The biology behind the game
Tanya's health bar is her gut microbiome. Like a real tapir — and like you — she is a hindgut fermenter: the bacteria in her colon ferment plant fibre into short-chain fatty acids, which keep the gut lining fed and the whole system in balance. Fibre-rich food feeds them; sugary, deep-fried and ultra-processed food mostly doesn't.
The capsules are real: TRI-01 induces keystone gut species already present in the gut, and TRI-04 is a precision prebiotic fibre for the butyrate producers. In the game they give Tanya a shield. In real life they are ingredients for brands, and the science is on the ingredients page.
It's a game, not nutrition advice.
