LeanBiome Review 2026: Can This ‘Lean Bacteria’ Formula Finally Fix Unexplained Weight Gain?
You follow the diets. You do the exercise. You cut calories until you’re exhausted and hungry, yet the stubborn fat—especially around your belly—refuses to budge. It’s a frustrating, demoralizing battle that makes you feel like you’re doing something wrong.
But what if it’s not your fault? What if the root cause of your weight gain has nothing to do with willpower and everything to do with a newly-discovered imbalance deep inside your gut?
This is the Ivy League-backed breakthrough behind Biome® (also known as LeanBiome), the world’s first formula designed to reverse this imbalance, repopulate your gut with ‘lean bacteria,’ and help you finally achieve the slim, energetic body you deserve.
1. What is Biome®?
Biome® (LeanBiome) is a doctor-formulated, next-generation dietary supplement designed to support healthy weight loss by rebalancing the gut microbiome. Its unique and proprietary formula is delivered in a simple, delayed-release capsule.
It is the only product in the world that combines nine clinically-researched ‘lean bacteria’ species with Greenselect Phytosome®, a caffeine-free, high-absorption green tea extract. Together, these ingredients work to address the newly-discovered root cause of belly fat and unexplained weight gain.
2. How Does It Work?
Recent groundbreaking research from top universities has shown that the gut is home to trillions of bacteria. An imbalanced gut, or a “gut swamp,” is filled with “fat bacteria” that increase hunger, amplify cravings, and ramp up fat storage. In contrast, a “lean microbiome” is dominated by “lean bacteria” that suppress hunger, quell cravings, and fire up the metabolism.
LeanBiome works through a powerful two-step process to transform your gut from a swamp into a lean microbiome:
It Repopulates Your Gut with ‘Lean Bacteria’: The formula introduces nine clinically-proven species of lean bacteria (like Lactobacillus Gasseri) into your gut. The delayed-release capsule protects the bacteria from stomach acid, ensuring they arrive alive and ready to “crowd out” the fat bacteria, effectively turning off the signals that cause cravings and fat storage.
It Fires Up Your Metabolism: LeanBiome includes Greenselect Phytosome®, a caffeine-free green tea extract formulated with patented Phytosome technology. This technology boosts absorption by 2-3 times, allowing the extract to get to work quickly, increasing your metabolism and helping your body burn through existing fat stores without causing jitters or sleepless nights.
