Pick up some taurine.

Potassium is going to compete with magnesium.. the predominate issue is magnesium loss with dehydration. It is absolutely essential for two different actions: the first is Ca+2 pump action for calcium efflux from SR and the second is motor unit Mg dependent Na/K ATPase activity.

You need a LOT of magnesium. Try taking it 4-5x throughout the day with meals, 250 mg shots of magnesium citrate. This ion participates in some 2000 different reactions in cells and is usually lacking vitamin supps, as manufacturers presume that dietary intake is sufficient, which it often is NOT when dehydration from high protein loads is combined with exercise and weight loss supps.

BTW, go look at vetteman's MP test log on bulknutrition.com - I left salient comments about the action and efficacy of MP.

I have a strong feeling that once word of this supps gets around, it will be a winner.
