For muscle cramps / spasms I use potassium and magnesium.

"Potassium is a nutrient that helps facilitate muscle contractions. It is a neuromuscular transmitter that provides communication between muscles and nerves. This communication breaks down when potassium levels are low, and muscles can “get stuck” in a contracted position that we feel as spasms or cramps. Historically, potassium has been associated with bananas. However, they are not the best nutrient source, providing just nine percent of your daily recommended intake. Instead, consider one of the following five foods listed below to help with muscle cramps:

Sweet potatoes
Melon
Cooked Spinach
Nuts
Beans"

I use "No Salt" for seasoning which is 100% potassium. It is in most groceries, made in Germany. There is also "light salt" that is 50-50 sodium / potassium.
I also take magnesium taurate daily. With those two, I have eliminated the cramps. Hope it can help you.
