I bought this to treat extremely severe leg and thigh cramps. One night I had to call 911 for myself because I couldn't move. While trying to talk to the 911 dispatcher I was in so much pain that I couldn't put a sentence together properly. I thought "NEVER AGAIN" so I researched a way to get enough potassium into my system so that I wouldn't cramp up 3 times a week.
Anyway, I add a 1/4 teaspoon of this powder into a glass of tea 3 times a day. Before work, after lunch, and about an hour before bed. It's been a month or so since I started doing that and I haven't had so much as a flutter in my leg and thigh muscles. This is a good product, dissolves easily, and my muscles feel loose with no crampiness or tightness at all. So much better than always wondering when the next time with severe cramps is going to happen. Even my arthritic knees feel much better. :)
