Genetic Analysis

Understanding genetic data enables us to make changes that directly influence how your genes play out, enhance longevity, maximise energy, and ensure weight control. Personalised nutritional recommendations can be based on your genetics.

Nutrigenomics identifies how our genes interact with our foods and supplement intake. It’s the most advanced nutritional programme available and completely tailored to you.

We use both advanced genetic testing as well as functional testing to fully understand your body's genetic status and function in order to tailor your nutrition, lifestyle, and supplement programme.

Therefore, our genetic analysis involves not only a saliva sample to test your genes, but also comprehensive functional testing to achieve the above.

We analyse the data and create a bespoke programme tailored to you by taking the following into account:

Your medical history
popular tests icons2-09
Your health & wellness goals
popular tests icons2-10
Your lifestyle

Genetic testing can show susceptibility to disease risk, however we don’t focus on that because disease risk markers aren’t a guarantee for illness. Your programme will be tailored according to your results to ensure maximum benefit.

Worldwide testing services available

Functional tests can be sent to wherever you are in the world for your convenience.

Packages are available and can be customised for you.
