Gut-Brain Axis
JADE+ GUT
Protocol 010 · Gut-Brain Axis
Your second brain, supported.
The gut microbiome signals the brain through the vagus nerve and short-chain fatty acids — shaping mood, immunity and metabolism. AETHERA GUT restores that axis, without the bloating most fibres cause.
The biology
The gut microbiome manufactures neurotransmitters and short-chain fatty acids that travel to the brain along the vagus nerve — the gut-brain axis. When the microbiome is depleted or the gut barrier is compromised, that signalling degrades, affecting mood, immunity and metabolic health. GUT rebuilds it from three angles: feed the good bacteria, reseed them, and repair the barrier.
What this protocol targets
Prebiotic fuel
Sunfiber PHGG — a tasteless, low-FODMAP fibre that feeds the microbiome without gas or bloating.
Live cultures
Multi-strain probiotics plus postbiotics, including strains studied on the gut-brain axis.
Barrier repair
L-glutamine, the primary fuel for the cells lining the gut, to support barrier integrity.
Calm signalling
L-theanine to support the relaxed, alpha-wave state along the gut-brain connection.
Who it's for
- Anyone with bloating, irregularity, or a sensitive digestive system
- People who notice the link between their gut and their mood or focus
- Those rebuilding gut resilience after antibiotics, stress or illness
