My Irritable Bowel Syndrome (IBS) Was Much Improved After I Removed CHLORAMINE From My Drinking Water I always noticed that my irritable bowel syndrome (IBS-D) was greatly improved when I left the UK and visited Paris. I had considered many possible explanations for this, but had yet to find an answer. Recently, however, I discovered that my local water utility company puts chloramine (as well as chlorine) in my tap drinking water. Chloramine is a disinfectant (chemical formula NH2Cl) added to the drinking water supply in some areas of the US, the UK, Canada and Australia, in addition to chlorine. Unlike chlorine, chloramine is not easily removed from your tap water by boiling, nor by letting the tap water stand in an open bottle overnight (aeration). So this means that chloramine remains in the drinking water even when you boil the kettle to make a tea or coffee, and even when you cook food with boiling water. Chloramines are also not removed from tap water by the activated carbon filters that are used to remove chlorine; so even if you have a tap water filter, this will not protect you from chloramine. I had a theory that the chloramine in my water might be exacerbating my IBS, and might explain why my IBS improves when I leave the UK and visit Paris (in Paris they use neither chlorine nor chloramine, preferring ozone as the drinking water disinfectant). Research on the negative health affects of chloramine is scant, though there are many anecdotal reports on the Internet of health problems caused by chloramine in tap water, particularly problems with the skin (some reports given here: 1, 2). Apparently, many people only notice the ill health affects of chloramine when they travel abroad, or when they travel to a different part the country (say on a business trip), where there is no chloramine the water, and notice that while they are away, certain chronic ailments or symptoms they have just disappear. So I had an idea that chloramines in my water supply might be affecting my intestines, and worsening my IBS. Thus I decided to test my theory that chloramine was exacerbating my IBS symptoms by removing all chloramine from my drinking and cooking water. You can quickly and easily remove the chloramine from your drinking water simply by adding vitamin C to the water. You just need to add 10 mg of vitamin C to neutralize each liter of water. (Alternatively 20 mg of sodium thiosulfate will also neutralize the chloramine in a liter of water). References: 1, 2, 3, 4. So all I did was add a very small amount of vitamin C to all the tap water I drink and use for making tea and coffee, and to all the tap water I use for cooking. Within a couple of days of doing this, my IBS symptoms were noticeably improved, and have remained much improved. So anyone here who is battling IBS or other bowel symptoms, check to see if your local water supplier is putting chloramine into your drinking water, and if so, consider trying this simple vitamin C neutralization technique to remove the chloramine. Your IBS / bowel symptoms may be significantly improved within days. Note: the improvement in symptoms happens fast, within a day or two of removing chloramine, so it does not take long to see if removing chloramine is going to be of benefit for you.
