Gareth Zeal has been working as a nutritionist for over 20 years, has co-authored 5 Hundred health tips with Hazel Courtenay, lectures around the world on the benefits of nutrition in practice to naturopaths, health food retailers pharmacists and doctors.

When in the UK he has practices from Aberdeen to London but mostly concentrated around the north east. The majority of his clients have digestive issues but he still sees a number of athletes these days – not the premiership football club but more endurance marathon, tri-athletes and MMA fighters.
