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.

Substances
3 substances in this food
Acetate
Most abundant SCFA supporting gut barrier integrity and immune regulation
Propionate
SCFA supporting neuroinflammation reduction, blood-brain barrier protection, and neurotransmitter regulation
Vitamin K2 (MK forms)
Calcium handling; potential roles in brain health; often co-occurs with fat-soluble vitamins
Preparation Notes
- Choose unpasteurized for live probiotics
- Regular but not excessive intake
- Part of fermented foods rotation
- Supports gut microbiome diversity
Biological Target Matrix
| Biological Target | Substance | Contribution Level | Therapeutic Areas | Mechanism of Action |
|---|---|---|---|---|
| Gut Microbiome | Acetate | Contextual / minor contributor | Byproduct of fibre fermentation; supports intestinal barrier integrity; regulates immune responses; promotes synthesis of key neurotransmitters such as dopamine and serotonin | |
| Gut Microbiome | Propionate | Contextual / minor contributor | Byproduct of fibre fermentation; supports intestinal barrier integrity; regulates immune responses | |
| Hormonal Response | Vitamin K2 (MK forms) | Contextual / minor contributor | Modulates calcium distribution; supports calcium handling and may support neural function; occurs in fermented foods and certain animal products | |
| Inflammation | Acetate | Contextual / minor contributor | Supports immune regulation and anti-inflammatory processes | |
| Inflammation | Propionate | Contextual / minor contributor | Helps reduce neuroinflammation and protects the blood-brain barrier; enhances cognitive function | |
| Insulin Response | Propionate | Contextual / minor contributor | Improves insulin sensitivity and glucose metabolism; helps stabilize blood glucose and reduce insulin resistance | |
| Neurochemical Balance | Propionate | Contextual / minor contributor | Stimulates secretion of norepinephrine and may influence dopamine regulation; promotes synthesis of key neurotransmitters |
