FREQUENTLY ASKED QUESTIONS
What are enzymes and what do they do?
are essential nutrients that make life possible. Enzymes are needed
for every chemical reaction that takes place in the human body. No
mineral, vitamin, or hormone can do any work without enzymes. Vitamin
and minerals, also known as co-enzymes, are only the building blocks.
Enzymes are the manual workers that build our body from protein,
carbohydrates, and fats, just as construction workers build our homes.
You may have all the raw materials with which to build, but without the
workers (enzymes), you cannot even begin. What isn't commonly
understood is how important enzymes are to digestion an the concept of
to the late enzyme pioneer, Dr. Edward Howell, there are three
different types of enzymes: those that occur in our food, those that
are made in the body for the digestion of food, and the metabolic
enzymes produced by the body that are made to run the biochemical
reactions occurring in the body. Food enzymes are a natural part of
vegetables, fruits, grains, and other raw food. Food enzymes ripen
then slowly "digest" raw food. Even though food enzymes are important
they pose a problem to the food industry and must be removed from the
food supply in order to extend the shelf life of the food. Food
enzymes are destroyed or removed anytime the food is cooked, processed,
pasteurized, canned, packaged, or genetically engineered. Your body
needs these essential nutrients to aid in the digestive process so the
body does not have to produce all of the enzymes for the digestion of
are very specific to what they will break down or digest. Besides
moisture, they require three things to activate them: the proper
temperature, the proper pH (acid or alkaline), and the right substrate
(or material) to break down. For example, protease - the enzyme that
breaks down protein - will only work on protein, not carbohydrate.
What is the process of digestion? What happens to food when your body begins to digest it?
is largely taken for granted by just about everybody. You may assume
that what you put into your mouth is going to be digested, but
digestion doesn't just happen. Digestion is a complicated process that
is extremely important and should not be overlooked as as root cause of
many health problems. When digestion does not occur the way it should,
symptoms such as gas, bloating and pain may result.
normal digestion process begins in the mouth. While you chew food,
your salivary enzymes secrete digestive enzymes that begin to work
immediately. If raw food is eaten, the naturally occurring enzymes in
that food will also participate. If the food enzymes have been
denatured or destroyed through a food processing method, only the
enzymes in the saliva are available to begin digestion. When the food
is swallowed, it passes into the upper, or cardiac, part of the
stomach. During this time, the enzymes from the saliva and the food
begin to digest the food. Studies have shown that as much as 45% of
ingested carbohydrates can be digested in the first 15 minutes in the
stomach when only salivary amylase are at work. Supplementation with
plant enzymes, which work in a broad pH range, will increase the amount
of digestion that occurs in the stomach.
to popular belief, the stomach is flat and empty when one first begins
to eat. When the stomach receives the food, it begins to stretch,
which signals the production of the acid and enzymes needed for
digestion. This window of time, while the body creates and gathers
hydrochloric acid in the stomach takes at least 30 to 60 minutes.
Hydrochloric acid lowers the pH of the stomach to around 3.0, thus
activating the protein-digesting enzyme, pepsinogen, to its active
form, pepsin which initiates protein digestion. However, the food and
salivary enzymes become deactivated, not destroyed, in the acidic
environment of the stomach.
food coming from the stomach passes into the first part of the small
intestines called the duodenum. It is here that the liver and
gallbladder add bile to the mix, making the intestinal environment
alkaline. Bile does not contain enzymes and does no digestive work.
However, bile is responsible for degreasing food (emulsifying the fats)
so that the pancreatic enzymes can reach the food and complete
digestion. Pancreatic enzymes work in the small intestines and need an
alkaline environment in which to work. Based on the amount and type of
food you have eaten, the pancreas will produce only the amount of
enzymes needed to complete the digestive process. Supplementation with
plant enzymes will help digest your food, lessening the work of your
digestive system and relieving some of the stress on your digestive
organs. The digested food particles pass through the intestinal wall
to be assimilated by the body. The indigestible portions of the food,
such as insoluble fiber, are pushed into the colon for elimination.
one step of the digestive process does not happen, the subsequent
digestive actions are affected. For example, if you take antacids, you
are reducing your ability to produce hydrochloric acid and, therefore,
your ability to digest protein, which now has no way of being
thoroughly broken down. Protein digestion must begin in the acidic
environment of the stomach.
Why are pancreatic enzymes (pancreatin, chymotrpysin and trypsin) not used in many of the products that you use?
enzymes are animal enzymes that are only able to work in an alkaline
environment of 7.2 to 9.0. Therefore, pancreatic enzymes only work in
the duodenum of the small intestine. The do not enhance digestion of
food and thus do not spare the body the necessity of providing all the
enzymes needed to digest food. They find there best use in the
treatment of inflammatory problems.
Why is HCl (hydrochloric acid) not used in the products that you use?
in supplemental form, is actually a salt that is commonly used in
prescription and over-the-counter drugs as an ingredient carrier. True
hydrochloric acid is produced by the body to provide an acid
environment for the activation of pepsinogen to pepsin. Pepsin is what
breaks down protein into smaller fragments. True HCl is not available
as a supplement.
Why are betaine, papain, and bromelain not very effective in digestion?
is not a enzyme. During the digestive process, betaine donates
methionine (which contains sulfur) to the liver for the assimilation of
protein. Papain and bromelain are plant enzymes that have their peak
activity temperatures above body temperature. At body temperature,
bromelain and papain work at reduced efficacy. The plant enzymes in
the enzyme supplements that I use have their peak activity range
between 95 and 105 degrees Fahrenheit, well within body temperature.
How are food enzymes destroyed?
enzymes are destroyed by heat at temperatures of 118 degrees Fahrenheit
or higher. Canning, pasteurizing and microwaving all destroy enzymes
in food, thus increasing the body's demands for enzymes when digesting
processed or cooked foods.
What is acid-stable protease?
Acid-stable protease refers to protease that is stable or active in a pH range of 2.0 to 4.0.
What role does lactobacillus acidophilus have in digestion?
microorganisms produce lactic acid by digesting sugars and starches,
thereby producing an acid pH needed in the bowel. Acidophilus
microorganisms do not have any effect on the predigestion or digestion
of food and only work in the large intestine.
Why are whole herbs used in digestive products that you use?
are always additional benefits when using the whole plant instead of
chemical derivatives, as you will find in highly concentrated vitamin
and mineral supplements. The synergistic action that takes place with
the whole herb energized with the action of enzymes is remarkable. The
herbs used are biologically stable and proven effective.
Are food enzymes destroyed in the stomach?
Contrary to popular medical opinion, enzymes are not destroyed in the
stomach. Hydrochloric acid does not digest enzymes; its only function
is to activate the enzymes requiring an acid environment, such as
If I take enzymes, will my body stop producing enzymes?
Your body will not stop producing enzymes if you supplement your diet
with food enzymes. By supplementing with food enzymes, you are helping
to replace enzymes that are lost by the cooking or processing of food.
This relieves the body of its burden to create more digestive enzymes.
The body is then able to produce the required enzymes for other vital
How do I take enzymes supplements?
of the digestive supplements are formulated to be taken at the
beginning of the meal to aid the body in its digestive processes.
Others are meant to be taken after or between meals.
If I forget to take the digestive enzyme supplement at the beginning of a meal, can I take them afterwards?
you forget to take your digestive enzyme supplement at the beginning of
the meal, they can be taken during or immediately after the meal, as
soon as you remember. Taking an enzyme supplement at the beginning of
the meal is the most effective use of the supplement; however, taking
the enzyme supplements, formulated by Dr. Looms, during or after the
meal will still assist in the digestive process.
What do I do when I eat a big meal, like holiday dinner?
a larger than normal meal is being consumed, supplementing additional
capsules may be desired, depending on the amount of food being eaten,
If digestive problems persist, consult with an appropriate health care
What if I still have indigestion or feel bloated or overly full after my meal?
capsules can be used at your discretion. Regulating what you eat and
making wise food choices is suggested. Consult an appropriate health
care practitioner if symptoms persist; however, it is important to
match the supplemental enzyme formula to your diet.
What if I eat 5 to 6 meals per day?
By eating 5 to 6 times per day, you are probably eating smaller meals and only one capsule may be needed.
Should I take a digestive enzyme with a snack?
would be a good idea, especially if you are snacking on processed
foods. Processed foods have little to no enzyme content. Eating a
snack high in carbohydrates or white sugar may be just the time to take
a enzyme supplement.
Can I take the enzymes with my antacid or if my stomach is upset? Can I take enzymes if I have an ulcer?
you have a history of gastritis or ulcers, you may be sensitive to
products containing protease. Consumption of protease may cause
irritation in the stomach. If irritation occurs, drink lots of water
and discontinue use of the product. The stomach formula is suggested
as this does not contain any protease and includes ingredients that
traditionally have been used to nourish the mucosal lining of the
I am taking a prescription drug. Can I take an enzyme supplement with my prescription drug?
food enzyme supplements can be taken with prescription medications,
although consultation with your prescribing doctor or your pharmacist
is strongly suggested. If the prescription medication is taken at the
same time as the enzyme supplement, the absorption of the prescription
may increase, thus requiring a change in dosage of your prescription
medication only under your prescribing doctor's guidance. It is not
recommended to take enzymes at the same time as the prescription
drugs. Separate them by at least one hour.
How long will it take for me to notice results?
you are a unique individual, results will vary from what others may
experience. Most people notice a difference in digestive disturbances
and symptoms within a few days, if not within a few meals.
is potency measured or tested? How can I tell how concentrated the Loomis
enzyme supplement are? How can I compare these to other
products strengths? What is the difference?
manufacturers measure enzymes in FCC, PU, LU, USP, PC, HUT, CU, and so
on. Because enzyme supplementation is not yet regulated, enzymes do
not have a standard unit of measurement. Each enzyme supplement
company is able to choose an arbitrary unit of measure for their
product. The enzyme supplements formulated by Dr. Loomis are measured
in milligrams. Because of this, there is no way to compare one brand
to another for strength, potency, or concentration, unless it is done
by laboratory analysis. Potency of enzymes can only be tested in a
laboratory that is set up to do so. Furthermore, enzyme potency cannot
be tested if herbs or other plant material have been added, as the
added material can contain the same type of enzymes as are in the
product. Listing the "potency" of enzymes has become a marketing ploy
used by many supplement companies. Potency, however, has nothing to do
with results you obtain with enzymes. Potency must be matched to the
body's requirements. You will find that the enzyme supplements that I
use have been formulated by health care practitioners with clinical
experience to produce specific nutritional results.
are the enzymes used in the Loomis enzyme supplements any
different from other plant enzymes? What is the source of the enzymes?
plant enzymes that are used in the Loomis products are grown on microbes and
fungus such as Aspergillus, a genus of fungi that produces many
industrially useful enzymes, chemicals, and foods. Grown in a
controlled environment, Aspergillus oryzae and Aspergillus niger are
two of the many varieties of fungi used commercially. The enzymes are
vacuumed from one of the fungal varieties and purified, so that no
remnants of the fungus remains. Moreover, there should be no allergic
reactions to enzymes.
If I am allergic to mushroom/mold/yeast, won't I be allergic to these products?
has developed purification techniques that remove all but desired end
products: enzymes. Most people will not have any difficulties
associated with the use of products derived from fungus. However,
there may be a very few sensitive individuals who may experience
symptoms that they associate with exposure to mushrooms, mold, or
yeast. For those concerned about yeast, invertase is grown on
Saccaromyces cerevisiae, a type of yeast. However, the purification
process of this particular enzyme extracts all yeast residue.
What does the pH Balancing System (pHBS) mean?
trademark, pHBS, describes Dr. Loomis' formulas. The formulas have been
developed in a clinical setting and are based on years of clinical
observation, not just library information. Dr. Loomis' formulas have
been researched using not only patient signs an symptoms but clinical
findings as well. The pH Balancing System is your guarantee that Dr.
Loomis' supplements are perfectly pH balanced for nutrient
What is the shelf life of Dr. Loomis' enzyme supplement products?
life is approximately 3 years for most of the products, provided they
are not subjected to heat and excessive humidity. Each products will
be labeled with an expiration date and lot number. Store the bottle in
a cool, dry place with the lid tightly closed and keep away from
children. Enzymes will activate within the capsule if exposed to
moisture and warm temperatures. Also exposure to enzyme supplements to
electromagnetic fields or X-ray machines (such as found in airport
terminals) may reduce enzyme activity somewhat.
Can I give it to my dog or cat?
enzyme supplements can be given to dogs or cats. Before they eat, just
give them the capsule as you would any other supplement or open the
capsule and put its contents on their food.
Who are Loomis Institute graduates?
Institute Graduates are health care practitioners who have been trained
by Dr. Howard Loomis in the therapeutic use of food enzymes, enzyme
nutrition, and the Loomis System. Each graduate has the ability to
identify the reasons behind an individual's signs and symptoms, and
have been trained to use our products to support the specific needs of
