As many of you are aware, there was a catastrophic water main break on Saturday that is currently affecting dozens of communities in Eastern Massachusetts, For those of you living in a restricted water zone I want to offer my advice as to safe water-use procedures.

First, make sure to consult the MWRA website regularly, as they offer detailed instructions on boiling and treating water, safe food preparation, etc.

And because many of our patients have weakened digestive tracts and immune systems to begin with, I want to make some suggestions to strengthen the bowel lining, if it should be exposed to abnormal bacteria and parasites. These are basically the same recommendations that I make when people travel to areas with questionable water supplies.

One is a strong probiotic. We use either TruFlora (needs refrigeration) or UltraFlora DF (does not need refrigeration). One capsule twice daily during times of exposure should suffice.

Second, we use the herbal antiparasitic supplement Para-Gard. Two capsules AM and PM after meals is the proper dose.

Third, we use a pre-biotic, L-Glutamine, to strengthen the bowel wall. I recommend L-Glutamine FOS powder, 1/2 teaspoon twice a day, in water that has been at a rolling boil for two minutes, of course.
