Functional Blood Chemistry Analysis is a tailor-made preventative nutritional regimen based on your unique nutritional needs. When blood testing is done, there is a range called the 'lab range' that your results are usually tested against. The problem with this range is if you are outside it, you are already in the 'sickness' or 'disease' range. Functional blood chemistry analysis uses a range called the 'functional range' which is a narrower range that leans towards health and homeostasis within the body. If you are outside this range, you may or may not be having symptoms, but it is an indicator that you are heading towards 'disease'. By working with natural supplementation specific to your results, you are taking a preventative approach with your health and working on keeping balance and health in your body.
