If you look at the instructions on the side of a half gallon of Epsom salts, it says to empty two thirds of it for pain relief! So if you think a handful of expensive bath salts is gonna get the job done, think again. You need to buy a lot in order to get any real relief. I go to Amazon and buy 20 pounds for about 30bucks, which is actually pretty reasonable. It will also last you a long time if you also add sea salt and Himalayan salt, which is what I plan to combine.
