Spring is on
its way here in the beautiful Ozark
Mountains of Arkansas! Along with warmer
jonquils, and baby calves, Spring also means that
several large conferences are near. Dr. Devin
owner of Houston Nutraceuticals, will be speaking at
several important conferences in the coming months.
Information and details are provided below.
We at HNI want you to know that this forum is here as
a resource for information on enzymes and other
nutritional issues. What would YOU like to see

CHEWABLE AFP PEPTIZYDE AVAILABLE IN MARCH!
Many parents know the frustration of trying to get a
child to swallow a capsule. Chewable tablets have
been a good
alternative for those children, and many of our
customers have asked if our enzymes could be
tableted. We are pleased to answer, "YES!". AFP
Peptizyde will be available sometime in March as a
fruit-flavored soft tablet.
From a manufacturing viewpoint, tableting is very
different from encapsulating a powdered product,
usually requiring high pressure to bind the material
into a solid tablet. According to Dr. Devin Houston,
the pressures involved in forming the tablet can
generate heat, which may destroy the enzyme activity.
"I had initially been resistant to tableting our products
due to concerns about loss of enzyme
activity. However, we found a manufacturer that uses
the latest state-of-the-art processes for producing a
soft tablet with no loss of enzyme potency."
Dr. Houston notes that it is not possible to get as
much enzyme into a tablet as is found in a capsule, so
the enzyme load per tablet will be smaller compared
to capsules. But many parents divide the capsule
doses, so the AFP Peptizyde may be better for those
situations. Also, one can simply take more tablets to
get the desired dosage.
For the present, only AFP Peptizyde is offered in
tableted form. However, if the demand for Chewable
AFP is good, HNI's other products will also follow suit.

||G'DAY, MATE! DR. HOUSTON SPEAKING IN AUSTRALIA!
Dr. Devin Houston, the scientist behind many of the
enzyme formulations you see on the market, will be
speaking at the Autism Behavioral Intervention
Queensland (ABIQ) Conference in Brisbane, Australia
on Saturday, May 15, 2004. He is currently scheduled
for the 3:30 - 5:00 pm timeslot. For more information
about the ABIQ 2004 conference, CLICK
Dr. Houston and his wife, Trish, will be traveling
throughout Australia and New Zealand from May 9th
through May 24th. Cities on the itinerary include
Sydney, Brisbane, Cairns in Australia and Queenstown,
Christchurch, and Rotorua in New Zealand. The
Houstons are very excited about visiting the "land
down under" and the chance to meet some of their
||AUTISM ONE IN CHICAGO
Mark your calendars for May 27th - 30th in Chicago to
attend the newest and most exciting conference
concerning help for children with autism. Dr. Houston
will be speaking in the biomedical interventions track
of the conference, as well as exhibiting enzyme
products. For more information on Autism One, CLICK HERE.
For several years, Dr. Houston has been willing to
speak with parent groups concerning such topics as
nutrition, how dietary enzymes work, and other topics
of interest. The Autism One conference will be a
chance for parents to hear and see Dr. Houston's
presentation on how enzymes affect digestion. We
hope those HNI customers who attend will be able to
come by our booth and visit.
||ENZYME SPOTLIGHT:DPP IV PEPTIDASE
This issue's featured enzyme is DPP IV
Peptidase. The term "peptidase" actually refers
to a large and diverse category of proteolytic enzymes
that remove amino acids from proteins in groups of
two or more. DPP IV (dipeptidyl peptidase 4) is a
protease that removes X--Pro from one end of a
protein chain, where "X" represents any amino acid
and "Pro" refers to the amino acid proline. DPP IV is
the subject of much research in a number of different
biomedical forums, and may be an important regulator
of certain cellular functions.
DPP IV is available commercially in purified form, but
in dietary enzyme supplements, it is found as an
additional enzyme activity in other fungal enzyme
preparations. For example, the enzyme blend
standardized on lactase activity and sold as "Lactase"
may have additional enzymes present at varying
levels, including DPP IV. Presently, enzyme product
manufacturers do not sell DPP IV as such, but they
have ascertained which of their stock enzyme
preparations do have DPP IV activity, and that is what
is put into most enzyme products. It is misleading to
put the term "DPP IV Peptidase" on a product label,
because the activity units assigned to Peptidase
actually reflect the total proteolytic activity of the
enzyme blend, not the specific activity of DPP IV. It is
more appropriate to label the enzyme as "Peptidase
(with DPP IV)".
DPP IV is the only known enzyme to break down
casomorphin, the exorphin peptide derived from
casein. Research indicates that the enzyme removes
at least 2 sets of dipeptide amino acids, or 4 amino
acids, which disrupts the structure of casomorphin,
essentially inactivating the peptide.
DPP IV may be helpful for those with intolerances to
exorphins derived from casein and gluten. DPP IV has
only one very specific action, and for it to be effective
dietary interventions, it should be accompanied by
several other less specific proteases that "cut" proteins
in a different manner from DPP IV.
||HELP!! I CAN'T ORDER ONLINE!!
We've heard that phrase many times! Many of our
customers are frustrated that the HNI online order
system apparently doesn't work for them. Conversely,
we at HNI have also been
frustrated because we could never find a reason for
why the system works for so many, but not for others.
Until now, that is! We have just obtained information
that a security update to Microsoft's Internet Explorer
may be the cause of the problem. In short, the update
was not allowing a valid connection to certain Web
servers, including those used by Miva Merchant, our
online order gateway.
To fix the problem, you may need to download a
for Explorer from Microsoft. You can obtain the
download by clicking HERE.
We prefer our customers to use the online ordering
system if at all possible, as it allows us to process
orders more efficiently. But the important thing is that
you do order, so if online ordering is not your thing,
please call our toll-free number, if we don't answer
right away, please leave your information on our
protected voice mail system, or fax your order to 479-
549-4536. All ordering methods are secured and

||WHAT'S THE BEST WAY TO CONTACT DR. HOUSTON?
Education and information is an important part of what
we do at HNI. Our staff will try their best to answer
any question you may have, but the scientific/technical
expert is "Dr. Devin", and he is happy to help you with
The best way to reach Dr. Houston is through email, as
this gives him a chance to research your question, if
Due to the volume of emails received, it may take
awhile to receive an answer, but most emails are
answered within 1 to 2 days. When on the road, Dr.
Houston can usually access his emails. Calling by
phone is fine, but please understand we only have two
phone lines, and often they are busy due to the heavy
volume of ordering. Please feel free to leave a
