Work with Tanya Borowski, Functional Nutritionist

Achieve your optimal health potential with a Certified Functional Medicine Practitioner

Tanya Borowski, Certified Practitioner

Becoming a client of Nutritional Values

Tanya has trained extensively in Functional Medicine and is one of only 12 fully certified practitioners in the UK. Functional Medicine is a holistic and science-led approach which treats each person individually, focusing on the underlying factors that are causing and fueling your symptoms or condition. The guiding principle is getting to the root cause of health issues and thereby restore the body to optimal health and wellness.

The way that Tanya works with clients differs considerably from the conventional model so please do read the following information thoroughly to familiarise yourself with the process.

Somewhat like a health detective, Tanya will gather clues from your past, conduct thorough testing and scientific research to unlock your true vitality. The key to this is the development of a personalised 360° Health Treatment Plan which includes nutrition advice, botanical medicines, supplements, specialised dietary programs such as gut healing, weight-loss or tailored elimination diets, stress-management techniques and exercise advice. In Functional Medicine, there’s no one-size-fits-all treatment so even if you and a friend have the same symptoms or condition you won’t get the same treatment plan because your journeys have been entirely different and unique.

Finding root causes, conducting testing, researching and connecting all the dots to best optimise your health, it takes time. In this type of work Tanya cannot truly help you in one to two sessions. It’s rather like committing to increase your fitness to run a marathon; a one off session at the gym or going to a class every once in while isn’t going to achieve your goal of completing that marathon. After years practicing in this way Tanya has a sense of how much time it may take to facilitate healing. Plan on a minimum of 5 months and for others it may be a longer process. It’s a commitment from both of you. You can read some testimonials from Tanya’s previous clients here.

Summer 2017 update:
I am currently booked for new client appointments and will be taking sometime during July and August away from my clinic to research, attended further advanced training as well as spending some overdue quality time with my family. I will of course be supporting my existing clients throughout this period, within clinic hours.

If you have a new enquiry, please could you please Submit the Appointment Request Form in step one and if we are able to help, we can make a booking for you.

We have now filled new appointments from September - December from an existing waiting list, so bookings are being offered from January 2018.

There are some exciting resources coming for the Autumn: Specifically, around my passion for helping those with Hashimoto's and hypothyroidism, digestive complaints & SIBO uncover their "root causes" to dis-ease. And, finally a new look website, so I've got a lot of support coming your way, so please stay tuned!

In the very best of health,
