ProTren Probiotics

ProTren Probiotics is a professional-strength probiotic product line used by BioCorrect Nutrition to help our clients with digestive issues.  ProTren specializes in manufacturing the highest pharmaceutical-grade quality probiotic supplements, setting a global standard of excellence in the dietary supplements industry.

Natasha Trenev introduced the term “probiotics” to the United States when she immigrated here in 1954.  She and her company support scientific research throughout the world demonstrating the health benefits of their chosen bacteria strains.

  • Lactobacillus acidophilus, NAS super strain
  • Lactobacillus bulgaricus, LB-51 super strain
  • Bifidobacterium bifidum, Malyoth super strain
  • Bifidobacterium infantis, the most beneficial bacteria predominant in healthy infants.

Why Choose ProTren Probiotics?

Leadership, Quality, Viability and Scientific Support.  There’s a lot of hype from companies about numbers of different bacteria strains provided and who has more CFU’s in every capsule.  When it comes to better health, simple is almost always best.

It’s a fact, probiotic bacteria strains don’t play nice with each other.  They fight each other for dominance as they colonize in the intestines.  Until one strain wins the dominance battle, the battle can cause gas and digestive distress.  Fewer strains that colonize best in different locations in the digestive tract keep things simple and effective.

Three Is Best

ProTren focuses on three probiotic bacteria strains, all super strains chosen for their key properties.  One that colonizes best in the upper or small intestine (Lactobacillus acidophilus).  One that works best as food passes along the intestinal tract (Lactobacillus bulgaricus).   Finally, one that colonizes best in the large intestines (colon) and finishes the digestive and elimination process (Bifidobacterium bifidum).

A forth strain only offered as a single strain formulation, Bifidobacterium infantis, is the predominant probiotic strain in healthy infants.  It’s thought to have co-evolved with humans because of its unique ability to digest human breast milk oligosaccharides.  It can be helpful for colicky infants with gas and gastric distress.

The good news is these single probiotic strains once established, fight against pathogenic flora, yeast and fungus that cause health issues.  ProTren offers single strain probiotic options to selectively address individual regions of the digestive tract, and the 3-in-1 Trenev Trio which delivers the three key bacteria strains together to colonize separately along the digestive tract.

Viability – The Trenev Process

The Trenev Process® is a unique proprietary technology that ensures unmatched survivability and stability of the live probiotic bacteria. This cutting-edge technology uses an oil-matrix system to micro-enrobe the beneficial bacteria keeping them separated, non-competitive and virtually 100% protected from the stomach’s gastric juices.

Bacteria are commonly antagonistic and will fight for survival, therefore multi-strain probiotic products must be created in a way that maintains the separation of each individual strain. ProTren mixes together a maximum of only three organisms and uses this unique oil-matrix technology to keep them separate and non-competitive.

Trenev Trio Oil Matrix System

In addition to protecting the bacterial strains from one another, the oil-matrix also protects the live bacteria during their passage through the acidic stomach. This survivability has been validated through third-party testing by an internationally acclaimed European institute at pH 1.8 for 60-90 minutes. The protective oil-matrix delivery system results in virtually 100% survivability, for over an hour in corrosive stomach acid, of the three probiotic bacteria found in ProTren’s Trenev Trio and additional protection is provided by the two-piece hard gelatin capsule.

Bifidonate 60 probiotics
ProTren BIFIDONATE can help keep your colon in perfect working order.

ProTren BIFIDONATE powders and capsules are the most important beneficial bacteria for human health, according to Japanese research.

  • A healthy intestinal flora
  • Digestion and absorption
  • Production of B vitamins
  • Overall daily regime of probiotic intake
  • Re-population of the colon with bacteria essential for good health

Don’t let a sluggish colon make you miserable.  Residues and wastes can build up in the colon.  BIFIDONATE can help keep your colon in perfect working order.

  • Helps in liver function and detoxification.
  • Helps in the production of B Vitamins in the gastrointestinal (GI) tract.
  • Acts as a antimicrobial agent by producing acetic and lactic acid, to lower the pH of the intestines and inhibit undesirable bacteria.
  • Helps to inhibit the colonization of the intestines by invading pathogens with which it competes for nutrients and attachment sites.
  • May suppress harmful bacteria that are associated with age-related, geriatric diseases.

Bifidobacterium bifidum, Malyoth Super Strain, 2 billion cfu per serving

Recommended for adults and children over two years of age.

SIZES: 1.75 oz.  powder, 3.0 oz. powder, 60 capsule and 90 capsule bottles

Superdophilus 60 probiotics
ProTren SUPERDOPHILUS aids in digestion and absorption.

ProTren SUPERDOPHILUS powders and capsules are the natural way to maintain a healthy intestinal flora no matter what season of the year.

  • Digestion of dairy products by assisting with lactose metabolism
  • Small intestine health

ProTren SUPERDOPHILUS also aids in digestion and absorption.  It is also a resident organism in the oral cavity, the vaginal tract and part of the urinary system.

  • Helps destroy invading hostile bacteria by producing natural antibiotic substances.
  • As an antimicrobial, may suppress undesirable microorganisms in the intestines, by some competitive means, e.g. production of lactic acid and other inhibitory substances.
  • May help reduce levels of potentially harmful bacterial enzyme activity in the large intestine
  • Helps lessen the production of hostile yeasts
  • Helps maintain and support a healthy immune system

Lactobacillus acidophilus, NAS Super Strain, 2 billion cfu per capsule or 1/2 level teaspoon

Life Start Pro probiotics
Optimal digestion system for infants, expecting, or nursing mothers. 

ProTren LIFE START PRO® Bifidobacterium infantis, the most beneficial bacteria predominant in healthy infants.

B. infantis is the predominant gut bacteria in healthy, breast-fed infants.

  • Produce acetic and lactic acids and small amounts of formic acid from carbohydrates.  These organic acids increase the acidity of the intestines, thereby inhibiting undesirable bacteria.*
  • Optimized digestion*
  • Prevent the colonization of the intestines by pathogens by competing for nutrients and attachment sites.*
  • Assist nitrogen retention and weight gain in infants.*
  • Inhibit bacteria that convert nitrates to potentially harmful nitrites.*
  • Produce vitamins in the B-complex family.*

B. infantis is one of the most predominant bacteria found in the gut of healthy, full-term, breastfed infants.  B. infantis was recently named the ‘champion colonizer of the infant gut’ by researchers at U.C. Davis because of its unique ability to digest human breast milk oligosaccharides.  In a 1980 German study, B. infantis was the predominant beneficial bacteria found in infants.  Alarmingly, since that time, researchers have found a decline in the numbers of B. infantis found in infants, including breast-fed infants.

Bifidobacteria and the specific substances they secrete can protect the intestinal mucosa in infants.  When the microflora of infants becomes disturbed from oral antibiotic therapy, vaccinations, convalescence or sudden weather changes, the levels of Bifidobacteria decline and lower digestive health.  The use of Bifidobacterium infantis NLS can help with the nutritional restoration of the intestinal microflora.

Bifidobacterium infantis NLS Super Strain, 1 billion cfu

SIZES: 1.25 ounce
