Support for your Digestive Health and optimal immune function – Flora Biotect™

Dr. Fuhrman, M.D.’s probiotic provides natural support for digestive health and optimal immune function.

Flora Biotect™?helps to restore the natural balance of good bacteria in the intestinal tract. These good bacteria, which protect us from toxins, strengthen our natural defenses, and improve nutrient absorption, can be depleted by medications, poor diet, stress, and other negative environmental influences.

Flora Biotect™ supports digestive health by supplying a multi-strain probiotic blend that provides 20 billion active cultures per capsule.

Its unique delivery system design enables the live bacteria to escape destruction in the stomach, so they are effectively released in the small intestine to support immune function, digestive health, and bowel regularity.

Multi-strain probiotic blend providing 20 billion active cultures per capsule

Includes short-chain fructooligosaccharides, natural prebiotic fiber that stimulates the growth and activity of beneficial bacteria

Packaged in targeted-release acid-resistant capsules, which resist stomach acid and ensure that a maximum number of viable cells are delivered into the intestinal tract, where they can fully exert their beneficial effects

No need for refrigeration. Each capsule is sealed individually in nitrogen-purged blister packs to ensure optimum freshness and potency.

Vegan; does not contain gluten, dairy, soy, or GMOs

Manufactured by a GMP-certified and FDA-regulated facility

Key Ingredients

Bifidobacterium lactis (Bl-04)
Bifidobacteria are broadly recognized for their key role in the human intestinal flora throughout life. B. lactis Bl-04 has been shown to beneficially modulate immune function and support respiratory health.

Bifiodobacterium longum (BB536)
This proprietary, well-researched probiotic strain provides a natural defense against episodic digestive upsets, including constipation, diarrhea, abdominal discomfort, gas, and bloating. It helps support immune function, maintain gut bacterial balance, promote the production of beneficial substances by the microbiome, and downregulate the immune system’s response to seasonal challenges.

Lactobacillius acidophilus (La-14)
An extensive collection of studies supports the health-enhancing probiotic properties of L. acidophilus La-14. Studies suggest L. acidophilus La-14 benefits immune function and produces substances that inhibit the growth of unfavorable bacteria.

Lactobacillius rhamnosus (Lr-32)
L. rhamnosus promotes and maintains digestive tract health. It is recommended for the maintenance of regularity and normal gastrointestinal function.

Saccharomyces boulardii
In multiple experimental studies, this beneficial probiotic yeast has been effective in supporting normal bowel function and maintaining regular intestinal transit.
