Our quality promise

A probiotic formula lives or dies on quality. Live bacteria are fragile, doses must be accurate, and contamination is not an option. Here is how LeanBiome is made, tested and held to standard, from raw ingredient to sealed bottle.

🏭

FDA-inspected facility

LeanBiome is manufactured in the United States in a facility that is FDA-inspected and GMP-certified, meaning it follows Good Manufacturing Practices for consistency, cleanliness and documentation at every step.

🔬

Third-party tested

Every batch is verified by an independent lab for both potency and label accuracy, so the 20 billion CFU and the ingredient amounts on the label are what you actually receive.

💊

Delayed-release capsules

The DRcaps capsule is acid-resistant, protecting the live bacteria from stomach acid so far more of them arrive alive in the gut where they do their work.

Purity and clean sourcing

What we leave out matters as much as what we put in. LeanBiome is vegan-friendly and free from gluten, dairy, soy, nuts, crustaceans, GMOs and BPAs. We do not pad the formula with unnecessary binders, artificial colors or cheap fillers to bulk out the capsule. Each raw ingredient is screened on arrival, and the branded actives, such as Greenselect Phytosome, come with their own documentation of identity and standardization. If an ingredient cannot be verified, it does not go in.

Potency that survives the shelf

Probiotic counts can fade over time if a product is made or stored carelessly. We formulate to hold a meaningful, accurate count through the product's life, and we give every bottle a two-year shelf life from manufacture. Cold-chain awareness, sensible packaging and fresh stock all play a part. This is one of the strongest reasons to buy from this official store rather than a third-party reseller: we control how the product is handled right up to the moment it ships to you, so the count on the label is the count in your hand.

Why the delivery format is a quality decision

It is easy to treat the capsule as an afterthought, but for a probiotic it is central. An ordinary capsule dissolves in the stomach, exposing fragile bacteria to acid strong enough to destroy most of the dose before it reaches the gut. The delayed-release DRcaps we use are engineered to stay intact through that acidic stretch and open further down the digestive tract. The practical effect is that far more living bacteria arrive where they are needed. A high count on the label means little if the bacteria never survive the trip, so we treat the capsule as part of the formula, not the wrapper around it.

Testing the green tea, too

Quality is not only about the bacteria. The Greenselect Phytosome green tea extract is a branded, standardized ingredient, which means its active polyphenol content is measured and consistent batch to batch rather than left to chance. The phytosome wrapping that makes those polyphenols absorbable is part of what we pay for and verify. Generic green tea powder is cheaper, but it cannot promise the same absorption or the same consistency, and consistency is what lets a formula perform the same way every time you take it.

The short version: made in an FDA-inspected GMP facility, third-party tested for potency and accuracy, delivered in acid-resistant capsules, and free from the usual fillers and allergens. See the bundles.

Use it sensibly

Quality also means honesty about use. Take two capsules a day and do not exceed the suggested serving. Keep the bottle sealed in a cool, dry place out of direct sunlight, and out of reach of children. If you are pregnant, nursing, taking medication or managing a health condition, speak with your doctor before starting. LeanBiome is a dietary supplement designed to support a healthy gut and healthy weight as part of a sensible lifestyle, not to replace medical care.
