I had heard that tums helps with cramping so I bought some and put them in my saddle bag. Years later, they were still there. I have heard calcium helps with cramping, so that’s where the idea of using tums comes from.
I am not big on taking a large amount of electrolytes to ward off cramps. But it has become clear that I am really sensitive to how much water I drink relative to electrolytes. I have definitely had cramping due to drinking too much plain water. This particularly happens on the first couple of hot rides of the year. I think in the future I might stop taking electrolyte pills altogether and just have something in every bottle of water or other drink. If you need the quantity of electrolytes in a pill, you are way behind.
