With over six years of experience, Clarissa Lenherr has established herself as one of the UK's leading nutritionists, and is the founder of her own private nutrition clinic on prestigious Harley Street in London. She has helped thousands of clients achieve optimal health through her passion for gut health, understanding that digestive health is fundamental to overall wellbeing.  Clarissa firmly believes that health begins in the gut, and she uses evidence-based strategies to address a wide range of gut health issues such as IBS, SIBO, chronic bloating and gut dysbiosis.

Clarissa’s personal experience with IBS and SIBO has played a significant role in shaping her expertise as a nutritionist. Her journey to find relief from her own gut health issues fuelled her passion for understanding the complexities of the digestive system - mental and physical. Clarissa's personal struggle lasted over 10 years, and after seeing nine different specialists (including doctors, gastroenterologists, psychiatrists, nutritionists, dietitians – across the globe!) with no relief, she took her health into her own hands and managed to find long-term, sustainable relief. This experience, like so many of her clients have gone through, has helped her gain a unique perspective and empathy towards her clients who may be struggling with similar issues.
