Nikki gives individualised, science based, common sense advice. I would 100% recommend her. I was struggling with some menopausal changes (especially round my middle), I got to eat more! And it worked. She taught me all sorts of tips and tricks. Always positive and upbeat, an appointment I look forward to. Thanks Nik, you’re 5 star in my book
We love Nikki (my whole family goes to her) She knows her stuff and provides great and healthier alternatives to a well balanced lifestyle
Without Nikki Hart I would never been able to get to the finish line of 18 Ironman’s, including the World Champs in Kona and over 40 marathons, plus all the races in between. I have NEVER had a gastro problem and have always followed her pal the week before, the night before and during the race. She is the secret sauce to racing and being able to finish what you set out to achieve.
