LeanBiome is a gut-health-based weight loss supplement created by Lean for Good, a U.S.-based health and wellness company. It’s manufactured in an FDA-registered, GMP-certified facility, ensuring each capsule meets strict quality and safety standards.

How Does LeanBiome Work?

Your gut is home to trillions of bacteria and some are “good” and support health, while others are “bad” and can cause weight gain, bloating, and low energy. When this delicate balance is disrupted, your body may:

  • Store more fat (especially around the belly)
  • Experience constant cravings for sugary, high-calorie foods
  • Burn fewer calories, even at rest

LeanBiome is designed to restore your gut’s healthy bacteria using a blend of probiotics and prebiotics. This balance can lead to better digestion, a faster metabolism, and fewer cravings.

Scientific Evidence Behind LeanBiome

LeanBiome’s formula isn’t just based on marketing claims — several of its key ingredients have been studied for their impact on weight management, gut health, and metabolism. Below is a summary of the most relevant scientific findings.


Lactobacillus gasseri

  • Study Evidence: A 12-week randomized, double-blind study in adults showed that L. gasseri supplementation led to an 8.5% reduction in abdominal fat compared to placebo (PubMed).
  • Why It Matters: Abdominal fat is closely linked to metabolic issues, and reducing it can improve overall health.
  • LeanBiome Role: Helps shrink belly fat and support a healthier body composition.

Lactobacillus rhamnosus

  • Study Evidence: In a 24-week clinical trial, overweight women taking L. rhamnosus lost ~9.7 lbs — almost double the placebo group (PubMed).
  • Why It Matters: This strain appears to influence appetite-regulating hormones and fat metabolism.
  • LeanBiome Role: Helps control cravings and promotes steady fat loss.

Leanbiome: Lactobacillus fermentum

  • Study Evidence: Participants in a 43-day trial experienced a 3% body fat reduction after supplementing with L. fermentum (PubMed).
  • Why It Matters: Suggests this probiotic can contribute to fat reduction alongside diet and exercise.
  • LeanBiome Role: Supports lean body composition and gut health.

Green Tea Phytosome (Greenselect®)

  • Study Evidence: Overweight participants who took this caffeine-free extract lost up to 30 lbs in 90 days compared to diet alone (PubMed).
  • Why It Matters: Boosts metabolism and fat oxidation without stimulant side effects.
  • LeanBiome Role: Enhances calorie burning and supports long-term weight loss.

Inulin (from Chicory Root)

  • Study Evidence: A systematic review found that inulin-type prebiotics improve gut microbiota diversity and may aid weight loss by promoting satiety (Harvard School of Public Health).
  • Why It Matters: Feeding good bacteria creates a healthier gut environment, which can indirectly help weight control.
  • LeanBiome Role: Acts as “food” for probiotics, boosting their effectiveness.

💡 Quick Takeaway:
While LeanBiome as a complete formula hasn’t been the subject of large-scale clinical trials, many of its individual ingredients are supported by credible, peer-reviewed studies showing potential benefits for weight management and gut health.
