We are all exposed to multiple toxins from the environment; why does it only make some people sick? Often the answer is in their genomics, the minor alterations in genes that can determine our capacity to detox, for example.

I have been using genomic data for 16 years now, and while it does not explain everything, it is a valuable additional layer of information and understanding, which can help in selecting treatment modalities. For 3 years now the lab of choice has been excellent British start-up Lifecode. Their list of panels is updated frequently, and so far includes the key areas of Methylation, Detoxification, Oestrogen Balance, Histamine, Neurotransmitters, APOE, Thyroid Health, Nutrient Core and Athletic Performance.
