Defining the category, in the open.
Opinion and thought leadership from our scientists — on the gut-brain axis, precision modulation of the microbiome, the biology of keystone gut species, and what "evidence" should mean for functional ingredients.
The brain is not sealed
The immune cells defending your brain were supposed to last a lifetime. New human data shows they start being replaced around fifty, and the replacements are educated somewhere unexpected.
A remote control for memory, hidden in the gut
A new Nature paper shows an aging gut can drive memory loss on its own — and reverse it. The twist is which molecule does the damage.
A GLP-1 drug treated depression without touching its receptor
A GLP-1 drug relieved depression in mice with its receptor deleted. The effect ran through a single gut bacterium, not the brain. What the science says about the gut microbiome and mental health, and where it doesn't.
Beyond biotics: the case for precision bioactives
Probiotics add live bacteria; fibre feeds them in bulk. Our co-founder Tim Mak told Fi Global about a third path — plant-derived bioactives that reprogramme the gut bacteria a person already carries.
The window for fixing the gut-brain axis closes earlier than we thought
Diversity is key to a healthy gut
Nutrition & Longevity: Walking through Hong Kong's markets—greens, reds, purples, and yellows—highlights a vital truth: diversity in diet is essential for a healthy gut and overall well-being.
