Nutrition Services

Everyone’s body is different, so we use advanced diagnostic testing first and foremost and consider lifestyle factors, age and patient history to create a customized plan for each one of our patients. Getting the right nutrition in you can mean something different for everyone. That is why many mass-market and fad diets fail, and indiscriminate consumption of dietary supplements, vitamins and nutrients may actually be harmful, depending on your personal health screening. A personalized approach is paramount to getting you on a path to good health, wellness and individual vitality.

Although most individuals can benefit from nutritional evaluation, traditional testing is highly inaccurate. LifeScape employs a pin-point precise technology developed by SpectraCell to provide far more reliable testing; permitting LifeScape’s physicians to more accurately evaluate vitamin, mineral, antioxidant, and essential fatty acid deficiencies and meticulously target nutritional interventions.


Brain chemicals, known as hormones and neurotransmitters, control many of the body’s functions. These chemicals can become depleted or unbalanced due to diet, stress, exposure to toxins, and genetics. This can result in excessive stress, mood disorders, anxiety, difficulty concentrating, focusing, or remembering, sleep difficulty, headaches, fatigue, low energy, weight gain, and food cravings. Utilizing a non-invasive lab test developed by NeuroScience, a world leader in neurotransmitter assessment, LifeScape physicians measure 13 different neurotransmitters and 11 different hormones. Then, through a course of individualized Targeted Amino Acid Therapy, correct imbalances in a carefully controlled sequence—offering relief to significant proportion of patients.


Identification of IgG delayed food allergies (as opposed to the standard IgE immediate food allergies) has been life changing for hundreds of LifeScape patients. Those with chronic sinus or ear infections, asthma, anxiety, chronic fatigue, migraine headaches, irritable bowel syndrome, arthritis, or eczema can often benefit significantly by eliminating certain foods from their diet. Utilizing a simple blood test, LifeScape providers can now identify intolerances to 115 foods as well as Candida yeast and systematically modify patients’ diets to moderate and often eliminate many chronic conditions.


While there are many nutritional programs out there, LifeScape vets out the science, technology and efficacy of each one before prescribing them to any patient. Our doctors and nutritionist may work with you on any number of customized programs for healthy diet, weight management, resolving dietary deficiencies or addressing inflammatory foods that may be leading to chronic conditions or illness. Remember, you’re never alone in your quest for a healthy, balanced diet and lifestyle. LifeScape’s staff is here to work with you and support you in your personalized goals and progress.

The powerful role nutrition plays in health is becoming increasingly clear. Unfortunately, the vitamin and supplement industries operate with surprisingly little oversight. Manufacture and marketing are largely unregulated. If you use an over-the-counter vitamin, mineral, or other nutritional supplements, there is a good chance that the label inaccurately reflects the product’s contents. You may not be receiving the intended health benefit, or you may even be causing yourself harm.

LifeScape has evaluated thousands of vitamins and supplements to find those produced with strong quality controls and that offer the best value. Product lines we carry and recommend, in the office and in our online store include:

NeuroScience – amino acid supplements for targeted repletion of neurotransmitters

Metagenics – wide variety of high quality supplements and medical foods to help with your nutritional needs

Pure Encapsulations – multivitamins, and an assorted array of supplements to meet your various needs.

Vital Remedy – Joint Formula, Antioxidant Formula and Statinguard protection for those who may need protection from statin drug induced nutrition depletion


Please don’t self-diagnose! Before changing any diet or nutritional routines, or taking any vitamins, minerals, nutraceuticals or dietary supplements – please consult your physician.

Many of our patients have seen dramatic success, and enjoyed visibly noticeable results by combining a custom weight management program with a regimen of medical aesthetics treatments.
