Industry Experts on Microbiome Therapeutics Market

Driven by the escalating prevalence of chronic diseases linked to microbiome dysbiosis, such as metabolic disorders and certain autoimmune conditions, the microbiome therapeutics industry is expected to grow in the near future.

Dr. Gabriel Leventhal (Chief Scientific Officer, PharmaBiome), stated that, “The microbiome represents a new frontier for modern medicine. Traditional therapies typically focus on “fixing” problems by modifying the human body, for example clearing clogged arteries, removing pathogens, or even editing defects to our genetic code. The microbiome is fundamentally different in that it functions as an essential ‘support system’ – both integral to the functioning and health of our bodies, and external to us. While we don’t have full control over which bacteria live inside our guts, we can control the environment that microbes experience there, which might favor some strains more and others less.”
