The LeanBiome Story

Why LeanBiome Exists

LeanBiome was created by Lean for Good® around a simple, research-backed idea: the balance of bacteria in your gut plays a powerful role in how your body manages weight, appetite and metabolism. We believe that supporting a healthier gut microbiome is one of the most sustainable ways to support healthy fat loss — without harsh stimulants or crash diets.

Our formulation team brought together nine clinically researched probiotic strains, a caffeine-free green tea extract called Greenselect Phytosome®, and prebiotic inulin into one daily supplement. The goal was to give adults a practical, daily tool to help rebalance their gut bacteria, calm cravings, and support a more efficient metabolism.

Our Scientific Foundation

LeanBiome's approach is grounded in the science of the gut microbiome — the trillions of bacteria living in the digestive tract. Emerging research suggests that people with a diverse, "lean" microbiome profile may process calories and store fat differently than those with an imbalanced gut. LeanBiome is designed to support that lean-bacteria balance with three core components:

  • Lean Bacteria Blend — Nine probiotic strains including Lactobacillus gasseri, L. rhamnosus and L. fermentum, selected because published human studies associate them with reduced abdominal fat, better appetite regulation and improved body composition.
  • Greenselect Phytosome® — A patented, caffeine-free green tea extract formulated for enhanced absorption. Clinical trials suggest it may support fat oxidation and weight maintenance when combined with a low-calorie diet.
  • Prebiotic Inulin — A plant-based fiber that feeds beneficial bacteria and helps them colonize the gut more effectively.

Clinical Evidence Behind Our Ingredients

Each ingredient in LeanBiome is chosen based on published, peer-reviewed clinical evidence on individual ingredients. Notable studies that shaped our thinking include:

  • Kadooka et al. (2013) — A randomized controlled trial in the British Journal of Nutrition found that Lactobacillus gasseri SBT2055 reduced abdominal adiposity in adults.
  • Sánchez et al. (2014) — Research published in the British Journal of Nutrition linked Lactobacillus rhamnosus CGMCC1.3724 supplementation to improved weight loss and maintenance in obese men and women.
  • Omar et al. (2013) — A study in the Journal of Functional Foods reported that Lactobacillus fermentum and L. amylovorus altered body adiposity and gut microflora in healthy adults.
  • Di Pierro et al. (2009) — A clinical trial published in Alternative Medicine Review showed Greenselect Phytosome® supported weight loss as an adjunct to a low-calorie diet.
  • Gilardini et al. (2016) — A randomized placebo-controlled study in BMC Complementary Medicine and Therapies found Greenselect Phytosome® helped with weight maintenance after weight loss in obese women.
