We are a microbiome science company pioneering innovations in probiotics and living medicines to impact human and planetary health. Founded to realize the potential of microbes, our platform enables the translation of breakthrough science across a portfolio that encompasses both indication-specific and preventive applications across gastrointestinal and digestive health, women’s health, skin and dermatological health, oral care, pediatrics, gut-brain function, metabolic function, and nutrition.

Founded in Venice, CA with a global team across Europe, Australia, Asia and North America, Seed Health was co-founded by Ara Katz and Raja Dhir, alongside a scientific board comprised of leading scientists, researchers, and clinicians across the fields of microbiology, immunology, bioinformatics, dermatology, oral health, vaginal health, gastroenterology, mental health, pediatrics, and nutrition.
