What does RXN stand for?  

RXN is shorthand for "reäction" in medical terminology, so the company name is pronounced "Gut Reäction Nutrition."  The reason behind the term is instinct- you know food affects how you feel.  You know food is causing you an issue.  You know you need to do something about it.  If you're reading this, you've already taken the first step.  Keep going.   

Rather than meet in-person, can we work remotely?

Sure!  All sessions are conducted virtually either by phone or telehealth, depending on your preference. No need to meet in-person!  For telehealth, there are no programs to download.


What is the difference between Mediator Release Testing (MRT) and IgG testing?  Many tests seem to use IgG as an indicator of food sensitivities.  Which is better? 

Hands down, MRT is the preferred method of detecting and identifying food sensitivities.  Though all tests have their limitations, MRT outperforms IgG testing in five key ways: 

  • IgG is not able to test for food chemicals- MRT is

  • IgG is limited to Type III Hypersensitivity reactions- MRT not only tests for Type III, but also Type IV Hypersensitivities (Food Sensitivities take both pathways, not just one)

  • High levels of IgG can either be protective of your immune system or destructive of it, the test has no way of differentiating- MRT doesn't have this problem because it is not an IgG based test

  • IgG only tests for IgG, even though IgM, Complement, T-cells and others can be involved in food sensitivity reactions- MRT tests for ALL released mediators regardless of which mechanism is triggered

  • There is no specific diet protocol to follow once your IgG results come in- MRT has the LEAP diet protocol

For more on why IgG is not useful, please read this article.

It is for these reasons I believe MRT is superior to IgG testing.  Let's not waste time- you have a life to live.


Most blood tests look at red blood cells but the test you use analyzes white blood cells. What is the benefit of doing so?  

Testing white blood cells is a better way to see your long-term nutritional status.  Red blood cells have an average lifespan of about 3 months whereas white blood cells have an average life span of about 6 months.  Think of your white blood cells as a full-length film and your red blood cells as a scene in that film.  Wouldn't you rather watch the whole movie...especially when you're the star? 

I noticed that iron isn't tested.  Why is that?

Iron attaches to the red blood cell (giving it that deep red color), so testing the white blood cell would be silly!  


Is genetic testing considered diagnostic?  

No, nutrigenomic testing is not considered diagnostic.  Though you may carry genes that affect how you metabolize and absorb nutrients, it does not necessarily mean that you currently have any condition.  

Nutrigenomic testing provides your risk of health complications based on any genetic mutations you have, compared to the general population without those mutations. 

If nutrigenomic testing isn't diagnostic, what's the point of it? 

The point of nutrigenomic testing is to identify mutations in your DNA that prevent you from fully metabolizing and/or absorbing nutrients, which increases your odds for disease. For instance, if it's discovered that you have a risk variant for caffeine (either the GA or AA genotype), your risk of cardiovascular disease is 53% higher when caffeine consumption is excessive (over 200 mg per day) as opposed to those without a risk variant.  If caffeine consumption is limited to 200 mg per day or less, your risk of cardiovascular disease is decreased by 53%.  Knowing this information can help you to make better dietary choices so you can lead a longer, more productive, healthier life. The test itself will not tell you whether or not you have cardiovascular disease.      


What determines metabolic rate?

Your metabolism is based on a number of factors.  The most common ones are:

  • Body size – Larger frames tend to have higher metabolisms

  • Body composition – Individuals with greater muscle mass burn more calories

  • Age – Metabolism slows down as we age

  • Sex – Men typically have a faster metabolism than women of the same age and weight

  • Health and medical conditions – Stress, medications, pregnancy and hormonal disorders (such as hypothyroidism) can change metabolic requirements

  • Genetics – Thank your parents

Can’t you estimate my metabolism?

Metabolic equations like Harris-Benedict, Mifflin-St. Jeor and kcals/kg are estimations only and do not take into consideration your genetic makeup and medical conditions.  Without this information, the results are inaccurate. 

How does the test work? 

The test measures your metabolism using indirect calorimetry. 

Indirect calorimetry is the gold standard when it comes to metabolic testing and is considered highly accurate.  It measures oxygen consumption and carbon dioxide production, allowing us to determine how much energy your body requires.   

Is the test invasive?

No, the test is non-invasive and only takes 30 minutes to complete (subsequent tests take 15 minutes).  All you need to do is wear a nose clip while breathing into a tube that’s connected to a portable device- that’s it!      

Is fasting required? 

Yes, you must fast for at least 8 hours in order for the results to be accurate.  This must be done first thing in the morning around the time you normally wake up.  Arrive relaxed and well rested. 

Can my metabolism change?

Absolutely!  Your metabolism fluctuates depending on how active you are and how much weight you’ve lost or gained.  If your weight loss has plateaued, it’s likely that your metabolism how slowed down in response, so re-testing is a good idea. 


What kind of workplace wellness services do you offer?

That depends on what you’re looking for.  Once you’ve determined your goals for a workplace wellness program, I’ll recommend the services that I feel align with those goals.  

How long do your workplace wellness programs last?

As long as you’d like them to.  There’s no minimum and there’s definitely no maximum.  Each company has different needs. 

What methods of payment do you accept?

Check is preferred but I also accept all major credit cards.
