My spouse suffered with massive leg cramps every night, even after a day of normal physical activity.
Our family doctor suggested Citracal, an OTC supplement containing Calcium & Vitamin D.
It gave some relief for a while, but then the charley-horses came back, stronger & more painful than before.
I researched leg cramps & found that Vitamin E was the silver bullet.
So my spouse stopped taking Citracal & took 2 geltabs of Vitamin E, 400IU, every night instead.
Within 3 days, the leg cramps disappeared.
That was over a year ago, my spouse always takes it every night, & it still works wonders.
我有段時間天天小腿抽筋，吃了維生素E大概兩三次就好了。
