Our take
Seed Health is a microbial company that researches, develops and sells probiotic supplements to boost gastrointestinal, dermatological oral, pediatric and nutritional health.
The last decade has seen a renewed focus on probiotics, and gut health in particular, with scores of companies bringing supplements to market. However the efficacy of many of these are still shrouded in doubt, and lacking in insightful scientific research. Seed appears committed to upping (and setting) the standard. The company’s chief scientist, Dr. Gregor Reid, is a global authority in microbial sciences, having chaired the UN-WHO panel that first defined the term “probiotics”. On top of this, the company’s advisory board comes with a strong resume in microbiology, immunology, genetics, metabolomics, gastroenterology, pediatrics, environmental sciences and women’s health.
The next big step for Seed Health will be to rise above an already crowded marketplace while continuing R&D for new product categories, with a particular focus on AI applications. Substantial funding in 2021 alongside stable profitability and the fostering of groundbreaking partnerships with the likes of the Swiss Institute of Allergy prove it is turning heads in the science sector.
