Many health practitioners
today are advising patients to take proteolytic enzymes to help with everything from
inflammation and autoimmune conditions to heart disease and
Some doctors have even suggested its use
for the treatment of cancer. So, what are these powerful enzymes and why should you
know about them?
In order to understand proteolytic enzymes, it's important to have a basic
understanding of enzymes in the body. Enzymes are proteins that facilitate chemical
reactions in living organisms. In fact, they are required for every single chemical
action that takes place in your body. All of your tissues, muscles, bones, organs
and cells are run by enzymes.
Your digestive system, immune system, bloodstream, liver, kidneys, spleen and
pancreas, as well as your ability to see, think, feel and breathe, all depend on
enzymes. All of the minerals and vitamins you eat, and all of the hormones your
body produces need enzymes in order to work properly. In fact, enzymes govern every
single metabolic function in your body: your stamina, energy level, ability to utilize
vitamins and minerals, immune system and more. The vast majority of metabolic enzymes
in the body the enzymes that regulate everything from liver function to the
immune system are proteases, or proteolytic enzymes, which regulate protein function
in the body. When we eat foods that are enzyme dead (cooked or processed), we force
the body to divert its production of enzymes away from proteolytic enzymes, which
govern metabolic functions, into digestive proteolytic enzymes designed to break down
dead proteins in our diets. The consequences of this'diversion are enormous.
Conversely, the benefits of supplementing with proteolytic enzymes are profound.
And by supplementing, I mean:
Supplementing with "digestive" proteolytic enzymes at meals to ease the
burden on the body, so it no longer has to divert its resources.
Supplementing with "special" proteolytic enzymes between meals, so the enzymes can enter the
bloodstream and augment the proteolytic functions of our metabolic enzymes.
It's possible to use good-quality digestive enzymes for both functions and
receive a significant amount of benefit. But it's far more beneficial to use formulas
that are optimized for each particular function. With that in mind, let's now look at
some of the profound benefits of supplementing with a dedicated proteolytic formula.
- Reducing inflammation: Inflammation is a natural response of the body to
injury. However, excessive inflammation retards the healing process. Proteolytic
enzymes reduce inflammation by neutralizing the biochemicals of inflammation
(i.e., bradykinins and pro-inflammatory eicosanoids) to levels at which the
synthesis, repair and regeneration of injured tissues can take
place.1 Reducing inflammation can have immediate impact on improved heart health, cancer prevention and
recovery, and Alzheimer's prevention. It also helps speed up recovery from sprains,
strains, fractures, bruises, contusions, surgery and arthritis. In one study,
football players who suffered from ankle injuries found that proteolytic enzyme
supplements accelerated healing and got the players back on the field 50 percent faster
than athletes who received placebo
tablets.2 Other trials have shown that
supplemental proteolytic enzymes can help reduce inflammation, speed healing of bruises
and other tissue injuries (including fractures), and reduce overall recovery time
when compared to athletes taking a
placebo.3,4 And even in patients recovering
from facial and various reconstructive surgeries, treatment with proteolytic
enzymes significantly reduced swelling, bruising and stiffness compared to
- Cleansing the blood of debris: Proteolytic enzymes are the primary tools
the body uses to "digest" organic debris in the circulatory and lymph systems.
Supplementing merely improves the effectiveness of the process.
- Dissolving fibrin in the blood, reducing the risk of
clots: Certain specialized proteases such as nattokinase are extremely effective at
improving the "quality" of blood cells, optimizing the ability of blood to flow
through the circulatory system, and reducing the risk of
clots.8 This is extremely important in reducing the risk of stroke. It also makes using
proteolytic enzymes during long plane flights a no-brainer, as they minimize the
potential of blood clots in the legs.
- Maximized immune system: The primary vehicle the immune system uses for
destroying invaders is enzymes. Macrophages, for example, literally digest
invaders with proteolytic enzymes. Supplementation significantly improves the ability
of your immune system to do its job.
- Killing of bacteria, viruses, molds and
fungi: Bacteria, viruses, molds and fungi are protein/
amino acid-based. Proteolytic enzymes taken between meals literally go into
the bloodstream and digest these invaders.
- Elimination of autoimmune diseases: In Lessons from the Miracle Doctors, I cover in detail the process whereby large undigested proteins make their way
into the bloodstream and form circulating immune complexes (CICs), which trigger
allergies and autoimmune diseases. Supplemental proteolytic enzymes clean CICs out
of the body, thereby reducing allergies and autoimmune conditions. In addition,
this helps with sinusitis and asthma.
- Dissolving of scar tissue: Scar tissue is made of protein. Proteolytic enzymes can effectively "digest"
scar tissue particularly in the circulatory system.
- And finally, a properly designed supplemental proteolytic enzyme formula
can help reduce the symptoms of MS, clean out the lungs9 and aid in
The vast majority of metabolic
enzymes in the body the enzymes that
regulate everything from liver function to the immune system are proteases,
or proteolytic enzymes, which regulate protein function in the body.
Clearly, research shows that proteolytic enzymes have incredible health
benefits, which also explains their growing appearance on the shelves of health food
stores. This brings us to the ultimate question: What constitutes a properly designed
supplemental proteolytic enzyme formula?
First, the formula should have high amounts of protease: at least 200,000 HUT.
This is far more than you will ever find in a digestive formula and 300,000 HUT is
even better. It's also important to note that fungal (vegetarian-based) protease is
merely rendered inactive by stomach acid, not destroyed. As soon as it passes into the
alkaline environment of the intestinal tract, it reactivates, and, if not needed
for digesting food, makes its way into the bloodstream. In other words, for use in
a proteolytic enzyme formula, it does not need to be protected from stomach acid.
Second, even though fungal protease does indeed reactivate in the intestinal
tract, the formula will be much more effective if it includes a variety of proteases
that work optimally in a variety of pH ranges. Some of these proteases would include
proper amounts of papain, bromelain and fungal pancreatin.
Third, find a formula that utilizes a special proteolytic enzyme
called nattokinase, which has been discovered to balance optimally the clotting ability
of blood.10 Its ability to control clotting rivals that of pharmaceutical drugs such
as warfarin, but without any of the side effects or downsides, making it valuable
to everyone not just heart disease patients. Obviously, if you already are using
blood thinners, you will need to work with your doctor if you decide to incorporate
proteolytic enzymes in your health program.
Many doctors have asked me about formulas that contain the
"hot" proteolytic enzyme in alternative health right now called serrapeptase. It has remarkable
anti-inflammatory and anti-edemic (i.e., counters swelling and fluid retention) activity in
a number of tissues. In addition to reducing inflammation, serrapeptase has a
profound ability to reduce pain due to its ability to block the release of
pain-inducing amines from inflamed tissues. Finally, it helps clear mucous from the lungs by
reducing neutrophil numbers and altering the viscoelasticity of sputum in patients
with chronic airway diseases. These are all major benefits; however, serrapeptase
has several problems: It has inconsistent quality, causes intestinal distress, and
is sensitive to stomach acid, which means it has to be coated with enteric.
Unfortunately, the technology for enteric-coating of capsules or powders is not reliable
(which is why you normally find enteric coating used only on hard tablets or on hard
beads inside capsules, such as in cold capsules).
There is an alternative to serrapeptase. Seasprose, a specialized proteolytic
enzyme derived from Aspergillus, manufactured in Japan, is of consistent high
quality, causes virtually no intestinal
distress,11 and is not affected by stomach acid, so
it does not require enteric coating. Studies have shown it is more effective
than serrapeptase 85 percent vs. 65
There is one last thing to note when selecting a good proteolytic
enzyme. Be suspicious of any enzyme formula that lists the mgs of enzymes present as opposed
to the activity level of each enzyme in the formula. Activity level determines
overall effect. Two batches of the same enzyme of equal weight can have wildly
different activity levels. The bottom line is that when it comes to enzymes, weight
measurements are just not useful and can be downright misleading, as there is no
direct relationship between weight and units of activity. In fact,
an enzyme can still have a weight even if it has been destroyed and has zero
activity. When comparing enzymes, if you want apples-to-apples comparisons between supplements, then you need to
compare activity levels.
The internationally recognized and accepted standard for measurement is by
Food Chemical Codex (FCC) units. This usually is expressed in different activity units
for each type of enzyme. For instance, protease is measured in HUTs (hemoglobin
units, tyrosine basis), amylase in SKBs (named after the creators of the test,
Sandstedt, Kneen, and Blish) or DUs (used in the brewing industry), and lipase in LUs.
In summary, make sure the proteolytic enzyme formula you use for yourself or
recommend to patients is adequate to the task at hand. At the minimum, a daily dose
- a minimum of 200,000 HUT of fungal protease, designed to function in a wide
- 250 FU nattokinase;
- 10,000 U of the Aspergillus-derived enzyme (if opting for serrapeptase,
look for a minimum of 30,000 IU, enteric coated);
- formula enhancements including ingredients such as papain, bromelain, rutin
Regular use of such a formula can be an invaluable addition to any of your
patient's daily health programs. By helping to reduce pain and inflammation
levels, proteolytic enzymes will not only make adjustments easier to perform, but also
will increase your patient's general satisfaction levels, thereby improving patient
retention. In addition to regular use, however, there is the option of using
proteolytic at therapeutic levels for 14 to 30 days or longer, if necessary, for periodic
enzyme detox and rebuilding programs. Such programs can go a long way to improving
circulation, removing scar tissue, cleaning out the lungs and correcting autoimmune
problems. These kinds of results literally can be life-changing; possibly even
