Just when you thought it was safe to go out lol. Still Scottish Mountain Water from the Co-op!! Thought I would move from my Brita filtered water to bottled water BUT, not thinking I should read the label, I did and look what I found mg per litre: Calcium <55mg; Magnesium >16mg; Potassium <2.0mg; Sodium <15mg; Bicarbonate >240mg; Sulphate <28mg; Nitrate <6mg; Chloride <11mg.
Shall I move onto mineral water is or this stuff OK?
Filtered water is kinder to the environment, & probably kinder to your purse.
Mineral water may clog up your kettle, & make your tea scummy.
A filter lasts 3 to 4 weeks, depending on your water hardness, so the maths for my water consumption, in an area where it's not hard, means it costs me under £1 a week, much less as I usually buy filter's when they're half price. I'd spend more than that a day, if I were to buy decent quality mineral water, with no BPA's in the plastic.

I personally like the Berkley water filter or reverse osmosis but with reverse osmosis you need to add the minerals back into your water. The berkely water filter may be expensive to buy at first but it is a good water filter.
NOTHING removes the most dangerous compound, fluoride, unless it specifically says so in the instructions.
the benefit of drinking good mineral water, is that you are not drinking in the fluoride that's contained in tap water. I discovered that the water from our water authority has quite a high fluoride content. And yes there are no filters that remove fluoride, except the ones you have fitted to your taps. But I'm not sure how expensive they are. And as Glynisrose says fluoride is not good, especially for the thyroid !!!!!
Only a few water companies in the UK add fluoride. Most don't.
en.wikipedia.org/wiki/Fluor...
All water companies analyse their water constantly. They occasionally publish their findings on their websites. Google links to "water quality" or similar words and include the name of your water company in the search. For example, the water in the London Zoo area has this analysis :
secure.thameswater.co.uk/wa...
secure.thameswater.co.uk/wa...
The pdf in the second link explains how to read the pdf in the first link.
In the report I've linked to, the maximum fluoride allowed by law is 1.5 mg/L. The average amount in the London Zoo area during the time period the analysis covers was 0.143 ng/L, so it is well within the legal maximum.
Thames Water doesn't add fluoride to their water so it is the natural level found in the water they use.
Water and levothyroxine
