[QUOTE=sakura_girl;1001215]Wow. Shouldn't you be concerned about that much magnesium in water?[/QUOTE]
Well I was in a heat wave so I was drinking several litres of mineral water a day. I only bought the Slovenian water because the local supermarket had sold out of San Pellegrino! I drank about a litre of it one day and my bowels told me I was overdosing. I'd say it's a healthy cure for constipation.
The extra magnesium seemed to help my energy levels tho - I didn't see the temperature outdoors fall below 28C during the last 6 days of the holiday, and it was 34-38 C throughout most of the day. I was walking at least 10 km each day sightseeing, so felt I should make extra effort to get plenty of electrolytes.
I'm inclined to agree with Jack Kruse, that generally most of us can't get enough magnesium.
Hmmmm do we lose magnesium when we're sweating?
