Dear Doctor,

     We have just completed some dramatic improvements in 
your NUTRI-SPEC analytical system of clinical nutrition.  
These changes give you three big advantages:

a.  The tests are easier and faster to perform.

b.  The test interpretation is much easier.

c.  Your analysis is much more specific -- more clearly     
    defining each patient's individual needs.

     This letter will summarize these exciting changes.


A.  Changes in the test procedures:

    1.  The following tests have been entirely deleted 
from your testing procedure:

        a.  The second of the three blood pressures.
        b.  The pilomotor reflex.
        c.  The Sargent's Line reflex.
        d.  The pupil reflex.

    2.  The following tests have been added:

        a.  An adjusted saliva pH
        b.  A fourth pulse

    3.  We have given you a new Test Results Form 
reflecting these changes in the test procedure.

    4.  Adjusted Saliva pH:

        a.  A chart is printed right on your Test Results   
    Form showing you how to convert your patient's saliva
                          - 2 -


    pH to the adjusted saliva pH.  You add to or subtract   
    from the saliva pH according to the patient's specific  
    gravity.  Enter the adjusted saliva pH next to         
    the saliva pH on the Test Results Form.

    5.  New Respiratory Rate, Blood Pressure and Pulse 
Procedure:

        a.  With the patient supine, and having already     
    taken the patient's saliva pH, measure the patient's    
    first pulse for 15 seconds, multiply by 4 and enter     
    on the Test Results Form.

            b.  Take the patient's respiratory rate for 30  
    seconds, multiply by 2 and enter on the Form.

        c.  Take the patient's first systolic and           
    diastolic blood pressures, and record.

        d.  With your watch or timer ready, ask the         
    patient to stand.  Begin timing as the patient's feet   
    hit the floor.  At the 5 second mark begin counting     
    your second pulse, counting seconds 5 through 20.  At   
    the 20 second mark immediately begin counting over      
    again to get the third pulse, counting from seconds 20  
    through 35.  You now have two numbers, for example, 16  
    and 18, representing the second and third pulses.       
    Multiply each by 4 and record on the Form.

        e.  With the patient continuing to stand, take the  
    second systolic and diastolic blood pressures and the   
    fourth pulse.  Record the blood pressures and           
    multiply by 4 to record your fourth pulse.

        f.  Have the patient sit, and test the breath hold

    6.  As before, the remaining tests (dermographics,      
cough and gag reflexes, and pupil size) may be performed 
either before or after the other tests.

    7.  The urine surface tension and multi stix 
procedures are unchanged.  (But be certain you are up to 
speed with the latest instructions for surface tension -- 
it remains your most important test.)

    8.  Though we have deleted the pupillary reflex as a 
test, the pupil size takes on additional significance in 
your testing procedure.  The pupil size has over the years 
demonstrated the highest correlation of all our tests with 
Sympathetic/Parasympathetic imbalances.

                          - 3 -


B.  Streamlining your test interpretation.

    1.  Interpreting your patients' test results has 
always been as simple as asking yourself five questions - 
one from each page of your Quick Reference Guide.  The 
procedure was fast and simple.  However, there was 
considerable room for the doctor's subjective 
interpretation of whether or not a particular imbalance 
existed in a patient.

    2.  We are now giving you an entirely revised Quick 
Reference Guide.  It follows the familiar format of each 
page representing the analysis of one of the five 
NUTRI-SPEC fundamental balance systems.  There are, 
however, these important improvements:

        a.  The top of each page gives you just a few       
    quick tests to determine whether this patient is a      
    likely candidate for the imbalance under                
    consideration.  In other words, if a 4-Point            
    Quick-Scan of your patient's tests does not reveal an   
    obvious tendency toward one imbalance or its opposite,  
    you need look no further -- just turn the page and      
    consider the next imbalance.

        b.  The ranges of abnormal results for each test    
    are much more specifically defined in this new Quick    
    Reference Guide.  This will eliminate any subjective    
    guess work on your part.

        c.  The supplement recommendations available for    
    you to give your patients have been greatly expanded.

        d.  The parameters indicating the need for each     
    supplement are very specifically defined.

    3.  This improved Quick Reference Guide analysis will 
assure that virtually any two NUTRI-SPEC doctors will  
come to precisely the same conclusion for any patient.


C.  Greater specificity in treating your patients.

    1.  The new test procedures, plus this more efficient   
analysis, will allow you to be even more specific, and 
thus more effective, in treating your patients.

    2.  You will find fewer ambiguous test patterns.  In 
other words, you will find less patients "on the border-
line" of an imbalance.  It will most usually either 
obviously be there or not.
                          - 4 -


    3.  You will find, in general, that you are treating 
fewer imbalances for each patient upon initial testing.

    4.  You will, however, find that new imbalances very 
frequently show up on subsequent testing.

        a.  But when these new imbalances show up they      
    will be quite obvious.

        b.  These imbalances will generally not show up     
    until the initial imbalances that you were treating     
    have improved dramatically.  (But this improvement may  
    come very quickly.)


        WHAT IS THE SPECIFIC RATIONALE BEHIND EACH
      OF THESE IMPROVEMENTS IN YOUR TEST PROCEDURE?

     Let us consider first the tests we have deleted from 
our system.  There isn't much to say about these tests 
other than that they do not meet our testing criteria of 
providing significant information about our patients with 
little time and energy invested.  The pilomotor reflex, 
Sargents line, and pupil reflex have failed over thousands 
upon thousands of patients (tested in my practice and 
yours) to consistently provide us valuable information.  
When these three tests "fit" they fit into a sympathetic 
or parasympathetic pattern that was already clearly 
obvious from our other tests.  When they did not fit, it 
was these tests that confused the clinical picture rather 
than bringing it into focus.  You've got better things to
do than stare at your patient's pupil for 30 seconds when 
the results of that test will be equivocal at best.

     These three tests now join the other tests in 
Appendix A of your book that are not part of our routine 
analysis.  Be aware that they exist -- because at times 
they are relevant, but use that information  only in the 
occasional instance when it is clinically significant.

     Let us talk now about the far more significant change 
in your procedure for orthostatic blood pressure and pulse 
challenge.  We have deleted one blood pressure and added 
one pulse.  Why?  Our procedure for challenging the 
immediate orthostatic blood pressure response simply was 
not working.  Why not?

     You may be interested to know that a normal 
orthostatic blood pressure response actually involves four 
changes in direction of the blood pressure within one 
minute.  The blood pressure goes from a steady state in
                          - 5 -


the supine position to a quick peak within a few seconds 
after standing, then plunges to a trough at about 10 
seconds after standing, then rises dramatically to a 
higher peak at 20 seconds, after which it gradually 
declines to the standing steady state which is reached at 
about one minute.

     We were attempting to measure the peak that ideally 
occurs at 20 seconds.  As you can well imagine, the 
slightest difference in timing between one staff member 
and another in your office, or between your office and 
some other Doctor's office would give an entirely 
different interpretation of a particular patient's 
orthostatic blood pressure response.

     This created a real dilemma for NUTRI-SPEC testing 
because the physiologic demands on the body when moving 
from a supine to a standing position are so perfectly 
correlated with several of your NUTRI-SPEC metabolic 
imbalances.  We hated to delete a test that was so 
important -- yet realized that having an inconsistent test 
was worse than no test at all.

     After studying hundreds and hundreds of test patterns 
we were very pleased to find that the pulse response 
actually gave us more information than we ever could have
obtained from the second blood pressure reading.

     Like the BP, the pulse also goes through several very 
rapid changes of direction upon moving from the supine to 
the standing position.  Your new procedure of counting the 
second pulse from seconds 5-20, and the third pulse from 
seconds 20-35, and then another after the steady state has 
been reached, enables you to nail down exactly by what 
means your patient attempts to adjust to the physiologic   
demands of the orthostatic challenge.

     Beginning in next month's Letter I will give you the 
specific rationale behind the adjusted saliva pH and 
explain how beautifully it now correlates with each of 
your NUTRI-SPEC fundamental imbalances.  I will also go 
page by page through the new Quick Reference Guide 
explaining what each of the exciting improvements means to 
you and your patients.  To obtain your copy of the new QRG  
just give us a call.  We will send one immediately, at no 
charge.  You need this now -- CALL TODAY.


     Let us close for this month by bringing you up to 
date on some of the most significant changes in your 
NUTRI-SPEC supplements.
                          - 6 -


1.  We have slashed the price of your electrolyte 
supplements from between $6.00 and $6.50 per bottle all 
the way down to $4.50.  (As NUTRI-SPEC grows we are able 
to buy in larger quantities at significant cost savings -- 
and we are delighted to pass the savings on to you.)

2.  Your Oxygenic A-Plus now contains GLUTATHIONE.  This 
is perhaps the most valuable nutrient in the whole 
Oxygenic A product.  I could go on for pages detailing the 
amazing biological activity of Glutathione.  For now 
suffice it to say that it is essential in the body as a 
carrier of oxygen, as a component of Glutathione reductase 
enzyme, and as part of Glutathione peroxidase.  We have 
wanted to supercharge Oxygenic A-Plus with glutathione for 
years.  We are ecstatic that we can finally give it to you

3.  We have added MAGNESIUM CHLORIDE to your product line.  
Magnesium Chloride will be a valuable component of your 
NUTRI-SPEC regimen for:

- certain electrolyte stress patients
- certain acidosis and alkalosis patients
- certain parasympathetic patients with asthma

4.  Finally, we are about to add six pure-form amino acids 
to your product line.  The potent biological activity of 
these amino acids will be described in the coming months 
as we detail the improvements in your Quick Reference 
Guide analysis.  The amino acids (which will be available 
some time later this month) include:

- L-Tyrosine         - Taurine        - L-Methionine
- L-Phenylalanine    - L-Glutamine    - L-Histidine


     This is an exciting time to be a part of NUTRI-SPEC.


                        Make It A Good Month,



                        Guy R. Schenker, D.C.
