Four connected research paths

Foundation

Probiotics

What probiotics are, how strains differ, and how to read labels.

Evidence

Microbiome & Weight

What researchers know—and do not know—about gut microbes and body weight.

Entities

Probiotic Strains

Why exact strain identity matters when interpreting clinical research.

Commercial

LeanBiome

An independent review, ingredient analysis, pricing and alternatives.

Buyer education

Choosing a Probiotic

Compare strains, CFUs, labels, evidence and quality signals.

Comparison

Probiotics vs Prebiotics

Understand two commonly confused microbiome concepts.

Health-content standard

Probiotic evidence is outcome- and strain-specific. NIH says body-weight findings are inconsistent and additional research is needed. We do not turn a positive ingredient study into a guarantee for a commercial formula.
