Our senior management team

Barry Smith

Founder & Chairman

Barry founded what was to become Symprove over 30 years ago after noticing a significant difference in the health of his cattle when fed grain treated with bacteria. After leading vets suggested the product could have benefits for humans, Barry led a research and development programme to produce a formula suitable for human consumption. The resulting food supplement became Symprove, which was launched as brand in 2010. Clinical research by leading academic bodies, including University College London and King’s College Hospital, London, has proven that Symprove arrives, survives and thrives in the gut, improving the balance of the gut microbiome. Barry is an expert in using food technology to manage wellbeing. He has previously run his own market garden business and was a medic in the British Army.
