Humbled by Possibility
Bloom Science is translating the therapeutic benefit of the ketogenic diet into innovative medicines for serious, life-interrupting illnesses.
our mission

Re-imagine better solutions for patients.


Make measurable improvements to outcomes.


Deliver these solutions to patients in a timeframe that matters.

hacking the ketogenic diet to identify therapeutic microbes

You’re more microbe than human – if you count all the cells in your body, only 43% are human.

Connecting the gut microbiota to diet, metabolism, neural activity and behavior, we are developing effective microbiota-based therapeutics to treat rare epilepsy syndromes and improve brain health.

The Ketogenic Diet
The ketogenic diet has been effectively used to treat refractory epilepsy and rare orphan epilepsy syndromes since the 1920's.
The Gut Microbiome
The gut is home to trillions of microorganisms that digest our food, educate our immune systems, control our metabolism and influence our brains. The ketogenic diet can alter the types and functions of microbes in the gut in ways that influence the nervous system.
The Gut-Brain Axis
Alterations in the microbial communities that inhabit us are implicated in a variety of neurological disorders, including epilepsy, autism, anxiety and Parkinson’s disease.

Microbial dietary metabolism regulates secondary metabolites that in turn influence neuronal function.
Seizure Protection
In preclinical studies, our data reveal a novel role specific bacteria play in providing seizure protection in epilepsy models and adds to our understanding of the important function our microbiome serves in modulating brain activity.

Our therapy is a community of specific strains of naturally-occurring microbes that modulate neuroactive molecules in our brain.

Bloom Science co-founder Dr. Elaine Hsiao provides overview of how the microbiome affects brain and behavior.


We seek to empower patients and families by bringing hope for conditions where there are few treatment options.

It is our responsibility to seek innovation, to understand the challenges faced by patients and their families, to communicate with them clearly and to openly develop medicines that transform their lives.
