Best Nutrients/Ways to stop major cramping?

Drink a lot of water (more than 4 liters a day). Eat around 4 bananas a day. Might also be due to a salt imbalance in your body, in which case a salt tablet might also help.

Stretch a lot, and warm up properly. If you are someone that is just genetically prone to cramps (like I am), there is only so much you can do that can prolong the amount of time before you get the cramp (but there isn't much you can do to completely prevent them).

Best of luck regardless and I hope you get your problem sorted out.
