Dr Rianne Costello
Performance Nutritionist and Equestrian
Rianne is a Registered Performance Nutritionist and the founder of Invictus Performance Nutrition, working primarily with elite figure skaters and other athletes to help them fuel training, optimise recovery and perform at their best. She uses Get Buzzing bars with her athletes as a convenient, tasty and Informed Sport tested option for fuelling around busy training and competition schedules. Away from nutrition she competes her horse Elvis in eventing and show jumping, so she knows first-hand the importance of keeping energy levels topped up when training and competing.

Tiff Williams
Senior Performance Nutritionist and Recipe Developer
Tiff has worked with Get Buzzing since 2018. She is a Senior Performance Nutritionist and a Practitioner member of the UK’s Sport & Exercise Nutrition Register, and much of her recent work has been with professional athletes across football and Formula 1, alongside promising youth athletes from a range of backgrounds. She is also our recipe developer, known as The Cooking Yam, creating inventive recipes using every flavour of Get Buzzing bar. When she isn’t helping athletes optimise their nutrition, you’ll usually find her in the pool or in the kitchen making something creative.
We’re always looking for energetic, passionate people who love Get Buzzing. Whether you’re a cyclist, fitness enthusiast, marathon runner or simply a fan of natural snacks, we’d love to hear from you.
