Indication

Focus:
healthspan
Description:
To selectively feed beneficial gut bacteria, promoting a healthier microbiome composition and producing beneficial metabolites like short-chain fatty acids (SCFAs).

Typical Protocol

  • Typical doses range from 2.5 to 10 grams per day, often started low and titrated up to manage gastrointestinal side effects.

Expected Cost Mean

Low Cost:
15
High Cost:
40
Cost Type:
monthly
Description:
Cost for bulk powders or capsules; generally not covered by insurance.

Summary

Prebiotics are non-digestible fibers that act as food for beneficial gut bacteria, such as Bifidobacteria and Lactobacilli. This selective fermentation produces short-chain fatty acids (SCFAs) like butyrate, which serve as an energy source for colon cells, reduce inflammation, and improve gut barrier integrity. These effects contribute to systemic metabolic health and may mitigate age-related inflammation ('inflammaging').

Purpose

Nourishes beneficial gut bacteria to improve metabolic health.

Card Summary

Selectively feeds beneficial gut bacteria to produce anti-inflammatory compounds, supporting metabolic and immune health.

Impact

Score:
5.5
Justification:
Modulates a key aging system (microbiome) with systemic metabolic and inflammatory benefits.

Evidence

Grade:
A
Score:
8.5
Justification:
Extensive human RCTs confirm microbiome modulation; healthspan extension is inferred from biomarker data.

Safety

Score:
2.5
Justification:
Generally Recognized As Safe (GRAS); primary side effects are mild, dose-dependent gastrointestinal discomfort.

Flags

  • May cause significant gas, bloating, or abdominal discomfort, especially at higher doses or during initial use.
  • Individuals with SIBO (Small Intestinal Bacterial Overgrowth) or certain FODMAP sensitivities may experience worsened symptoms.
  • Rapidly increasing dosage can lead to diarrhea or cramping.

Verdict

A safe, evidence-based tool for optimizing gut health and metabolic function.
