme types for broad-spectrum coverage

Frequently Asked Questions

Q: Do digestive enzymes actually help with intestinal permeability?

A: The direct evidence on digestive enzyme blends specifically treating intestinal permeability is still emerging. The 2024 review on leaky gut ingredients discusses digestive enzymes as part of the broader ingredient landscape for gut health, but does not establish them as a standalone clinical treatment for leaky gut. Their most clear benefit is improving upstream digestion, which may reduce irritant load on the gut lining. When combined with L-glutamine, zinc, and probiotics — all of which have more direct evidence for tight junction support — they form a logical and well-rounded protocol.

Q: Should I choose a broad-spectrum formula or a targeted formula?

A: For most people with leaky gut, broad-spectrum is the better starting point. Leaky gut is typically accompanied by generalized digestive impairment, not just sensitivity to one macronutrient. A formula covering proteins, fats, carbohydrates, dairy, and fiber ensures you are supported across a full day of eating. Targeted formulas (such as lactase-only products for lactose intolerance) are more appropriate once you have identified a specific trigger.

Q: Are digestive enzymes safe if I have IBS, Crohn's disease, or food intolerances?

A: Current research suggests a favorable safety profile for digestive enzymes, with studies reporting little or no adverse effects. However, if you have a diagnosed inflammatory bowel condition like Crohn's disease, you should discuss enzyme supplementation with your gastroenterologist before starting, as the appropriate formula and dose may differ from general guidelines. People with known allergies to pineapple or papaya should avoid bromelain and papain specifically.

Q: Can I take digestive enzymes during a flare-up?

A: This depends on the severity of the flare. During an acute inflammatory episode, your priority should be working with your medical team. Gentle, plant-based enzyme formulas are generally better tolerated than high-potency pancreatic enzyme formulas during sensitive periods. When in doubt, wait until the acute phase passes.

Q: How long do I need to take digestive enzymes for leaky gut?

A: There is no universal answer, but most practitioners who work with leaky gut protocols suggest a minimum 3–6 month commitment to a comprehensive protocol (enzymes + glutamine + probiotics + dietary changes). Enzymes specifically can be continued long-term or used situationally (e.g., only with meals known to cause issues). Unlike some supplements, there is no strong evidence of dependence or downregulation of the body's own enzyme production from supplemental use.

Q: Is a digestive enzyme blend tea for leaky gut effective?

A: Teas offer genuine soothing and anti-inflammatory botanical benefits (from ginger, peppermint, chamomile, licorice), but the actual enzyme activity in hot teas is likely minimal due to heat denaturation. Use teas as a complementary ritual, not a replacement for a supplement-grade enzyme blend.

Q: What is the difference between digestive enzymes and probiotics for leaky gut?

A: They work in fundamentally different ways and are highly complementary. Digestive enzymes act in the upper GI tract (stomach and small intestine) to improve breakdown of food before it reaches the large intestine. Probiotics act primarily in the large intestine to reestablish beneficial bacterial populations that support gut lining health and immune regulation. The 2024 research suggesting synergistic effects of glutamine plus probiotics underscores why pairing these strategies makes biological sense.

Q: What does "leaky gut with digestive enzyme blend" protocol look like in practice?

A: A practical daily routine for supporting leaky gut with digestive enzyme blend might look like this:

• Morning: L-glutamine powder (5g) in warm water on empty stomach + probiotic capsule with breakfast
• With each main meal: 1–2 enzyme blend capsules taken at the start of eating
• Evening: Herbal digestive tea (ginger-chamomile) + zinc supplement (15–30mg zinc carnosine) with dinner
• Ongoing: Anti-inflammatory diet (removing gluten, processed sugar, alcohol) + collagen peptides in morning coffee

Q: Is there a difference between digestive enzyme blend extract leaky gut products and standard enzyme supplements?

A: Yes — extract-based formulas derive their enzyme activity from plant or fermentation extracts (like papaya extract or Aspergillus ferment) and often carry additional phytonutrient benefits. Standard pharmaceutical-style enzyme supplements (like porcine pancreatin) use animal-derived or isolated enzyme fractions with predictable, measured activity units. Both can be effective; the extract-based approach tends to align better with the "natural" and "plant-based" preferences of many gut health consumers.

Final Verdict

If you have made it this far, you now have a comprehensive, research-aligned understanding of the digestive enzyme blend leaky gut space — from the science to the shopping.

Let's bring it all together.

The core takeaway: A well-formulated digestive enzyme blend is a genuinely useful tool in a leaky gut recovery protocol. It is not a magic cure, and the evidence base for enzymes specifically treating intestinal permeability is still developing. But by improving upstream digestion — reducing the burden of undigested food particles reaching a sensitive gut lining — a broad-spectrum enzyme blend addresses one of the key contributing mechanisms to intestinal hyperpermeability.

When you pair that with L-glutamine (for tight junction support), zinc (for intestinal lining integrity), probiotics (for microbiome restoration), and anti-inflammatory polyphenols like quercetin and curcumin, you are implementing a protocol that reflects the best current understanding of what the 2024 research suggests about gut barrier support.

The best digestive enzyme blend for leaky gut is one that:

1. Contains at least 6–8 enzyme types including protease, lipase, amylase, and lactase
2. Discloses enzyme activity units on the label
3. Is manufactured in a GMP-certified facility
4. Preferably includes gut-lining support ingredients like L-glutamine and zinc
5. Is third-party tested for purity and potency
6. Is available through a reputable channel where authenticity is guaranteed

Where to buy: For most buyers, iHerb offers the best combination of price, selection, and certification filtering. Amazon is excellent for convenience and reviews but requires caution around seller authenticity. Brand direct websites are ideal for commitment buyers who want subscription pricing. If you have access to a functional medicine practitioner, Fullscript's practitioner channel gives you access to the highest-grade clinical formulas.

Start with a high-quality broad-spectrum enzyme blend, pair it with the synergistic supplements the research supports, and give it a minimum of 8–12 weeks of consistent use alongside dietary changes. Track your symptoms, communicate with your healthcare provider, and adjust as needed.

Your gut has a remarkable capacity to heal — the right enzymatic support can help it get there faster.
