The Procter & Gamble Company announced that it is collaborating with Cleveland Clinic and Cleveland HeartLab to develop and commercialize a diagnostic and management solution for a recently-discovered heart disease biomarker. As part of the partnership, Cleveland HeartLab will develop a diagnostic test to measure blood levels of TMAO, while Cleveland Clinic will work with Procter & Gamble to develop an over-the-counter product that could help people manage their TMAO levels.
