Best for
- Buyers who want to see CFU counts and milligram amounts before choosing a probiotic
- People who want a long trial window: 180 days from the order date
- Anyone looking for a decaffeinated green tea ingredient in capsule form
Less ideal if

- Shoppers who want a single-bottle trial; the smallest package is two bottles
Key ingredients
- Lactobacillus gasseri (25 mg, 10 billion CFU)The label's lead probiotic, which the seller presents as a 'lean bacteria' species. No strain code is printed.
- Lactobacillus rhamnosus (10 mg, 5 billion CFU)The second individually dosed probiotic, also grouped by the seller with its 'lean bacteria'.
- Proprietary probiotic blend (10 mg, 5 billion CFU)Seven species with no individual amounts: Lactobacillus fermentum, L. paracasei, L. plantarum, Bifidobacterium bifidum, B. lactis, B. longum and B. breve.
- Inulin from chicory root (200 mg)Dietary fiber the seller says is included to feed the probiotic strains.
- Green Tea Phytosome (300 mg)Decaffeinated green tea extract bound to a sunflower phospholipid; the sales page calls it Greenselect Phytosome.
- Sphaeranthus indicus (300 mg)Flowering plant the seller added in a later version of the formula and pitches, with mangosteen, for fat storage and fat burning.
- Garcinia mangostana pericarp (100 mg)Mangosteen fruit rind, added alongside Sphaeranthus indicus as part of what the seller calls a formula upgrade.

LeanBiome or Biome? Sorting out the name
Most people search for LeanBiome, but the official Lean for Good sales page and its bottle images now use the name Biome. The ClickBank checkout behind the page still runs under the leanbiome name, and the Supplement Facts label linked from the page is the formula covered here. If you land on a page selling "Biome by Lean for Good", you are looking at the same product this review describes.
The LeanBiome Supplement Facts label, line by line
Unusually for a weight-management supplement, the label gives numbers. One serving is two capsules and a bottle holds 30 servings. Per serving, the Supplement Facts label lists:
- Lactobacillus gasseri: 25 mg, 10 billion CFU
- Lactobacillus rhamnosus: 10 mg, 5 billion CFU
- Proprietary blend: 10 mg, 5 billion CFU combined, made up of Lactobacillus fermentum, L. paracasei, L. plantarum, Bifidobacterium bifidum, B. lactis, B. longum and B. breve
- Inulin from chicory root: 200 mg
- Green Tea Phytosome: 300 mg of decaffeinated green tea leaf extract in a phospholipid complex from sunflower
- Sphaeranthus indicus: 300 mg
- Garcinia mangostana (mangosteen) pericarp: 100 mg
That adds up to 20 billion CFU from nine bacterial species. The remaining ingredients are capsule and processing materials: hydroxypropyl methylcellulose, microcrystalline cellulose, magnesium stearate, silicon dioxide and gellan gum.
Two limits are worth knowing. Seven of the nine species share one pooled blend, so their individual counts are unknown. And the label names species without strain codes, so you can't confirm the bacteria are the same strains used in the studies the sales page cites.
What the sales page claims about "lean bacteria"
The pitch rests on the idea that lean and overweight people carry different gut bacteria, and that adding the right "lean bacteria" helps with hunger, cravings, metabolism and fat storage. Those are the seller's claims. To support them, the page describes published studies on L. gasseri, L. rhamnosus, L. fermentum and Greenselect Phytosome.
Read those summaries with the page's own details in mind. Each study tested a single ingredient, not LeanBiome. The L. gasseri study it describes gave the bacteria in milk rather than in capsules, and the green tea study it describes paired the extract with a calorie-controlled diet. The FAQ also explains that Sphaeranthus indicus, Garcinia mangostana and inulin were added later to strengthen the formula, and it credits the first two with reducing fat storage. None of that tells you what the full nine-species formula does in people.
Two capsules before breakfast: how the seller says to take it
The official directions are two capsules a day with a sip of water, preferably in the morning before breakfast, which makes one bottle a 30-day supply. The seller uses DRcaps delayed-release capsules and says they are designed to carry the bacteria past stomach acid. It also quotes a two-year shelf life.
On duration, the page argues that the longer you take it, the better it works, points out that the studies it cites ran for up to about three months, and recommends its three- and six-month packages on that basis. That is sales guidance rather than a results timeline for this product.
Side effects, allergens and who should ask a doctor first
The official site does not publish side-effect data. Its footer asks anyone who is pregnant, nursing, taking medication or living with a medical condition to consult a physician before use, and that is sensible advice for any probiotic. If your immune system is weakened by illness or treatment, talk to your doctor before starting one; the NIH's NCCIH notes that the risk of harmful effects from probiotics is greater in people with severe illnesses or weakened immune systems.
For allergies, the seller describes the formula as vegetarian and vegan-friendly and free of gluten, sugar, nuts, soy, crustaceans and dairy. Check the label yourself if you react to chicory or sunflower, because the inulin comes from chicory root and the green tea phytosome uses a sunflower phospholipid.
LeanBiome is a dietary supplement. The seller's own disclaimer says its products are not intended to diagnose, treat, cure or prevent any disease.
The 180-day guarantee and the fine print behind it
The shipping and return policy sets out the terms:
- The 180 days count from the order date, not the delivery date.
- You return any remaining unopened bottles; opened or empty bottles do not need to go back.
- Return shipping is on you, the bottles must arrive undamaged, and the packing slip goes in the box to Lean for Good in Tallmadge, Ohio.
- Before shipping, contact support by email or phone with your name, the email used to order and your order confirmation number.
- Refunds take up to 5–7 business days once the returned bottles arrive.
One wording issue: a line in the policy says you get back your original purchase only, while the next section says contacting them within 180 days earns a full refund that includes shipping and handling. Ask support to confirm which applies before you send anything.
Where LeanBiome reviews go wrong in search results
In a September 2026 check of US Google results for "leanbiome reviews", every organic result on page one was an anonymous page hosted on Amazon's S3 file storage rather than the seller or an independent reviewer, and Google's AI summary pointed to a PDF on a university web domain as the "official website". The seller's actual site is bestleanlife.com, and the page says the product will never be sold in stores.
The official packages are two, three or six bottles. The three- and six-bottle packages include two bonuses, among them a smoothie recipe e-book, and the six-bottle package has the lowest per-bottle price and free US shipping, according to the official site. Smaller packages add a shipping fee, which is higher outside the US. It is a one-time charge with no rebilling, and you can check the current price on the official website.
Who LeanBiome suits, and who should look elsewhere
LeanBiome suits you if label transparency matters, you're happy taking two capsules before breakfast, and you want six months to decide, keeping in mind that only unopened bottles go back and return postage is yours.
Look elsewhere if you want strain codes, a single-bottle trial or research on the finished formula, or if you're pregnant, nursing, on medication or immunocompromised and your doctor hasn't approved it. For comparison, see our weight management reviews or the PrimeBiome review, a probiotic gummy taken once a day. If LeanBiome fits, you can review the current packages on the official Lean for Good page.
