Specialty genetic or nutrient testing might be ordered to evaluate your bodies ability to use nutrients from foods, and to evaluate how your DNA may affect your mood and health. DNA testing uses a mouth swab in your own home or right here in our office! Your genetic information is evaluated in conjunction with your own unique story, experiences and environmental factors to help guide treatment decisions, and possibly even determine why you are vulnerable to certain symptoms, and what medication, or nutritional supplements, might be the best option for you.
