The
More, The Mightier:
Is Your Probiotic Supplement Packing
a Powerful Enough Punch? |
 |
While the majority of information about the benefits
of probiotics focuses primarily on Lactobacilli or Bifidobacteria
(two of the most prevalent strains in a healthy human digestive
tract), your digestive system is actually home to more than 500
different species of bacteria, or literally trillions of individual
microorganisms.
What’s more, if
this number were ever reduced to just one type of bacteria (no
matter how potent), your body would soon be overrun with pathogenic
invaders. Indeed, no single species of beneficial bacteria can
provide enough defensive measures on its own to protect the digestive
tract from infection. This is precisely why scientists worldwide
agree that when supplementing with probiotics, it is always best
to incorporate more than one species.
Recently when researchers
in Taiwan examined the effectiveness of probiotics with regard
to combating H. pylori, a type of bacteria linked to stomach
ulcers, they found that a combination of both Lactobacilli
and Bifidobacteria types worked better than using either type
on its own. (AJCN, Vol. 80: 3, 737-741, 9/04) The study also
revealed that to effectively combat H. Pylori, probiotics need
to be taken continuously. When the participants in the study
stopped taking their supplements, the H. pylori staged a destructive
comeback.
Results of this particular study have scientists
convinced that fine-tuning probiotic treatment to address problems
such as H. Pylori is preferable to using antibiotics, which
can often do more harm than good. Although traditional antibiotic
treatment has proven effective, researchers are concerned that
the misuse or overuse of antibiotics can eventually destroy
the good bacteria along with the bad.
A Beneficial Partnership
The enhanced benefits of taking a probiotic
supplement with both Lactobacilli and Bifidobacteria are proving
so powerful that researchers are considering ways to use those
benefits to treat liver disease.
A collaborative study conducted
by researchers in China, England and Australia found that administering
such synbiotic supplements (those containing Lactobacilli and
Bifidobacteria, as well as added fiber – a
prebiotic) to those suffering from cirrhosis of the liver reversed
many of the signs of minimal hepatic encephalopathy (MHE). MHE
is liver damage linked to brain dysfunction, which, if left untreated,
can lead to changes in behavior and neuromuscular function, as
well as decreased intelligence. (Hepatology, 5/04)
The study
revealed that roughly half of the people given synbiotic preparations
showed a reversal of their MHE difficulties. They also had
more acidity in their digestive tract (which kills off pathogens)
as well as fewer toxins circulating in their bodies. MHE is
often accompanied by an overgrowth in the digestive tract of
the harmful bacteria E. coli and Staphylococcus. However, researchers
found that these pathogens were also reduced when people took
synbiotic probiotic supplements or fermentable fiber.
Choosing
the Right Probiotic
Because maintaining a healthy balance of
beneficial bacteria in your digestive tract is essential to
your overall health, choosing the right probiotic formula is
crucial. Select a supplement that contains both Bifidobacteria
and Lactobacilli, one that mirrors the body’s natural balance – more
Bifidobacteria than Lactobacilli.
Studies highlight the fact
that when these bacteria, in the proper ratio, work together
in the gut to preserve health, the potential benefits are enormous.
They help the body fight off a host of diseases, including
viruses. Further, scientists in Slovenia have demonstrated
that together, Lactobacilli and Bifidobacteria “…have the ability
to decrease viral infection by establishing the antiviral state
in macrophages, by production of NO and inflammatory cytokines
such as interleukin 6 and interferon-gamma.” (Anti Viral
2007 Sep;75(3):266-74) This means that Lactobacilli and Bifidobacteria
provide substantial support for the body’s anti-virus arsenal.
Together with the immune system, they enable the body to stay
healthy in a world filled with harmful, disease-causing microorganisms. |
