Optimize your sports and mental performance with Comprehensive Nutritional Testing

To further support your performance, in addition to the physical and mental testing available for your game, we offer nutritional evaluations.
Improving your approach to nutrition is one of the most powerful methods of improving your performance during training sessions and maintaining progress over the long term.
The impact of deficiencies in nutrition can be seen in your energy levels, mental performance and ability to recover and heal from physical activity. All athletes at all ages can be hindered by gastric distress, poor absorption of nutrients and intestinal permeability.
Through nutritional testing, we are able to:
- Evaluate your levels of nutrient absorption.
- Review the genetic makeup of digestive organisms that may hinder performance.
- Create dietary recommendations that enhance both nutrient uptake and favorable gene expression.
These evaluations have been developed by Dr. Oscar Coetzee, who has worked with professional golfers for over two decades, holds multiple graduate degrees pertaining to nutrition and human performance and serves on the faculties of Georgetown Medical School, the University of Bridgeport and the Maryland University of Integrative Health.

Do you want to learn about why you struggle with fatigue, recovery, and injury?
Metabolomics Spotlight Testing

$191
Each functional wellness test contains everything necessary, including detailed instructions on how to noninvasively collect a urine sample and send it in for analysis. A report with the results contains a unique, in-depth assessment of many key areas of biochemistry and metabolism essential for human health, including the following:
Buy the test to learn more about…
- Your personal ability to utilize nutrients that contribute to your performance.
- Your personal ability to create energy from nutrients to preform at your highest level as well as recover from a hard work out quickly.
- Your personal ability to utilize Amino acids and protein, as well as how that contributes to your mood, anxiety and stress.
- Your personal inflammatory response and how that contributes to fatigue, recovery, catching cold frequently, and reoccurring injuries that are slow to recover.
- Your personal ability to detox, remove, and clear infections and other infectious and toxic materials.
- Personal test markers that show us why you are stressed, moody, and how we can support overall well-being and performance.
Do you want to learn about your digestion and nutrient absorption?
GI Spotlight Testing

$289
Each functional wellness test contains everything necessary, including detailed instructions, on how to noninvasively collect the sample and send it in for analysis. The resulting report contains a unique, comprehensive assessment into many of the key microbes that are essential for human physiology and overall wellness. This test will help provide insight in the following areas:
Buy the test to learn more about…
- Your personal ability to digest and absorb nutrients from your food.
- Your personal microbiome fingerprint and how we can optimize it to support overall health and performance.
- Athletes usually have very permeable guts (“leaky gut”) which contributes to fatigue, inability to recover, recurrent infections, and autoimmunity.
- Your personal digestive and nutrient absorption ability, as well as GI motility.
- Your personal inflammatory status and immune function in the gut to fight off infections and keep you at the top of your game.
Do you want to learn about how your genes impact your physiology and performance?
Genomic Spotlight Testing

$207
Genomic Spotlight test identifies how the function of your genes or SNPs impacts your physiology and ultimately your performance. Using this test, we can customize a personalized protocol based on your individual genomic data in “real-time” providing relevant personalized information on nutritional supplements, diet, and lifestyle changes that can influence your gene expression, function, and ultimately your performance, health, and well-being. This is a test you only have to do once. It shows us the potholes in the road (your genes) and how we can fill those potholes nutritionally to support the best possible expression of your genes.

Dr. Coetzee
Dr. Oscar Coetzee
Psychonutrigenomics is a new field of study in functional medicine developed and evolved by Dr. Oscar Coetzee. Dr. Coetzee has worked with professional golfers for decades on the mental side, focusing on specific personality traits, and developing his own personality assessment questionnaire to assess these criteria. Dr. Coetzee played junior and amateur golf with Ernie Els and Retief Goosen in his native South Africa. He played collegiate golf at the University of Pretoria in South Africa and had various victories as an amateur and junior. Dr. Coetzee continued his education in the USA, finishing graduate degrees in psychology, human nutrition, holistic nutrition, and clinical nutrition. His doctoral work focused on functional nutritional medicine with specializations in nutritional genomics and metabolics. He started his professional career at Fair Oaks Hospital working for the Psychiatric Institutes of America in clinical co-dependency counseling and suicide intervention. From there he evolved into sports psychology, organizational psychology, and now the nutritional/psychological overlap. Dr. Coetzee is currently the clinical director of Natural Healthcare Center, working in areas of metabolic-related disease, behavioral disorders, and gastrointestinal dysbiosis. He is a ranked faculty member at the Georgetown University Medical School, University of Bridgeport, and Maryland University of Integrative Health.

Danielle can help you understand the relationship between nutrition and overall health so you can make informed dietary choices that prevent disease and improve your quality of life. When Danielle’s husband lost 80 percent of his eyesight in a matter of minutes and was diagnosed with multiple sclerosis, doctors couldn’t explain why medication would stop his body from attacking itself. They decided to focus on diet and exercise to combat the disease and both went back to school to better understand physiology, biochemistry, and nutrition as a healing modality. Danielle learned how nutritional interventions and lifestyle change positively influenced his conditions and overall vitality. This experience ignited her passion for the field of nutrition and sparked a strong desire to help others achieve similar results. Danielle’s educational journey opened her eyes to the profound impact that nutrients can have on physiological processes, and the complex interplay between diet, metabolism, and disease prevention.
