Quick Verdict
| Product | Everlean, from Peak Biome |
| Category | Probiotic capsule marketed specifically for weight management, built around a gut-bacteria and fat-absorption story |
| Our Rating | 5.5/10. Real, named probiotic strains with genuine (if narrow and often single-study) research behind several of them, undercut by cherry-picked percentage statistics and an oversimplified ‘poop out the fat’ pitch |
| Price | $49.95 for 1 bottle; $39.95 per bottle on the 3-bottle package ($119.85); $33.33 per bottle on the 4-plus-2-free package ($199.98 for 6 bottles), per the vendor’s site at the time of writing |
| Money-Back Guarantee | Stated as a 6-month, 100 percent money-back guarantee on the main sales page (a related order-bump page on the same site states 3 months; confirm the exact window at checkout) |
| Best For | People already interested in a probiotic for general digestive comfort who want to treat any weight-related benefit as a modest bonus, not the main event |
| Not Ideal For | Anyone expecting a 427 percent or 120 percent improvement in their own fat loss, since those numbers come from specific isolated studies on single strains, not from a trial on this six-strain blend |

What Is This Product?
This is a probiotic weight-management capsule from Peak Biome, sold through ClickBank. Rather than the usual thermogenic or appetite-suppressant story most ClickBank diet pills use, this one is built entirely around gut bacteria: the pitch is that certain probiotic strains can increase a protein called ANGPTL4 (angiopoietin-like 4), which the sales page describes as letting your body ‘poop out’ dietary fat instead of absorbing it, while also reducing cravings and shrinking existing fat cells.
The sales page is a long-form, story-driven letter (following the same ‘here’s how I discovered this’ format common across the ClickBank weight-loss category), citing a long list of real, named scientific studies and university names (Harvard, Mayo Clinic, Laval Medical University, and others) as background for the gut-bacteria and weight-loss connection.
The ‘Poop Out the Fat’ Claim and the 427% / 120% Statistics
ANGPTL4 is a real protein studied in metabolic research, and it is true that it plays a role in regulating how the body handles circulating fat. The sales page’s plain-language summary, that certain gut bacteria can nudge this system so some dietary fat passes through undigested, is a real, if heavily simplified, description of one proposed mechanism in the scientific literature.
Where the marketing goes further than the evidence supports is in how the percentage statistics are presented:
- The claim that people ‘lost 427% more weight’ using this approach traces to a single cited study description on the sales page itself, not to a trial of this six-strain product. A relative percentage like this, without the underlying absolute numbers and study design in front of you, is very easy to make sound far more dramatic than it is.
- The claim of ‘120% more fat’ lost similarly traces to one specific trial of a single strain (Lactobacillus rhamnosus) against a placebo, not to a trial of the finished multi-strain formula.
- The page also cites a ‘Zhejiang University study’ and a twin study, among others, as supporting evidence, again each describing a narrow, single finding rather than a body of evidence on this specific product.
Our take: the individual studies being referenced are generally real and published, which puts this a notch above products that fabricate research entirely. But stitching together the most dramatic-sounding relative percentage from each of several different, unrelated single studies, on different strains, in different populations, and presenting them together as if they describe what buying this one product will do for you, is a classic cherry-picking pattern. None of these percentages describe a clinical trial of this finished six-strain formula. Treat 427 percent and 120 percent as descriptions of specific prior research on individual strains, not as a promise about your own results.
Ingredients Breakdown
The formula centers on six named probiotic strains plus a modest dose of green tea extract for a gentle metabolism boost. Doses are given in general terms (a stated total CFU count) rather than a full per-strain breakdown, though the vendor states each strain is present at 3 to 6 billion CFU.
| Ingredient | Claimed Benefit (per manufacturer) | Evidence Grade |
|---|---|---|
| Lactobacillus gasseri | Reduces belly fat, shrinks fat cells, blocks dietary fat absorption | B: genuinely one of the better-studied probiotic strains for waist circumference and body fat in small human trials, though effect sizes are modest and not universal across studies |
| Lactobacillus rhamnosus | Reduces hunger and cravings, supports fat loss, supports healthy blood sugar | C to B: some human trial support, notably in a well-cited Canadian study in women specifically, with more mixed results in men |
| Lactobacillus plantarum | Helps the body produce CLA, which may reduce new fat cell formation | C: mostly early-stage and animal research for this specific fat-blocking mechanism, weaker direct human weight-loss evidence |
| Lactobacillus paracasei | Reduces food intake, modifies fat storage via ANGPTL4 | C: limited early human evidence, promising but not well replicated at scale |
| Bifidobacterium animalis | Speeds gut transit time, reduces bloating | B for general digestive transit and regularity, which is a real and reasonably well-supported probiotic benefit; C for any direct weight-loss claim |
| Bifidobacterium breve | Blocks fat-storage signal (LPS), shrinks fat cells | C: plausible mechanism from animal and early human research, not yet well established at the level of a confident recommendation |
| Green tea extract (approximately 2.8mg caffeine per serving) | Gentle metabolism support without a strong stimulant dose | C to B: reasonable evidence for a modest thermogenic effect, and the low caffeine dose is a genuinely honest, non-exaggerated detail on this page |
This is a more scientifically grounded ingredient list than most ClickBank weight-loss pitches we cover, several of these strains do have real, specific human research behind them for body composition or digestive outcomes. The gap is entirely between the individual-strain research and the marketing’s implication that combining them in one capsule reproduces those percentage results for you.
Pros and Cons
Pros
- Named, specific probiotic strains rather than a vague ‘proprietary blend,’ with real published research behind several of them individually
- Uses delay-release capsules designed to survive stomach acid, a genuine, well-understood formulation detail for probiotic products
- Low, disclosed caffeine content (about 2.8mg per serving) rather than a hidden stimulant dose
- Straightforward once-daily dosing
- A long money-back guarantee window (6 months on the main sales page) gives you real time to judge whether it is doing anything for you
Cons
- The 427% and 120% headline statistics come from single, unrelated studies on individual strains, not from a trial of this finished product, and are presented in a way that implies more than they can support
- ‘Poop out the fat’ is a real but heavily oversimplified description of ANGPTL4 biology, and reads more like a marketing hook than an accurate summary of a complex metabolic pathway
- No clinical trial on the finished six-strain-plus-green-tea formula as a whole
- Customer testimonials on the page are not independently verifiable
- The guarantee window is stated inconsistently across the vendor’s own pages (6 months on the main landing page, 3 months on a related order-bump page), so confirm the exact terms before you rely on it
- Upsell structure escalates your dose over a 90-day ‘challenge’ (1, then 2, then 3 capsules per day), which increases total cost and total caffeine intake beyond what the base listing implies

Is It Legit or a Scam?
This is a real product from an established ClickBank vendor (Peak Biome) with a multi-product catalog, named and verifiable probiotic strains, a stated refund window, and third-party manufacturing quality claims (certificate of analysis, third-party testing for microbials and label accuracy). We would not call this a scam. The honest criticism is about marketing exaggeration, not fraud: the statistics are cherry-picked from unrelated single studies rather than a real trial of this product, and the underlying biology is oversimplified into a catchy ‘poop out the fat’ hook. That is a common pattern across the supplement industry generally, not unique to this vendor, but it still means you should not expect to personally see anything close to a 427 percent or 120 percent improvement.
FAQ
Will this really make me ‘poop out’ the fat I eat?
The underlying biology (ANGPTL4 reducing fat absorption) is real, but the effect size in humans from a probiotic blend like this is modest and not established at the dramatic scale implied by the marketing copy. Treat any noticeable digestive changes as a possible side effect of adding a new probiotic, not proof the core mechanism is working exactly as described.
Is this the same as a regular digestive probiotic?
It uses similar delay-release capsule technology to many general digestive probiotics, but the specific strain selection (particularly L. gasseri and L. rhamnosus) is chosen for studies tied to body composition rather than digestive comfort alone, plus it adds a small amount of green tea extract for a mild metabolism effect that a plain digestive probiotic would not include.
Are there side effects?
Probiotics can cause temporary gas, bloating, or changes in bowel habits, especially in the first few weeks, which is consistent with normal probiotic adjustment rather than a specific red flag for this product. The roughly 2.8mg of caffeine per serving is low enough that it is unlikely to cause stimulant-related side effects for most people.
What is the refund policy?
Stated as 6 months on the main sales page. A related order-bump page on the same site states 3 months, so confirm the exact terms that apply to your specific order at checkout.
Final Verdict
Of the three new weight-loss reviews we published this round, this is the strongest on the evidence, several of its named probiotic strains have genuine, specific human research behind them, the caffeine dose is honestly low, and the guarantee window is unusually generous. It loses points for leaning on a set of cherry-picked, single-study percentage statistics (427 percent, 120 percent) that describe unrelated prior research rather than this product, and for boiling down a genuinely complex metabolic pathway into an oversimplified ‘poop out the fat’ pitch. We are scoring it 5.5 out of 10: a reasonable middle-of-the-pack pick if the probiotic angle interests you, but not a product to expect dramatic, guaranteed results from.
