What Is LeanBiome?
Gut microbiome weight loss formula using L. Gasseri LG2055 โ the most-studied weight loss probiotic
The gut microbiome composition directly influences body weight through SCFA production, GLP-1 secretion, energy harvest from food, and systemic inflammation. LeanBiome targets the Firmicutes-to-Bacteroidetes ratio consistently associated with obesity in human microbiome studies.
