How well does your body transport oxygen from your lungs to your muscles? Does it digest proteins and utilize carbohydrates as effectively as it should? Has your athletic performance started to decline? Do you frequently feel fatigued or have difficulty recovering from physical or mental stress?    
 
Posing any one of these questions to your doctor might get you a standard, serum chemistry profile as a general screen to rule out disease.  And while insights from this type of laboratory testing can be helpful, they don’t provide any direct or relevant information about the basic, physiological processes that drive your potential for health. 
 
At Core 4 Nutrition, determining the connection between your biological well-being and your functional performance capacity is our specialty.  Through the use of a series of unique assessments—all performed at home with a simple finger stick, saliva, or urine sample—it’s possible to identify and restore your body’s most essential nutrient needs.
 
I have been asked a number of times, “What’s so special about the Core 4 assessments? Can’t I just do a few extra tests the next time I go to my doctor?”  

There are a number of practical reasons why going to your doctor will not provide you with the information—or plan of action—that you need. 
 
First and foremost, the Core 4 assessments are sourced from independent, specialty laboratories that are not considered “standard” within the realm of traditional medicine. Not only are these assessments unavailable to most physicians, few are educated enough to even interpret their results. Evaluating the cellular health and performance needs of a fit, healthy, and motivated person is something that most doctors do not have the time, inclination, or experience to do....

If you're a dedicated athlete who works hard to become fitter, faster and stronger, it's important to realize that solid and lasting performance gains need to happen from the "inside out."  While external performance analysis—V02 max and lactate threshold tests—can be useful, they don’t provide any useful insight into the physiological processes at work inside an athlete’s body; into the internal mechanisms responsible for those hard-earned, end results.

Ask yourself the following questions:

How well does your body transport oxygen from the lungs to your muscles?  Does it digest proteins and utilize carbohydrates as effectively as it should?
Has your performance started to decline or hit an immovable plateau? Do you have difficulty recovering after a hard effort?  What is your body trying to tell you?

There’s no need to guess.  Measuring and evaluating your body’s physiological performance potential can be done easily and inexpensively, in the comfort and convenience of your own home, with the series of laboratory-based assessments made available by Core 4 Nutrition....
