PreforPro is unlike other prebiotic ingredients that require large doses and several days to begin working.~ John Deaton, Ph.D.

Understanding Prebiotics and Probiotics

Probiotics and Prebiotics Defined
The Food and Drug Administration (FDA) defines prebiotics as “a non-digestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, and thus improves host health.”1 The FDA defines a probiotic as “a living microorganism which, when administered in adequate amounts, confer health benefits to the host.”2 These microorganisms are usually bacteria and are sometimes referred to as “healthy”, “friendly”, “good” or “beneficial” bacteria. Probiotics are microorganisms similar to those that naturally exist in the gut3 . The idea is that in order to stay healthy, we must maintain a delicate balance of microflora (i.e. a mix of different bacteria) in the gastrointestinal tract. That balance can easily be upset if unwanted bacterial populations become predominant in the GI tract.

Balancing Bacterial Flora
A proliferation of harmful bacteria in the gut can rob your body of the essential nutrients it needs by consuming those nutrients that your body would normally absorb. Symptoms of unbalanced bacterial flora include4 :

  • Abdominal Pain
  • Indigestion
  • Bloating
  • Food Allergies
  • Malnutrition

In many cases, good bacteria have a difficult time displacing the unwanted bacteria and require help; this is where prebiotics come into play5 .

Prebiotics: Benefits and Drawbacks
Prebiotics are generally fibers or starches (e.g., oligosaccharides) that have been shown to be beneficial; however these can have some drawbacks6 , including:

  • They require large doses to be effective.
  • They can cause flatulence.
  • They are sensitive to their specific environment.
  • They only work in the colon.

About PreforPro

As a result of extensive research, the scientists at Deerland Enzymes have developed a novel prebiotic that supports the growth of healthy bacteria in the gut through a mechanism that is not fiber or starch-based. PreforPro addresses the drawbacks of typical prebiotics on the market; benefits include:

within hours (not days).
the small and large intestines.
by varying gut environments.
of probiotic species.

The Science

PreforPro has been shown under both physiological conditions in vitro and in vivo to preferentially promote the growth of beneficial Lactobacillus, Bifidobacterium and Bacillus subtilis strains when competing with undesirable bacterial strains. The effects are achieved at small doses within hours, in both the small and large intestine.

Frequently Asked Questions

What is PreforPro?
PreforPro is a novel prebiotic that supports the growth of healthy bacteria in the gut through a mechanism that is not fiber or starch‐based. Benefits include: 1) it is efficacious in small doses (15mg) within hours (not days), 2) it functions in both the small and large intestines, 3) it does not cause flatulence, 4) is not affected by varying gut environments, 5) it works with a broad spectrum of probiotic species.

How does it work?
PreforPro destabilizes the cell wall of bad bacteria, resulting in release of nutrients into the environment which can then be utilized by probiotics and the good bacteria of the GI tract. Because of the novel nature of the product and its patent-pending status, a Non-Disclosure Agreement must be signed in order to receive full details regarding the mechanism of action. Contact Deerland Enzymes for information.
