The gut-brain axis in plain English

Why what you feed your microbiome at 7am shapes your concentration at 3pm — and the four levers that actually matter.

The vagus nerve is a two-way street. Roughly ninety percent of its traffic runs from gut to brain, carrying short-chain fatty acids, neurotransmitter precursors and inflammatory signals from a microbiome that outnumbers your own cells.

Four levers

  • Fibre diversity — at least thirty plant species a week.
  • Polyphenols — pigments that selectively feed Akkermansia and Bifidobacterium.
  • Live cultures — robust, acid-tolerant strains delivered daily.
  • Time — twelve to fourteen hours overnight without food.
  • Three of the four come in the pouch

    H-1 carries 11 organic greens, the Chromatic polyphenol matrix, and 5 billion CFU of shelf-stable Lactobacillus and Bifidobacterium per serving. The fourth lever is yours.
