LeanBiome (Biome) Review: One Strain Hidden in a Blend

Is LeanBiome (Biome by Lean for Good) worth it?

Worth a look (5.6/10). LeanBiome (marketed on this funnel as 'Biome' by Lean for Good) does more label disclosure than most ClickBank supplements: the Supplement Facts panel gives a milligram and CFU figure for Lactobacillus gasseri, L. rhamnosus, inulin, green tea phytosome, Sphaeranthus indicus and Garcinia mangostana. The gasseri dose matches a real published trial, and the green tea phytosome dose matches its cited study exactly. The catch is Lactobacillus fermentum, one of the three 'key' strains the sales copy builds its case on, which turns out to be hidden inside a 10 mg, 5-billion-CFU proprietary blend shared with six other species, so its actual amount cannot be checked at all. The 180-day 'empty bottle' guarantee is genuinely strong.

What we liked

Real Supplement Facts panel with milligram and CFU numbers for most ingredients, unusual for this product category
Two ingredient doses (L. gasseri, green tea phytosome) match their own cited clinical trials
180-day 'empty bottle' refund, even if every capsule has been used
Named company, phone number and mailing address rather than an anonymous brand

What we didn't

The specifically-promoted L. fermentum strain is hidden inside an unlabeled 7-species blend
No 1-bottle option; minimum spend is $158 plus shipping
Inulin dose (200 mg) is far below typical prebiotic fiber research amounts
Sphaeranthus indicus and Garcinia mangostana evidence is rated low-quality by independent reviewers, more so than the page's own FAQ suggests
"Doctor Formulated" label seal with no doctor named anywhere

What is LeanBiome (Biome by Lean for Good)?

Biome is a delayed-release capsule sold as a gut-microbiome weight-loss aid, two capsules a day, 60 capsules (a 30-day supply) per bottle. The sales page argues that 'lean' and 'overweight' people differ in their gut bacteria, cites real twin studies on the gut microbiome, and proposes that adding specific 'lean bacteria' species and a green tea extract can rebalance that microbiome.

The Supplement Facts panel lists Lactobacillus gasseri (25 mg, 10 billion CFU), Lactobacillus rhamnosus (10 mg, 5 billion CFU), a 10 mg / 5-billion-CFU 'Proprietary Blend' of seven further species (L. fermentum, L. paracasei, L. plantarum, B. bifidum, B. lactis, B. longum, B. breve), inulin from chicory root (200 mg), Green Tea Phytosome / Greenselect Phytosome (300 mg), Sphaeranthus indicus (300 mg) and Garcinia mangostana pericarp (100 mg), plus standard capsule fillers.

The product is made by Lean for Good, based in Wilmington, Delaware, with a distribution address in Talmadge, Ohio. It is sold and billed through ClickBank, which handles the order and refund process; the sales page also lists a phone number and mailing address, which is more identifying information than many listings in this category provide.

Format: Delayed-release capsule, 60 per bottle, 2 a day. Sold by: Lean for Good (sold through ClickBank).

What is on the LeanBiome (Biome by Lean for Good) label?

Each row compares what the label or sales page states with what published research used. When an amount is missing, there is nothing to compare, and we say so.

IngredientPer servingWhat research used

Lactobacillus gasseriIn studied range25 mg (10 billion CFU)Kadooka et al. 2013 (Br J Nutr) found reduced visceral fat with as little as about 10^8 CFU/day of L. gasseri SBT2055The labeled 10 billion CFU meets or exceeds the dose range shown to reduce abdominal fat in the cited randomized trial, and the trial's 8.5% figure that the sales page quotes matches the published result for the higher of its two active-dose groups.

Lactobacillus rhamnosusBelow studied dose10 mg (5 billion CFU)The Universite Laval trial on L. rhamnosus for weight loss in women used roughly twice this daily CFU countA real strain with real research behind it, but the label amount is lower than the dose used in the trial the sales page describes.

Proprietary blend: L. fermentum, L. paracasei, L. plantarum, B. bifidum, B. lactis, B. longum, B. breveCan't verify10 mg combined (5 billion CFU combined)Omar et al. 2013 tested L. fermentum on its own, not as one-seventh of a 10 mg blendL. fermentum is one of the three strains the sales page's body copy specifically credits with a clinical trial, yet on the actual label it is only one of seven species sharing a single 10 mg, 5-billion-CFU line. There is no way to know how much L. fermentum, if any meaningful amount, is actually in a serving.

Inulin (from chicory root)Below studied dose200 mgPrebiotic fiber trials typically use multi-gram daily doses200 mg is a small fraction of the several grams of inulin used in most prebiotic fiber research; at this amount it functions more as a minor filler than a dosed fiber supplement.

Green Tea Phytosome (Greenselect Phytosome)In studied range300 mgDi Pierro et al. 2009 (Altern Med Rev) used 300 mg/day of Greenselect Phytosome alongside a calorie-controlled dietThis is the one ingredient where the label dose exactly matches the cited clinical trial's dose, though that trial paired the extract with an active calorie-controlled diet, not the extract alone.

Sphaeranthus indicusBelow studied dose300 mgA 2020 systematic review (Maunder et al., Diabetes Obes Metab) found this combination showed statistically and clinically significant weight loss in a small number of trials, but flagged poor methodological qualityIndependent review literature is more cautious about this combination than the sales page's FAQ, describing the evidence as limited and of generally poor quality despite a positive signal.

Garcinia mangostana (pericarp)Below studied dose100 mgUsually studied together with Sphaeranthus indicus rather than aloneSame caveat as Sphaeranthus indicus above: promising in a handful of small trials, but independent reviewers rate the evidence quality as weak.

Unlike most products in this category, Biome does publish a real Supplement Facts panel with milligram and CFU numbers for every ingredient. The exception that matters is the seven-species 'Proprietary Blend,' which hides the amount of Lactobacillus fermentum, a strain the sales copy specifically promotes using a study of that species alone.

Do the LeanBiome (Biome by Lean for Good) claims hold up?

"Lactobacillus Gasseri... 8.5% of belly fat" in 12 weeks

This closely matches the actual result reported in Kadooka et al. 2013 (Br J Nutr) for the higher of two active-dose fermented-milk groups; the label's 10 billion CFU is consistent with an effective dose from that line of research.

"Nine clinically-researched lean bacteria species" combined with Greenselect Phytosome in the 'clinically-studied dosages'

Only two of the nine listed bacterial species (L. gasseri, L. rhamnosus) have a stated individual dose; the other seven, including L. fermentum which the page discusses by name with its own cited study, are combined into one unlabeled 10 mg blend.

"Greenselect Phytosome... 30 lbs" of weight loss in a cited 90-day trial

Di Pierro et al. 2009 did report roughly this scale of extra weight loss with 300 mg/day of Greenselect Phytosome on top of a calorie-controlled diet; Biome's label dose of 300 mg matches the trial, though the trial's diet component is a factor the sales page does not emphasize.

"Clinically-shown in multiple studies to reduce belly fat" (Sphaeranthus indicus and Garcinia mangostana)

A 2020 independent systematic review found a positive but low-quality evidence base for this specific combination, a more cautious framing than the sales page's FAQ answer suggests.

How much does LeanBiome (Biome by Lean for Good) really cost?

Option	Total	Per month	Shipping
2 bottles	$158	$79	$9.95 US / $19.95 international
3 bottles	$207	$69	$9.95 US / $19.95 international
6 bottles	$294	$49	Free in the US

There is no single-bottle option. The cheapest way to try Biome is the 2-bottle package at $79 a bottle ($158 total) plus $9.95 US shipping ($19.95 outside the US), covering a 60-day supply. The 3-bottle package is $69 a bottle ($207 total) with the same shipping fees, and the 6-bottle package drops to $49 a bottle ($294 total) with free US shipping.

On a monthly basis that is roughly $79, $69 or $49, depending on the bundle, which sits in the middle of the price range for ClickBank weight-loss supplements.

We reached the actual ClickBank order form for the 2-bottle bundle; it offered an optional paid 'Shipping Insurance' add-on before checkout, which is not required and can be declined without affecting the order.

There is no single-bottle option; the smallest package is 2 bottles. The 2 and 3 bottle bundles add $9.95 shipping in the US or $19.95 outside it. The 6-bottle bundle ships free in the US (international shipping cost for that bundle is not shown on the page). The order page we reached separately offered an optional paid 'Shipping Insurance' add-on, which is not required to complete checkout.

Can you get a refund on LeanBiome (Biome by Lean for Good)?

180-day window. The sales page promises a 180-day 'empty bottle' money-back guarantee, explicitly stating a refund applies even if every capsule has been used, and the ClickBank order form confirms a return or replacement window of 180 days from purchase.

Step by step: find the ClickBank receipt email, look up the order at clkbank.com and ask for a refund in writing. Our ClickBank refund guide covers returns, extra offers and auto-ship.

Which red flags did we find?

Key strain hidden in a blendLactobacillus fermentum is promoted by name with its own cited study, but on the label it is one of seven species sharing a single 10 mg, 5-billion-CFU 'Proprietary Blend' line, so its actual dose is unknown.
Inulin dose far below typical fiber research200 mg of inulin is a small fraction of the multi-gram doses used in most prebiotic fiber studies.
No 1-bottle trial optionThe smallest package is 2 bottles for $158 plus shipping; there is no way to try a single bottle before committing to a 60-day supply.
Reference list uses '0besity' spelling throughoutThe sales page's own scientific-reference list repeatedly spells 'obesity' as '0besity' (with a zero), a pattern consistent with deliberately dodging ad-platform content filters rather than a typo.
"Doctor formulated" seal without a named doctorThe product label carries a circular 'Doctor Formulated' stamp, but no doctor's name, credentials or license appears anywhere on the sales page or label.

Who should buy LeanBiome (Biome by Lean for Good), and who should skip it?

It may suit you if

You want a probiotic and green tea combination where most ingredients carry a real, checkable milligram and CFU number, and you are comfortable that one blend of seven species is not individually dosed.
You are prepared to commit to at least a 2-bottle, 60-day purchase since there is no smaller trial size, and you plan to use the 180-day guarantee if it does not work for you.

Skip it if

You specifically want to test Lactobacillus fermentum at a known dose; here it disappears into an undisclosed blend.
You want to try a single bottle first. The minimum order here is two bottles.
You are looking for a meaningful daily fiber dose from the inulin; at 200 mg it is far below typical prebiotic amounts.

LeanBiome (Biome by Lean for Good) FAQ

Is LeanBiome / Biome a scam?

No. It is a real product with a genuine Supplement Facts label and a documented 180-day refund through ClickBank. The main criticism is that one of its headline strains, L. fermentum, is hidden inside an undisclosed blend rather than dosed on its own.

How much does Biome cost?

There is no single-bottle option. Two bottles (a 60-day supply) cost $158 plus shipping, three bottles cost $207, and six bottles cost $294 with free US shipping, working out to $79, $69 or $49 a month.

What are the side effects of Biome?

The label lists no specific side effects but advises pregnant or nursing women, people under 18, and anyone with a medical condition to consult a physician first. Probiotics can cause mild digestive changes in some people when starting.

How do I get a Biome refund?

Contact Lean for Good's customer support (phone or email, provided with the order) within 180 days of purchase; the company states it will refund the full purchase price even if every bottle has been used.

Does the probiotic strain in Biome match the studies it cites?

Partly. Lactobacillus gasseri is dosed at a level consistent with its cited trial. Lactobacillus fermentum, also cited by name, is combined with six other species in one small proprietary-blend line, so its actual dose cannot be confirmed.
