I take a variety of tablets (some with added Bs and folate), some just plain magnesium, occasionally a magnesium and potassium combo. I weigh about 135lbs and the pills containing between 350 - 400g (only one a day, taken at night) are enough for me. I think I would get a major attack of the runs if I took more...

I must say, though, I do tend to agree with Hutchinson: you seem to be taking an awful lot and too much can give you problems, too.

Perhaps if you had a deficiency, you now need to restock your stores, but long-term I would cut down. There've been threads in this sub-forum about magnesium before and somebody posted something which will tell you how much you need per kg/lb of body weight. Heavier people need more.

Also, as it is a muscle relaxant, I would personally avoid taking it in the morning. I take it at night and I have no troubles getting to sleep. If I stop taking it, I start to get cramps easily and my mild arrhythmia starts to return with a vengeance.

For me it's an absolute must-have supplement, but you can overdo it!
