Too much potassium is very bad for you. I had also read on this forum to take it for energy loss but then they started saying the dr's were saying not to take it. I take the magneseum in the afternoon, after I eat my lunch.
On my magnesium it says to take 3 pills once a day equaling 400mg and thats 100% of your daily value.....soooo I just take 2 (making it about 267 mg), plus the magnesium in my multivitamin (50 mg) so my grand total a day is 317-leaving me room for what is in foods.
