DNA Testing

Lifecode Gx® offers a range of specialist nutrigenomics DNA test panels which inform how health risks can be mitigated through personalised nutrition and lifestyle change.

If you are struggling with weight loss, stress management, mood swings, hormonal imbalance, nutrient deficiencies, fatigue or other health issues, your DNA can provide targeted information to help guide you on the right nutrient and lifestyle path.

Maybe your genetic variation means that you require additional Vitamin D or Vitamin A? Maybe you have a gene variation that affects the way you metabolise fat so the Keto diet is definitely not for you? Maybe you metabolise caffeine slowly which is why you struggle sleeping? Maybe you are lactose intolerant? 
These panels include only well-researched gene variations which can be supported through nutrition and lifestyle..

Simply take a cheek swab and choose the relevant panel; Oestrogen Balance, Thyroid Balance, Nutrient core, Nervous system, Methylation, Detoxification, Histamine intolerance or Athlete.

Price: 177CHF* per panel plus 1hr consultation to explain results.

* plus 120chf for the test kit



Client testimonial:


"I recently sought out Gill's help having suffered several bouts of urinary tract infections. The antibiotics prescribed by the doctor had not always successfully treated the infections & I was therefore desperate to find a prophylactic solution to deter further infections occurring. Thanks to Gill's expert knowledge on imbalances in the body, she successfully helped me to prevent further infections by suggesting dietary changes as well as recommending a probiotic & herbal supplement to inhibit bacterial growth. I am so very grateful!"

DUTCH  complete hormone test by Precision Analytical :

This dried urine test can help identify the root causes of hormone imbalances in men and women. It can provide insights into conditions such as the menopause, PCOS, weight gain, fatigue, low libido, premenstrual syndrome, mood swings, sleep issues, mood disorders and prostate issues in men. Additionally, the test can be used to gather baseline measurements for the administration and monitoring of hormone replacement therapy.
The DUTCH test is simple and easy to use. Urine samples are taken using filter paper collection strips without the need for a blood draw or 24-hour urine collection.

Price: 480CHF including the test and a 1hr consultation to explain the results.
