Dear Doctor,

     Last month we started your New Year off with exciting 
news of major improvements in your NUTRI-SPEC testing 
system.  You were given:

- New testing procedures -- even faster and easier to       
  employ.

- A new Test Results Form to accommodate the improved test  
  procedures.

- A totally revised Quick Reference Guide upon which to     
  base your test interpretation.

- Dramatic price cuts in all your electrolyte supplements.

- The addition of Glutathione -- with it's amazing high     
  biological activity -- to your Oxygenic A.

- The introduction of seven entirely new products           
  including magnesium chloride as well as six pure form     
  amino acids.

     I've got so much more to tell you I don't know where 
to begin.

     In the last Letter you learned the step by step 
procedure for all the revised tests.  You also came to 
understand why it was essential that we changed the way 
you test your patient's response to orthostatic challenge.  
The new blood pressures and pulses give you a wealth of 
information that you just were not consistently getting 
before.  As an added bonus -- the new blood pressure and 
pulse testing is easier and faster than the old.

     This month I absolutely must share with you the story 
behind your new adjusted saliva pH.  Beyond that, it is 
difficult to prioritize the material I want to give you -- 
because it is all so critically important.  You need a 
detailed explanation of every page of your Quick Reference 
Guide.  You also want the complete scoop on the seven 
powerful new supplements at your disposal.

     I suspect the most meaningful way for you to ingest 
all the new material is to have it presented page by page 
of the new Quick Reference Guide.  I'll describe the 
biological activity of each of the new supplements as they 
come up in the discussion of your Quick Reference Guide 
changes.                                                   

     It will, of course, take us several months to put all 
the material out in front of you such that you develop a 
complete working knowledge of this quantum leap in power 
and specificity of your NUTRI-SPEC analysis.  That does 
not mean, however, that you cannot begin offering this 
phenomenal service to your patients immediately -- even 
without a complete grasp of the theory behind it.  You 
should have the procedures down pat.  (If you don't, 
mastery of the procedures is only a phone call away -- 
call us.)

     There is also no reason why you can't call for 
explanation of a portion of your analysis, or an 
explanation of the rationale behind the use of one of the 
new products.  Call us for as detailed an explanation as 
you want.  In other words, if you test a patient tomorrow 
and find a metabolic acidosis and the need for the amino 
acid Glutamine for that patient -- you need not wait for a 
month or two for me to get around to explaining the 
rationale for the use of Glutamine for an acidosis.  Feel 
free to jump the gun and call with any questions you have. 


                  ADJUSTED SALIVA pH --
             FINALLY, A SALIVA pH THAT FITS.

     The A-SpH is the most significant improvement in your 
analytical system in many years.  For me personally it is 
a source of both excitement and embarrassment.  Exciting   
because of how beautifully it clarifies the analysis of so 
many patients -- yet embarrassing because it took me 18 
years to figure it out.

     When I first began developing the NUTRI-SPEC testing 
system I knew that the saliva pH would provide a wealth of 
information and be one of our most significant tools of
                          - 3 -


analysis.  I also knew that there were two major 
determinants of saliva pH:

- the electrolyte content of the saliva
- the carbon dioxide plus carbonic acid level of the 
saliva.

I knew precisely how (theoretically) the saliva pH should 
fit into each of our fundamental balance systems.

     By 1984, when NUTRI-SPEC had evolved to the point 
that it could legitimately be called a clinical testing 
system, the saliva pH had already become a source of 
frustration.  It just did not consistently do what it was 
supposed to do.  By 1989 when we put out the first edition  
of "An Analytical System of Clinical Nutrition," the 
saliva pH was relegated to third class status as a 
clinical indicator.  I couldn't get myself to delete it 
completely because I knew that the saliva pH did respond 
to aberrations in metabolic balance.  Some day, I thought, 
I'll make some sense out of its seemingly random ups and 
downs.

     Several months ago I had an "Aha, you dummy, why 
didn't you see this years ago" experience.  I was actually 
working on improvements in our analysis of electrolyte 
insufficiency patients -- studying the electrolyte content 
of the saliva from dozens of analyses we did years ago.  I 
saw clearly that in many patients the saliva pH was higher 
in patients with low saliva electrolyte content and the 
saliva pH was lower in patients with high saliva 
electrolytes.  No big surprise here, as I already knew 
that electrolyte content was one of the two prime movers 
of saliva pH.

     Since, however, there were patients whose saliva pH 
was either very high or very low despite relatively normal 
electrolyte concentrations, it occurred to me that these 
must be the people whose saliva pH was primarily 
influenced by its CO2 plus carbonic acid content.  The 
obvious thing to do was to divide this large group of 
patients under study into two groups -- one whose saliva 
pH was electrolyte dependent, and one whose saliva pH was 
influenced primarily by CO2 plus H2CO3.

     Nice idea, but it didn't work because such a high 
percentage of the patients whose saliva pH was influenced 
by electrolytes also had NUTRI-SPEC imbalances that would 
cause abnormal CO2 plus H2CO3 levels.  In other words, 
there was no easily identified factor or factors that 
distinguished one saliva pH group from another.
                          - 4 -


     Then, I said, "Hey, look at this."

               I HAD DISCOVERED A PATTERN.

     All the patients whose saliva pH was either
high or low in association with low or high electrolyte 
levels (whether or not the saliva pH and electrolyte 
levels were the result of an electrolyte imbalance or some 
other NUTRI-SPEC imbalance) had a urinary specific gravity 
that varied inversely with the saliva pH.  Every patient 
who had a high saliva pH with low saliva electrolytes had 
a low urine specific gravity.  Every patient who had an 
acid saliva pH with high electrolyte concentration had a 
high urine specific gravity.

     Eureka!  For years I had known that saliva pH was 
dependent upon electrolyte concentration without stopping 
to consider that electrolyte concentration is just the 
inverse of water concentration.  All I had to do was find 
a way to factor in this urine specific gravity association 
with saliva pH and I would have effectively segregated the 
two major influences on saliva pH.  That is to say I could 
come up with an adjusted saliva pH that would reflect 
almost purely the carbon dioxide plus carbonic acid 
influence on saliva pH.  These organic acids are, of 
course, the key to the saliva pH's association with 
Anaerobic/Dysaerobic Imbalances, Glucogenic/Ketogenic 
Imbalances, and Acid/Alkaline imbalances.

     Having contrived this A-SpH, I was overwhelmed by its 
power as an analytical tool.  Suddenly the saliva pH was 
elevated to its rightful status as a primary indicator in 
our system.  We now began finding almost all anaerobic 
patients and glucogenic patients had low A-SpH.  Almost 
all dysaerobic and ketogenic patients had elevated A-SpH.  
The saliva pH's you consider for acid/alkaline imbalance 
suddenly started to conform to the expected pattern.

     This happy story about saliva pH and how it is now an 
important part of your analysis for every one of your five 
imbalances leads us right into our discussion of your new 
Quick Reference Guide interpretation.  Let us begin with a 
look at your new QRG analysis of Electrolyte Stress and 
Electrolyte Insufficiency.

     The first thing you will notice at the top of this 
page (and at the top of each page of your new QRG) is a 
list of a few tests designated as a "Quick Scan."  The 
point of these Quick Scans is simply this:  if one of the  
imbalances under consideration on this page is not showing
a clear dominance over it's opposite imbalance, then you
                          - 5 -


need look no further -- just turn the page and consider 
the next imbalance.

     In the case of Electrolyte Stress and Electrolyte
Insufficiency the 4 tests of your Quick Scan are really 
the only four tests you need consider at all.

     The trick to doing your Quick Reference Guide 
analysis in just a minute or two is to learn to pull this 
small group of numbers off the Test Results Form and carry 
it to the Quick Reference Guide AS A GROUP.  In other 
words, do not bother your eyes with four time-consuming 
trips back and forth between your patient's test results 
and the Quick Reference Guide page.

- Know which numbers you are looking for;                   
- Read them into your brain;                               
- Then carry them over to the Quick Reference Guide and     
  see if they fit into one of the two patterns.

     For Electrolyte Stress and Electrolyte Insufficiency 
the 4-Point Quick Scan consists of:

a)  The first pulse subtracted from the highest of the      
    four pulses.

b)  The second diastolic blood pressure.

c)  The first systolic blood pressure.

d)  The first pulse.

     You can scan for these quite easily as they are all 
in a small counterclockwise circle in the middle of your 
Test Results Form.

     With these four numbers you will know in less than 5 
seconds whether the patient has an Electrolyte Stress or 
an Electrolyte Insufficiency.  If there is no apparent 
imbalance you simply turn the page.  If your patient's 
four tests do conform to either pattern, then simply look 
below on the QRG page to determine what supplements are 
specifically indicated for this patient.

     Note at the bottom of both the Electrolyte Stress and 
the Electrolyte Insufficiency column you are given a 
criterion upon which to determine your patients' water 
intake.  This is a neat little formula using the saliva pH 
(not the A-SpH) and the specific gravity.  I'll give an
example to illustrate.  You have a patient with a saliva 
pH of 6.8 and a specific gravity of 25.  6.8 - 2.5 = 4.3.
                          - 6 -


4.3 is less than 5, so the patient needs to increase his 
water intake.  Another example.  Your patient has a saliva 
pH of 6.8 and a specific gravity of 10.  6.8 - 1.0 = 5.8.  
5.8 is more than 5, so the patient's water intake is 
adequate (and this may even be the case in a patient you
are treating for Electrolyte Stress.)

     The list of potential supplements for your patients 
with Electrolyte Stress or Electrolyte Insufficiency has 
been greatly expanded.  Notice, I said potential 
supplements.  From this expanded list you will pick and 
choose just those few supplements which will have the 
desired metabolic impact on each of your patients.

     Even more specificity equates to an amazing increase 
in biological activity.

     With the old protocol for correcting Electrolyte 
Stress imbalances we have seen countless "miracles."  
There are your patients who, having been on blood pressure 
medication for years, were able to get off the drugs 
entirely.  There are those with claudication who can now 
walk like they could years ago.  There are those for whom  
angina pain is, thanks to NUTRI-SPEC, a thing of the past.

     Still -- there have been those Electrolyte Stress 
patients in whose case we quickly reached a plateau.  The 
same can be said for far too many Electrolyte Insuf-      
fiency patients.  We just did not have the big guns to 
push them out of their metabolic rut.

     Just wait until you see what happens with the use of 
your amino acids and other nutrients when used according
to objective indicators.


                        Sincerely,



                        Guy R. Schenker, D.C.


P.S.  The new Formula ES will not be available for many 
more weeks.  Even without it you are going to stop 
cardiovascular disease in its tracks.
