I take potassium supplements every so often because I do so much martial arts training and my muscles are often severely fatigued. I find I am less tired the day after an intense workout when I take a potassium supplement along with a Calcium/Magnesium/Phosphorous liquid combo. I also take potassium when I am sick as it dries up excess mucus in the body. I have low blood pressure to begin with so I have to be careful not to overdo the potassium supplementation! I can tell it lowers my blood pressure somewhat.
