ProHydrolase®
Introduction to Proteolytic Hydrolysis
Protein digestion is a complex, multi-stage process that begins in the stomach with pepsin and continues in the small intestine through the action of pancreatic proteases such as trypsin, chymotrypsin, and elastase. However, the endogenous enzymatic capacity can be overwhelmed by the acute ingestion of large quantities of protein—a common practice among athletes and bodybuilders. When intact proteins or large peptide fragments escape digestion in the upper gastrointestinal tract, they pass into the colon. Here, they undergo bacterial fermentation (putrefaction), leading to the production of gas, bloating, and gastrointestinal discomfort. ProHydrolase® intervenes in this pharmacokinetic bottleneck by providing exogenous proteolytic capacity, ensuring rapid and near-complete hydrolysis of protein substrates before they reach the lower intestine.
The Enzymatic Profile of ProHydrolase
ProHydrolase® is a precision-engineered blend of proteases sourced from two distinct biological origins: *Bacillus subtilis* and *Ananas comosus*. This combination is not arbitrary; it leverages the distinct cleavage specificities of different protease classes to achieve a synergistic breakdown of complex tertiary and quaternary protein structures. The blend is standardized to a specific enzymatic activity, typically measured in Hemoglobin Unit Tyrosine (HUT) assays, with a label claim of 3,500 HUT per 10mg of the enzyme complex. This high specific activity ensures that even small milligram doses can process substantial gram-quantities of dietary protein.
Bacillus Subtilis Protease (Subtilisin) Kinetics
The primary workhorse in the ProHydrolase® matrix is the protease derived from *Bacillus subtilis*, commonly known as subtilisin. Subtilisins are a family of serine proteases that utilize a catalytic triad consisting of serine, histidine, and aspartate to execute nucleophilic attack on the peptide bonds of protein substrates. Unlike highly specific endogenous proteases (e.g., trypsin, which only cleaves at the carboxyl side of lysine and arginine), subtilisin exhibits broad substrate specificity. It acts as a robust endopeptidase, cleaving internal peptide bonds within the protein chain. This broad-spectrum activity is crucial for dismantling the tightly folded globular structures of whey, casein, and various plant-based proteins (such as pea, rice, and soy). By rapidly reducing large polypeptides into smaller oligopeptides, subtilisin creates a multitude of new terminal ends for exopeptidases to act upon, exponentially increasing the rate of total protein hydrolysis.
Ananas Comosus (Bromelain) Cysteine Protease Activity
Complementing the serine protease activity of subtilisin is the protease extract from *Ananas comosus* (pineapple), widely recognized as bromelain. Bromelain belongs to the family of cysteine proteases, which rely on a catalytic dyad or triad involving a nucleophilic cysteine thiol group. Bromelain exhibits both endopeptidase and exopeptidase activities, with a preference for cleaving peptide bonds adjacent to basic amino acids and aromatic residues. The inclusion of bromelain in ProHydrolase® serves a dual purpose. First, it broadens the overall cleavage profile of the blend, ensuring that peptide bonds resistant to subtilisin are effectively hydrolyzed. Second, bromelain is highly stable across a wide range of pH levels, allowing it to remain active in the acidic environment of the stomach as well as the more neutral environment of the duodenum. This continuous activity profile ensures that protein breakdown begins immediately upon ingestion and continues seamlessly as the chyme transitions through the gastrointestinal tract.
Synergistic Cleavage and Peptide Generation
The true biochemical advantage of ProHydrolase® lies in the synergistic action of its constituent proteases. When a protein supplement is ingested alongside ProHydrolase®, the subtilisin and bromelain enzymes immediately begin attacking the protein matrix. Subtilisin rapidly fragments the large protein molecules into intermediate-sized oligopeptides. Simultaneously, bromelain further degrades these oligopeptides into di-peptides, tri-peptides, and free amino acids. This rapid, multi-targeted hydrolysis prevents the formation of large, indigestible protein aggregates. Clinical studies, such as those referenced by PMID 31978998, demonstrate that this accelerated breakdown significantly increases the availability of bio-usable peptides in the systemic circulation.
Pharmacokinetics and Intestinal Transport (PepT1)
The ultimate goal of protein ingestion is to elevate plasma amino acid concentrations to stimulate muscle protein synthesis (MPS). The intestinal absorption of protein breakdown products is mediated primarily by two mechanisms: specific amino acid transporters for free amino acids, and the Peptide Transporter 1 (PepT1) for di- and tri-peptides. Interestingly, the transport of di- and tri-peptides via PepT1 is kinetically faster and more energy-efficient than the transport of free amino acids. ProHydrolase® is specifically formulated to maximize the yield of these highly absorbable di- and tri-peptides. By shifting the equilibrium of digestion away from large polypeptides and toward these smaller, transport-ready molecules, ProHydrolase® accelerates the appearance of amino acids in the bloodstream. This rapid hyperaminoacidemia is a potent trigger for the mechanistic target of rapamycin (mTOR) pathway, the primary driver of muscle hypertrophy.
Mitigation of Colonic Putrefaction and GI Distress
Beyond maximizing anabolic signaling, ProHydrolase® plays a critical role in gastrointestinal health. When high doses of protein (particularly plant-based proteins, which often contain anti-nutritional factors that inhibit endogenous proteases) are consumed, a significant fraction may escape small intestinal absorption. Upon reaching the colon, these undigested proteins are metabolized by the resident microbiota. This process, known as putrefaction, generates a variety of metabolic byproducts, including ammonia, hydrogen sulfide, indoles, and phenols. These compounds are responsible for the foul-smelling gas, bloating, and abdominal discomfort frequently reported by individuals consuming high-protein diets. By ensuring that protein is thoroughly hydrolyzed and absorbed in the upper GI tract, ProHydrolase® effectively starves the colonic bacteria of this proteinaceous substrate, thereby eliminating the root cause of "protein bloat." This makes ProHydrolase® an invaluable addition to both whey and plant-based protein formulations, enhancing not only their nutritional efficacy but also their tolerability.

Everything About ProHydrolase® Article
The Ultimate Guide to ProHydrolase®
If you've ever chugged a large protein shake after a grueling workout only to feel bloated, sluggish, and uncomfortably full for hours, you are not alone. This phenomenon, often referred to in gym culture as "protein bloat," is a clear sign that your body is struggling to digest and absorb the protein you've consumed. Enter ProHydrolase®, a patented, clinically studied digestive enzyme blend designed specifically to solve this problem. By breaking down complex proteins into highly bioavailable peptides, ProHydrolase® ensures that your expensive protein powder actually goes toward building muscle, rather than feeding the gas-producing bacteria in your gut.
What is ProHydrolase?
ProHydrolase® is a proprietary proteolytic enzyme blend developed by Deerland Probiotics & Enzymes. It is formulated using two primary sources: protease derived from Bacillus subtilis (a beneficial bacteria) and protease derived from Ananas comosus (the pineapple plant, commonly known as bromelain).
Unlike generic digestive enzyme supplements that contain a kitchen-sink approach of amylases, lipases, and weak proteases, ProHydrolase is hyper-focused on one task: the rapid and complete hydrolysis of dietary protein. It is standardized to deliver a potent 3,500 HUT (Hemoglobin Unit Tyrosine) of enzymatic activity per 10mg dose, ensuring it has the biochemical power to dismantle large quantities of protein quickly and efficiently.
The Problem with Standard Protein Supplements
To understand why ProHydrolase is necessary, we must first look at how the body processes protein. When you consume a whey, casein, or plant-based protein shake, you are ingesting massive, complex molecules folded into intricate three-dimensional structures. Your body must break these massive structures down into individual amino acids or small chains called di-peptides and tri-peptides before they can cross the intestinal wall and enter your bloodstream.
Your stomach produces pepsin, and your pancreas secretes trypsin and chymotrypsin to handle this job. However, when you dump 30 to 50 grams of liquid protein into your system all at once, your endogenous (internal) enzyme production can be overwhelmed.
When protein is not fully broken down in the stomach and small intestine, large, intact peptide chains continue their journey into the large intestine (colon). Here, they meet your gut microbiome. The bacteria in your colon ferment these undigested proteins in a process known as putrefaction. The byproducts of putrefaction include hydrogen sulfide, ammonia, and other gases. This is the exact mechanism behind the bloating, cramping, and foul-smelling gas that plagues many athletes and bodybuilders.
How ProHydrolase Optimizes Protein Absorption
ProHydrolase acts as a powerful exogenous (external) digestive aid that steps in to assist your body's natural enzymes. The specific combination of Bacillus subtilis and Ananas comosus proteases is what makes it so effective.
The Power of Subtilisin and Bromelain Bacillus subtilis produces a class of enzymes called subtilisins. These are broad-spectrum endopeptidases, meaning they act like molecular scissors, cutting the long protein chains right down the middle to create smaller fragments.
Meanwhile, the bromelain from Ananas comosus acts as both an endopeptidase and an exopeptidase, snipping amino acids off the ends of these newly created fragments. Together, they work synergistically to rapidly reduce a thick, heavy protein shake into a liquid pool of bio-usable di-peptides, tri-peptides, and free amino acids.
The PepT1 Transporter Advantage From a pharmacokinetic standpoint, the body actually prefers to absorb di-peptides and tri-peptides over single, free amino acids. The intestinal lining contains a specialized transport protein called PepT1, which acts like an express lane for these small peptide chains. Because ProHydrolase is specifically engineered to maximize the yield of di- and tri-peptides, it effectively forces the protein through the PepT1 express lane, resulting in a faster, more dramatic spike in blood amino acid levels.
Key Benefits for Athletes and Bodybuilders
For anyone engaged in resistance training, the speed and efficiency of protein absorption are critical factors in recovery and muscle growth.
1. Amplified Muscle Protein Synthesis (MPS) Muscle growth is triggered by a biological pathway known as mTOR. To activate mTOR, you need a rapid influx of essential amino acids, particularly leucine, into the bloodstream. Because ProHydrolase accelerates the breakdown and absorption of protein, it creates a sharper, higher peak in blood amino acid concentrations compared to consuming protein alone. This hyperaminoacidemia is a potent signal for your body to flip the switch from muscle breakdown (catabolism) to muscle building (anabolism).
2. Banishing the "Protein Bloat" As established, bloating occurs when undigested protein reaches the colon. By ensuring that nearly 100% of the ingested protein is hydrolyzed and absorbed in the upper GI tract, ProHydrolase starves the colonic bacteria of their fuel source. The result? You can drink a heavy post-workout shake and feel light, energized, and comfortable, rather than sluggish and distended.
3. Leveling Up Plant-Based Proteins While whey protein is naturally fast-digesting, plant-based proteins (like pea, rice, hemp, and soy) present a unique challenge. Plant proteins are often bound in tough fibrous matrices and naturally contain anti-nutritional factors (like trypsin inhibitors) that actively fight against your body's digestive enzymes. This is why many people find vegan protein powders heavy and hard to digest. ProHydrolase is a game-changer for plant proteins. Its robust enzymatic activity easily cuts through these barriers, breaking down plant proteins just as efficiently as whey, thereby increasing their biological value and making them a viable option for serious athletes.
Clinical Evidence and Efficacy
The claims behind ProHydrolase are not just theoretical; they are backed by clinical research. Studies, such as the one published in the Sports (Basel) journal (PMID: 31978998), have investigated the effects of adding ProHydrolase to whey protein. The findings consistently show that the inclusion of this specific enzyme blend significantly increases the availability of amino acids in the blood and drastically reduces the presence of large, indigestible protein fractions. This means more protein for your muscles and less waste for your gut.
Dosage and Supplement Stacking
When looking for ProHydrolase on a supplement label, dosage matters. The clinical standard is typically around 10mg to 25mg per serving of protein. Because it is highly concentrated (yielding 3,500 HUT per 10mg), you do not need massive doses to see the benefits.
You will most commonly find ProHydrolase pre-blended into high-quality whey protein isolates, mass gainers, and premium plant-based protein powders. If you are purchasing it as a standalone digestive enzyme supplement, take it immediately before or alongside your protein-heavy meals or shakes.
Safety and Side Effects
ProHydrolase is exceptionally safe for the vast majority of the population. It is Non-GMO, Vegan, Halal, and Kosher certified. Because it works entirely within the gastrointestinal tract and is not absorbed into the bloodstream as an intact enzyme, systemic side effects are virtually non-existent.
However, there are two minor caveats. First, because it contains bromelain derived from pineapple, individuals with severe pineapple allergies should avoid it. Second, bromelain has very mild blood-thinning properties. While the dose in ProHydrolase is generally too low to cause issues, individuals on prescription anticoagulant medications or those with bleeding disorders should consult a physician before use.
The Bottom Line
If you are investing your hard-earned money into premium protein powders, it makes no sense to let a significant portion of that protein go to waste in your digestive tract. ProHydrolase® is a scientifically validated, highly effective solution for maximizing amino acid absorption, accelerating muscle recovery, and completely eliminating the uncomfortable bloating associated with high-protein diets. Whether you are a competitive bodybuilder or just someone looking to get the most out of your post-workout shake, ProHydrolase is an ingredient worth looking for on the label.
