I'm glad I was steered onto this post from another post. I never add salt and I don't often eat selections high in salt. Based on info from the original post, this might explain the muscle twitches I've gotten from time to time since going low carb. My borderline High BP has dropped to normal since going low-carb. Perhaps I should try adding a little more salt to my diet and see if that will get rid of the twitches and still keep my BP normal.
