Human Biology Was Shaped by the Natural World
For nearly all of human history, we lived in constant contact with the natural world - surrounded by environmental microbes that trained and regulated our immune system.
But in just the last fraction of our human timeline, industrialization, urban living, food processing, and hyper-sanitized environments removed that exposure.
What was once a balanced system is now left without critical inputs — contributing to a more reactive immune state and rising chronic disease.

Restoring the signals we lost
Kioga is restoring our Old Friends — beneficial, nature-derived microbes that humans co-evolved with for hundreds of thousands of years.
These microbes played a critical role in training the immune system to stay balanced, not overreactive, helping regulate inflammation across the body and brain.
By reintroducing these signals, we are building a new approach to health: one that targets stress, mood, and chronic disease at their biological origin.
Where Immune Balance Meets Brain Function
Introducing NeuroAlly™
Mycolicibacterium petrae KGA-10
NeuroAlly™ is the first ingredient built from the Old Friends category, developed to restore balance across the immune–brain axis at the root of how we experience stress. Developed from a proprietary Old Friends strain, NeuroAlly™ works by recalibrating immune activity, reducing neuroinflammatory tone, and supporting healthy communication between the immune system and the brain. This targets an upstream driver of stress offering a fundamentally different approach from traditional ingredients.
