I picked up a box of Liqumins Electrolyte Stamina Power Pak (Orange Blast) at Vitamin Shoppe. The product claims: "feel the difference or your money back". I thought, why not try it.
Typically after exerting myself in the heat, I usually drank a whole lotta water to the point of feeling nauseous. If I didn't then I'd get cramps. I'd about electrolyte supplements, but had not tried them.
With a heat wave here in the East there was no better time to test it. I took a fast paced five mile walk Sunday morning. Afterwards I drank one glass of water with one packet. Tasted bad. Then "I" had not planned for it, but I mowed and did other yard work for about 1 1/2 hours - yes, wife initiated :). Then I drank one more glass with one packet. The drink after the walk had an amazing effect on me and so did the 2nd one. Good stuff.
I'm pretty sure that I've been needing electrolytes rather than drinking more water. Nice to stumble upon something like this. The box has 32 packets (6.5 g each) [9 g on my scale]. I'm going to take enough for 3x per day on my hikes coming up this summer.
