What is Biome?
Biome is a vegetarian, probiotic-focused weight‑management supplement from Lean for Good designed to rebalance the gut microbiome linked to cravings, fat storage, and sluggish metabolism.
The formula combines a “Lean Bacteria Blend” with Greenselect Phytosome, a caffeine‑free green tea extract, and is sold with a 180‑day “empty bottle” money‑back guarantee.
Why gut-first weight loss
Emerging research suggests that shifting the gut ecosystem toward beneficial species can influence appetite regulation, metabolic rate, and where fat is stored.
Biome is positioned to “drain the swamp” of a dysbiotic gut by introducing specific strains studied for waistline and visceral fat outcomes, which the brand frames as the root cause of stubborn weight.
Key ingredients at a glance
- Lactobacillus gasseri: Human trials associate specific L. gasseri strains with reductions in visceral fat and waist circumference over 12 weeks.
- Lactobacillus rhamnosus: A 24‑week study found women using LPR saw greater weight and fat loss than placebo, especially during maintenance.
- Lactobacillus fermentum: Evidence points to fat‑loss and lipid improvements, with human and animal data exploring mechanisms like increased energy expenditure.
- Greenselect Phytosome: A decaffeinated, highly bioavailable green tea extract with clinical data for weight management and maintenance when paired with diet.
- Prebiotic support: Inulin‑type fibers can nourish the probiotics and help them establish a more favorable microbiome.

What the science says
In obese adults, L. gasseri BNR17 lowered visceral adipose tissue compared with placebo over 12 weeks, aligning with abdominal fat and waist benefits seen in other randomized trials.
L. rhamnosus demonstrated a sex‑specific effect, with women showing significantly greater weight and fat loss over 12–24 weeks under structured diet phases.
Greenselect Phytosome has human data indicating enhanced weight loss and better maintenance versus diet alone, likely via catechin bioavailability without caffeine.
Expected benefits and timeline
Brand guidance emphasizes cumulative results over 3–6 months, reflecting clinical durations used for L. gasseri, L. rhamnosus, and Greenselect.
Commonly reported outcomes include steadier appetite, fewer cravings, and changes in waistline as the gut ecosystem shifts and the formula is taken consistently.
How to take it
Take two capsules daily with water, preferably in the morning before breakfast, with each bottle supplying 30 days.
Bundles of 3–6 months are recommended to avoid breaks and align with study timelines cited by the brand.

Pros and cons
- Multi‑strain probiotic blend plus Greenselect targets gut, cravings, and metabolism from complementary angles.
- Long, no‑risk trial window supports real‑world testing across multiple gut cycles.
- Clinical backing exists for individual components, including reductions in visceral fat and improved weight maintenance.
- Best results often require 12+ weeks of consistency and lifestyle alignment.
- Human evidence for some L. fermentum strains is less robust than for L. gasseri or L. rhamnosus.
- Only available online from Lean for Good, which limits retail convenience.
Who Biome is for
Biome suits adults who prefer stimulant‑free, gut‑centric approaches and can commit to daily use over a 3–6 month horizon.
Those already focused on whole‑food fiber and a calorie‑smart plan may see additive benefits, given the synergy with prebiotics and catechin delivery.
Biome vs typical fat burners
How to maximize results
- Take two capsules daily before breakfast and avoid missed days to support colonization and consistency.
- Pair with a calorie‑controlled, whole‑food plan to mirror clinical contexts for catechin‑based support.
- Increase dietary prebiotic fiber to feed beneficial strains and reinforce microbial diversity.
What results to expect
Across 12+ weeks, users commonly target changes in waist and visceral fat alongside steadier appetite, rather than dramatic week‑one scale shifts.
Greenselect’s maintenance data suggest benefits are more durable when habits remain consistent after active loss.
