A few years ago when I was trying to get my body sorted out and having regular blood tests it seemed my iron levels were through the roof for no apparent reason. The Doc asked me if I was taking iron supplements, which I was not. In conversation with a friend, she asked me if I was drinking water from the Red Spring in Glastonbury where I live close to. I said No, I get my water from Littlewell absolutely delicious it is too. Then I realised that the Littlewell spring fed the Red Spring. It is called the Red Spring because it is packed with iron, and I had to stop drinking it. Might be worth those of us suffering with iron deficiency trying to locate a natural source in spring water. Glastonbury spring water is bottled and sold, but I believe that is taken from the White Spring, which I think is loaded with calcium. Just might be worth looking at the mineral analysis in bottled waters - some actually contain fluoride!!
