Athletes spend hard-earned cash on sports drinks and energy gels in an attempt to stave muscle cramps, but it might be smarter to reach for the French’s. Yellow mustard has been used as a home remedy for leg cramps for decades and many athletes are finding their way back to the tasty yellow packets for a quick cure. It could be the acetic acid, turmeric, or vinegar in the mustard that does the trick. Or it could be the salt. Your typical teaspoon of mustard has 200mg of sodium, which is known to alleviate exercise-induced cramps.
