What Is Lean Biome?
LeanBiome® is a cutting-edge dietary supplement developed by Lean for Good®. It blends nine probiotic strains with the patented Green Tea Phytosome® to address the newly discovered link between gut microbiome health and weight gain. By restoring “lean bacteria” and suppressing “fat bacteria,” it aims to reduce cravings, boost metabolism, and support long-term fat loss naturally.
About Lean for Good®
Lean for Good® positions itself as a science-first wellness company. Unlike brands that rely on hidden subscriptions or gimmicks, it emphasizes direct-to-customer transparency, premium ingredients, and customer satisfaction. Every bottle is produced in FDA-approved, GMP-compliant facilities in the United States. Purchases are protected by a 180-day empty-bottle refund policy, offering risk-free access to this supplement.
How Does LeanBiome Work?
The product is based on the groundbreaking twin study from King’s College London, which demonstrated that lean individuals had gut microbiomes rich in “lean bacteria,” while overweight individuals had microbiomes dominated by “fat bacteria.”
Lean Bacteria Support:
- Appetite suppression
- Reduced cravings
- Faster metabolism
- Lower fat storage
Fat Bacteria Promote:
- Strong hunger signals
- Increased cravings
- Sluggish calorie burning
- More fat accumulation
LeanBiome® reverses this imbalance by seeding the gut with lean bacteria strains and enhancing their growth with inulin fiber. Combined with Green Tea Phytosome®, this synergy helps optimize digestion, regulate appetite, and improve fat metabolism.
Ingredients in LeanBiome®
LeanBiome® stands out for its clinically studied combination of probiotics, prebiotics, and plant extracts designed to reset the gut microbiome and accelerate fat loss.
Green Tea Phytosome® (GreenSelect®) – A patented green tea extract that’s 3x more bioavailable than standard green tea. Rich in polyphenols, it helps stimulate thermogenesis, promote fat oxidation, and reduce waist size. Importantly, it’s caffeine-free, eliminating the jitters associated with traditional green tea.
Lactobacillus Gasseri – This strain is linked to reduced abdominal fat and waist circumference. Studies show it lowers fat absorption, enhances satiety, and regulates leptin, the hormone that controls appetite.
Lactobacillus Rhamnosus – Extensively studied in weight management, especially for women, where it demonstrated significant reductions in body weight and fat mass. It also helps balance gut flora during dieting, preventing rebound weight gain.
Lactobacillus Fermentum – Offers strong antioxidant protection, helps lower systemic inflammation, and improves cholesterol levels. Its effect on oxidative stress contributes to improved metabolic health and reduced fat buildup.
Lactobacillus Plantarum – One of the most versatile probiotics, known for supporting digestive health and reducing intestinal inflammation. It improves nutrient absorption and helps regulate cravings through gut-brain signaling.
Lactobacillus Paracasei – A metabolism-supporting strain that improves energy efficiency, assists in fat breakdown, and has been associated with improved insulin sensitivity, an important factor in weight control.
Bifidobacterium Breve – A probiotic studied for its role in fat metabolism. It helps the body break down fat more efficiently and may also improve skin clarity by reducing inflammation.
Bifidobacterium Bifidum – Supports immunity, prevents harmful bacteria growth, and improves nutrient absorption. Its role in strengthening gut barrier integrity makes it vital for overall metabolic balance.
Bifidobacterium Lactis – Known for reducing bloating and improving bowel regularity, it enhances digestion while promoting a flatter stomach and greater comfort.
Bifidobacterium Longum – Plays a dual role in both gut and mental health. It reduces stress-related eating by lowering cortisol levels while also supporting digestion and immune regulation.
Inulin (from Chicory Root) – A natural prebiotic fiber that nourishes the probiotics in LeanBiome®. Inulin helps regulate bowel movements, improves satiety, and lowers calorie intake by enhancing feelings of fullness.
Sphaeranthus Indicus – A traditional Ayurvedic herb recognized for its metabolic-enhancing and anti-inflammatory effects. It has been shown in modern research to help with lipid metabolism and fat oxidation.
Garcinia Mangostana (Mangosteen) – A fruit extract rich in antioxidants, especially xanthones, which reduce inflammation, support blood sugar stability, and may directly influence fat-regulating pathways.
How Do I Take LeanBiome?
The recommended dose is 2 capsules daily, taken with water, preferably in the morning. Regular daily use is critical for results.
Caution: Do not exceed recommended dosage. As with any dietary supplement, you should consult your healthcare provider before use, especially if pregnant, nursing, have a medical condition, are taking medications, or have known adverse reactions or allergies.

Benefits Of LeanBiome
1. Sustainable Weight Loss
Targets root causes of weight gain instead of masking symptoms. LeanBiome® gradually reduces fat storage by shifting microbiome balance. Results are steady and sustainable, avoiding rebound weight gain.
2. Reduced Cravings & Appetite
By regulating ghrelin and leptin, LeanBiome® curbs hunger signals and reduces dependence on sugar and processed foods. This natural appetite control makes dieting easier and more effective.
3. Boosted Metabolism & Energy
Activates thermogenesis through probiotics and Green Tea Phytosome®, turning the body into a fat-burning machine. Provides gentle energy enhancement without caffeine crashes.
4. Improved Digestive Health
The probiotics and inulin fiber restore digestive balance, reduce bloating, and support smoother digestion. Many users experience increased comfort and regularity within weeks.

6. Long-Term Body Composition Support
By reducing fat while supporting muscle preservation, LeanBiome® helps reshape body composition naturally, supporting long-term wellness and confidence.
