Re: Where to buy salt tabs?
Kristine: the only salt tabs that I have ever seen in a store are Thermotabs, which are salt tablets (not capsules). A couple of my local independent drug stores (the ones that are left!) carry them (or will order them for me), none of the chain drugstores carry them. The good/bad thing with Thermotabs is that they crumble and dissolve--good if you want to put them ahead of time in your water bottles to have a salt mix handy, bad if you want to carry them with you in tablet form--I did that once in a marathon and wound up with a pocket full of salt dust. Now if I'm "carrying", I use Succeed capsules because they have more sodium per capsule than some other brands, and I was able to order them on lline without any problems (though I don't remember where from).
If you can't get anything quickly and just want to have salt mixed in your water bottles that you are carrying on your bike this weekend, table salt will do. Most of the tablets/capsules that we are talking about have a mix of sodium and other electrolytes, but I know for myself that I'm a lot more deficient in sodium than other minerals (I don't ordinarily add salt to my food, and I'm a vegetarian who eats a lot of high-potassium foods).
