Sauerkraut

Overview

Sauerkraut is fermented cabbage providing live Lactobacillus probiotics, postbiotic compounds, and enhanced nutrient bioavailability. Fermented foods such as sauerkraut, kimchi, kefir, miso, and kombucha provide live microbes + postbiotic peptides; improved SCFA pools; vagal signaling.

Biological Target Matrix

Biological Target	Substance	Contribution Level	Therapeutic Areas	Mechanism of Action
Gut–Brain Axis & Enteric Nervous System (ENS)	Acetate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Byproduct of fibre fermentation; supports intestinal barrier integrity; regulates immune responses; promotes synthesis of key neurotransmitters such as dopamine and serotonin
Gut–Brain Axis & Enteric Nervous System (ENS)	Propionate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Byproduct of fibre fermentation; supports intestinal barrier integrity; regulates immune responses
Inflammation & Oxidative Stress	Acetate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Supports immune regulation and anti-inflammatory processes
Inflammation & Oxidative Stress	Propionate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Helps reduce neuroinflammation and protects the blood-brain barrier; enhances cognitive function
Neurotransmitter Regulation	Propionate	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Stimulates secretion of norepinephrine and may influence dopamine regulation; promotes synthesis of key neurotransmitters
