Electrolytes supplementation for 70-120 km of cycling.

After using Hymalayn salt as my electrolytes booster, I have experimented with salt pills and was surprised to find out that the previous acted better in preventing muscle cramps toward the end of my rides. I was expecting that an engineer product would perform better. Could you please shed some light on that topic? Thank you.

Is nicotine dangerous?

Where do all the nicotine replacement products come from?
