We're all familiar with antibiotics and their intended goal: to kill the harmful bacteria which cause illness. But, the use of antibiotics create a conundrum because they do not discriminate between harfmul and beneficial bactera; and, because of their unselective nature, antibiotics also kill the beneficial bacteria that live in our digestive tract as well. This has the potential to cause other issues such as, diarrhea, upset stomach, or lowered intestinal immunity.

The human body uses over 100,000 enzymes -- about a dozen are responsible for digesting the food we eat. As we age, our body's production of these digestive enzymes decreases by 1 to 2 percent per year. Aging also decreases the number of beneficial probiotic bacteria in our intestinal tract.

Trufiber does not produce excessive gas like other fiber products!  Most soluble fiber products cause gas and bloating.  TruFiber is less gassy due to the molecular structure of SunFiber (PHGG, Partially Hydrolyzed Guar Gum.)  PHGG has an intermediate size (20,000 MW) and only probiotics and other non-gassy bacteria are able to feed off of it.  Other soluble fibers that are smaller in Molecular Weight (MW) such as FOS can be eaten by many types of intestinal...
