Re: Does chlorinated drinking water kill beneficial gut bacteria?

Hello Brian,

Excellent question! I have not come across any scientific studies on the subject but I can see your logic. Of course, the amount of chlorine in chlorinated drinking water is very minimal. If it weren't we would suffer from toxicity issues, and it would certainly give us diarrhea because our digestive systems also contain beneficial microbes.

So, I am frankly not overly concerned about it causing a significant reduction of hindgut microbes in the horse's digestive tract. Nevertheless, if the horse develops loose manure, or has an unthrifty appearance, providing a probiotic is a good idea. One like Synbiotic EQ or Equine Gold for the older horse, would be worthwhile.

All the best,

I have heard that drinking chlorinated water can be bad for our (humans) health. Has there been any studies on the effects of chlorinated drinking water on horse's digestive systems? My thought process leads me to think that chlorinated water would harm beneficial hind gut bacteria, thus causing carbohydrate overload and excess toxins to enter the blood stream. Any thoughts?
